Types of LASIK & Laser Procedures
LASIK and laser vision correction include several advanced techniques designed for different eye conditions and corneal profiles.
Each procedure uses specific technology to address unique visual needs.
Below are the main types of laser procedures performed.
SMILE PRO
SMILE PRO is an AI-enabled robotic laser procedure designed for people with high screen time or digital eye strain. It is a flapless and minimally invasive technique. For full indications, advantages and candidacy details, see SMILE PRO Eye Surgery in Delhi.
EPI-LASIK
EPI-LASIK is a surface procedure similar to PRK and is suitable for patients with thinner corneas. The epithelium is gently separated before laser treatment.
LBV (Laser Blended Vision)
LBV is recommended for patients around age 45 who want both near and distance vision correction. The non-dominant eye is adjusted for near vision, while the dominant eye is corrected for distance.
SMILE (Small Incision Lenticule Extraction)
SMILE is a blade-free technique that uses a small incision to remove a lenticule and reshape the cornea. It offers fast recovery and minimal discomfort.
PTK (Photo Therapeutic Keratectomy)
PTK removes superficial irregular tissue from the cornea using an excimer laser. It is often used for corneal scars, surface irregularities or recurrent erosions.
YAG Laser
The YAG laser is used for treating secondary cataracts (posterior capsule opacification). It is a quick, non-invasive laser procedure performed after cataract surgery if needed.
SLT (Selective Laser Trabeculoplasty)
SLT is used for open-angle glaucoma to reduce eye pressure. It targets pigmented cells in the drainage system without damaging surrounding tissue.
PRP (Pan Retinal Photocoagulation)
PRP is a retinal laser treatment often recommended for diabetic eye disease. It helps prevent further vision loss by treating abnormal blood vessels in the retina.
FEMTO-LASIK (Intralase LASIK)
Femto-LASIK is suitable for patients with thin corneas or those seeking a blade-free flap creation method. Recovery is typically faster compared to traditional techniques.
| Procedure | Suitable For | Blade / Blade-Free | Recovery Time | Key Feature |
|---|---|---|---|---|
| SMILE PRO | High screen-time individuals | Blade-free | 1–2 days | AI-enabled robotic system |
| EPI-LASIK | Thin corneas | Surface procedure | Few days | PRK variation |
| LBV | Age 45+ | Laser-based | Adjustment period | Near + distance correction |
| SMILE | Myopia | Blade-free | 1–2 days | Small incision method |
| PTK | Corneal surface issues | Blade-free | Case-dependent | Removes irregular tissue |
| YAG Laser | Secondary cataracts | Blade-free | Immediate | Posterior capsule clearing |
| SLT | Open-angle glaucoma | Blade-free | Quick | Lowers eye pressure |
| PRP | Diabetic retinopathy | Blade-free | Varies | Retinal stabilization |
| FEMTO-LASIK | Thin corneas | Blade-free | Fast | High precision flap creation |
What Is Intralase LASIK (Blade-Free LASIK)?
Intralase LASIK is a blade-free laser procedure that creates the corneal flap using a femtosecond laser instead of a mechanical blade.
This allows precise flap creation and reduces the chances of flap-related complications.
How Intralase LASIK Works
- A femtosecond laser creates a thin, uniform flap on the cornea
- The flap is gently lifted to expose the underlying layer
- An excimer laser reshapes the cornea to correct refractive error
- The flap is placed back without stitches and naturally adheres during healing
Examples of refractive errors treated:
- Myopia (near-sightedness)
- Hyperopia (far-sightedness)
- Astigmatism (irregular curvature)
Why Intralase Is Considered More Precise
- The laser flap thickness is more consistent
- There is no blade involved, reducing mechanical risks
- Custom flap depth and diameter can be programmed
- The procedure offers more predictability in patients with unique corneal shapes
📌 Medical fact: Comparative studies have shown that femtosecond laser–created flaps are typically more uniform and have fewer flap-related complications than microkeratome (blade) flaps in LASIK.
Source: peer-reviewed femtosecond vs. microkeratome LASIK studies and American Academy of Ophthalmology clinical reviews.What Intralase LASIK Can Correct
Intralase addresses vision problems caused by corneal shape issues, including:
- Near-sightedness
- Far-sightedness
- Astigmatism
It provides freedom from glasses and contact lenses for distance vision. Age-related near vision changes (presbyopia) may still require reading glasses later in life.
Key Features of Intralase LASIK
- Blade-free flap creation
- High accuracy and repeatability
- Suitable for patients with thinner corneas compared to traditional flap methods
- Reduced risk of flap irregularities
What Is Individualised LASIK (CustomVue Technology)?
Individualised LASIK is a customised laser vision correction technique that uses advanced diagnostic systems to create a treatment plan tailored to each eye. It measures unique optical imperfections and corneal characteristics to deliver more precise results than standard LASIK.
How Individualised LASIK Works
Individualised LASIK combines multiple technologies to analyse the eye in detail:
- WaveScan WaveFront™ captures the eye’s unique optical signature and detects tiny imperfections that standard tests cannot measure.
- Pentacam imaging creates a 3D map of the cornea, showing its thickness, curvature and elevation.
- The VISX STAR S4 IR Excimer Laser uses this personalised data to reshape the cornea with high accuracy.
These systems work together to deliver treatment based on the exact characteristics of your eye rather than a generalised model.
Why Individualised LASIK Is More Precise
CustomVue technology adjusts the treatment based on:
- Corneal irregularities
- Pupil size
- Wavefront aberrations
- Refractive error distribution
- Light behaviour inside the eye
This leads to more accurate visual correction and better night-time clarity in suitable candidates.
Who Benefits Most from Individualised LASIK
Patients who may benefit include:
- People with irregular or asymmetric corneas
- Those with higher-order aberrations detected on WaveFront
- Patients seeking improved clarity in low-light conditions
- Individuals with vision issues not fully corrected by standard LASIK
CustomVue treats myopia, hyperopia and astigmatism with enhanced precision.
Key Features of Individualised LASIK
- Personalised treatment for each eye
- Detailed imaging through Pentacam
- High accuracy with WaveFront-guided correction
- Potential improvement in night vision quality
- Reduced risk of undercorrection or overcorrection
Benefits of Intralase LASIK
Intralase LASIK offers more precision and consistency compared to traditional blade-based LASIK because it uses a femtosecond laser to create the corneal flap. This improves safety, accuracy and overall visual outcomes in suitable candidates.
Higher Precision in Flap Creation
The femtosecond laser creates a flap with uniform thickness, smooth edges and accurate dimensions. This reduces the chances of flap-related irregularities and improves predictability.
Examples of benefits:
- Better centered flap
- More consistent healing
- Stable vision during recovery
Lower Risk of Mechanical Complications
Since no blade is used, certain mechanical risks associated with microkeratomes are avoided. This makes the procedure more controlled and reduces the chance of flap complications.
Reduced Need for Retreatment
The accuracy of Intralase reduces the chances of undercorrection or overcorrection. As a result, many patients require fewer enhancements compared to older LASIK methods.
Improved Comfort and Recovery
Blade-free flap creation often leads to smoother healing and better comfort for the patient. Most individuals experience quicker clarity and less discomfort during the early recovery period.
Possible Reduction in Dry Eye Symptoms
Studies suggest that Intralase LASIK may reduce the likelihood of certain dry eye symptoms after surgery. This is because the laser creates a more controlled flap, which may preserve corneal nerve pathways better.
Important: Even with Intralase LASIK, some patients can still experience dry eye after surgery. Overall risk depends on pre-existing dryness, tear film quality and individual healing, so a proper pre-operative dry eye evaluation is essential.
Benefits of Individualised LASIK
Individualised LASIK provides customised vision correction based on the unique optical pattern of each eye. This allows more accurate treatment and may improve visual sharpness, especially in low-light conditions.
Higher Precision Due to Custom Data
The WaveScan WaveFront™ system captures detailed optical measurements. These measurements guide the laser to address imperfections that standard LASIK may not detect.
Examples of higher precision benefits:
- Better contrast sensitivity
- Improved clarity in dim light
- More personalised reshaping of the cornea
Faster Visual Improvement
Many patients notice clearer vision within 24–48 hours after CustomVue LASIK. This is due to the accurate alignment between diagnostic data and laser treatment.
Treatment Tailored to Corneal Shape
The Pentacam system creates a 3D image of the cornea. This allows the laser to account for individual corneal elevations and thickness differences. Patients with unique corneal patterns often benefit from this approach.
Effective for Multiple Vision Conditions
Individualised LASIK can correct:
- Myopia
- Hyperopia
- Astigmatism
- Higher-order aberrations detected on WaveFront
This makes it suitable for people who want more refined vision after surgery.
Enhanced Outcome Consistency
CustomVue tends to reduce the chances of undercorrection or overcorrection. The personalized treatment map helps achieve more stable and predictable visual results.
Bottom line: Individualised LASIK is especially helpful for patients whose detailed wavefront and Pentacam scans show irregularities or higher-order aberrations, and who are looking for sharper, more stable vision, particularly in low-light conditions.
Step-by-Step Procedure – Intralase LASIK
The Intralase LASIK procedure involves pre-operative preparation, a short laser process and a brief post-operative check-up. Each step ensures safety, accuracy and a smooth recovery.
Pre-Operative Preparation
Before surgery, patients follow specific instructions:
- Use antibiotic eye drops 1 day before or on the day of the procedure
- Avoid contact lenses as advised
- Do not use eye makeup
- Keep the eye area clean
- Follow any additional instructions based on test results
These steps prepare the eyes for accurate laser measurements and reduce infection risk.
On the Day of the Procedure
Patients should arrive with a family member or friend for assistance.
After preparation, the patient is taken to the operating area.
Additional antibiotic drops are applied.
The procedure typically begins within 10–15 minutes of entering the surgery room.
During the 5–7 minute LASIK process:
- The patient lies under the laser system
- The surgeon gives step-by-step instructions
- The femtosecond laser creates the flap
- The excimer laser reshapes the cornea
The patient remains awake and comfortable throughout, with the surgeon guiding them at each stage.
Post-Operative Check and Care
Immediately after the procedure:
- A doctor examines the cornea using a slit lamp
- Prescribed eye drops and medications are given
- Post-operative instructions are explained clearly
Patients may return home shortly afterward, following all care guidelines to support healing and comfort.
Note: Most patients experience mild blurriness and light sensitivity for a few hours after surgery, which typically improves by the next day.
Step-by-Step Procedure – Individualised LASIK
Individualised LASIK uses advanced diagnostic systems to measure the unique characteristics of each eye and deliver a customised laser treatment. The process includes detailed imaging, data mapping and precise laser correction.
Corneal Topography by Pentacam
The Pentacam system creates a 3D map of the cornea by rotating a Scheimpflug camera and slit illumination around the eye. This generates multiple radial images that show:
- Corneal curvature
- Corneal thickness
- Elevation patterns
These measurements help identify subtle irregularities and confirm whether the cornea is suitable for customised LASIK. Pentacam data is essential for setting accurate treatment parameters.
WaveScan WaveFront™ Measurement
WaveScan WaveFront™ captures the eye’s optical fingerprint by detecting higher-order aberrations. It measures how light travels through the eye and identifies distortions that standard tests may miss.
Key steps include:
- Capturing detailed optical imperfections
- Processing the data into a treatment map
- Sending digital instructions to the excimer laser
This ensures the laser corrects both common refractive errors and finer visual distortions.
Treatment with VISX STAR S4 IR Excimer Laser
The VISX STAR S4 IR Excimer Laser applies the customised treatment with high precision. It uses the digital instructions from the WaveFront scan to reshape the cornea accurately.
How it works:
- The laser emits a cool ultraviolet beam (typically around 193 nm)
- Controlled pulses remove microscopic layers of corneal tissue
- The flap, created earlier, is repositioned once reshaping is complete
- The system uses active eye tracking to maintain accuracy during each pulse
This technology provides stable and predictable outcomes for myopia, hyperopia and astigmatism.
Important: Eye-tracking systems in modern excimer lasers help maintain accuracy even with slight eye movement, improving treatment consistency.
General LASIK & Intralase Information
LASIK and Intralase LASIK are laser procedures that reshape the cornea to correct myopia, hyperopia and astigmatism. Both methods aim to improve distance vision and reduce the need for glasses or contact lenses.
Below are common questions patients ask about Intralase LASIK and LASIK in general.
Is Intralase LASIK Safe?
Yes, Intralase LASIK is considered a safe and effective laser vision correction option for suitable candidates. It uses a femtosecond laser to create a precise flap, which improves consistency compared to blade-based methods.
How Much Time Does Intralase LASIK Take?
The entire Intralase LASIK procedure usually takes around 15 minutes. The actual laser application lasts only a few seconds, while preparation and positioning take the remaining time.
Is LASIK Better Than Glasses or Contact Lenses?
LASIK provides clear distance vision without the daily need for glasses or contact lenses. Many patients find the convenience and visual clarity beneficial, especially for active lifestyles and peripheral vision.
Is LASIK Surgery Right for You?
LASIK may be suitable if you want to reduce your dependence on glasses and meet all medical eligibility criteria. Your surgeon will perform detailed tests to confirm if your eyes are healthy enough for the procedure.
Can You Go Blind with LASIK?
Severe vision loss from LASIK is extremely rare when the procedure is done on suitable candidates by an experienced surgeon. Your doctor will explain all risks during your evaluation.
Are You Awake During LASIK?
Yes, you remain awake during LASIK, but your eyes are numbed with anesthetic drops so the procedure is comfortable. Most patients feel only mild pressure and can speak with the surgeon throughout the process.
Eligibility & Candidacy
This section covers the most common questions about who qualifies for LASIK and who should avoid the procedure.
Who Is a Good Candidate for LASIK Eye Surgery?
A good LASIK candidate is an adult with stable vision, healthy corneas and no major eye diseases. Typical requirements include:
- Minimum age of 18 years
- Stable prescription for at least the past 6–12 months
- No history of corneal disease
- Adequate corneal thickness
These criteria help ensure a predictable and safe outcome.
Who Are Not Suitable Candidates for LASIK Surgery?
People with thin corneas, active eye diseases, pregnancy-related changes or autoimmune conditions may not be suitable for LASIK. Examples include:
- Autoimmune disease
- Pregnancy or breastfeeding
- Very thin corneas
- History of cataracts affecting vision
- Severe dry eye
Your doctor will determine eligibility through detailed eye tests.
Is There Any Suitable Age for Getting LASIK Done?
LASIK is generally recommended after age 18, once the vision prescription becomes stable. Most surgeons prefer patients between 18 and 40, when refraction is more consistent. Individuals above 40 may need evaluation for age-related near vision changes.
Can I Get LASIK If I Have a Family History of Cataracts?
A family history of cataracts does not automatically disqualify you, but your surgeon may advise against LASIK if early cataract signs are present in your eyes. Conditions like chronic dry eye or glaucoma may also affect suitability.
Why Is LASIK Not Recommended During Pregnancy?
LASIK is avoided during pregnancy because hormonal changes can affect corneal shape and vision stability. Surgery is usually postponed until hormone levels return to normal after pregnancy and breastfeeding.
Can My Number Come Back After LASIK?
Most adults maintain stable results after LASIK, but minor regression can occur in some cases. Patients with higher initial prescriptions may have a slightly higher chance of needing enhancement later.
How Is Femto LASIK Better Than Normal LASIK?
Femto LASIK is more precise because it uses a femtosecond laser instead of a blade to create the corneal flap. This may lead to faster healing, fewer flap-related complications and better visual quality.
Is LASIK Allowed in the Indian Army?
Yes, LASIK is allowed in the Indian Army under specific conditions. Requirements include:
- Surgery after age 20
- Stable refraction for at least six months
- Healthy retina
- Corrected vision of 6/6 in the better eye and 6/9 in the other
Your pre-op tests must meet military medical standards.
Can LASIK Fix Lazy Eye?
LASIK may help if the lazy eye is caused by a refractive error difference between the two eyes. It does not treat all types of lazy eye, so evaluation by an eye specialist is necessary.
Cost & Insurance
This section explains how LASIK pricing works and what patients can expect regarding insurance coverage.
What Is the Cost for LASIK Treatment?
LASIK cost depends on your corneal thickness, refractive error and the type of laser technology required. Each eye has unique parameters, so the doctor recommends the most suitable procedure after examining your reports. You can book a free LASIK consultation to receive an accurate estimate.
What Does Laser Eye Surgery Cost in Delhi?
In Delhi NCR, laser eye surgery typically ranges from INR 50,000 to over INR 1,50,000 for both eyes. The price varies based on:
- Technology used (SMILE, Femto LASIK, CustomVue, etc.)
- Corneal measurements
- Complexity of the refractive error
Advanced, personalised techniques generally fall at the higher end of the range. For a detailed price range by procedure type, you can refer to our Lasik Surgery Cost in Delhi (₹) guide.
Does Insurance Cover LASIK Eye Surgery?
Most insurance companies do not cover LASIK because it is considered an elective vision correction procedure. LASIK is usually not classified as medically necessary unless required for specific rare conditions. Patients typically pay out-of-pocket or use EMI and financing options offered by the clinic.
Procedure & Technical Details
This section answers common questions about how LASIK works, what happens during surgery and what technical factors affect vision correction.
What Is the Procedure for LASIK Eye Surgery?
LASIK begins with numbing drops, followed by the creation of a corneal flap and the reshaping of the cornea using a programmed excimer laser. The entire process typically takes around 30 minutes for both eyes.
Steps include:
- Numbing the eyes
- Placing a suction ring for stability
- Creating a flap with a blade or femtosecond laser
- Reshaping the cornea to correct refractive error
- Repositioning the flap without stitches
How Long After LASIK Can I Resume Activities Like Driving?
Most patients experience blurry or hazy vision immediately after surgery, so driving should only resume once vision is clear and the doctor approves it. This usually occurs within a day but varies by individual recovery.
How Does the Eye Flap Heal After LASIK?
The corneal flap naturally reattaches without stitches because the corneal tissue seals itself as healing begins. The epithelium covers the flap edges within a few hours, and the flap strengthens over the following days.
What If I Blink or Move My Eye During the Procedure?
Modern LASIK lasers track minor eye movements automatically, so blinking or slight movement does not affect the outcome. The surgeon also uses a device to keep the eyelids open during the procedure.
What If I Sneeze During LASIK?
If a patient sneezes during LASIK, the laser pauses and resumes only after proper alignment is restored. This ensures treatment accuracy and keeps the procedure safe.
Why Do I Have a Vision Problem and How Can LASIK Fix It?
Vision problems such as myopia, hyperopia and astigmatism occur when the cornea’s curvature does not focus light correctly on the retina. LASIK reshapes the cornea so that light focuses accurately, improving visual clarity.
Can LASIK Cure Myopia?
Yes, LASIK can correct myopia by flattening the cornea so distant objects appear clearer. It is also used for hyperopia and astigmatism.
Can LASIK Fix Astigmatism?
LASIK can correct most types of astigmatism by smoothing the irregular curvature of the cornea. The results are long-lasting for suitable candidates.
Can LASIK Give You 20/10 Vision?
Some patients achieve vision sharper than 20/20 after LASIK, but 20/10 results are less common and depend on corneal shape and original prescription. Most patients obtain 20/20 or better.
Can LASIK Fix Night Blindness?
LASIK does not treat night blindness directly but may improve night vision if the underlying cause is refractive error. Other causes, such as cataracts, need separate treatment.
Pre-Operative Tests & Preparation
LASIK requires several diagnostic tests to confirm that your eyes are healthy and suitable for the procedure. These tests help determine corneal thickness, tear stability, refractive error and overall eye condition.
What Diagnostic Tests Are Required Before LASIK?
Doctors perform detailed evaluations to measure corneal shape, stability of vision and tear film quality before confirming LASIK eligibility. Common tests include:
- Comprehensive Vision Analysis to determine your exact refractive error
- Binocular Vision Assessment for patients with alignment or focusing issues
- Tear Film Tests to evaluate dry eye conditions
- Corneal Topography to map corneal curvature and detect irregularities
- Wavefront Analysis to identify higher-order aberrations
- Corneal Thickness Measurement to ensure the cornea is thick enough for safe treatment
- Pupil Size Measurement to predict visual quality after surgery
These measurements guide the surgeon in creating a safe and personalised treatment plan.
Why Is It Necessary to Stop Wearing Contact Lenses Before Surgery?
Contact lenses temporarily change the shape of the cornea, so stopping their use allows the cornea to return to its natural form before measurements are taken. Accurate corneal data is essential for calculating a precise LASIK treatment. Soft lens users typically stop lenses for a few days, while rigid lens users may need a longer break based on the surgeon's advice.
Results, Permanence & Power Range
LASIK improves distance vision by reshaping the cornea, and most patients notice results within the first 24 hours. Some experience continued sharpening over the next few days as the eyes settle.
When Will the Results Start to Appear?
Most patients notice clearer vision immediately after the procedure, with significant improvement within the first 3–4 days. Many people can return to work the next day, depending on their healing speed.
When Will I See Full Results After LASIK?
Clear distance vision typically appears within 24 hours, and stabilization continues over the following days. Your doctor monitors progress during scheduled follow-up visits.
Is LASIK Permanent After the Procedure?
LASIK permanently reshapes the cornea, but the eyes can still change with age, which may affect vision later in life. This age-related change is normal and not caused by LASIK. Some patients may need reading glasses after the age of 40 due to natural presbyopia.
What Is the Power Range That LASIK Can Treat?
LASIK can treat up to +6.00 diopters of hyperopia, although many doctors prefer to treat up to +3.00 or +4.00 diopters for more predictable results. Myopia and astigmatism ranges vary based on corneal thickness and overall eye health.
What Results Can I Expect After LASIK?
LASIK offers clear distance vision and reduces or eliminates the need for glasses or contact lenses for most daily activities. Patients often describe the improvement as immediate and transformative. Mild dryness, halos or glare may occur temporarily during the healing period.
Are There Chances of Needing LASIK a Second Time?
A small percentage of patients may need an enhancement years later if their vision shifts slightly. This is more common in individuals with higher initial prescriptions. Even when regression occurs, vision rarely returns to the original pre-LASIK level.
Side Effects, Risks & Safety
LASIK is considered a safe procedure for suitable candidates, but like any medical treatment, it may involve temporary side effects. Most of these effects resolve as the eye heals.
What Kind of Risks Are Involved in LASIK Surgery?
LASIK has a low complication rate, and most risks are temporary rather than permanent. Possible issues include mild dryness, glare or slower healing in some individuals. These risks are minimized through proper screening and follow-up care.
What Are the Common Side Effects of LASIK?
Temporary side effects may include dryness, halos, glare, mild discomfort or fluctuating vision in the first few days. These symptoms are normal and improve with prescribed eye drops.
Examples of common early effects:
- Scratchy sensation
- Light sensitivity
- Mild irritation
What Is the Recovery Timeline After LASIK?
Most patients experience noticeable improvement within hours and clear vision within a day, with full stabilization occurring over several days. Complete healing varies based on corneal thickness, dryness levels and natural recovery speed. Typical early recovery lasts 6–12 hours for many patients.
What Are the Possible Side Effects or Risks After LASIK?
Some patients may notice temporary glare, halos, dry eyes or double vision shortly after surgery. These effects usually improve as the cornea heals and tear film stabilizes. Doctors monitor recovery during follow-up visits to ensure everything progresses normally.
How Long Do Headaches Last After LASIK?
Some patients may experience mild headaches for 1–2 days as the eyes adjust to clearer vision. Strain from screens, reading or bright light can contribute to temporary discomfort. Avoiding visual stress and using prescribed drops helps reduce symptoms.
Post-Operative Care & Follow-Ups
Proper post-operative care helps the eyes heal smoothly and reduces temporary discomfort after LASIK. Following your doctor’s instructions ensures the best visual outcome.
What Is Post-Operative Care for LASIK Surgery?
Patients may experience mild discomfort, dryness or blurred vision immediately after LASIK, and these symptoms improve as healing progresses. Post-operative care usually includes:
- Avoid rubbing the eyes
- Avoid eye makeup for a few days
- Avoid strenuous activities
- Wear protective eye shields while sleeping (first few nights)
- Use prescribed eye drops on schedule
- Avoid swimming and dusty environments
These precautions support early healing and reduce the risk of infection.
How Many Follow-Ups Are Needed After Surgery?
Most patients have follow-up visits the next day, after one week and after one month to monitor healing. Some may require additional check-ups based on individual recovery. Regular follow-ups help detect dryness, flap stability and visual progress.
Does the Patient Need to Stay at the Laser Centre?
Patients do not need to stay at the centre after LASIK because recovery begins immediately, and most people return home within two hours. Resting with eyes closed is encouraged during the first few hours.
Work, Driving & Routine Life After LASIK
Most patients return to normal activities quickly after LASIK, depending on how fast their eyes recover. Your doctor will guide you based on your specific healing response.
When Can a Person Return to Work After LASIK?
Many people can return to desk work the next day, while others may take a few days based on comfort and visual clarity. The medical team provides activity instructions during the first follow-up visit.
Can LASIK Surgery Be Performed on Both Eyes?
Yes, LASIK is commonly performed on both eyes during the same session for balanced and convenient recovery. This approach is standard unless a medical reason requires separate procedures.
Can You Drive After LASIK?
You should not drive immediately after LASIK, but you may resume driving once your vision is clear and your doctor confirms it is safe. Most patients are ready within a day, depending on how quickly their vision stabilizes.
What Should You Keep in Mind Before Getting LASIK?
Patients should understand the procedure, expected recovery, risks and costs before deciding on LASIK. Pre-surgery tests help determine eligibility and ensure realistic expectations.
How Does LASIK Change Your Lifestyle?
LASIK can significantly improve daily convenience by reducing dependence on glasses or contact lenses for distance vision. Most patients enjoy immediate clarity after waking up and greater comfort during physical activities.
What Happens During the First Week After LASIK?
Vision may fluctuate during the first week as the eyes heal and adjust to the reshaped cornea. Temporary halos, glare or night-vision changes may appear, but these typically improve with time. Patients should avoid smoke, alcohol and caffeinated drinks during this early recovery period.
Daily Activities After LASIK
Daily activities can be resumed gradually after LASIK, depending on the type of activity and the eye’s healing response. Your doctor will guide you based on your specific recovery.
Can I Use a Smartphone After LASIK?
Most patients can use their smartphone within 24 hours, but screen time should be limited during the first day to avoid dryness. Following your surgeon’s advice ensures comfortable early healing.
Can I Watch TV After LASIK?
It is best to avoid watching TV for at least 24 hours after surgery to reduce strain and dryness. Most people return to normal screen use within a day or two.
How Many Days After LASIK Can I Shower?
You may shower after 24 hours, but water, soap and shampoo should be kept away from the eyes for several days. Avoid rubbing your eyes while drying your face.
When Can I Wear Mascara After LASIK?
Eye makeup, including mascara, should be avoided for at least one week to reduce the risk of infection. Healing time varies slightly among individuals.
Can I Sleep on My Side After LASIK?
You can sleep on your side after LASIK, but wearing protective eye shields for the first week prevents accidental eye rubbing. Side and back sleeping are both allowed with proper protection.
Should We Wear Spectacles After Getting LASIK?
Most patients do not need spectacles for distance vision after LASIK, but sunglasses are recommended outdoors to protect healing eyes from UV exposure. In cases of high prescription before surgery, occasional glasses may still be needed later in life.
Lifestyle Habits After LASIK
Certain lifestyle habits should be adjusted temporarily after LASIK to support proper healing and comfort. Your doctor may give specific recommendations based on your eye condition.
Can I Drink Coffee After LASIK?
Coffee should be avoided for the first 24–48 hours because caffeinated drinks can increase dryness and make early recovery less comfortable. Hydration and rest help the eyes heal faster.
Can I Drink Alcohol After LASIK?
Alcohol should not be consumed for at least 24 hours after LASIK because it can worsen dryness and interfere with post-operative medications. Some patients may be advised to avoid alcohol for a few days.
Can I Smoke After LASIK?
Smoking should be avoided for at least two weeks before and after LASIK because it irritates the eyes and increases dryness. Avoiding smoke exposure helps ensure smoother healing.
Does Vaping Affect LASIK?
Vaping can cause significant dryness and may slow the healing process, so it should be avoided after LASIK. Patients should minimize all factors that reduce tear film quality during early recovery.
Can I Cry After LASIK?
Yes, crying is safe after LASIK and does not harm the corneal flap or the healing process. Natural tears can help keep the eyes lubricated and comfortable.
Sports, Swimming & Eye Protection
Physical activities must be resumed gradually after LASIK to prevent irritation or accidental injury during the early healing period. Your doctor may adjust these recommendations based on your corneal thickness and healing progress.
How Long After LASIK Can I Swim?
Swimming should be avoided for at least 3–4 weeks after LASIK to prevent irritation and reduce the risk of infection from pool or seawater. Wearing goggles is recommended when returning to water activities.
Can I Wear Goggles After LASIK?
Yes, goggles can be worn after LASIK and are helpful in protecting the eyes during recovery. They reduce dryness, shield the eyes from wind and prevent accidental rubbing. Most patients use protective goggles for 1–2 weeks after the procedure.
Healing, Drops & Medical Care
Eye drops play a critical role in the healing process after LASIK, and patients must follow the prescribed schedule carefully. Proper after-care ensures smooth recovery and reduces the risk of complications.
What Happens If You Don’t Use Drops After LASIK?
Skipping prescribed eye drops can slow healing and increase the risk of irritation, dryness or infection. Medicated drops help prevent inflammation, while lubricating drops keep the eyes comfortable during recovery. Following your doctor's instructions is essential for safe healing.
Does Your Cornea Heal After LASIK?
Yes, the cornea begins healing immediately after the procedure, and noticeable improvement usually appears within the first few days. The outer layer seals the flap edges within hours, and deeper healing continues gradually. Patients should avoid rubbing their eyes and attend all scheduled follow-up visits.
Miscellaneous / Other LASIK Questions
This section covers additional questions patients often ask during consultations.
What Is the Best Age to Have LASIK Laser Surgery?
The ideal age range for LASIK is typically between 18 and 40 years, when the vision prescription is stable. Younger patients must have stable numbers, and older patients may need evaluation for age-related changes.
Does LASIK Cause Night Vision Problems?
Many patients achieve 20/20 vision after LASIK and report improvement in night vision once healing is complete. Temporary glare or halos may appear early in recovery but usually decrease over time.
What Are the Pros and Cons of LASIK Eye Surgery?
LASIK offers fast visual improvement and long-term clarity for suitable candidates, but it may not be appropriate for everyone.
