Can Dry Eyes Cause Blurred Visions After Lasik?


Millions of individuals have benefitted from the common refractive procedure known as LASIK (Laser-Assisted In Situ Keratomileusis), which has helped them see more clearly and lessen their need for glasses or contact lenses. Although LASIK is typically secure and successful, some patients may develop post-operative issues, including dry eyes and visual problems. In this post, we will examine the connection between dry eyes and fuzzy vision following LASIK surgery and possible causes, safeguards, and treatment options. So, Can Dry Eyes Cause Blurred Visions After Lasik? Let’s check!


Common Side Effects of LASIK Surgery

LASIK surgery involves reshaping the cornea to address refractive defects, including nearsightedness, farsightedness, and astigmatism. Most patients notice better eyesight within a few days after the relatively short and painless surgery. However, like any surgical surgery, LASIK has certain potential adverse effects, with dry eyes being among the most prevalent.


Dry eyes following LASIK.
When the eyes do not generate enough tears or evaporate too rapidly, the ocular surface does not have adequate moisture, leading to dry eyes. The delicate corneal nerves that cause tears to form can be damaged during LASIK surgery. Additionally, reducing corneal sensitivity during the procedure could impact tear film dynamics.


Vision Blurring and Dry Eyes
Vision blurring and other painful symptoms, including burning, itching, redness, and a gritty sensation in the eyes, are all caused by dry eyes. The uneven tear film distribution over the cornea, which causes light to scatter rather than concentrate precisely on the retina, is a common source of this blurriness. As a result, patients may suffer variations in visual acuity, particularly in low-light situations or when doing visual activities for extended periods.


Causes of dry eyes after LASIK

Following LASIK surgery, several variables might affect the frequency and severity of dry eyes:

a) Pre-existing Dry Eye Syndrome:
Patients with severe dry eyes and blurry vision are more likely to develop these side effects after LASIK.

b) Older patients may produce fewer tears, which makes them more prone to dry eyes after surgery.

c) Due to hormonal influences, women are often more likely to experience dry eyes.

d) Both before and after surgery, dry eye problems might be made worse by windy and dry settings.

e) Some drugs can cause dry eyes as a side effect, elevating the danger of post-LASIK dry eye issues.


Preventing and treating dry eyes and hazy vision


Preoperative examination:
A thorough preoperative examination and patient selection are essential to identify those who already have dry eye diseases. Before LASIK, treating dry eyes can enhance surgical results and lower the chance of post-operative problems.


Patient Education:
Patients must know the risks of dry eyes and hazy vision following LASIK. Understanding the value of post-operative care can improve patient compliance and general satisfaction by emphasizing the need for regular lubrication and prescribed drugs.
Artificial tears or lubricating eye drops are frequently administered following LASIK to assist in keeping the ocular surface adequately moist. These drops relieve dryness and lessen the chance of getting eyesight blurriness.


Punctal Plugs:
Ophthalmologists may employ punctual plugs to obstruct the tear drainage ducts, which helps keep natural tears on the eye’s surface for longer.


Prescription drugs:
To lessen inflammation and encourage the formation of tears, doctors may give anti-inflammatory drugs and cyclosporine eye drops.


Environmental Changes:
Patients can alter their surroundings to lessen the symptoms of dry eyes, such as using a humidifier or avoiding dry or smoky areas.


Rest and Blinking:
Taking frequent pauses while performing visual chores, including reading or using a computer, can reduce eye strain and promote natural blinking, which helps distribute tears.


Can dry eyes cause blurry vision?

After LASIK surgery, dry eyes may result in impaired vision. The cornea is reshaped during LASIK (Laser-Assisted In Situ Keratomileusis), a common refractive procedure, to treat nearsightedness, farsightedness, and astigmatism. Dry eyes are a typical side effect of LASIK, even though surgery is generally safe and successful, especially during the first few weeks after recovery.

The corneal nerves that control tear production may be damaged during LASIK surgery, resulting in less tear production. The dynamics of the tear film may also be affected by reducing corneal sensitivity caused by cutting the corneal flap. As a result, dry eye syndrome could develop if the eyes don’t get enough lubrication and moisture.

After LASIK, vision might become blurry due to dry eyes because of how tears are distributed on the ocular surface.

An optical surface must remain smooth and clean for light to pass through and focus correctly on the retina. The normal tear film maintains it. Vision becomes hazy when tears are unbalanced or insufficient to reflect light appropriately.

The symptoms of post-LASIK dry eyes include gritty sensations, burning, itching, or sensitivity to light. These signs and symptoms might be uncomfortable and make it seem like your eyesight is more hazy. Additionally, the number and quality of tears may be diminished, affecting visual acuity, particularly in dimly lit areas or when engaging in visually demanding activities.

Fortunately, dry eyes and the eyesight that results from them are often just temporary, and they tend to become better as the eyes heal. To treat dry eyes and enhance vision, eye physicians frequently recommend lubricating eye drops or synthetic tears. It is crucial for LASIK patients to carefully adhere to their post-operative care instructions, which include using prescription eye drops appropriately and showing up for follow-up sessions to track the healing process.

Before and after LASIK, treating or preventing dry eyes can improve surgery results and patient satisfaction. Therefore, it is essential to detect those who already have dry eye diseases during a thorough preoperative assessment. Preoperative treatment of these illnesses can reduce the chance of post-LASIK worsened dryness and impaired vision.

Due to decreased tear production and changed tear film dynamics, dry eyes might result in impaired vision following LASIK surgery. For LASIK patients, prompt diagnosis and effective treatment of dry eye symptoms are crucial to a quick recovery and the best possible visual results. Professionals in the field of eye care are crucial in helping patients navigate the post-operative time, suggesting lubricating eye drops, and offering essential encouragement for a positive LASIK experience.



By enhancing eyesight, LASIK surgery is a revolutionary operation that has enhanced the quality of life for countless people. It’s important to understand that dry eyes, a typical side effect, might cause post-operative impaired vision. Patients and healthcare professionals should collaborate to recognize pre-existing dry eye diseases, put preventive measures into place, and successfully treat dry eye symptoms.

Consult your ophthalmologist immediately if you continue to have severe or chronic blurred vision following LASIK. Most patients can get excellent visual results and benefit from LASIK surgery with little discomfort by adhering to the advised post-operative care and integrating suitable management measures.
