Some patients experience vision decline after LASIK due to natural age-related changes or unforeseen complications.
However, such cases are relatively rare, and most people maintain significant improvements in eyesight for years after surgery.
This blog dives into the potential reasons behind vision changes post-LASIK, explores solutions, and provides guidance for those considering or recovering from the procedure.
What Causes Vision Decline After LASIK?
Natural Aging of the Eyes (Presbyopia)
LASIK corrects refractive errors like nearsightedness, farsightedness, and astigmatism, but it doesn’t stop the natural aging process of the eyes. A very common age-related vision condition is presbyopia, which typically starts affecting people after age 40. It occurs when the eye’s lens becomes less flexible, making it hard to focus on nearby objects.
Even if your vision was perfect after LASIK, presbyopia can still develop later in life, requiring reading glasses or alternative treatments.
Progressive Eye Conditions
For some individuals, underlying or undiagnosed progressive eye conditions, such as keratoconus (thinning of the cornea), may lead to vision deterioration after LASIK. This condition changes the shape of the cornea and could affect the precision of the original correction.
Changes in the Original Prescription
LASIK surgery reshapes the cornea based on your pre-existing refractive error. However, for a small percentage of patients, vision prescriptions can change over time due to environmental or health-related factors like diabetes or prolonged screen exposure.
Dry Eye Syndrome
LASIK can sometimes exacerbate or trigger dry eye syndrome, a condition where your eyes cannot produce enough tears to stay hydrated. Chronic dryness may cause blurriness and discomfort, potentially leading patients to perceive their vision as having declined after surgery.
Regression of LASIK Outcome
Regression happens when the cornea shifts slightly after surgery, reducing the original corrective effect over time. This occurrence is relatively rare but might result in the partial return of nearsightedness, farsightedness, or astigmatism.
How Common is Vision Decline After LASIK?
Vision decline after LASIK is statistically rare, with over 95% of LASIK recipients achieving 20/20 vision or better, according to studies conducted by the American Refractive Surgery Council.
For most, LASIK provides long-lasting results. However, a small percentage of patients may experience complications or see changes in vision over the years.
Signs and Symptoms to Watch Out For
- Blurriness or reduced clarity after previously clear vision
- Difficulty focusing on near or distant objects
- Increased sensitivity to light or glare, especially at night
- Persistent eye discomfort from dryness or irritation
If any of these symptoms occur, consult your eye care provider for an evaluation to determine possible causes and solutions.
Steps to Tackle Vision Decline After LASIK
Regular Eye Exams
Regular eye check-ups are essential for monitoring and maintaining your eye health, especially for LASIK patients. Early detection of changes can help prevent further complications.
Your optometrist or ophthalmologist will assess refractive changes and suggest corrective measures, such as glasses, medication, or enhancements.
Artificial Tears and Hydration
If dry eye syndrome is part of the problem, over-the-counter artificial tears, omega-3 supplements, or other hydrating treatments can provide relief. For severe cases, your ophthalmologist may recommend prescription dry eye therapies.
LASIK Touch-ups or Enhancements
For patients experiencing regression or prescription changes, a touch-up procedure, also known as LASIK enhancement, might be a viable option. However, this is only possible for those who still meet the corneal thickness and health criteria post-primary LASIK.
Addressing Progressive Conditions
If conditions like keratoconus or other corneal issues arise, treatment options such as corneal cross-linking can help halt progression. Speak to an eye specialist about specific treatment possibilities.
Managing Age-Related Vision Changes
For presbyopia or other age-related issues, additional treatments may help restore comfortable vision. Common options include multifocal contact lenses, reading glasses, or surgical alternatives like lens replacement surgeries (RLE).
Preventive Measures to Maintain LASIK Results
Protect Your Eyes from UV Light
Wear sunglasses that offer 100% UV protection so the cornea stays healthier after LASIK. UV rays can accelerate corneal aging and related complications.
Maintain Healthy Habits
- Stay hydrated and follow a diet rich in fruits and vegetables to support eye health.
- Manage underlying conditions like diabetes or hypertension, which can affect vision stability.
Limit High-Impact Activities Early On
During the recovery phase after LASIK, avoid activities or sports with high impact that could harm your eyes. Proper care in the critical early weeks can play a significant role in preserving long-term results.
Reduce Digital Eye Strain
Prolonged screen time can lead to digital eye strain, causing temporary discomfort. Implement the 20-20-20 rule (look at something 20 feet away for 20 seconds every 20 minutes) to minimize stress on your eyes.
Should Vision Decline Stop You From Getting LASIK?
For most people, LASIK offers life-changing results, bolstering their quality of life with clear vision and reduced dependence on glasses or contact lenses. Concerns like regression, presbyopia, or other factors are typically manageable as they occur gradually over time.
That said, it’s essential to set realistic expectations beyond the surgery itself. Consult a trusted ophthalmologist, review your eye health and lifestyle, and discuss long-term vision care needs to determine if LASIK is the best fit.
When To See an Eye Specialist?
If you notice any sudden, unexplained changes in your vision after LASIK, contact your ophthalmologist immediately. Early intervention is critical for addressing complications or regression effectively.
Your specialist can help:
- Diagnose the root cause of any vision decline.
- Recommend corrective measures (glasses, touch-ups, etc.).
- Provide insights into maintaining overall eye health going forward.
Move Forward with Care and Confidence
LASIK is a proven, effective solution for correcting many vision problems, and significant vision decline post-surgery remains the exception rather than the rule.
By understanding potential challenges like age-related vision changes or regression and preparing accordingly, you can enjoy the benefits of LASIK for years to come.
If you’re considering LASIK or currently navigating vision concerns post-surgery, consult an eye care professional to explore the best options tailored to your needs.
