LASIK has helped many people achieve clearer vision and reduce their dependence on glasses or contact lenses. However, in rare cases, the cornea may gradually become thinner and structurally weaker after surgery. This condition is known as post-LASIK keratectasia.
Keratectasia can cause the cornea to change shape and become more irregular over time. As a result, patients may experience blurred or distorted vision, increasing astigmatism, or difficulty achieving stable vision with glasses or contact lenses.
What Symptoms Should You Watch For?
Because keratectasia can develop gradually, early changes may be subtle. Patients who have previously undergone LASIK should pay attention to:
- Gradual changes or fluctuations in vision
- Increasing or irregular astigmatism
- Blurred, distorted, or ghosted vision
- Increasing difficulty seeing clearly at night
- Frequent changes in glasses or contact lens prescriptions
- Vision that does not improve as expected with corrective lenses
These symptoms do not necessarily mean that keratectasia is present, but they are reasons to have your eyes evaluated by an ophthalmologist.
How Can It Be Detected?
At JRYN Eye Clinic, a comprehensive examination can assess the condition of the cornea and identify changes that may not be visible during a routine vision test. Depending on the patient’s situation, examinations may include detailed evaluation of corneal shape, curvature, and thickness.
These assessments can help the ophthalmologist determine whether there are signs of corneal instability and whether continued monitoring or further evaluation is appropriate.
Why Early Evaluation Matters
Keratectasia is a condition that can progress over time. Identifying suspicious corneal changes early gives the ophthalmologist an opportunity to monitor the cornea closely and discuss suitable management options based on the patient’s individual condition.
If you have undergone LASIK and notice that your vision is becoming less stable or changing unexpectedly, don’t ignore the change. A comprehensive eye examination can help determine whether the symptoms are related to corneal changes or another eye condition.
At JRYN Eye Clinic, our goal is to support patients not only before vision correction surgery, but also in maintaining their eye health for the years that follow.
Early detection can make a difference—listen to changes in your vision and have them evaluated promptly.
