Lasik
What is Lasik?
LASIK (Laser-Assisted In Situ Keratomileusis) is a popular type of refractive eye surgery that corrects vision problems such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. It involves reshaping the cornea (the transparent front part of the eye) so that light entering the eye can be properly focused onto the retina, leading to clearer vision.
When to consult a doctor for Lasik?
The steps involved in diagnosing whether LASIK is appropriate for you: Comprehensive Eye Exam, Corneal Thickness Measurement, Corneal Topography and Wavefront Mapping, Tear Film Evaluation, Pupil Dilation & General Health and Eye Health History.
You should consult a doctor if:
- Cloudy or blurry vision
- You Rely on Glasses or Contact Lenses: If you're dependent on corrective lenses for daily activities and want to reduce or eliminate the need for them.
- Your Vision Prescription Has Stabilized: If your prescription has not changed significantly for at least a year, you may be a candidate.
- You Experience Irritation from Contact Lenses: If contact lenses cause discomfort or dry eyes, LASIK could be a more convenient option for vision correction.
- You Are in Good General Health: If you don’t have chronic conditions that could affect healing (e.g., autoimmune disorders) and have healthy eyes free from infections or diseases.
- You Want Permanent Vision Correction: If you're looking for a long-term solution to refractive errors and want to discuss the potential risks and benefits with a specialist.

Frequently Asked Questions
Most patients notice improved vision within 24-48 hours. Full recovery may take a few weeks, and patients are typically advised to avoid strenuous activities or swimming during this time.
LASIK is not painful. Numbing eye drops are used during the procedure, and most patients feel only mild pressure. Some discomfort or dryness may be experienced post-surgery.
Common side effects include dry eyes, glare, halos around lights, and temporary visual disturbances. Rare complications may include infection, over-correction, or under-correction of vision.
