Q: What is Lasik?
A: Lasik (Laser-Assisted in Situ Keratomileusis) is a surgical procedure that corrects vision problems, such as nearsightedness, farsightedness, and astigmatism. It involves reshaping the cornea using a laser to improve the eye’s focusing ability.
Q: How does Lasik work?
A: During a Lasik procedure, an ophthalmologist creates a thin flap on the cornea’s surface using either a microkeratome blade or femtosecond laser. This flap is then lifted to expose the underlying corneal tissue. Using another laser called an excimer laser, the surgeon precisely removes small amounts of tissue from the cornea to reshape it according to the patient’s specific prescription. The flap is then repositioned, allowing for quick healing without requiring stitches.
Q: Is Lasik painful?
A: Most patients report feeling little to no pain during their Lasik surgery. Before starting the procedure, numbing eye drops are applied to ensure comfort throughout. Some individuals may experience slight discomfort or pressure sensation but rarely describe it as painful. However, mild post-operative dryness or scratchiness can be expected temporarily after surgery.
Q: Am I eligible for Lasik?
A: Eligibility for Lasik depends on several factors including age (typically 18 years or older), stable vision prescription for at least one year prior to surgery, absence of certain eye conditions (e.g., glaucoma), and good overall eye health. An evaluation by Dr. Hossam Elbarbary, an experienced ophthalmologist will determine your candidacy based on these criteria.
Q: What are the potential risks and complications associated with Lasik?
A: While rare, some potential risks and complications include dry eyes following surgery which usually resolves within weeks; temporary visual disturbances like halos or glare around lights; under-correction or over-correction of vision; infection or inflammation; and the development of corneal ectasia, a condition causing progressive thinning and bulging of the cornea. However, serious complications are extremely rare.
Q: How long does it take to recover from Lasik surgery?
A: The majority of patients experience rapid vision improvement within 24-48 hours after Lasik surgery. Most individuals can resume normal activities, excluding strenuous exercise or contact sports involving eye contact, within a couple of days post-surgery. It is important to follow your doctor’s instructions regarding eye drops, avoiding rubbing your eyes, and attending scheduled follow-up appointments for optimal healing.
Q: Is Lasik permanent?
A: Yes, Lasik provides long-lasting results in most cases. While age-related changes in vision may occur naturally over time (e.g., presbyopia), the structural changes made to the cornea during Lasik are typically permanent.
