LASIK (Laser-Assisted in Situ Keratomileusis) is one of the most commonly performed and longest-standing laser eye surgery methods. It offers an effective and reliable solution for individuals who prefer not to wear glasses or contact lenses. In LASIK treatment, a flap is created in the cornea, and laser is applied underneath to precisely correct vision problems, providing a fast recovery process.
LASIK has been successfully used for years to treat refractive errors such as myopia, hyperopia, and astigmatism. With advancements in modern laser technology, the procedure time has decreased and patient comfort has improved.

How Is LASIK Eye Surgery Performed?
-
Preparation: The patient is provided with special attire. The surgeon performs final checks.
-
Anesthesia: Local anesthesia is applied with eye drops. The procedure is painless.
-
Flap Creation: A very thin flap is created on the corneal surface and gently lifted.
-
Laser Application: An excimer laser is used to reshape the underlying corneal tissue to correct the vision error.
-
Flap Replacement: After the laser application, the flap is replaced and naturally reattaches without stitches.
-
Medication: Antibiotic and moisturizing drops are applied.
-
Final Check: A post-treatment eye exam is performed, and the patient is discharged.
The procedure takes approximately 10–15 minutes. Total time in the clinic is around 2 hours.

When Are LASIK Results Visible?
Clear vision typically begins within the first 1–2 days after LASIK. Many people can return to work the next day. Visual quality reaches its maximum within a few weeks. Temporary symptoms such as light sensitivity, glare, and dryness may occur initially but will subside over time.
More than 95% of patients achieve their expected results. In rare cases, additional correction may be needed. Such cases are monitored by the physician and planned accordingly if necessary.
