LASIK (Laser-Assisted in Situ Keratomileusis) surgery is a popular and widely performed refractive surgery used to correct common vision problems like nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.

Here's an overview of the LASIK procedure:

Evaluation: Before the surgery, a thorough eye examination is conducted to assess the patient's eye health, corneal thickness, and refractive errors to determine candidacy for LASIK.

Surgery: During LASIK, the surgeon uses a specialized laser to create a thin flap on the surface of the cornea. This flap is lifted to expose the underlying corneal tissue.

Reshaping the Cornea: Using another laser (an excimer laser), the surgeon reshapes the cornea by removing a precise amount of corneal tissue. This reshaping corrects the refractive error, allowing light to focus properly on the retina for improved vision.

Flap Replacement: After the cornea is reshaped, the flap is placed back into its original position where it adheres naturally without the need for stitches.

Recovery: The recovery period for LASIK is relatively quick. Patients usually experience improved vision within a day or two after the procedure. Eye drops and follow-up visits are necessary to monitor healing and ensure optimal vision correction.
