What is LASIK Surgery?

General overview of the LASIK procedure

• Pre-surgery Evaluation: Before LASIK surgery, a comprehensive eye examination is conducted to determine the patient's candidacy for the surgery. Factors such as corneal thickness, refractive errors, and overall eye health are assessed.

• Corneal Flap Creation: During the LASIK procedure, a specialized laser  (either a microkeratome or a femtosecond laser), is used to create a thin flap on the cornea. This flap is gently lifted to expose the underlying corneal tissue.

• Reshaping the Cornea: The excimer laser is then used to precisely remove a specific amount of corneal tissue, reshaping it to correct the refractive error. In the case of myopia, the laser flattens the cornea, while for hyperopia, it steepens it. Astigmatism can be corrected by smoothing an irregular cornea into a more regular shape.

• Flap Repositioning: After the cornea is reshaped, the surgeon carefully repositions the corneal flap. The flap adheres naturally without the need for stitches.

• Recovery: Most patients experience improved vision shortly after the procedure, although it takes a few days to weeks for optimal results. Patients are usually advised to rest and avoid activities that could irritate the eyes during the initial recovery period.
  

Advantages of LASIK

• The primary benefit of LASIK is the significant improvement in vision. Many people experience reduced dependence on glasses or contact lenses after surgery.
• LASIK often provides quick results, with many patients experiencing improved vision within a day or two after the procedure.
• LASIK has a high success rate, and the outcomes are generally predictable. Most individuals achieve their desired level of vision correction.
• The results of LASIK are generally permanent. While age-related changes may still affect vision later in life, the effects of the surgery remain.
• LASIK is typically a painless procedure. Local anesthetic eye drops are used to numb the eyes during the surgery.
• Many individuals have significantly reduced or eliminated the need for glasses or contact lenses for everyday activities.
• LASIK is known for its quick and relatively painless nature. It is essential to follow post-operative care instructions provided by the laser surgeon to ensure proper healing and optimal results.
