A laser ablates the corneal stroma and a hinged flap is created with a keratome.

Has become treatment of choice for many patients with refractory errors such as myopia, hyperopia,and astigmatism.

About 750,000 procedures annually.

95.4% of patients satisfied with results of the procedure.

Complication includes flap dislocation injury.

It reshaped the cornea.

The procedure flattens the cornea by removing tissue from the central cornea.

If a patient is farsighted the cornea is made steeper by removing tissue from the peripheral cornea.

With astigmatism it reshapes the cornea into a more symmetrical, spherical shape.

Presbyopia not be reversed with Lasik.

In the initial 24 hours after surgery, flap dislocation can occur as a result of mechanical disruption.

The process takes less than 15 minutes, does not require general anesthesia, stitches, or bandaging.

Flat dislocation is uncommon, but may be encountered even years after procedure.

Complications are in common and include eye infections and inflammation.

Some patients experience dryness, light sensitivity, halos, and glare, but these are usually temporary problems.

Dry Eye Syndrome is a common complication after LASIK surgery, with symptoms including discomfort, burning, and blurred vision.

Flap complications can occur during or after surgery and can lead to irregular astigmatism and visual distortions.

The flap created during LASIK can sometimes be too thin, too thick, or uneven, which can affect the outcome of the surgery.

Epithelial ingrowth occurs when cells from the cornea’s surface layer grow under the flap after surgery.

Diffuse lamellar keratitis (DLK) is an inflammatory condition that can cause blurred vision and discomfort: usually treated with topical steroids.

Corneal ectasia is a rare but serious complication where the cornea thins and bulges outward, causing distorted vision.

It is more likely to occur in patients with pre-existing weak corneas.

Rarely, infections can occur after LASIK surgery.

Corneal perforation is an extremely rare complication that can occur if the laser accidentally cuts too deeply into the cornea.

A rare but serious complication is the Loss of Best-Corrected Visual Acuity (BCVA):

While all these complications can occur, they are relatively rare and most patients have successful outcomes with LASIK surgery.

Within 95% of patients are satisfied with the outcome of the surgery.
