Vision Correction (LASIK)

What is LASIK

LASIK (which stands for “laser-assisted in situ keratomileusis”) is a safe, reliable, and painless way to improve vision.

LASIK reshapes the cornea so that light traveling through it changes the way light is refracted so that it is properly focused on the retina and objects can be seen clearly.

How LASIK Works

During a LASIK procedure, a device called a microkeratome cuts a thin flap on the surface of the cornea. Patients are given anesthesia so they can’t feel the instruments. The flap is then lifted and a laser beam reshapes the cornea’s curvature to improve vision.

The flap is then closed and covered with a protective contact lens. The entire procedure takes only 15-30 minutes per eye, and LASIK patients are usually ready to leave within an hour or two. The flap heals on its own within a few days with no need for stitches.


Frequently referred to as “bladeless LASIK,” IntraLase® uses a specialized piece of equipment to create a precise flap through which the operation is performed. It can be more time-consuming than traditional LASIK, but your ophthalmologist can help you determine which is the right choice before the procedure.

How IntraLase Surgery Works

The IntraLase FS laser is a highly precise tool that helps in the first step in laser vision correction surgery. During the procedure, the IntraLase laser fires 15,000 pulses per second into the cornea, where the initial opening flap can be created at a depth and diameter determined by the surgeon.

In addition to benefiting from this pinpoint accuracy, patients who undergo surgery conducted with the IntraLase laser are less likely to need a follow-up procedure than with other technologies.

A common complaint after surgery is sensitivity to light, but this subsides quickly. Antibiotic eye drops will be prescribed for a few days, along with any other post-operative instructions. Full recovery takes a few weeks.
