Variant LASIK Procedures

Variant LASIK Procedures

Serving Los Angeles, California and Surrounding Communities

There is more than one way to perform LASIK eye surgery. Many different variants of the LASIK procedure exist, each one designed to address different concerns and candidates. In order to understand the variant LASIK procedures, it’s important to first understand how the main LASIK surgery works.

LASIK is performed by mapping the unique irregularities of your eyes (usually through Wavefront Diagnosis) and programming this information into a femtosecond laser. A flap is then created in the top layer of your cornea and peeled back so the laser treatment can be applied directly to your eye. The laser re-shapes your cornea to allow light to focus correctly for the first time.

What is LASEK?

LASEK is nearly identical to LASIK except for one major difference: the thickness of the corneal flap that is created. In LASIK, the flap includes tissue from both the epithelial (top) layer, and the stroma layer of your cornea. In contrast, the LASEK flap only includes tissue from the epithelial layer of your cornea.

LASEK is the ideal refractive surgery option for people who are not good LASIK candidates due to overly thin corneas. The recovery time tends to be a couple of days longer than LASIK, but it is still relatively short: about 4-7 days on average.


SUPERLASIK (also called Epi-LASIK) is a newer type of LASIK procedure that was first developed as a solution to some of the potential issues with LASIK and LASEK. You can think of SUPERLASIK as a cross between LASIK and LASEK, but it differs from them both in a few key areas.

Like LASEK, SUPERLASIK involves cutting only into the cornea’s outer layer – the epithelium. However, a different type of blade is used in SUPERLASIK. Dr. Khanna uses an epikeratome to create an extraordinarily thin epithelial flap during SUPERLASIK – even thinner than is possible with IntraLase.

A major benefit of SUPERLASIK is that it allows patients with thin or abnormal corneas to benefit from laser vision correction, even though these same patients may not be candidates for LASIK. Your recovery is fast, just like LASIK, and can also aid patients who suffer from dry eye syndrome.
