How does Epi-LASIK differ from LASIK PRK and LASEK?

It may sound very similar to LASEK and is a very similar procedure to this and LASIK. The difference is in the initial stage of the procedure – the part where the outer layer of the cornea, called the epithelium has to be removed so that the laser can do its work.

With Epi-LASEK, the surgeon uses a plastic oscillating blade – called an epikeratome to access the epithelium.

With LASIK the surgeon makes a small incision in the epithelium using a microkeratome (blade).

LASEK involves the surgeon using a small tool or trephine to make an incision in the epithelium. 

The rest of the procedure is the same across all of these.
