Glaucoma Surgery

Surgery involves either laser treatment or making a cut in the eye to reduce the intraocular pressure. The type of surgery your doctor recommends will depend on the type and severity of your glaucoma and the general health of your eye.

Surgery can help lower pressure when medication is not sufficient. However, it cannot reverse vision loss.

Epi-LASIK Eye Surgery: How It Works

Epi-LASIK is a laser vision correction procedure that is very similar to LASIK and LASEK, and may be a good alternative to these procedures for certain eyes.

In epi-LASIK, the flap created on the cornea is thinner than a LASIK flap. This can be an advantage for patients with thinner-than-normal corneas.

The epi-LASIK flap is very similar to the thin flap created in LASEK surgery. In both procedures, the flap contains only cells from the very thin outer layer of the cornea, called the epithelium.

The difference is how the epi-LASIK and LASEK flaps are produced.

A LASEK flap is created with a tool that has a sharp blade. In epi-LASIK, the flap is separated from the underlying corneal layer (the stroma) with an instrument called an epithelial separator that has an oscillating plastic blade that has a thin blunt edge.

And unlike in LASEK, an alcohol solution typically is not applied to the eye in epi-LASIK to loosen epithelial cells from the underlying corneal stroma. Some surgeons prefer epi-LASIK over LASEK for this reason, since alcohol is toxic to epithelial cells and can increase healing time after the procedure.
