What is Epi-Lasik eye surgery? Cons & Pros
Epi-Lasik, also known as Epi-K or Advanced Surface Treatment. It actually
combines advantages from both PRK and traditional Lasik into one single
procedure.
Epi-Lasik is similar to Lasek, In Lasek, the epithelium is cut with a
cylinder-shaped blade called a trephine and is briefly covered with an alcohol
solution to loosen it from the underlying corneal tissue. During the Epi-Lasik
procedure, a blunt microkeratome smoothly removes without cutting the surface
layer, or epithelium, from the cornea.
The next step involves using an excimer
laser just like with conventional Lasik. Afterward, the epithelial flap is
placed back on the surface of the cornea with a spatula. No use of alcohol is
needed to soften or loosen the epithelial cells. Epi-Lasik avoids complications
associated with the deep stromal flaps of ordinary LASIK including flap
irregularity, epithelial ingrowth and corneal ectasia.
Good candidates for Epi-Lasik surgery
Epi-LASIK surgery is not suitable for everyone although it may be considered a
better option should you not be suitable for LASIK surgery. It is ideal for
patients whose corneas may be too thin to safely perform LASIK on. Or those
patients who would like to have laser vision correction but are afraid to have
any type of incision made on their eyes such as boxers, football players and
athletes.
Advantages of Epi-Lasik surgery
Able to treat patients with thinner corneas
Reduced incidence of flap complications
Lower rate of dry eye syndrome
