Laser Epithelial Keratomileusis (LASEK) is a simple technique based on the detachment of the epithelial flap by an alcohol solution prior to the application of laser energy, which resculpts the cornea. This hybrid procedure is an advanced form of PRK. With the dilute solution of alcohol and a lifting motion with a surgical spatula, the epithelial flap is gently detached, gathered and folded away from the laser ablation area.
At this point the treatment procedes as a traditional PRK. At the conclusion, the epithelial flap is repositioned over the cornea. The advantages of LASEK are that it may reduce post-surgical discomfort, lead to faster visual rehabilitation and reduce the incidence of corneal haze.
Astigmatic Keratotomy (AK) is where one or two linear or arcuate incisions are made in the cornea to reduce or eliminate astigmatism. AK can be combined with other procedures (i.e., PRK or LASIK).
Conductive Keratoplasty (CK) involves the use of radio frequency energy applied to the cornea in a specific pattern to correct between .75 and 3.00 diopters of hyperopia (farsightednes). CK was approved by the FDA for the treatment of hyperopia in April 2002.
Edward E. Manche, M.D., then an FDA clinical investigator, performed the first CK procedure in the United States.
Intraocular Contact Lens (ICL) is a procedure where a permanent lens is placed into the eye to reduce and/or eliminate extreme levels of nearsightedness and farsightedness.
