LASEK is an alternative way of performing LASIK for people who do not qualify for the original procedure. LASEK stands for Laser Epithelial Keratomileusis. It’s also called e-LASIK (epithelial LASIK). If you have been told that your corneas are too thin, too flat, or too steep for LASIK, you may be an excellent candidate for LASEK.
Lasek procedure is performed by removing an ultra thin layer of the cornea. Done by a chemical compound which disintegrates a thin layer of the cornea allowing the laser to be performed on top of the cornea. Dr. Khanna intact uses a specially formulated solution to weaken the cell connections. The solution is left on for about 30 seconds. Then the Lasek surgeon gently lifts the loosened flap tissue.
Afterwards, a bandage contact lens is used to protect the treated area while it heals. This takes between three and ten days, depending on how large an area was treated and your individual healing rate.
Traditional LASIK eye surgery is an excellent vision correction option for a wide variety of people, but it may not be right for everyone. Thankfully, since LASIK was first approved by the FDA, ophthalmologists have devised more ways of performing this innovative procedure, increasing the pool of candidates.
The reason why some people may not qualify for LASIK is usually centered around problems with the corneal flap. This flap is created at the beginning of a traditional LASIK procedure, and involves removing surface cells to expose the next layer down: the stroma. The laser then removes small pieces of stromal tissue to reshape the cornea before the flap is replaced for healing.
In traditional LASIK, problems can occur if:
Superlasik means superficial lasik. A special automated instrument is used to fashion an epithelial flap. This is called an epikeratome. There is no use of chemicals. The damage to cells is less. In essence superlasik is a more advanced and superior procedure.
Lasek can still be performed when superlasik is contraindicated. Situations like post radial keratotomy, after previous lasik eye surgery are some examples. Further if we need to avoid pressure on the base of retina, Lasek is the preferred choice.
PRK uses a mechanical method to remove the top layer. It can be a spatula. Some surgeons prefer a electric brush. These methods are less accurate. They can also injure the stroma. The trauma from the mechanical rubbing can release mediators of inflammation, PRK therefore gives more pain. There is increased chances of corneal haze and scarring.
