LASEK Eye Surgery ? How LASEK Works, and What To Expect ? AllAboutVision com.LASEK, or E-LASIK, is better for some patients than regular LASIK.Learn when LASEK is the right laser eye surgery choice.Tweet Lasek Eye Surgery laser epithelial keratomileusis is a newer variation of.PRK , a procedure in which laser energy is applied directly to the eye?s outer surface for reshaping and vision correction.To understand how Lasek Eye Surgery works, you first must know the fundamental differences between.With LASIK , a thin flap is cut into the eye?s surface and then lifted.Laser energy is applied to the eye for reshaping, and the flap is replaced to serve as a type of natural bandage for quicker healing.An eye surgeon using PRK does not cut a thin flap into the eye?s surface, as occurs with LASIK.Instead, laser energy is applied directly to the eye?s surface.The ultra thin, outer layer of the eye epithelium is removed completely by laser energy during a PRK procedure, and eventually grows back.A Lasek Eye Surgery procedure involves preserving the extremely thin epithelial layer by lifting it from the eye?s surface before laser energy is applied for reshaping.
After the Lasek Eye Surgery procedure, the epithelium is replaced on the eye?s surface.With Lasek Eye Surgery, the ultra thin flap is created with a special cutting tool known as a trephine.Lasek Eye Surgery is used mostly for people with corneas that are too thin or too steep for LASIK, when it may be difficult to create a thicker LASIK flap.Lasek Eye Surgery was developed to reduce the chance of complications that occur when the flap created during LASIK does not have the ideal thickness or diameter.Epi-LASIK uses a plastic blade, called an epithelial separator, to detach part of the epithelial layer from the eye.However, eyes undergoing Lasek Eye Surgery procedures generally heal more slowly and result in more complaints of discomfort than with LASIK.For this reason, some surgeons prefer to perform PRK rather than Lasek Eye Surgery or epi-Lasek Eye Surgery because they find no advantage in the latter procedures.Journal of Refractive Surgery indicated that people undergoing PRK tended to have less pain and healed slightly faster than people who had undergone a surgical technique called butterfly Lasek Eye Surgery ?Butterfly? refers to the shape and type of thin flap lifted in Lasek Eye Surgery, which is thought to increase comfort and healing time. The Lasek Eye Surgery Procedure During Lasek Eye Surgery, your surgeon uses local anesthesia.After sponging the alcohol solution from the eye, the surgeon uses a tiny hoe to lift the edge of the epithelial flap and gently fold it back out of the way.Afterward, a type of spatula is used to place the epithelial flap back on the eye.
In a new variation of Lasek Eye Surgery, the same plastic blade epithelial separator used in epi-LASIK creates the thin epithelial flap.But because alcohol is applied during the procedure as it is in straight Lasek Eye Surgery, the procedure is called epi-Lasek Eye Surgery with an ?E? instead of an ?I ?.After Lasek Eye Surgery In many ways, Lasek Eye Surgery vision recovery is slower than LASIK recovery, but there are some differences.According to doctors who perform Lasek Eye Surgery, the flap edge heals in about a day, though patients usually wear a bandage contact lens for approximately four days to protect the eye.Your eye may feel irritated during the first day or two afterward.You also may experience more pain with Lasek Eye Surgery compared with LASIK.Talking to Your Doctor If you are considering LASIK, but your doctor says you need Lasek Eye Surgery, ask why.LASIK Eye Surgery Risks, Advantages, Disadvantages, Facts, History and Complications on MedicineNet com.Get information about LASIK, refractive surgery for vision correction of astigmatism, nearsightedness, farsightedness , risk factors dry eyes, high myopia or hyperopia and benefits.
