Abstract
Refractive Surgery of Myopia performed by LASIK , Z-LASIK , PRK , Phaco and I.C.L. on 52 patients including 20 patients for LASIK surgery, also 20 patients for Z-LASIK, 8 patients for PRK, 3 patients for PHACO surgery and 1 patients for I.C.L., this type of surgery is used for vision correction because it is quick and painless. The patient’s vision was examined before and after the surgery by using Snellen chart to determined visual acuity; the corneal thickness, shape of cornea were determined by Topography; the refractive error was measured before and after surgery by using Auto refractor meter, also determine gender, age and degree of glasses for each patient. The refractive surgery of myopia was performed in order to discard the use of glasses. Patients after the 18 years were eligible for surgery using LASIK, Z-LASIK, PRK except PHACO and I.C.L techniques. The processes of PRK, Z-LASIK works with little thickness of cornea of 480 microns. High degrees of short sightedness were corrected by PHACO surgery due to the thickness of the cornea which could not tolerate scrape to perform the surgery for all grades. I.C.L. can be used better on young patients because after surgery, there is no need to glasses compared with LASIK,PHACO and Z-LASIK surgery may require glasses after surgery , this surgery undesirable for young. Surgery using PRK technique until 4 degrees of short sight safely while works LASIK surgery with more than 4- degrees occurs with LASIK surgery. Z-LASIK works only with high degree of myopia with a little cornea thickness of 480 microns, either with very low degrees of myopia with a cornea thickness of 500 microns or more works Z-LASIK and LASIK both.
