PURPOSE To present the prospective application of the Orbscan II central 2-mm total-mean corneal power obtained by quantitative area topography in intraocular lens (IOL) calculation after refractive surgery. METHODS Calculated and achieved refraction and the difference between them were studied in 77 eyes of 61 patients with previous radial keratotomy (RK), RK and additional surgeries, myopic...

Background: The most common refractive surgical surgery for the treatment of myopia, hyperopia, and astigmatism is laser assisted in situ keratomileusis (LASIK). A very important step LASIK formation flap. corneal flap was made using a variety microkeratomes. purpose this study to compare central thickness following flap.Methods: This retrospective comparative performed on 200 eyeballs divided ...

The purpose of this study is to describe the 26-year-old patient with developed macular hole after bilateral laser in situ keratomileusis (LASIK). A macular hole with sharp margins and irregular surface of surrounding retina appeared in the left eye of the female 26-year-old patient two months after LASIK for correction of myopia (followup of 6 months). Although the best corrected visual acuity...

PURPOSE To identify factors that can lead to corneal ectasia after laser in situ keratomileusis (LASIK). SETTING University refractive surgery center. METHODS In this retrospective study, the charts of all patients (2873 eyes) who had LASIK between May 1995 and November 1999 were reviewed. Fourteen patients (19 eyes, 0.66%) developed post-LASIK ectasia. The mean follow-up was 16.32 months (...

purpose: to evaluate the prevalence, natural course, and final visual acuity in patients with stages iii or iv of diffuse lamellar keratitis (dlk) following laser in situ keratomileusis  (lasik). methods: in this descriptive study, records of all the patients who underwent lasik surgery in two private excimer laser clinics were reviewed. according to linebarger- lindstrom-hardten classification...

AIM To study the posterior corneal topographic changes in eyes with partial flaps during laser assisted in situ keratomileusis (LASIK). METHODS Case records of 16 patients, who had partial flap in one eye during LASIK (group 1) and uncomplicated surgery in the other eye (group 2), were studied. Following occurrence of partial flap intraoperatively, laser ablation was abandoned in all the eyes...

BACKGROUND Refractive stability is influenced by alterations in corneal curvature and corneal thickness after laser in situ keratomileusis (LASIK). The aim of this study was to analyze the changes of central corneal thickness (CCT) and refractive error following thin-flap LASIK surgery in Chinese eyes. METHODS One hundred and fifty-eight myopic patients (302 eyes) who underwent thin-flap LASI...

PURPOSE: To better define the effect of laser in situ keratomileusis (LASIK) on myopic eyes and the risk and incidence of retinal complications after surgery.METHODS: In a prospective study, 200 eyes of 100 patients, 49 male and 51 female, with a mean age of 29.7 years, had a complete posterior pole examination before and at 1 week, 1, 3 and 12 months after bilateral simultaneous LASIK for the ...

purpose: to evaluate the results of laser in situ keratomileusis (lasik) retreatment in  patients with postoperative regression. methods: in a retrospective interventional case series, 153 eyes of 113 patients who had undergone lasik retreatment for postoperative regression were evaluated. both initial lasik and retreatment were performed with a nidek: ec 5000 excimer laser, and flap was made w...
