PURPOSE To compare two different femtosecond lasers used for flap creation during laser-assisted in situ keratomileusis (LASIK) surgery in terms of their effects on the corneal endothelium. METHODS We performed LASIK surgery on 254 eyes of 131 patients using IntraLase FS60 (Abbott Medical Optics, Inc, Irvine, CA; IntraLase group) and 254 eyes of 136 patients using Femto LDV (Ziemer Group AG, ...

PURPOSE To report serious complications caused by recutting laser in situ keratomileusis (LASIK) flaps for enhancement and reconsider the current preferred method of LASIK enhancement. SETTING Multiple surgeon practices. METHODS This retrospective noncomparative nonconsecutive case series comprised LASIK patients in the private practices of 9 experienced refractive surgeons and those report...

Laser in situ keratomileusis (LASIK) is an effective procedure to treat a wide range of myopia. The advantages of LASIK over photorefractive keratectomy (PRK) are rapid visual recovery, lower risk of corneal haze, greater regression of myopia, and less postoperative pain. However, LASIK requires more skillful surgical technique and more instrumentation than PRK. Thus, inaccurate and inadequate ...

PURPOSE To evaluate changes in retinal nerve fiber layer (RNFL) thickness after laser in situ keratomileusis (LASIK) using a scanning laser polarimeter with fixed corneal compensation (GDx) and the retinal thickness analyzer (RTA). METHODS Thirty-eight eyes of 19 healthy subjects (10 female and 9 male; mean age 37.0-/+8.8 years) underwent GDx and RTA measurements before and after LASIK. All s...

PURPOSE To report four cases of corneal interface complications that occurred after excimer laser in situ keratomileusis (LASIK). METHODS Four eyes of three patients underwent technically uneventful LASIK. RESULTS One day after LASIK, patients presented with severe pain, blurred vision, conjunctival infection, and diffuse opacity at the interface. Two days after LASIK, significant features ...

PURPOSE To report on keratoectasia after laser in situ keratomileusis (LASIK) in two eyes of two patients who had no obvious preoperative risk factors, and treatment of keratoectasia by intrastromal corneal ring segments. METHOD Clinical interventional case report. RESULTS Two patients underwent LASIK in both eyes at Shinagawa LASIK center, Tokyo. Preoperative standard ophthalmological exam...

Materials and methods: Prospective analysis of 34 eyes of 17 patients over 40 years of age treated with Allegreto wavefront LASIK system. The study was conducted at MEDEA LASIK Centre, Little Flower hospital, Angamaly. Average patient age was 53.3 years. Pre operative refraction ranged from – 5.75 to + 2.25 diopters(D). Non dominant eyes underwent Presbyopic LASIKan aspheric pupil size dependan...

AIMS To investigate the histopathological changes of rabbit corneas after laser in situ keratomileusis (LASIK) and to evaluate the corneal wound healing process. METHODS A LASIK was performed on white rabbit eyes. Postoperatively, rabbits were killed on days 1 and 7, and at 1, 3, and 9 months. RESULTS Periodic acid Schiff (PAS) positive material and disorganised collagen fibre were seen alo...

PURPOSE To compare the incidence of posterior vitreous detachment (PVD) after femtosecond and microkeratome laser in situ keratomileusis (LASIK). SETTING Rowad Correction Centre, Cairo, Egypt (a private center affiliated to Cairo University). DESIGN Prospective, nonrandomized comparative unmasked study. METHODS The study was conducted at a single laser center. Eligible patients chose betw...

PURPOSE To assess the intraocular pressure (IOP) and ocular rigidity (E) at 1, 3, 6 and 24 postoperative months in eyes that underwent LASIK. METHODS The IOP measured by Goldmann applanation tonometer (GAT) and by the 5.5 and 10 gm. weights of a standardized Schioetz tonometer (ST) and the E measured by differential tonometry (the 5.5 and 10 gm. of ST) were assessed before and after LASIK (at...
