Laser in situ keratomileusis (LASIK) is the most commonly performed refractive surgical procedure for the correction of ametropia. The advantages of LASIK include rapid visual rehabilitation, decreased stromal scarring, less irregular astigmatism, minimal regression, less postoperative pain, and the ability to treat a greater range of refractive disorders. Unlike surface-ablation procedures, LA...

Multiple posterior segment complications can occur after LASIK. Posterior vitreous detachment, macular holes, retinal hemorrhages, retinal detachment, and several other complications have been described. A case of posterior vitreous detachment with epiretinal membrane in a young adult after LASIK is reported. LASIK surgeons must be aware of the possibility of posterior segment complications aft...

PURPOSE The aim of the study was to evaluate the safety of besifloxacin ophthalmic suspension 0.6% as antibacterial prophylaxis in the surgical setting. METHODS Two prospective safety surveillance studies were conducted-one in the cataract surgery setting and the other in the laser-assisted in situ keratomileusis (LASIK) surgery setting. Cases from patients aged 18 years and above were eligib...

OBJECTIVE To assess efficacy, safety, predictability, stability, and changes in corneal higher-order aberrations (CHOAs) and contrast sensitivity (CS) after a femtosecond laser for LASIK and standard LASIK for myopia. DESIGN Prospective, randomized, comparative clinical study. PARTICIPANTS Two hundred eyes of 100 consecutive patients who underwent LASIK treatment using the VISX S2 laser sys...

AIM To investigate the influence of laser assisted in situ keratomileusis (LASIK) on the values for retinal nerve fibre layer thickness (RNFLT) as measured with scanning laser polarimetry (SLP) during the healing process of the cornea after LASIK. METHODS SLP with the GDx instrument was performed on 20 consecutive healthy subjects without any eye disease undergoing LASIK for ametropia correct...

PURPOSE To investigate corneal healing and the factor(s) possibly responsible for refractive changes after laser in situ keratomileusis (LASIK). METHODS Twenty eyes of 10 patients who underwent LASIK for myopia were examined clinically and by real-time confocal microscopy for 6 months. Epithelial and posterior stromal thicknesses and the thickness of the keratocyte activation zone were measur...

purpose : to compare the postoperative results of epi-lasik and photorefractive keratectomy-mitomycin (prk-mitomycin) in patients with moderate to high myopia methods : for this double-blind clinical trial, samples were randomly selected among those subjects above 20 years of age who were visited for myopia correction and had a spherical equivalent between -4 to -8 d. we randomly performed prk-...

PURPOSE To investigate if the parameters measured routinely prior to cataract surgery with multifocal intraocular lens (IOL) implantation can predict the necessity of additional laser in situ keratomileusis (LASIK) to improve visual outcome. METHODS Records of patients undergoing cataract surgery between January 2008 and December 2009 were reviewed. Individuals satisfied with visual outcome o...

purpose : to assess the outcomes of laser in situ keratomileusis (lasik) in patients with multiple sclerosis (ms) methods : 15 eyes of 8 patients with ms (2 men and 6 women) who referred for myopia treatment (with or without astigmatism) were undergone lasik. after refractive and visual acuity examinations, topographic and pachymetry screening, intraocular pressure (iop) measurement, biomicrosc...

PURPOSE To compare forward shift of posterior corneal surface and higher-order aberration (HOA) changes after LASIK, LASEK, and wavefront-guided LASEK surgery in moderate myopia METHODS One hundred eighty four eyes undergoing LASIK, LASEK and wavefront-guided LASEK with VISX STAR S4 were included in this study. The posterior corneal elevation was measured with Orbscan before, 2 and 4 months a...
