purpose : to investigate the sensations experienced by chinese patients during refractive surgery including the laser in situ keratomileusis (lasik), epi-lasik, and sub-bowman keratomileusis (sbk) techniques. a prospective, randomized, and self-matched clinical study was conducted. methods : the participants included 44 men and 58 women aged 16 to 47 years old (mean 24.3±0.6 years) who underwen...

purpose: to evaluate the visual outcomes of cross-cylinder ablation in laser in situ keratomileusis (lasik) for eyes with high astigmatic refractive errors and low spherical component. methods: we prospectively evaluated cross cylinder lasik in patients with high astigmatic refractive error but low spherical component over a period of 2 years. all procedures were performed with the nidek ec-500...

purpose : this study was planned to evaluate the efficacy, safety and complication of photorefractive keratectomy (prk) as a retreatment of residual myopia after previous laser in situ keratomileusis (lasik). methods : in this descriptive study in ophthalmology ward, feiz hospital, isfahan university of medical sciences, iran, with the consideration of inclusion and exclusion criteria, 170 eyes...

OBJECTIVE To evaluate the effects of excimer laser in situ keratomileusis in correcting severe myopia and astigmatism after penetrating keratoplasty. METHODS Excimer laser in situ keratomileusis was performed on ten eyes of ten patients to correct high ametropia in cases having previously undergone penetrating keratoplasty. RESULTS After surgery, all grafts remained clear and no corneal gra...

Purpose: To evaluate the safety and reproducibility of using +3 Ring Moria M2 microkeratome (Mechanical Technology) with patients suffering from high K reading. Setting: Eye Care Private Centre-surgery Centre, Jeddah, Saudi Arabia. Methods: Data had been reviewed starting from 2005 up to 2010; with the aim to review and evaluate all the data and complications after using +3 Ring Moria M2 single...

purpose: to evaluate and compare tear secretion and tear film instability following laser in situ keratomileusis (lasik) and laser assisted subepithelial keratectomy (lasek). methods: in a randomized clinical trial, 30 eyes of 15 patients underwent lasik and 30 eyes of 15 patients underwent lasek to correct myopia. tear secretion and tear film instability were tested preoperatively, 2 and 6 wee...

purpose : to describe a case of successful laser in situ keratomileusis (lasik) retreatment over a previous lasik surgery after 11 years case report : the patient had his first lasik for the correction of -2.25 -1.75×90° and -2.25 -1.00×90° in the right and left eye, respectively. eleven years later, the refraction in the right eye was plano -3.25×80° and he was scheduled for an enhancement pro...

purpose: to report occurrence, management, and outcome of late-onset traumatic dislocation of laser in situ keratomileusis (lasik) flaps case report: we report a patient with late-onset lasik corneal flap dislocation after blunt ocular trauma occurring four years after surgery. an ultrasound biomicroscopy (ubm) was performed to view the status of flap and determination of flap thickness. result...

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 assess and to compare stromal and endothelial changes at the cellular level in patients who had photorefractive keratectomy (prk) and laser in situ keratomileusis (lasik) using in vivo confocal microscopy methods : in this semiexperimental study, 32 eyes of 16 patients (4 males and 12 females) with low to moderate myopia [-1.00 to -4.50 diopters (d)] or low to moderate myopic astig...
