OBJECTIVE To evaluate the static and dynamic contrast sensitivity changes in myopic patients before and after laser in situ keratomileusis (LASIK). METHODS Seventy-three eyes in 37 patients with myopia (with or without astigmatism) who received LASIK were tested for static and dynamic contrast sensitivities using the METRO VISION MON ELEC I system at 0.7, 1.4, 2.7, 5.5, 11, and 22 cpd and cps...

To determine whether manifest refractive astigmatism (RA) or anterior corneal (CA) is the best value for excimer laser programming in cases of ocular residual (ORA). Patients who had undergone LASIK surgery with a disagreement between and cylinder (ocular ORA) > 0.75 D were included retrospectively this study. We calculated target induced vector (TIA), surgically (SIA), difference correction pr...

PURPOSE To compare the visual and refractive outcomes after laser-assisted in situ keratomileusis (LASIK) surgery for correction of myopia or myopic astigmatism using a six-dimensional Amaris excimer laser. METHODS In this retrospective cohort study, we enrolled 47 eyes of 28 patients (age: 19-36 years) with myopia or myopic astigmatism. We used the Custom Ablation Manager protocol and perfor...

the objective of the present study was to compare single segment and double segment intacs rings in the treatment of post-lasik ectasia. in this interventional study, 26 eyes with post-lasik ectasia were assessed. ectasia was defined as progressive myopia regardless of astigmatism, along with topographic evidence of inferior steepening of the cornea after lasik. we excluded those with a history...

PURPOSE To describe our clinical experience in wavefront-guided LASIK enhancements using the WaveLight ALLEGRETTO system (WaveLight Technologie AG, Erlangen, Germany) for symptomatic eyes previously treated with standard LASIK. METHODS Twenty-six eyes of 20 patients with residual myopia, hyperopia, or mixed astigmatism and/or night vision symptoms after primary standard LASIK were considered ...

purpose: to determine the efficacy, safety, and stability of these techniques and some factors affecting refractive and visual outcomes in treated patients. methods: 236 lasik-treated eyes (122 patients) and 218 prk-treated eyes (112 patients) with myopia and myopic-astigmatism between -1.25 and -4 diopters (d) underwent refractive surgery over an 11 month period by a single surgeon. patients w...

PURPOSE To evaluate the clinical results of epi-LASIK for the treatment of low to moderate myopia and myopic astigmatism. DESIGN Retrospective, noncomparative, interventional case series. PARTICIPANTS Two hundred thirty-four eyes of 138 patients underwent epi-LASIK for the correction of low to moderate myopia. Mean preoperative spherical equivalent ranged from -1.0 to -7.25 diopters (D) (-3...

The purpose of our study was to evaluate the safety, effectiveness, predictability, and stability myopic astigmatic laser-assisted in situ keratomileusis (LASIK) with simultaneous prophylactic corneal cross-linking (CXL) thin corneas. In total, 100 eyes from 50 patients who were subjected astigmatism femtosecond LASIK CXL included. design retrospective, longitudinal, observational. All had a 48...

PURPOSE To report a successful case management of a retinal tear post-Laser in situ Keratomileusis (LASIK) and retreatment. RESULTS A patient with the history of ocular trauma underwent LASIK procedure for myopic astigmatism. Three months post-LASIK, she received additional excimer laser treatment for a symptomatic persistent central island. One month later; the patient experienced a flap tea...

BACKGROUND To compare changes in higher-order aberrations (HOAs) following small incision lenticule extraction (SMILE) and wavefront-guided femtosecond laser-assisted in situ keratomileusis (WFG FS-LASIK), and to investigate correlations between preoperative spherical equivalence (SE) and components of HOAs affecting visual quality. METHODS Sixty-five myopic eyes from 38 patients were enrolle...
