PURPOSE To report national case-finding results for nontuberculous mycobacterial keratitis and describe its association with laser in situ keratomileusis (LASIK). DESIGN Enhanced passive disease reporting. METHODS In April 2001, we investigated a California cluster of Mycobacterium chelonae keratitis associated with hyperopic LASIK using a contact lens mask. To identify other possibly relat...

PURPOSE To evaluate the trends in corneal refractive procedure selection for the correction of myopia, focusing on the relative proportions of laser in situ keratomileusis (LASIK) and surface ablation procedures. METHODS Only eyes that underwent LASIK or surface ablation for the correction of myopia between 2008-2011 were included in this retrospective study. Additional recorded parameters in...

Purpose. To assess the incidence of central serous chorioretinopathy (CSCR) following laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK). Methods. A chart review was performed to identify all patients with CSCR and a previous history of LASIK or PRK. Results. Over the 6-year study period, 1 of 4,876 eyes which had LASIK or PRK at the Moran Eye Center was diagnosed with C...

BACKGROUND A European web-based registry for refractive surgery was established in 2008; The European Registry of Quality Outcomes for Cataract and Refractive Surgery (EUREQUO). The aim of the registry was to improve treatment and standards of care for refractive surgery. Further aims were to offer a tool for benchmarking by establishing a reference database and for surgeons to enter and analyz...

The case illustrates the use of a light-adjustable intraocular lens (IOL) in a patient who had had refractive surgery and developed blunt trauma with resultant flap damage and traumatic cataract. Consistent with early reports of the light adjustable IOL, which show positive results in non-LASIK eyes, this case suggests that the light-adjustable IOL may have similar benefits in the post-LASIK ey...

The primary goal of refractive surgery is the smallest residual refractive error and preserved contrast sensitivity with the same visual capacity under bright and dim illumination. Corneal refractive surgery cannot correct very high ametopias; from -10 to -14 D is the limit of myopia correction in the cornea and from +4 to +6 D, the limit of hyperopia correction. Intraocular refractive surgery ...

PURPOSE To evaluate with the use of corneal topographic data the differences between total corneal power calculated using ray tracing (TCP) and the Gaussian formula (GEP) in normal eyes, eyes that previously underwent laser in situ keratomileusis/photorefractive keratectomy (LASIK/PRK), and theoretical models. METHODS TCP and GEP using mean instantaneous curvature were calculated over the cen...

PURPOSE: To evaluate the safety and efficacy of laser in situ keratomileusis (LASIK) compared to photorefractive keratectomy (PRK) for the correction of low or moderate myopia (-0.50 to-6.00 D) at 6 months after surgery. refractive outcomes of LASIK and PRK were similar. Although flap related complications occurred only after LASIK, the overall risk of loss of best spectacle-corrected visual ac...
