Twenty years from now, the use of refractive surgery to treat pediatric conditions will have been shown to be either a great advance, a sometimes useful tool, or a serious mistake for young patients with refractive errors. It falls on ophthalmologists practicing in the early part of the 21st century to determine how to best serve, as well as protect patients while navigating through those years...

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...

AIM To construct patient-specific solid models of human cornea from ocular topographer data, to increase the accuracy of the biomechanical and optical estimate of the changes in refractive power and stress caused by photorefractive keratectomy (PRK). METHOD Corneal elevation maps of five human eyes were taken with a rotating Scheimpflug camera combined with a Placido disk before and after ref...

purpose: to study the distribution of ocular higher-order aberrations (hoas) and mesopic pupil size in individuals screened for refractive surgery. methods: ocular hoas and mesopic pupil size were studied in 2458 eyes of 1240 patients with myopia, simple myopic astigmatism and compound myopic astigmatism and 215 eyes of 110 patients with hyperopia, simple hyperopic astigmatism and compound hype...

BACKGROUND To examine the influence of posterior corneal astigmatism on postoperative refractive astigmatism in pseudophakic eyes after cataract surgery. METHODS The study enrolled 64 pseudophakic eyes of 50 patients (71.8 ± 9.9 years old, mean ± standard deviation) who had undergone phacoemulsification with non-toric IOL implantation. Refractive astigmatism was measured using an auto ref-ker...

There is a long history of corneal refractive surgery. Leonardo Da Vinci in 1508 said the theory of refractive errors. The first systematic analysis of the nature and results of refractive errors came from Francis Cornelius Donders. His classic treatise, “On the anomalies of accommodation and refraction of the eye”, outlined the fundamental principles of physiological optics. Ironically, in thi...

PURPOSE To assess the accuracy of intraocular lens (IOL) power prediction for cataract surgery with open angle glaucoma (OAG) and to identify preoperative angle parameters correlated with postoperative unpredicted refractive errors. MATERIALS AND METHODS This study comprised 45 eyes from 45 OAG subjects and 63 eyes from 63 non-glaucomatous cataract subjects (controls). We investigated differe...

Introduction: Traditional therapy for anisometropic amblyopia often fails when severe anisometropia is present. Recent advances in refractive surgery for anisometropic amblyopia suggest that surgical treatment may be a viable alternative in certain situations. Methods: The potential indications for refractive surgery for anisometropia, the different refractive procedures available, and the risk...
