Background: Cataract refractive errors are caused by cataracts. It can go up to several dioptres (D). Correction of expected during cataract surgery altering the axial length measurement. Determine effect posterior sub-capsular cataracts on eye's status. Methods: 112 patients with participated in study. The most common error found PSC was astigmatism, followed myopia. study conducted at Angel E...

PURPOSE To evaluate the effect of non-keratometric ocular astigmatisms on visual and refractive outcomes after photorefractive keratectomy (PRK) for correction of myopic astigmatisms. METHODS Seventy one eyes of 36 subjects were enrolled in this study. Patients underwent PRK for treatment of myopia. Subjects were evaluated for refractive error, keratometry, and visual acuity before and six mo...

PURPOSE To determine changes in stereoacuity in anisometropic myopic eyes after photorefractive keratectomy (PRK). METHODS Myopic patients with at least 1 diopter (D) of anisometropia in sphere, astigmatism, or spherical equivalent who were referred to our hospital for excimer refractive surgery were enrolled as a prospective sequential interventional case series. All patients underwent wavef...

PURPOSE The evaluation of the safety, efficacy, and long-term stability of LASIK procedures utilizing novel platform comprising a femtosecond and excimer laser and multiple networked diagnostics. SETTING Private clinical ophthalmology practice. PATIENTS AND METHODS In consecutive cases of myopic LASIK procedure with a novel refractive platform (FS200 Femtosecond and EX500 Excimer Laser), 19...

PURPOSE We investigated longitudinally the refraction development in children with regressed retinopathy of prematurity (ROP), including those with and those without a history of peripheral retinal laser photocoagulation. METHODS Longitudinal (0-7 years) cycloplegic refraction data were collected prospectively for two groups of preterm children: severe ROP group included those with regressed ...

Animal studies show that the rate of recovery from experimentally induced refractive errors is related to the level of ametropia induced. The present study examined the rate of emmetropisation occurring in a sample of 22 human infants refracted by near retinoscopy during the first six months of life and then again between 12 and 17 months old. None of the subjects were myopic. Regression analys...

PURPOSE To describe and evaluate a new multiple regression-derived nomogram for myopic wavefront laser in situ keratomileusis (LASIK). SETTING Moorfields Eye Hospital, London, United Kingdom. DESIGN Prospective comparative case series. METHODS Multiple regression modeling was used to derive a simplified formula for adjusting attempted spherical correction in myopic LASIK. An adaptation of...

are ours), which is scientifically more important, and which should be the splendid function of the family physician, is ignored. Dr. Gould contributes but little towards the attainment of this lofty aim. He plunges at once into a " medical description of past lives," choosing for his examples De Quincey, Carlyle, Darwin, Huxley and Browning. At first sight the choice seems to be an unfortunate...
