PURPOSE To evaluate the efficacy, predictability, stability, safety, and complications of secondary anterior iris fixation of the Artisan iris-fixated intraocular lens (IOL) to correct aphakia in eyes without sufficient capsule support. SETTING Department of Ophthalmology, Jinling Hospital, School of Medicine, Nanjing University, Nanjing, China. DESIGN Cohort study. METHODS Eyes having im...

OBJECTIVE Determine the effects of display viewing distance on both the visual and musculoskeletal systems while the text height is held constant across viewing distances. BACKGROUND The distance from the eyes to a computer display may affect visual and neck comfort. If the angular size of the characters remains the same, it is recommended that the display be placed at a farther viewing dista...

BACKGROUND/AIMS To evaluate the visual performance of patients with successful macular hole surgery with a minimum follow-up of 3 years. Results were compared with the performance of the healthy fellow eyes. METHODS 15 patients were studied. The healthy fellow eyes of the patients (13 eyes) served as a control group. Age, gender and best-corrected logMAR visual acuity were recorded. Reading a...

Aim To evaluate the configuration of the anterior chamber angle quantitatively and study the morphological changes in the eye with ultrasound biomicroscopy (UBM) in primary angle closure glaucoma (PACG) patients after laser peripheral iridotomy (LPI). Materials and methods A total of 185 eyes of 185 PACG patients post-LPI and 126 eyes of 126 normal subjects were included in this prospective s...

PURPOSE The main aim of this study was to compare the efficacy, safety, and predictability of femtosecond laser-assisted in situ keratomileusis performed by two different laser suites in the treatment of myopia for up to 6 months. METHODS In this two-site retrospective nonrandomized study, myopic eyes that underwent laser-assisted in situ keratomileusis using IntraLase FS 60 kHz formed group ...

introduction: dacryocystorhinostomy (dcr), a popular surgical procedure, has been performed using an endoscopic approach over recent years. excellent anatomical knowledge is required for this endoscopic surgical approach. this study was performed in order to better evaluate the anatomical features of the lacrimal apparatus from cadavers in the isfahan forensic center as a sample of the iranian ...

Earlier experiments suggest that the perception of relative and absolute distance in binocular space is affected by the convergence angle to the stimulus. The question is how? A hypothesis was proposed in which the obtained effects are accounted for in terms of convergence differences. The hypothesis states that binocular stimuli are related to the rest convergence of the eyes which is assumed ...
