Disk halo size measured in individuals with monofocal versus diffractive multifocal intraocular lenses.

Purpose: To compare disk halo size in response to a glare source in eyes with an aspheric apodized diffractive multifocal intraocular lens (IOL) or aspheric monofocal IOL.

Setting: Rementeria Ophthalmological Clinic, Madrid, Spain.

Design: Prospective randomized masked study.

[Macular thickness measured by optical coherence tomography in pseudoaphakic eyes with clear vs yellow implant].

Objective: To study the use of optical coherence tomography (OCT), for measuring the macular thickness variations produced over time in elderly pseudophakic subjects implanted with a clear intraocular lens (IOL) in one eye, and a yellow IOL in the other eye.

Methods: Macular thickness measurements were obtained in the 36 eyes of 18 subjects over 65 years, with cataracts surgically removed from both eyes and implanted with different absorbance (clear and yellow) IOLs in 2 separate surgeries. Stratus-OCT was used to determine the macular thickness in 2 sessions with 5 years of difference.

[Reliability of retinal imaging screening in retinopathy of prematurity].

Introduction: The retinopathy of prematurity (ROP) is a potentially avoidable cause of blindness in children. The advances in neonatal care make the survival of extremely premature infants, who show a greater incidence of the disease, possible. The aim of the study is to evaluate the reliability of ROP screening using retinography imaging with the RetCam 3 wide-angle camera and also study the variability of ROP diagnosis depending on the evaluator.

Pseudoaccommodating intraocular lens implantation in patients with irregular nonreactive pupils.

We report 3 patients implanted with the AcrySof ReSTOR pseudoaccommodating intraocular lens (IOL) who had irregular nonreactive pupils as a consequence of pupil stretching during phacoemulsification. Despite the pupils, the visual acuity at distance and near was not compromised. The outcome in these cases suggests that an irregular nonreactive pupil is not an exclusion criterion for pseudoaccommodating IOL implantation.
