Introducción: La cirugía de cataratas tiene como objetivo restablecer la función visual comprometida por opacificación del cristalino; con el implante Lente Intraocular se pretende obtener mejor agudeza posible sin corrección adicional.

Advances in technology have made surgery in children safer and faster. The management of pediatric cataract has made rapid progress in the past decade with the availability of safer anesthesia, newer technique's, more predictable intraocular lens (IOL) power calculation, a better understanding of neurobiology, genetics, amblyopia management, improved IOL designs for preventing visual axis opaci...

PURPOSE To evaluate the predictability of the refractive correction achieved with a positional accommodating intraocular lenses (IOL) and to develop a potential optimization of it by minimizing the error associated with the keratometric estimation of the corneal power and by developing a predictive formula for the effective lens position (ELP). MATERIALS AND METHODS Clinical data from 25 eyes...

introduction: in cases of poor satisfaction with aphakic glasses and intolerant or reluctant to use contact lenses, secondary intraocular lens (iol) implantation provide an alternative aphakic vision correction. this study aimed to evaluate surgical problems.  intraoperative and postoperative complications and visual acuity outcomes of secondary anterior and posterior chamber intraocular lens i...

Aim: To design an accommodating intraocular lens with extended accommodative range that can be adapted to current standard phacoemulsification and endocapsular implantation technique. Method: Ray tracing analysis and lens design; cadaver eye implantation. Results: Ray tracing analysis indicated that axial movement of an exaggerated converging anterior optic linked by spring loaded haptics to a ...

purpose: to compare aspheric and spherical hydrophilic intraocular lenses (iols) in terms of contrast sensitivity and visual acuity in photopic and mesopic conditions. methods: this triple-blind randomized clinical trial was performed on 40 eyes of 40 patients at al-zahra eye center, zahedan, iran. the eyes were randomized to standard phacoemulsification procedure with spherical (adapt, b&l;) o...
