OBJECTIVE To evaluate the characteristics of strabismus in infants who underwent cataract surgery with and without intraocular lens (IOL) implantation. DESIGN Secondary outcome analysis in a prospective, randomized clinical trial. PARTICIPANTS The Infant Aphakia Treatment Study is a randomized, multicenter (n = 12), clinical trial comparing treatment of aphakia with a primary IOL or contact...

PURPOSE To present a bi-sign aspheric intraocular lens (IOL) and make theoretical comparisons with spherical and one-sign aspheric IOLs for retinal image quality in mesopic conditions and intermediate image capability in photopic conditions. METHODS Using ray-tracing in pseudophakic eye models, retinal image quality in terms of modulation transfer function was analyzed between the bi-sign asp...

PURPOSE To compare surgical results between conventional intraocular lens (IOL) implantation using an ophthalmic viscosurgical device (OVD) and IOL implantation using a balanced salt solution (BSS) after irrigation/aspiration (I/A) of the lens cortex. METHODS A randomized prospective study was conducted on 62 patients who underwent cataract surgery. Following completion of conventional I/A of...

PURPOSE To examine lateral and axial positioning of phakic intraocular lenses (IOLs) with iris fixation in the anterior chamber and to examine short-term stability of the IOL position. SETTING The Netherlands Opthalmic Research Institute, Amsterdam, the Netherlands. METHODS Thirty patients participated in the study. Thirty-one eyes were implanted with the 204 type myopia IOL, 14 eyes with t...

Endothelial keratoplasty (EK) is the most exciting recent development in corneal transplantation. It has experienced surprisingly rapid growth in a very short period of time. One of the indications for EK is pseudophakic bullous keratopathy. However, concomitant intraocular lens (IOL) exchange, if indicated, may prove challenging. Some surgeons routinely perform IOL exchange with a scleral-fixa...

M anagement of astigmatism at the time of cataract or refractive lens surgery has evolved to include arcuate keratotomy and toric intraocular lens (IOL) implantation. Integration of preoperative corneal diagnostic instrumentation via Streamline digital wireless connectivity to the LENSARTM femtosecond laser (LENSAR Inc., Orlando, FL, US) now allows improved precision and accuracy of arcuate inc...

The implantation of a phakic intraocular lens (IOL) for the correction of moderate or high myopia has theoretical advantages in comparison with corneal procedures and clear lens extraction, such as precision and stability not dependent on the corneal healing process, a wider range of correction, magnification of the intraocular image, and preservation of accommodation. However, these lenses hav...

A 64-year-old diabetic lady underwent pars plana vitrectomy in her left eye for a taut posterior hyaloid face due to proliferative diabetic retinopathy (PDR). Visual acuity (VA) at baseline had been 20/120. She had previously received panretinal laser photocoagulation (PRP) and the retinopathy had been stable, but there was localized extrafoveal tractional retinal detachment in the inferonasal ...

Intraocular lens (IOL) is an artificial lens implanted into the eye. It usually replaces the existing crystalline lens, which is clouded over due to a cataract. In order to evaluate the optical performance of different IOLs an optomechanical model of human eye was developed. This model closely reproduces anatomical and optical properties of the average human eye. This makes it possible to measu...

The aim of this study was to evaluate clinical outcomes after toric intraocular lens implantation for astigmatism correction in patients undergoing cataract surgery. This prospective observational study included eyes undergoing cataract surgery at Sestre milosrdnice University Hospital Center between February and September 2011. The study enrolled eyes that had visually significant cataract and...
