PURPOSE To quantify and compare the in vitro adherence of Staphylococcus epidermidis and Pseudomonas alcaligenes to different intraocular lenses (IOLs). METHODS Fourteen intraocular lenses were used in the experiment. Four of polymethylmethacrylate (PMMA), four of silicone, four of hydrogel and two of acrylic. Eight intraocular lenses were placed in eight test tubes containing 4 ml of Pseudom...

We report the refractive correction of high myopia in a 23-year-old patient with idiopathic microspherophakia using iris-fixated phakic intraocular lenses (pIOLs) (Verisyse/Artisan). Four years after bilateral implantation, the uncorrected distance visual acuity was 20/25 with a correction of 20/20(-1) in both eyes. No intraoperative or postoperative complications occurred. Iris-fixated pIOLs a...

We report the case of a high myopic patient who had been implanted with angle-supported phakic intraocular lenses (pIOL) in 1990 and who subsequently and gradually developed complications in both eyes including endothelial cell loss, chronic glaucoma, cataract, pupil ovalization and severe iris atrophy. The patient was impaired by photophobia, glare, halo, loss in visual acuity and concerned ab...

The aim of this study was to evaluate the surface roughness of intraocular lenses (IOLs) generated by the manufacturing process and to determine the roughness parameters of 3D surface using atomic force microscopy (AFM). Intraocular lenses commercially available from a single manufacturer: Pharmacia & Upjohn Co. were investigated. Three intraocular lenses, model 911A CeeOn Edge, were analyzed o...

There is a need for a convenient, clinically applicable test of glare disability which can be used in the preoperative evaluation of patients with cataract. In this study, contrast sensitivity (using the Pelli-Robson letter chart), near vision, and visual acuity were compared, with and without the introduction of a glare source in 70 patients with cataract, 15 with intraocular lenses, and 19 co...

The landscape of keratoconus treatment has changed profoundly since the introduction of corneal collagen crosslinking (CXL). A decade ago, a newly diagnosed keratoconus patient could expect a treatment plan that involved gradual escalation from spectacle correction to contact lens wear, perhaps followed by an attempt to improve contact lens tolerance or spectacle acuity with intrastromal cornea...

Penetrating keratoplasty (PK) has emerged as a relatively safe means of restoring vision in corneal opacities and irregularities. Astigmatism is the most common cause of suboptimal vision after corneal transplantation despite a clear corneal graft.1,2 Based on several studies,3615%–31% of patients undergoing PK may develop postoperative astigmatism greater than 5 diopters (D). The astigmatism c...
