Optic edge design as long-term factor for posterior capsular opacification rates.

Objective: To compare the difference in posterior capsular opacification (PCO) between highly refractive silicone and hydrophobic acrylic foldable intraocular lenses (IOLs) with sharp and round edge designs 3 years after in-the-bag IOL implantation in subjects undergoing bilateral cataract surgery.

Design: Open-label, prospective, randomized, multicenter clinical trial.

Participants: Two hundred and eighty-eight patients with bilateral surgery for senile cataract operated in German university clinics, eye hospitals, and private ophthalmic surgical centers (Aachen, Ahaus, Bad Hersfeld, Frankfurt/Main, Jena, Rosenheim, and Sulzbach/Saar).

Functional outcomes after implantation of Tecnis ZM900 and Array SA40 multifocal intraocular lenses.

Purpose: To evaluate the functional outcome after implantation of the Tecnis ZM900 multifocal intraocular lens (IOL) (AMO) and the Array SA40 multifocal IOL (AMO).

Setting: Department of Ophthalmology, Bundesknappschaft s Hospital, Sulzbach, and the Department of Ophthalmology, Marienhospital, Aachen, Germany.

Methods: In a prospective comparative 2-center trial, Tecnis ZM900 and the Array SA40 multifocal IOLs were bilaterally implanted in 50 patients (50 eyes Tecnis, 50 eyes Array) by 1 surgeon at each center.

Posterior capsule opacification after implantation of CeeOn Edge 911A, PhacoFlex SI-40NB, and AcrySof MA60BM lenses: one-year results of an intraindividual comparison multicenter study.

Purpose: To perform an intraindividual comparison of posterior capsule opacification (PCO) with 2 foldable intraocular lenses (IOLs) and a foldable acrylic IOL 1 year after in-the-bag implantation.

Settings: Seven German ophthalmology centers.

Methods: In an open prospective randomized multicenter study, each center intraindividually compared a high-refractive-index, sharp-edged optic silicone IOL (CeeOn Edge 911A, Pharmacia) with a high-refractive-index, round-edged optic silicone IOL (PhacoFlex SI-40NB, Allergan) or a sharp-edged optic acrylic IOL (AcrySof MA60BM, Alcon).

[Highly refractive silicone lens with sharp optic edge (CeeOn Edge, Model 911): one year results of a multicenter clinical trial on performance and efficacy].

Purpose: To investigate the performance and efficacy of a new high refractive index (1.46) silicone intraocular lens with sharp optic edges.

Materials And Methods: In this open prospective multicenter study 149 patients underwent cataract surgery and implantation of CeeOn Edge in one eye.
