Comparison of the AcrySof IQ aspheric blue light filter and the AcrySof SA60AT intraocular lenses.

Purpose: The development of aspheric intraocular lenses (IOL) designed to compensate for the positive spherical aberration of the cornea has been shown to improve the image quality of pseudophakic eyes. This prospective clinical study compared an aspheric IOL with a blue light filter (AcrySof IQ) with its spherical platform--the SA60AT IOL with conventional optic.

Methods: After uneventful phacoemulsification, 42 and 20 eyes were implanted with the AcrySof IQ aspheric lens and the SA60AT, respectively.

Intraindividual comparison of a blue-light filter on visual function: AF-1 (UY) versus AF-1 (UV) intraocular lens.

Purpose: To evaluate the effect of the AF-1 (UY) blue-light-filtering intraocular lens (IOL) with a yellow chromophore (Hoya) on visual function, including contrast vision and color perception.

Settings: Five clinical ophthalmology centers in Germany.

Methods: Two types of IOLs that were identical except for a blue-light filter on 1 were compared in a prospective randomized multicenter study with intraindividual comparisons.

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).

Impact of a modified optic design on visual function: clinical comparative study.

Purpose: To determine whether implantation of an intraocular lens (IOL) with a modified anterior surface designed to compensate for the positive spherical aberration of the cornea in eyes of cataract patients results in improved pseudophakic quality of vision.

Setting: Department of Ophthalmology, Bundesknappschaft's Hospital, Sulzbach, Germany.

Methods: In an intraindividual randomized study of 45 patients with bilateral cataract, an IOL with a modified anterior surface (Tecnis Z9000, Pharmacia) was compared with a biconvex lens with spherical surfaces (SI-40, Allergan).

Vitrectomy with arteriovenous decompression and internal limiting membrane dissection in branch retinal vein occlusion.

Purpose: The therapeutic armamentarium for functional improvement after branch retinal vein occlusion (BRVO) is limited with uncertain efficacy. Some surgeons have proposed surgical decompression of the vein at the arteriovenous (AV) crossing.

Methods: Forty-three patients with BRVO were treated in the authors' department from August 1999 to April 2001 with AV decompression.

Results of surgery for epiretinal membranes and their recurrences.

Aims/background: This study was performed to identify factors predictive for recurrence of idiopathic and secondary epiretinal membranes after vitrectomy. Long term visual outcome was determined and compared with eyes without recurrence of epiretinal tissue.

Methods: Out of 350 consecutive cases vitrectomised for removal of epiretinal macular membranes, 42 patients (42 eyes) with recurrence of epiretinal membranes were re-examined and their records reviewed.
