Impact of personality characteristics on patient satisfaction after multifocal intraocular lens implantation: results from the "happy patient study".

Purpose: This prospective multicenter study assessed personality characteristics that may influence patient satisfaction after implantation of multifocal intraocular lenses (MIOLs).

Methods: One hundred eighty-three patients who underwent bilateral implantation of different MIOLs were enrolled. Uncorrected and corrected distance visual acuity for distance and near (ie, UDVA, UNVA, CDVA, and CNVA) were assessed preoperatively and 3 and 6 months after implantation.

[Vitreous body and retinal vein occlusion].

Purpose: The aim of this study was to evaluate whether the adhesion status of the posterior vitreous cortex (PVC) towards the internal limiting membrane (ILM) has an impact on the development of retinal vein occlusion (RVO).

Material And Methods: In a retrospective analysis the operation protocols of 238 eyes receiving pars plana vitrectomy (ppV) and radial optic neurotomy (RON) for central retinal vein occlusion (CRVO) or ppV in combination with arteriovenous sheathotomy (AVS) for branch retinal vein occlusion (BRVO) were evaluated with respect to the intraoperative status of posterior vitreous body adhesion. The results were compared with age-matched healthy controls.

Purpose: To determine the impact of ciliary sulcus implantation after capsular bag defect on tilt and decentration of foldable intraocular lenses (IOL) measured by a novel device.

Methods: This prospective noncomparative single-center investigation included patients (N = 10) older than age 60 who underwent cataract surgery with a posterior capsular bag defect and implantation of a threepiece hydrophilic aberration neutral IOL (OphthalmoPro AC 7013) in the ciliary sulcus. All eyes (N = 10) were examined using the OPD-Scan II (Nidek).

[Functional results with two multifocal intraocular lenses with different near addition].

Background: The reduction of the near addition of multifocal intraocular lenses from +4 D to +3 D should improve the visual function in the intermediate distance. The ReSTOR +3 D is a multifocal lens with a near addition of 3 D.

Patients And Methods: In a prospective study the new ReSTOR +3 D was compared to the former ReSTOR platform with 4 D near addition.

[Clinical results of the aspheric intraocular lens FY-60AD (Hoya) with particular respect to decentration and tilt].

Background: Aspheric intraocular lenses (IOLs) aim to improve visual function and particularly contrast vision by neutralizing spherical aberration. One drawback of such IOLs is the enhanced sensitivity to decentration and tilt, which can deteriorate image quality.

Methods: A total of 30 patients who received bilateral phacoemulsification before implantation of the aspheric lens FY-60AD (Hoya) were included in a prospective study.

Decentration and tilt of a single-piece aspheric intraocular lens compared with the lens position in young phakic eyes.

Purpose: To compare the tilt and decentration of a single-piece aspheric intraocular lens (IOL) and the position of the natural crystalline lens in young individuals.

Setting: Department of Ophthalmology, Knappschafts Hospital, Sulzbach, Germany.

Methods: This prospective noncomparative single-center study included volunteers younger than 40 years with no ocular abnormalities (crystalline lens group) and patients older than age 62 who had uneventful cataract surgery and Tecnis ZCB00 IOL implantation (IOL group).

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.

[Functional vision training after MIOL implantation].

In a prospective and intraindividually comparative study, we investigated visual performance after implantation of two multifocal intraocular lenses. Eight patients received the ReSTOR (Alcon) bilaterally, and eight patients received the Tecnis ZM900 (AMO). The nondominant eye of each patient was trained based on the concept of perceptual learning using orientation discrimination of near-vertical bars.

Intraindividual comparison of the effect of training on visual performance with ReSTOR and Tecnis diffractive multifocal IOLs.

Purpose: Several studies have shown that after multifocal intraocular lens (IOL) implantation visual function improves gradually over a period of several months. To accelerate this learning process, a prospective, intraindividual comparative study was performed to investigate the efficacy of a special visual training program on the postoperative visual performance.

Methods: Sixteen patients with bilateral phacoemulsification and multifocal IOL implantation in both eyes (Alcon ReSTOR [n = 8] and AMO Tecnis ZM900 [n = 81) received computer-based visual training 6 weeks postoperatively based on the concept of perceptual learning of discrimination line orientations.

[The aspheric blue light filter IOL AcrySof IQ compared to the AcrySof SA60AT : influence of IOL power, pupil diameter, and corneal asphericity on postoperative spherical aberration].

Background: The aspheric optic design of intraocular lenses (IOL) aims to minimize postoperative ocular spherical aberration (SA). The effect of a standardized IOL asphericity depends on IOL power, pupil diameter, and corneal asphericity. The impact of these factors was investigated in a comparative study.

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

[Radial optic neurotomy: efficacy monitoring using venous ophthalmodynamometry].

Background: Retinal central venous outflow pressure (VOP) can be measured with a new ophthalmodynamometer (Meditron, Völklingen, Germany). Radial optic neurotomy (RON) is a new surgical approach for central retinal vein occlusion (CRVO) which is still controversially discussed. Particularly the early formation of retinochoroidal collaterals is intended to achieve normalization of the preoperatively increased pressure in the central retinal vein.

[Incidence and prophylaxis of retinal detachment following pars plana vitrectomy].

Purpose: The aim of this study was to investigate the incidence of retinal detachment (RD) following pars plana vitrectomy and the efficacy of prophylactic means by cryoapplication central to the superior sclerotomies.

Patients And Methods: From February 2002 to January 2005 a total of 2,298 eyes received a pars plana vitrectomy in our department. Excluding eyes with previous peripheral coagulation therapy, preexisting retinal detachment, and endophthalmitis 1,640 eyes could be reexamined at least 6 months after surgery (mean: 17+/-12 months).

[Surgical approach to retinal vein occlusion].

Retinal vein occlusions are the second most common vision threatening retinal vascular disorders. Our therapeutic armamentarium for functional improvement was very limited in the past for all types of retinal vein occlusions (branch, central and hemi-central retinal vein occlusion). Also pathomechanism and risk factors are not completely understood yet.

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).

Eye models for the prediction of contrast vision in patients with new intraocular lens designs.

Theoretical calculations of the polychromatic modulation transfer function (MTF) and wave-front aberration were performed with physiological eye models. These eye models have an amount of spherical aberration that is representative of a normal population of pseudophakic eyes implanted with two different types of intraocular lens (IOL) made from high-refractive-index silicone. These theoretical calculations were compared with the measured contrast sensitivity function (CSF) under mesopic lighting conditions and with wave-front aberration (obtained with a Hartmann-Shack wave-front sensor) collected from 37 patients bilaterally implanted with the same types of lens.
