The 1-year results obtained in 193 eyes of 146 patients who were enrolled in a prospective study investigating photorefractive keratectomy for myopia correction with the excimer laser are reported. Because of lost follow-up (17 eyes) and reoperations (15 eyes), a complete 1-year follow-up was available in 161 eyes of 115 patients that were included in the(More)
OBJECTIVE To evaluate prospectively a diffractive (811E, Pharmacia; power add +4.0 D) versus a refractive (PA154N, Allergan; power add +3.5 D) designed multifocal lens. PARTICIPANTS Eighty patients planned for cataract surgery without additional ocular pathologies were randomized into the diffractive or refractive group, respectively. INTERVENTION A(More)
PURPOSE To ascertain whether the change in refraction caused by paired lamellating corneal incisions in cadaver eyes could be achieved in living eyes and whether wound healing influences this effect. SETTING Virchow Hospital Eye Clinic, Humboldt University, Berlin, Germany. METHODS This prospective study included 45 patients who had a follow-up of 15(More)
To evaluate the efficacy, predictability, and stability of myopic photorefractive keratectomy (PRK), the authors completed a 1-year follow-up study on a consecutive series of 26 sighted eyes undergoing this procedure. The results of this follow-up are presented. In addition, side effects and complications in another 255 sighted eyes with a follow-up of 3(More)
PURPOSE To investigate the influence of incision depth and site on wound strength and postoperative astigmatism. SETTING Virchow Memorial Hospital Eye Clinic, Berlin, Germany. METHODS In this prospective, randomized study, 180 patients with a 7.0 mm tunnel incision depth of 300 and 500 microns; limbal incision and scleral incision; temporal scleral(More)
• Background: After curvilinear capsulorhexis in cataract surgery often a double-ring shape of the remaining capsular margins can be observed. In order to better understand this phenomenon we performed a histological study of excised capsules after continuous curvilinear capsulorhexis. • Methods: Ten anterior capsular specimens from cases with double-ring(More)
Introduction: Corneal endothelial involvement can be found in pseudoexfoliation syndrome (PEX). Evaluation of possible differences in endothelial cell loss following cataract extraction was compared to normal eyes. Patients and methods: In a controlled clinical study we prospectively studied 20 patients with PEX and compared them with an age-matched(More)
The value of magnetic resonance tomography (MRT) for the diagnosis of choroidal melanomas is illustrated with reference to 26 cases. The geometric dimensions of the tumors are in good agreement with findings obtained by ultrasonography. The relaxation time T2 varies between 85 and 120 msec in contrast to 145-210 msec in subretinal hemorrhages and 190-400(More)
The anatomic localization of the glucose transport protein in the eyes of rats, rabbits, baboons, marmosets, and humans with [3H]cytochalasin B using in vitro autoradiography showed high densities of glucose carrier densities. These densities were seen in the ciliary body, especially ciliary processes, iris, retina, and in some species, the trabecular(More)
