Active clinical trials for "Cataract"

In this project, the investigators aim to compare the safety, efficacy, and predictability outcomes of conventional CEIOL surgery to Femtosecond-laser-assisted CEIOL (FLACS) in an effort to improve cataract surgery outcomes. The investigators hypothesis is that FLACS may lead to preservation of endothelial cells compared to conventional CE IOL.

It is reported that it takes a period form 22 weeks pregnant to the first 45 months of life for macular region to develop from structural formation to functional integrity. However, children are still in the critical period of plastic visual development, for their visual acuity has not yet reached the level of adults. Similarly macular retinal structure may develop with age. It is very important to study in macular thickness of this period and to have a proper cognition of it and the relation between macular thickness and other ocular parameter for the research of retinal development and diseases and the early screen of fundus diseases.

The purpose of this study is to observe the axial IOL rotation after surgery with a capsular tension ring (CTR) and a MC6125 AS IOL. At the end of surgery the orientation of the IOL is documented with a short video clip via the operating microscope unit. Follow-up examinations are performed 1 hour, 1 week and 6 months after surgery. Rotational stability of the IOL is assessed using retroillumination images with a method to avoid bias from cyclorotation or head tilt.

The purpose of this study is to evaluate intra-operative phacoemulsification machine metrics after phacoemulsification with the CENTURION® vision system configuration compared with the INFINITI® vision system configuration.

Age-related cataract is the main cause of impaired vision in the elderly population worldwide. The only treatment that can restore functional visual ability is cataract surgery where the opacified crystalline lens is removed by phacoemulsification and an artificial intraocular lens is implanted into the remaining capsular bag. Cataract operations are generally very successful, with a low risk of serious complications. The most common reason for impaired vision after uneventful cataract surgery in otherwise healthy eyes is the development of posterior capsule opacification (PCO). PCO is a physiological change (thickening, opacification and clouding) of the capsular bag expected after cataract surgery, because the lens epithelial cells (LECs) undergo hyperplasia and cellular migration. PCO is treated with Nd:YAG capsulotomy, a quick outpatient procedure that uses a laser to open a central hole in the posterior capsular bag. Modifications in IOL design and material lead to a decrease in the incidence of PCO. During the past two decades, refinements in surgical technique were made resulting in today's small incision phacoemulsification surgery. Nowadays a multitude of microincision IOLs are available, many of them similar but of course with some differences in regard to the chemical composition of the acrylic material and the IOL design. The purpose of this study is to compare the development of posterior capsule opacification (PCO) and the frequency of treatment between two different microincision IOLs over a period of 2 years.

The objective of the study is to assess how DisCoVisc Ophthalmic Viscosurgical Device (OVD) compares with Healon and Amvisc Plus in the protection of corneal endothelial cells, and the ability to maintain anterior chamber space, in routine cataract surgery.

Study of T-PRED(TM) Compared to Pred Forte(R)

The aim of the study is to evaluate the safety and effectiveness of a new cartridge for the implantation of foldable intraocular lenses.

The study objective is to compare traditional and Wong methods of wound hydration for wound sealing following cataract surgery.

. Study Objective: The objective of this study is to determine the safety and effectiveness of the OculusGenTM Biodegradable Collagen Matrix Implant in phacotrabeculectomy surgery. The primary endpoint is to prove the effectiveness via the reduction of Intraocular Pressure, and the secondary endpoint is to prove the safety via the incidence of complications and adverse events. . Study Design: The study is designed as a historical controlled study. Patient who meet the inclusion/exclusion criteria and sign the informed consent form will be included for this study. The allocation of subjects is non-randomized, and there is a single group for assignment. . Follow-Up: This investigation is including 7 post-operative visits and follow-up within 6 months from the date of surgery. Patients should be seen at postoperative days 1, 7, 14, 30, 60, 90 and 180. The visit window of ± 7 days is allowed for the 30, 60, 90 and 180 day visits. The further follow-up of subject after trial is continually tracked by the investigator.
