Active clinical trials for "Cataract"

So far, only limited data is available regarding the natural course in Congenital Cataract Facial Dysmorphism Neuropathy Syndrome (CCFDN) and sporadic and hereditary inclusion body myopathies (IBM). Several criteria and outcome measures have led to contradicting results. The investigators want to retrospectively assess the natural course of the disease in CCFDN and IBM patients according to the data recorded during clinical routine visits.

The purpose of this study is to evaluate the visual performance of two cohorts of patients who received multifocal intraocular lenses following cataract and clear lens extraction surgeries. Comparing visual outcomes of patients who were implanted with TECNIS Multifocal IOLs in both eyes versus patients implanted with TECNIS Multifocal in one eye and ReZoom Multifocal IOL in the opposite eye.

Progression of nuclear sclerotic cataract after pars plana vitrectomy has been recognized for many years The mechanism for the rapid progression of nuclear sclerotic cataract remains unclear. The objective of this trial is to evaluate and compare the level and progression of cataract advancement in controls versus eyes that have undergone 20-gauge pars plana vitrectomy and 25-gauge pars plana vitrectomy.

The purpose of this study is to determine whether corneal endothelium cell loss during cataract surgery is higher in patients taking Tamsulosin.

Some studies indicated that the diabetic corneal endothelium is morphologically abnormal and may be at risk in any intraocular surgical procedure, while others showed no significant differences between diabetic and non-diabetic corneal endothelium.The purpose of this study is to investigate the differences in corneal endothelial cell density and morphology in diabetic patients and normal patients after phacoemulsification with intraocular lens implantation.To investigate if haemoglobin A1c can be used as a predictor of corneal endothelial cell changes after phacoemulsification.

To collect visual outcome data post AcrySof ReSTOR Aspheric +4 implantation from surgeons throughout the United States.

Topical fluoroquinolones (FQs) have achieved widespread use in ophthalmology for both the treatment and prophylaxis of ocular infections. The present study is set to determine the bacteria present on the ocular surface in patients at the time of cataract surgery and to assess the rate of resistance of ocular isolates to commonly used topical antibiotics.

To investigate ocular haemodynamics after phacoemulsification surgery To evaluate the influence in people with different autoregulation of ocular blood flow

To determine whether vitamin E supplementation reduces the risk of cataract and age-related macular degeneration (AMD) in women. To determine whether vitamin C supplementation reduces the risk of cataract and AMD in women. To determine whether beta-carotene supplementation reduces the risk of cataract and AMD in women. To determine whether alternate day, low-dose aspirin reduces the risk of cataract and AMD in women. To identify potential risk factors for cataract and AMD including cigarette smoking, alcohol intake, blood pressure, blood cholesterol, cardiovascular disease, height, body mass index, and diabetes.

The purpose of this study is to evaluate the long-term clinical acceptability and overall satisfaction with the IC-8 IOL at least 12 months post-IOL implantation.
