Active clinical trials for "Cataract"

There is a correlation between phacodepth required for full thickness nuclear crack and the various grades of cataract

Rigorous and regular follow-up is essential to successful management of childhood cataract, but it is often ignored by parents and especially difficult to be delivered in China, such an average-medical-resource-limited country. Health programmes that use mobile communication technologies are emerging with the aim of strengthening health systems. The investigators aimed to assess whether mobile phone short message service (SMS) for parents of cataract children involved in the Childhood Cataract Program of Ministry of Health of China (CCPMOH) improved follow-up adherence and detection rate of the timing of surgery, postoperative complications and necessary replacement of glasses.

Objective of this study is the comparative assessment of the impact of torsional and liquefaction technologies on endothelial cells (ECC), corneal edema (CCT) and corneal sensitivity (CCS) in a sample of cataract patients. Participants were recruited from the Cataract Service of the UHA in a consecutive-if-eligible basis. Eligibility criteria included diagnosis of senile cataract with stage 2 nuclear opalescence according to the Lens Opacities Classification System III (LOCS-3) grading scale [10]. By means of a custom computer randomization program all participants randomly populated two study groups according to the cataract-extraction technology used: a) Torsional group (TG) and b) Liquefaction group (LG).

This study will determine the incidence and severity of dry eye in patients undergoing cataract surgery as determined by grade on the International Task Force (ITF) scale.

The VIVA study is focused on Alzheimer's disease patients with a low vision due to a bilateral cataract. The aim is to study cataract surgery results on patients' autonomy, behaviour, and mood. In fact those dement elderly patients suffer from a progressive loss of superior functions, with loss of autonomy, behaviour and mood degradation, associated with physical disabilities. The work hypothesis is that a loss of sensorial functions, particularly visual, is an aggravating factor of NEURO-cognitive troubles and absence of communication with outside circle. The protocol consists in investigating superior functions, autonomy, and behaviour troubles of the participating patients, with the help of a series of neuropsychological tests used one month before and three months after cataract operation on the eye with the worst vision. Independently of the study, patients must have given an informed consent to cataract surgery. Their participation lasts 4 months+/- 1 month. The aim of the study is to evaluate whether the cataract surgery improves patients' behaviour, autonomy and mood and possibly to show evidence onf drawbacks in of such a practice.The main objective targets to cataract surgery benefice on patients suffering from both Alzheimer's disease and impeding cataract, aiming to improve behaviour troubles. The specific objective is to measure this benefice in correlation with visual acuity improvement.

To determine what effect a blue light filtering Intraocular Lens (IOL) has on macular pigment levels.

To assess visual performance in patients with low levels (0.5-0.75 Diopters) of corneal astigmatism.

The purpose of this study is to compare the visual outcomes with bilateral implantation of Tecnis MF and ReSTOR intraocular lenses (IOLs) 6 months post cataract surgery.

This is a phase 3, randomized, double-blind, placebo-controlled study to evaluate new or worsening lens opacifications in men with non-metastatic prostate cancer receiving denosumab for bone loss due to androgen deprivation therapy.

Incision size in cataract surgery is related to induced surgical astigmatism, chamber stability, and surgical efficiency. Sleeves of different diameters change the size of the surgical incision and amount of fluid allowed into the eye during the surgical procedure for a given set of surgical parameters. Optimization of surgical parameters requires review of surgical efficiency including: fluid usage, energy usage, and total surgical time. With optimized surgical parameters recommendations can be made to increase the efficiency and safety of cataract surgery.
