Optometric Follow-up After Cataract Surgery

CataractAge-related Cataract

This study will investigate the effectiveness of an optometric follow up of cataract surgery versus an ophthalmic surgeon follow up. It will investigate patient satisfaction,safety and cost.

Ultrasonic System for Cataract Characterization and Optimal Phacoemulsification Energy Evaluation...

CataractUltrasound Therapy; Complications

This study aims to assess the performance of an ultrasonic system for automatic classification of cataract type and severity, as well as the estimation of the optimal phacoemulsification energy. Ultrasonic signals from the lens will be acquired with the Experimental Medical Device (ESUS) in participants with cataract, and in healthy subjects (control). The proposed technique may represent an important advance in cataract treatment. The quantitative and automatic classification of cataract type and severity, and the estimation of the optimal phacoemulsification energy is may represent a valuable tool for surgical planning, reducing complications associated to excessive levels of phacoemulsification energy, as well as the times spent on surgeries. This device may be relevant not only for patients, but also for public health systems, reducing waiting lists and associated costs.

Endothelial Cell Loss After Phacoemulsification Intra and Supracapsular

Cataracts

Cataract is the clouding of the lens of the eye, which initially prevents clear vision and eventually progresses to blindness if left untreated. Cataract remains the leading cause of blindness and an important cause of visual impairment across the globe. Cataract surgery by ultrasonic phacoemulsification is the most common surgery practiced in France (600 000/year) Two sub-categories of phacoemulsification coexist : Endocapsulars techniques represented by Divide-and-Conquer and Phaco-Chop ; and Supracapsular techniques mainly represented by Subluxation (similar to Tilt-and-Tumble) The corneal endothelium plays an important role in maintaining the dehydrated state and the transparency of the cornea. Some degree of endothelial cell loss invariably occurs in all types of cataract surgery but the amount of endothelial cell loss may varies with the type of surgical technique The aim of the study is to evaluate the density of the central corneal endothelial cells before and after cataract surgery comparing two phacoemulsification techniques (Divide-and-Conquer vs Subluxation)

Effects of Preoperative Using of Eye Patches on Prevention of Emergence Agitation After Cataract...

AgitationChild1 more

This study is a single-center, prospective, randomized, controlled trial. To investigate if preoperative using of eye patch will decrease emergence agitation, and to provide a better method of decreasing emergence agitation to pediatric ophthalmic anesthesiologists.

Viscoat Versus Visthesia. A Comparative Study of Post-cataract Endothelial Cell Loss

Cataract

Objective of this study is the comparative assessment of the beneficial impact of the Viscoat viscoelastic (OVD) and Visthesia OVD on endothelial cells and corneal edema following torsional-ip cataract extraction surgery. Participants will be recruited from the Cataract Service of the University Hospital of Alexandroupolis (UHA) in a consecutive-if-eligible basis. Eligibility criteria include diagnosis of senile cataract with stage 3 nuclear opalescence according to the Lens Opacities Classification System III (LOCS-3) grading scale. By means of a custom computer randomization program all participants will randomly populate two study groups according to the OVD used (ie. viscoat or visthesia).

Functional Vision With ACRYSOF® IQ IOLs Blue Light Filtration

Cataract

The purpose of this study is to compare the reaction time (as measured by braking reaction time in seconds during simulated driving) under glare and no-glare conditions in subjects implanted with ACRYSOF® IQ intraocular lenses (IOLs) to subjects implanted with clear IOLs. This study will enroll subjects previously implanted with IOLs in both eyes for at least 3 months.

Dysfunctional Lens Index Serves as a Novel Surgery Decision Maker for Age-related Cataracts

Age-related Cataract

To study the correlations among the dysfunctional lens index (DLI), Lens Opacities Classification System III (LOCS III) nuclear opalescence grading score, preoperative corrected distance visual acuity (CDVA), the objective scatter index (OSI) and Scheimpflug based average lens density in age-related cataracts. To investigate the potential of the DLI as a novel surgery decision maker via the Operating Characteristic (ROC) curve analysis.
