Filter by:Retrospective collection of data from medical records, multicenter, post-market clinical follow-up study.
Prospective, multicenter, paired-eye, randomized, subject/evaluator-masked clinical investigation of the experimental EndoCoat OVD versus the control EndoCoat OVD.
This is a prospective and retrospective, single-center, single-arm, open-label clinical study of the TECNIS Synergy™ IOL. The study will enroll up to 100 subjects from a single site in China. All implanted subjects will be followed for 12 months postoperatively.
Observational post-marketing study with prospective follow-up of CE marked medical devices aimed at the treatment of hyperopia and astigmatism in patients with cataract. The objective is to evaluate the clinical results of the implantation of the monofocal aspheric bitoric intraocular lens (IOL) with AT-TORBI 709 plate haptics in cataract surgery of hyperopic eyes with astigmatism.
This is a prospective, single-center, single-arm, open-label, clinical study of the investigational TECNIS Symfony® Toric IOL. The study will enroll up to 100 subjects from a single investigative site in China. The subjects will be followed for 12-months postoperatively.
This is a post-market, prospective, randomized, multi-center, bilateral, open-label, cross-over, comparative clinical study. Study group will undergo preoperative LipiFlow treatment and Control group will not receive preoperative LipiFlow treatment. Three months postoperatively, both groups will be evaluated for clinical outcomes and the Control group will receive LipiFlow treatment as the cross-over group. The Control group will be evaluated at 4 months postoperative for clinical outcomes.
The purpose of this study is to compare corneal incision size after IOL implantation with the use of one of four IOL delivery systems (three preloaded IOL delivery systems and one manually loaded IOL delivery system).
The purpose of this study is to clinically evaluate the visual performance of two commercially available presbyopia-correcting Trifocal IOLs.
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)
The purpose of this study is to demonstrate that the Centurion® Vision System (CVS) used with the 45° Balanced Tip will result in less Cumulative Dissipated Energy (CDE) than the lnfiniti® Vision System (IVS) used with the 45° Mini-Flared Kelman (MFK) tip during cataract extraction surgery via phacoemulsification of cataract grades NII- NIV [Lens opacities classification system II (LOCSII)].
