Filter by:On the day of surgery, the first eye to be operated is randomised to receive a Vivinex , HOYA Surgical Optics GmbH or an SN60WF, Alcon, Fort Worth, Texas. The second eye to be operated receives the other IOL type. A complete biomicroscopic examination, visual acuity testing using autorefractometer, contrast sensitivity testing, and standardised retroillumination photography for PCO evaluation, will be performed 6 month (30-60 days), 1.5 years (± 3 months) and 3 (± 3 months) years postoperatively.
The investigational device is an approved biometry device to perform biometric measurements preoperatively to calculate the needed IOL power. First, two native measurements at the IOL Master will be performed. Thereafter randomly assigned artificial tears are instilled in the eye and biometry will be repeated within 30 seconds, as well as after 2 and 5 minutes. At least 24hours after those measurements, two native measurements at the IOL Master will be performed. Thereafter, the not yet used artificial tears are instilled in the eye and biometry will be repeated within 30 seconds, as well as after 2 and 5 minutes. Examinations will be implemented in accordance with the approved investigational plan on subjects and includes: repeated biometry without and with artificial tear drops.
The goal of this study is to evaluate subject outcomes and spectacle independence with intraoperative aberrometry and trifocal IOL implantation.
The objective of the study is to evaluate the safety and effectiveness of the Bausch & Lomb CVisc50 cohesive OVD compared to the Alcon ProVisc® cohesive OVD when used in cataract surgery.
This study was a retrospective observational cohort analysis of subjects aged 65 years and older, who underwent bilateral cataract surgery within a single (15 hospital) healthcare system, to determine the association between type (conventional or blue-light filtering) of implanted intraocular lens and survival.
This study is a prospective, single-arm, observational study of the Catalys Precision Laser System in real-world clinical practice. The study will be conducted at one site at the Boao Super Hospital in Lecheng International Medical Tourism Pilot Zone of Hainan province in China. The study is being conducted to evaluate the overall performance of the Catalys Precision Laser System. One or both eyes of each subject will be included in study. The Catalys system is used as part of cataract surgery to create LASER cuts as intended by the surgeon to aid in cataract surgery, without adversely impacting the risk to the patient.As such, the endpoints of surgeon rating of completeness of corneal incisions, anterior capsulotomy and phacofragmentation and any device related adverse events from the time of Catalys System use to 1-month postoperative follow-up should adequately cover the evaluation of the intended use of the Catalys System.
Purpose: The aim of the study was to compare the analgetic effect of two solutions of intracameral anesthesia in patients undergoing cataract surgery and assess the factors influencing the patients' postoperative activities. Methods: In this prospective, single-blind, randomized study, a group of 62 patients undergoing cataract surgery received Mydrane (Mydrane group) or a combination of 1% solution of lignocaine and 0.025% solution of adrenalin (reference group) as an intraocular anesthetic. The analgetic effect of these two anesthetic methods was evaluated using psychological tools - Visual Analog Scale for Pain (VAS Pain) and Brief Pain Inventory-short form (BPI) on the next day after the surgery.
This is a multicenter, prospective, randomized, subject- and evaluator-masked, bilateral-implant study conducted at up to 15 sites worldwide. A total of up to 280 subjects will be randomized in a 1:1 ratio for implantation with either the TECNIS Symfony plus IOL Model ZHR00V or the Trifocal IOL. This will ensure that data from at least 100 subjects in the TECNIS Symfony plus lens group and at least 100 subjects in the Trifocal lens group will be available for analysis at the 6-month follow-up timepoint. All subjects will be followed for up to 6 months postoperative.
