Filter by:The objective of this study is to evaluate uncorrected distance vision and quality of vision as measured by the McAlinden QoV questionnaire 3 months following the final lock-in treatment of the implanted RxSight Light Adjustable Lens (RxLAL) with the Light Delivery Device (LDD) in subjects with preoperative keratometric astigmatism. This is an exploratory study. No primary effectiveness endpoints will be defined.
We are conducting a trial evaluating the performance of trifocal versus extended depth of focus intraocular lenses. These lenses will be implanted in otherwise healthy individuals with visual problems due to bilateral cataracts. Patients must be seeking an improvement in their visual performance with a special focus on presbyopia correction.
The overall five-year goals of the project are to develop novel technology to provide actionable new information through provision of live volumetric imaging during surgery, improving surgical practice and outcomes. The investigators believe this technology will enable novel ophthalmic and other microsurgeries not possible due to current limitations in surgical visualization.
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 Post Marketing Study is to study the safety and effectiveness of the ACRYSOF IQ PanOptix intraocular lens (IOL) in an Indian population.
Primary objective of the study is the assessment of the patients' discomfort following cataract extraction surgery by means of phacoemulsification and intraocular lens implantation.
This is a two-arm, parallel group, open-label, randomized controlled trial to compare the visual acuity, visual quality, operative complications and the satisfaction of patients between primary posterior capsulorhexis group and laser capsulotomy group of cataract patients combined with primary posterior capsular opacification (PPCO).
objective: To evaluate the efficacy of the ophthalmic emulsion PRO-145 in the treatment of inflammation and pain after phacoemulsification. Hypothesis: The use of the ophthalmic emulsion PRO-145 is effective in decreasing the inflammatory response evaluated by means of cellularity in the anterior chamber, after phacoemulsification. Methodology: Phase III clinical trial, double-blind, controlled, parallel group, multicentre, randomized. Number of patients: 178 subjects divided into 2 groups (89 subjects per group), who will provide an eye for the evaluation of efficacy. Diagnosis and main inclusion criteria: Diagnosis: Postoperative phacoemulsification and foldable intraocular lens placement in a bag.
In this study, the investigators conducted a cross-sectional, face-to-face investigation to evaluate the behavioral and psychological disorders and the risk of ADHD among children with bilateral congenital cataracts using the Conners'Parent Rating Scale (CPRS) questionnaire, an assessment tool for screening ADHD that obtains parental reports of childhood behavioral problems in research and clinical settings.15-17 Age-matched children with normal vision and the Chinese urban norm were used as controls.
To compare the impact of two phacoemulsification techniques (subluxation versus divide-and-conquer) on postoperative corneal edema at postoperative hour 1 and day 4.
