Filter by:To analyze the evidence for clinical safety, usability, acceptability, satisfaction, appropriateness, and cost-effectiveness of Dora for recognizing patients who require additional in-person evaluation post cataract surgery. To assess Dora's sensitivity and specificity in cataract surgery management To determine what can be learnt to enhance AI technology in the field of ophthalmology especially when working with culturally diverse patients such as Punjabi and Chinese speaking patients.
The purpose of this study is to investigate the anterior and posterior structure and functional changes and vascular alterations when performing phacoemulsification at high IOP vs low, more physiological IOP using Centurion® Vision System with Active Sentry® handpiece. These devices are approved by the US Food and Drug Administration (FDA).
The purpose of this study is to evaluate the long-term safety of the IC-8 Apthera intraocular lens (IOL).
The goal of this clinical trial is to evaluate the effectiveness of Low Level Light Therapy (LLLT) in reducing the incidence or alleviating the severity of DED due to meibomian gland dysfunction in otherwise healthy patients undergoing cataract surgery. Participants will be randomly assigned in a 1:1 ratio to either a treatment group or a control group. The treatment group will receive LLLT one week before and one week after cataract surgery; the control group will not recieve LLLT at any time. Researchers will compare the treatment and the control group to see if patients receiving LLLT present with reduced signs and symptoms of ocular surface dysfunction with respect to the control group.
The goal of this interventional, real world data study is to evaluate the impact of preservatives on the post-cataract ocular surface. The main question is to learn about an effect of preservatives on the eye surface. The study aims to answer some important questions: - if the usage of preservatives has an impact on the eye surface healing process after cataract surgery - if patient comfort and quality of life improve more or more rapidly with preservatives-free eye drops. Participants will be asked to undergo standard procedure of peri-cataract surgery care and in addition to survey about the ocular surface state. Researchers will compare group that takes preservatives-free dexamethasone 0.1% with standard dexamethasone 0.01% solution to see if post-surgery eye surface healing properties differ from both groups.
In cataract surgery, the opaque lens is replaced by an artificial intraocular lens. The procedure also allows for correction of an refractive error such as myopia, hyperopia or astigmatism. In case of correction of an astigmatism, the axis intraocular lens has to be alligned to the axis of the corneal astigmatism. There are serveral options, the intendet position of the axis can be marked on the cornea, either manually using ink and a special caliper or with an automatic laser device. The aim of this study is to assess the accuracy of topography guided automatic marking of the intended IOL-axis in toric IOL-implantation in femtosecond laser assisted cataract surgery (FLACS)
Medicontur hydrophilic posterior chamber monofocal intraocular lens (IOLs) are indicated to improve vision at far distance in adults with cataract and/or ametropia (hyperopia, myopia), secondarily to removal of the crystalline lens. The intraocular lens is intended to be surgically implanted into the eye with the purpose of restoring optical function in the aphakic eye to provide an optical system with high predictability of the precalculated dioptric power. The study will be performed partially as a retrospective study with patients enrolled who had been implanted with 690AD or 690ADY IOLs mono- or binocularly between September 2021 - March 2022. Data from five visits will be collected: - Baseline preoperative (maximum 90 days prior to surgery)- retrospective - IOL implantation Day 0 - retrospective - Postoperative visit at Day 1 (+/- 0 days) - retrospective - Postoperative visit at 1 month (+/- 2 weeks) - retrospective - Postoperative visit at 12 months (+/- 3 months) - consent and prospective visit
To assess if the Alcon Argos Biometer utilizing the Barrett Universal II formula for IOL calculations can give a non-inferior outcome when compared to the Zeiss IOL master 700 utilizing the (PCA) with the Barrett Universal II (TK) formula, when comparing the (mean absolute prediction error of the predicted target spherical equivalencies).
The aim of this study was to determine the effect of relaxation exercises applied before cataract surgery on the anxiety level of elderly individuals.
The goal of this randomized clinical trial study is to compare safety profile undiluted intracameral moxifloxacin vs levofloxacin during cataract surgery. The main question it aims to answer is whether moxifloxacin and levofloxacin have similar safety profile. Participant will be randomized into two treatment arms. All participant will receive standardized treatment before, during, and after surgery and will be followed up at one day, one week, and one month after surgery.
