NCT06399211
This study is a prospective, multicenter, randomized, double masked trial comparing an investigational Monofocal Toric intraocular lens (IOL) (PODEYE TORIC CYL 1.5 D) and a commercially available non-toric monofocal IOL.
NCT07413172
This study aims to find out whether adding sodium hyaluronate, a moisturizing ingredient commonly found in artificial tears, makes autologous serum eye drops more effective for treating moderate-to-severe dry eye disease. Each participant will use one version of the drops in one eye and the standard version in the other eye. The goal is to see if the new combination provides better relief, comfort, and eye surface healing compared to the traditional formulation.
NCT07322302
The primary objective of this randomized clinical trial is to determine whether repeat trichiasis surgery performed with Bevel-Rotate Advancement Procedure (B-RAP) improves surgical success compared to Bilamellar Tarsal Rotation (BLTR) among a group of 8-10 TT surgeons in Tanzania. The study aims to enroll 1,000 individuals with PTT. The primary outcome is repeat PTT within one year after surgery. Additionally, the study will assess eyelid contour abnormalities and how they change over a two-year period as well as patient reported outcomes. If this project is successful in improving surgical outcomes, it could change the approach to treating PTT globally. Individuals with trichiasis have a significantly reduced quality of life; correcting their trichiasis long-term has the potential to improve their quality of life and their family members' quality of life considerably.
NCT05656027
Phase 3 study to evaluate the safety and effectiveness of LNZ100 \& LNZ101 for the treatment of Presbyopia.
NCT03846193
This was an open label first in human Phase I/II multicentre study of GT005 in subjects with Macular Atrophy due to Age-related macular degeneration (AMD).
NCT05414994
The objective of this application is to illustrate the core constituents of the ocular surface microbiome, describe factors that promote colonization, and assess the ocular microbiome's role in the health of the anterior segment. We will conduct a prospective, observational cohort study, including a longitudinal analysis of the ocular microbiome in adults.
NCT07267481
To determine the efficacy of switching participants who are being treated with Xiidra to acoltremon 0.003%. Hypothesis: Switching to acoltremon 0.003% will greatly improve the signs and symptoms of participants who were being treated with Xiidra at 28 days post-treatment compared to baseline.
NCT07228793
This natural history study of patients with EYS mutations from Russia and former CIS (Commonwealth of Independent States) territories will accelerate the development of outcome measures for clinical trials. Sensitive, reliable outcome measures of retinal degeneration will greatly facilitate development of treatments for retinitis pigmentosa due to EYS mutations. This approach helps to develop experimental treatment protocol, and assessing its effectiveness. The goals and expected impact of this natural history study are to: 1. Describe the natural history of retinal degeneration in patients with biallelic mutations in EYS gene in Russia and former CIS territories. 2. Identify sensitive structural and functional outcome measures to use for future multicenter clinical trials in EYS-related retinal degeneration in Russia and former CIS territories. 3. Identify well-defined subpopulations for future clinical trials of investigative treatments for EYS-related retinal degeneration in Russia and former CIS territories.
NCT04271709
The investigators are conducting a 5-year prospective, 2:1 cluster-randomized controlled trial, funded by the Centers for Disease Control (CDC), which provides vision screenings to underserved New York City residents living in affordable housing buildings in Harlem and Washington Heights.
NCT06177639
The goal of this observational study is to test the use of a novel Widefield Confocal Scanning Laser Ophthalmoscope (WiSLO) Optimized for Pediatric and Neonatal Imaging in pediatric and adult subjects who are undergoing clinical evaluation for eye disease or are healthy adult volunteers. The main questions to answer are: * Whether WiSLO will be more comfortable and satisfactory in experience for the patient and operator than commercial alternatives. * If the quality of WiSLO near infrared images will be comparable to color fundus camera imaging across population of different ages and fundus pigmentation. Participants will have the following research procedures: * Imaging of both eyes with a research noncontact WiSLO * Imaging of both eyes with a commercially available non-contact hand held fundus camera (Volk Pictor Plus) * Likert scales for adults * Pediatric Likert scales for children * CRIES scales for infants.
NCT06841575
The goal of the current study is to conduct a pilot study to test a new version of the handheld OCT device capable of auto-alignment to image the retina in adult volunteers, and adult and pediatric patients in clinic.
NCT06011798
The goal of this clinical trial is to assess the efficacy and safety of multiple doses of foselutoclax (UBX1325) in patients with Diabetic Macular Edema. The main questions the study aims to answer are: * Assess the efficacy of foselutoclax compared to aflibercept * Assess the safety and tolerability of foselutoclax
NCT05797896
An observational study to investigate the natural history and evaluate biomarkers of participants with geographic atrophy secondary to age-related macular degeneration
NCT05147701
This trial will study the safety and efficacy of intravenous and sub-tenon delivery of cultured allogeneic adult umbilical cord derived mesenchymal stem cells for the treatment of non-arteritic ischemic optic neuropathy
NCT05550740
The purpose of this clinical trial is to confirm the incidence and magnitude of axial length shortening after RLRL therapy in Chinese high myopia children and teenagers.
NCT06045299
A Multi-Center, Randomized, Double-Masked, Placebo-Controlled Phase 3 Evaluation of the Efficacy and Safety of LNZ101 and LNZ100 for the Treatment of Presbyopia
NCT06112340
The overall study objective is to continue to assess the efficacy, safety, pharmacokinetics, and pharmacodynamics of linsitinib in subjects who were enrolled in the prior VGN-TED-301 through Week 24. These subjects include VGN-TED-301 Week 24 proptosis non-responders or subjects who relapse during the Follow-Up Period of VGN-TED-301.
NCT04302220
This study intends to establish a registry cohort to enroll patients with high myopia to study the natural course of myopic optic neuropathy in Chinese adult population.
NCT05686421
In this study, participants will be imaged using two Optical Coherence Tomography (OCT) devices: device N, a standard conventional OCT device with an invention (comfortable chin and forehead rest that can be adjusted to fit each individual's size) attached to the device; and device C, the standard conventional OCT device with no invention attached. The investigators will assess whether the chin and forehead rest attachment (invention) provides a more comfortable experience for patients.
NCT03913130
Subjects completing participation in study PQ-110-001 (EudraCT 2017-000813-22 / NCT03140969) will be given the opportunity to enroll into the extension study for continued dosing if available data support current and/or future benefits for the subject. Study PQ-110-002 will provide long-term safety, tolerability, pharmacokinetic (PK), and efficacy data of QR-110.
