Filter by:The purpose of this study is to investigate whether there is a difference in best spectacle corrected visual acuity (BSCVA) in patients treated with one of the following two surgeries: (1) cataract surgery with preservation of the diseased endothelial cells ("cataract surgery only experimental intervention, investigational therapy/ arm 1); (2) cataract surgery combined with removal of the diseased endothelial cells and the attached Descemet's membrane followed by transplantation of a healthy endothelial cell layer with attached Descemet's membrane ("triple-DMEK"(""cataract surgery only", control intervention comparator therapy/ arm 2)
Granular Corneal Dystrophy is a rare hereditary disease characterized by the development of deposits within the cornea, which may in turn affect the quality of vision. Still today, all existing treatment options are based on surgical intervention and there is no minimally-invasive treatment available for the disease. The goal of this clinical trial is to test the effectiveness and safety of Neodymium-doped yttrium aluminum garnet (Nd:YAG) laser as a minimally-invasive treatment for people suffering from Granular Corneal Dystrophy. The main question it aims to answer is if Nd:YAG laser is able to disintegrate the characteristic corneal depositions in a safe manner without causing significant adverse effects. If found suitable to be part of the study, participants will first undergo a series of imaging studies to measure and characterize the corneal deposits. After completion, the participants will undergo the Nd:YAG laser treatment under local anesthesia by a corneal specialist, targeting deposits not involving the visual axis. Following the treatment, participants might need to take antibiotic eye drops for a duration of approximately one week. The participants will be required to attend two follow-up visits: one week after the treatment and 3 months after the treatment. In each one of the follow-up visits, an eye examination will be performed and the same series of imaging studies that was performed prior to the Nd:YAG laser treatment will be repeated.
The goal is to develop a nationwide registry to track longitudinal clinical outcomes of and store imaging data related to numerous corneal conditions. There are two main objectives including the establishment of the first nationwide corneal transplant registry in the United States to include information related to the donor tissue, recipient, surgical procedure, and long-term clinical outcomes. Ultimately, this prospective data collection will allow us to determine prognostic factors for successful corneal transplantation and create an algorithm to guide clinical practice based on real world outcomes. The second objective is to collect and create a database of historical, de-identified optical coherence topography (OCT) and corneal topography images to ultimately develop artificial intelligence (AI) based diagnostic and prognostic algorithms for corneal disease and surgery.
The purpose of this study is to support the safety and performance assessment of Air Optix Night and Day Aqua (AONDA) soft contact lenses for therapeutic use in accordance with updated EU Medical Device Regulation (MDR) requirements.
Aim Physiological changes in intraocular pressure as well as in the cornea and macula may occur during pregnancy. In the literature, there are limited data on ocular findings in hyperemesis gravidarum. Therefore, we have decided to investigate the effect of hyperemesis gravidarum on macular thickness, corneal thickness and intraocular pressure (IOP).
This study will be used to support assessment of AIR OPTIX® NIGHT & DAY® AQUA (AONDA) Soft Contact Lenses' safety and performance in accordance with updated European Union Medical Device Regulation (EU MDR) requirements.
The purpose of this study was to evaluate the safety and efficacy of ZVS101e administered by subretinal injection in subjects with Bietti's crystalline dystrophy (BCD) and to select the optimal effective dose.
A study to assess the safety and efficacy of K-321 in participants with FECD after simultaneous cataract surgery and descemetorhexis.
A study to assess the safety and efficacy of K-321 in participants with FECD after descemetorhexis.
The pathophysiology of the most common corneal endothelial dystrophies (Fuchs' Corneal Endothelial Dystrophy, FECD) is beginning to be dismembered. There is a significant heterogeneity in the clinical forms and the investigators have just highlighted a great diversity of histological forms that seem to define distinct groups.
