Active clinical trials for "Corneal Edema"

The purpose of this study is to determine the clinical safety and efficacy of the EndoGlide as a donor insertion device in DSAEK surgery. The investigators hypotheses is that the Endoglide will cause less endothelial damage compared to the investigators previous technique of glide insertion but will have the same low complication rate as the previous device. Hence the investigators aim to evaluate the surgical efficacy of the EndoGlide to enable consistent double coiling of the donor lenticule in DSAEK surgery with minimal endothelial touch. Evaluate ease of insertion of the EndoGlide through a 4 to 4.5mm scleral tunnel wound. Evaluate ability of the EndoGlide to consistently effect complete wound sealing, so as to stabilize anterior chamber with an AC maintainer in position. Evaluate ease of donor pull-through from the EndoGlide chamber into the AC and to evaluate spontaneous uncoiling of the donor in the AC. Evaluate clinical efficacy and safety outcomes in EndoGlide assisted DSAEK surgery in study patients with corneal decompensation requiring DSAEK surgery, in terms of postoperative visual acuity, primary graft failure rate, donor dislocation rate, endothelial cell loss, and deturgescence of the host cornea and donor lenticule as measured by corneal thickness parameters with the Visante AS-OCT. The investigators will perfprm a prospective Phase II clinical trial using the EndoGlide for donor insertion in 100 corneal patients referred to the SNEC Corneal Clinics of the study investigators with moderate degrees of corneal decompensation from a variety of disorders which require DSAEK corneal transplantation surgery, with or without concurrent cataract surgery, to restore visual acuity.

A Retrospective Review of Pain and Inflammation Resolution Outcomes in Patients Who Received DEXTENZA Intracanalicular Dexamethasone (0.4 mg) Insert Prior to or Following Corneal transplant or Cataract surgery

Objective of this study is the comparative assessment of the impact of torsional and liquefaction technologies on endothelial cells (ECC), corneal edema (CCT) and corneal sensitivity (CCS) in a sample of cataract patients. Participants were recruited from the Cataract Service of the UHA in a consecutive-if-eligible basis. Eligibility criteria included diagnosis of senile cataract with stage 2 nuclear opalescence according to the Lens Opacities Classification System III (LOCS-3) grading scale [10]. By means of a custom computer randomization program all participants randomly populated two study groups according to the cataract-extraction technology used: a) Torsional group (TG) and b) Liquefaction group (LG).

The investigators conduct this study to access the effect of corneal edema (the investigators are particularly interested in those who have the clinical central corneal edema) on the variation of intraocular pressure values measured by 3 commercial-available tonometers compare to the current gold standard tonometer; Goldmann applanation tonometer.

Clinical observation to confirm the clinical safety and efficacy of ODM 5 in the treatment of corneal edema caused by Fuchs' endothelial dystrophy.

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.

A retrospective study including 22 patients who have undergone amniotic membrane transplant in our unit up till 2016. Confocal microscopy and anterior segment optical coherence tomography (ASOCT) were performed to assess the retention of amniotic membrane and to detect any corneal structural changes. Comparison was made with 5 controls who had bullous keratopathy awaiting endothelial keratoplasty.

The purpose of this study is to report the early clinical outcomes in patients undergoing Descemet's Stripping Automated Endothelial Keratoplasty (DSAEK) for corneal edema secondary to corneal endothelial cell dysfunction, and to correlate this clinical data with the latest generation of imaging modalities available for the anterior segment.
