17 Clinical Trials for Various Conditions
This is a randomized controlled trial that seeks to examine the effectiveness of Eyeprotx™ protective goggles in comparison to traditional methods against ocular injury that can occur perioperatively under general anesthesia.
STUDY OBJECTIVE: To evaluate the safety and efficacy of Acuvail 0.45% administered BID for increasing corneal re-epithelialization, decreasing the time to zero pain in post-photorefractive keratectomy (PRK) surgery, and PRK enhancement assessment at 6 months post op CLINICAL HYPOTHESES: Acuvail 0.45% administered twice daily is superior to Systane Ultra lubricant in treating post PRK pain OVERAL STUDY DESIGN: Structure: Single-center, randomized, open label, contralateral (one eye receives Acuvail, one eye Systane Ultra) Treatment Group: Patients will be randomized to the eye that will receive Acuvail 0.45% Assignment: Acuvail 0.45% in one eye, Systane Ultra in contralateral eye Duration: 6.5 months Controls: Systane Ultra preservative-free lubricant Dosage/Dose Regimen: Study medication will be administered to the randomized eye through post op days 1-2 BID Visit Schedule: Screening (baseline), Day 2-30 (Surgery), post surgery Day 1 and each day through corneal re-epithelialization, post surgery months 1, 3, and 6. Number of Patients: 10 (20 eyes) Condition/Disease: patients undergoing bilateral PRK surgery
The purpose of this study is to evaluate the effect of ProKera on corneal wound healing after photorefractive keratectomy (PRK) in terms of re-epithelialization, pain, adverse effects, visual recovery, refractive accuracy, and corneal clarity.
EYEdeal Scanning Technology enables rapid measurement of corneal and scleral topography. By accurately measuring the ocular surface with this imaging technology, the current iterative fitting method required to fit PROSE (prosthetic replacement of the ocular surface ecosystem) devices could be replaced and/or strengthened with a more rapid, automated fitting sequence. This could considerably reduce the time needed per visit, the number of visits, and the number of devices needed to be manufactured to reach the endpoint. Additionally, the scanning technology may afford the opportunity to successfully fit some pathology that were previously treatment failures. The automated technology may as well reduce the intensive clinician training time needed to fit PROSE devices, therefore increasing the availability and access to patients. The goal of this research is to evaluate the reliability and efficacy of this automated technology for fitting PROSE devices. Data from real-time measurement of the human eye ocular surface topography will be used to fabricate a prosthetic lens. The fit of the PROSE device will be evaluated, as well as the subjective comfort of the fit.
Prospective, open label, single arm, First in Human (FIH) clinical study to assess safety and efficacy of the CorNeat Keratoprosthesis, a synthetic cornea, for the treatment of corneal blindness
This study will evaluate the safety, tolerability and pharmacokinetics of USB005 (aclerastide) Ophthalmic Solution.
The main aim of the study is to determine the safety and feasibility of a cultivated autologous limbal epithelial cell (CALEC) transplantation in the treatment of limbal stem cell deficiency.
As a consequence of damage to multiple organ systems throughout the course of their disease, diabetic patients suffer a number of chronic complications giving rise to increased morbidity, mortality, and health care costs specific to this population. Within the ophthalmic domain, diabetic retinopathy (DR) frequently induces serious visual impairment. Although DR can be addressed surgically, surgery remains a less than ideal intervention within this population with a well-characterized compromised ability to heal. The introduction of a therapeutic agent that could accelerate wound closure and decrease healing time, thereby reducing the risk and incidence of infection and corneal scarring in these susceptible patients, would represent a significant clinical and pharmacoeconomic advance in the treatment of this condition.
The purpose of this study is to assess visual quality of patients with non-penetrating, non-metallic, stable corneal foreign bodies. Visual quality will be assessed by examining visual acuity, wavefront analysis and contrast sensitivity. Drawings, photographs, and confocal microscopy will be used to document clinical examination of the cornea at baseline and on follow-up examinations.
This is a prospective, randomized (Reading Center), masked, controlled study in up to 45 subjects who have undergone bilateral PRK with epithelial removal using alcohol in a 9.0 mm well or trephine at the time of surgery to ensure consistency of the size of the ablation area.
The purpose of this study is to look at the ability of Viscoat to ensure proper wound closure.
This study will enroll participants with a non-infected, corneal persistent epithelial defect (PED) resulting from an ocular chemical and/or thermal ocular injury which is non-responsive or refractory to current standard of care for at least 14 days. It will assess the efficacy and safety of Nexagon® (lufepirsen) plus standard of care versus NEXAGON-vehicle (placebo) plus standard of care. The recovery of the corneal epithelium will be the primary outcome measure, defined as a cornea that re-epithelializes by Day 28 of treatment and remains re-epithelialized for at least a further 28 days.
Two percent of all patients presenting to the Emergency Departments have complaints involving the eye. Corneal abrasions are a common diagnosis with patients with eye pain and often cause significant discomfort. Current treatment includes a thorough evaluation of the eye followed by patching, empiric antibiotics, cycloplegics and oral pain medicines. This study will be a randomized controlled trial to determine the safety and efficacy of BCLs. It will involve the initial patient evaluation followed by a return visit to the Emergency Department within 36 hours for re-examination. At each visit, the patient will be assessed for the size and location of the abrasion along with their report of pain using a visual analog scale. Data will be recorded on a standard data collection sheet. Telephone contact will be made at 30 days to ensure resolution of abrasion and that no complications ensued.
The purpose of this study is to identify the incidence of scratches on the surface of the eye in children who cannot blink due to medication use and to identify how best to reduce the risk of a scratch on the surface of the eye when patients are using specific medicines.
The purpose of the pilot study is to test the efficacy and safety of riboflavin/Ultraviolet A (UVA) cross-linked human donor corneas as carriers for the Boston Keratoprosthesis (Boston KPro) in patients with higher risk for corneal melting (keratolysis).
GenTeal gel is an artificial tear gel used to lubricate the surface of the eye. This study will evaluate the effect of GenTeal gel on comfort following LASIK surgery. Participants will be asked to come to the clinic for three regularly scheduled visits after LASIK surgery: Day 1 (one day after LASIK surgery), Day 7 (one week follow-up), and Day 30 (one month follow-up). Participants will be asked to complete a questionnaire regarding eye comfort during each follow up visit. Participants will be randomly assigned to one of two groups, one of which will receive Genteal Gel four times a day for five days prior to surgery. The other group will receive no preoperative gel or lubricant, which has been our standard approach for many years.
