Filter by:The purpose of this study is to compare effects of preoperative and postoperative use of topical ketorolac tromethamine 0.4% versus placebo in uncomplicated cataract surgery. Patients scheduled to undergo phacoemulsification will be randomized to receive either topical prednisolone acetate 1% 4 times daily (QID) plus dextran 70/hypromellose QID (placebo group) or topical prednisolone 1% QID plus ketorolac tromethamine 0.4% QID (ketorolac group) for three days preoperatively and four weeks postoperatively. The primary outcome 5 weeks after surgery will be angiographic cystoid macular edema.
This clinical trial is a prospective, randomized, controlled, multicenter, study. After informed consent is obtained, patients will be evaluated for eligibility based on glaucoma severity, eye health, and visual acuity. Following successful screening, use of all topical glaucoma medications will be stopped for a period of "washout" to establish a qualifying medication-free intraocular pressure (IOP) value. Clinical follow up will be scheduled over the course of the 24 month study, and examinations will be repeated to monitor eye health. At the 1 and 2 year follow up, those patients on ocular hypotensive medications will be instructed to washout, and then have the diurnal (IOP taken in the morning, mid-day, and afternoon in the same day) IOP evaluation. Annual follow up will occur up to 5 years. The primary effectiveness endpoint is a decrease in diurnal IOP from baseline compared to the 24 months diurnal IOP following medication washout.
Study to evaluate the safety and tolerability of PRO-155 Ophthalmic Solution 0.09 % in healthy volunteers.
The purpose of this study is to compare VIGADEXA (moxifloxacin 0.5%/dexamethasone phosphate 0.075%) ophthalmic gel to VIGADEXA (moxifloxacin 0.5%/dexamethasone phosphate 0.1%) ophthalmic solution in the prevention of postoperative inflammation and infection.
This prospective nonrandomized study comprised patients with cataract, corneal astigmatism, and motivation for spectacle independence. In all cases, a Rayner M-flex® T toric Intraocular Lens will be implanted in the capsular bag. Three months postoperatively, distance, intermediate, and near visual acuities; spherical equivalent; residual refractive astigmatism; defocus curve; and contrast sensitivity will be evaluated. A patient-satisfaction and visual phenomena questionnaire will also be administered.
Cataract surgery is known to cause loss of corneal endothelial cells. In adults, it is reported that anywhere between 2 to 15% loss of corneal endothelial cell density occurs following cataract surgery. However, no data is available regarding endothelial changes after cataract surgery with IOL implantation in pediatric eyes. The aim of this study is to prospectively observe changes in endothelial cell density, coefficient of variation and hexagonality following cataract surgery with IOL implantation in pediatric eyes.
This is a randomized multicenter study to evaluate the safety and effectiveness of ReSure Sealant compared to sutures for preventing incision leakage within the first 7 days of cataract surgery.
The purpose is to evaluate the Calhoun Vision Light Adjustable Lens (LAL) and Light Delivery Device (LDD) for reducing astigmatism and improving uncorrected vision after implantation.
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 objective of this study is to compare the efficacy and safety for the treatment of postoperative inflammation following ocular surgery for childhood cataract.
