Filter by:This is a Phase 2a, 2-part study (designated Parts A and B) that will evaluate APP13007 dose strength and dosing frequency in a randomized double-masked fashion for comparison to the respective matching vehicle placebo. Part A will be conducted first to evaluate 0.05% APP13007 and matching vehicle placebo in an approximate 1:1 ratio in approximately 42 subjects who experience postoperative inflammation on the first day following routine, uncomplicated, cataract surgery and who meet all eligibility criteria. Based on the results of Part A, Part B of the study may be open for enrollment to evaluate 0.05% and/or 0.1% APP13007 at various dosing frequency in approximately 84 subjects, also in an approximate 1:1 ratio, active vs. placebo. In each Part, subjects will return periodically for study assessments during the treatment period and then for a follow-up visit approximately 1 week after stopping the study drug.
Evaluation of the antimicrobial efficacy of a liposomal ozone-based solution (OZODROP®) , vs placebo in 200 patients undergoing cataract surgery by phacoemulsification . The clinical trial will last 3 days of treatment per patient. The conjunctival swab will be taken for each of the two eyes (in treatment and control) at T0 (before starting the treatment - 3 days before the cataract surgery) and at T3 (after 3 days of treatment - immediately before the cataract surgery). The last OZODROP instillation will take place 10 minutes before taking the sample.
Congenital cataract is the main cause of form deprivation amblyopia in children. Current studies confirm that form deprivation amblyopia affects the macular development. However, there are different opinions about the effect of amblyopia on the macular thickness . Investigators have performed "cataract extraction with IOL implantation" on children with bilateral and unilateral congenital cataract. Investigators used OCT biometry to measure children's the macular thickness before and after surgery..Average sectional total thickness was automatically determined by the instrument's software using a modified Early Treatment Diabetic Retinopathy Study (ETDRS) circle grid (fovea, inner ring, and outer ring: 1 mm, 3 mm, and 6 mm. Investigators dynamically observed changes in macular to explore the retinal mechanism of form deprivation amblyopia and help guide the clinical correct understanding of postoperative follow-up time.
Justification. Fuchs' corneal endothelial dystrophy (FECD) is one of the main causes of corneal transplantation. In many cases, the corneal decompensation derived from this dystrophy is triggered as a consequence of cataract surgery, so the dilemma of facing isolated cataract surgery or combined with endothelial keratoplasty is often raised. Objective. The present study aims to evaluate and select the most important predictive factors for corneal decompensation after cataract surgery in patients with FECD. Method. Prospective observational study of the preoperative and intraoperative variables presumably associated with postoperative corneal edema requiring Descemet stripping endothelial keratoplasty (DMEK). Consecutive candidates for cataract surgery with FECD will be selected and anterior segment imaging will be performed, along with a complete ophthalmological examination. Clinical, pachymetric, tmographic, densitometric, specular microscopy, and intraoperative variables will be registered.
Clinical trial with medical devices, post-authorization, parallel, single-blind, randomized, comparative, prospective to study how afects the quality of life the use of ocular eye drops on patients with dry eye symptomatology and age-related loss of visual acuity. Secondary purposes: efects on the dry eye symptomatology, efect on visual acuity and treatment adherence.
This study is a prospective, observational, randomized, controlled, paired eye, subject-masked design.

Primary aim of the study is to determine whether a rho kinase inhibitor, Netarsudil, can speed corneal clearance after DWEK. Secondary aim of the study is to investigate whether patient factors, such as baseline age, pachymetry, or endothelial cell count influence response to Netarsudil.
The main objective of the trial is to assess the efficacy of the CT LUCIA 611P intraocular lens (IOL) with regard to the horizontal IOL position stability. The horizontal position collected at 1 month and 4 to 6 months post-operatively will be compared to the horizontal IOL position recorded at baseline (1 week post-operatively) as well as to the position stability of the reference IOL, CT ASPHINA 409MP.
The investigators are going to Investigate the comparative efficacy of the patients who underwent cataract surgery with three different multifocal IOLs.
