NCT ID: NCT06396156 Completed - Clinical trials for Corneal Endothelial Cell Loss

Anterior Versus Posterior Artisan Intraocular Lens Fixation in Aphakic Children With Insufficient Capsular Support.

Start date: January 1, 2022
Phase: N/A
Study type: Interventional

The Artisan lens (Artisan Aphakic, Ophtec BV) is an iris- claw lens designed for implantation in children with insufficient capsular support. In spite of less surgical manipulations and a relatively shorter operation time, the procedure carries the risk of corneal endothelial cell loss or dis-enclavation, particularly in children. However, most of the studies that studied iris-claw lenses in aphakic children were retrospective evaluated only a single technique; either anterior or retropupillary fixation, or comparable to other techniques of fixation. Thus the aim of this work is to prospectively compare the 2 techniques of iris-claw lens implantation and their effects on central endothelial cell density, the anatomical and visual outcome, as well as the complications' rate.

NCT ID: NCT05724446 Recruiting - Cataracts Infantile Clinical Trials

Clobetasol Propionate Ophthalmic Nanoemulsion, 0.05% in the Treatment of Inflammation After Cataract Surgery in Pediatric Population

CLOSE-3
Start date: December 12, 2022
Phase: Phase 3
Study type: Interventional

Multicenter, randomized, evaluator-blinded clinical trial compared to Prednisolone acetate, 1% in the treatment of inflammation and pain after cataract surgery in pediatric population. This study will assess the safety of Clobetasol propionate ophthalmic nanoemulsion, 0.05% to that of Prednisolone acetate, 1% when administering one drop four times a day (QID) for 14 days followed by a tapering period of 14 days after cataract surgery.

NCT ID: NCT03812640 Recruiting - Endophthalmitis Clinical Trials

Nylon Verus Polyglactin Corneal Suture in Pediatric Cataract Surgery

Start date: January 1, 2019
Phase: N/A
Study type: Interventional

Pediatric cataract surgery requires the suturing of the corneal incision in order to maintain the integrity of the eyeball and to help avoid the trauma often caused by scratching in the postoperative period of pediatric surgeries. Traditionally, this suturing is performed using 10-0 nylon material. Because this material is non-absorbable, it must be removed under sedation in cases of complications such as suture loosening, late suture lysis, accumulation of secretion on the suture, corneal neovascularization, and corneal ulceration. The objetive of this study is to compare the rate of postoperative complications and the need for suture removal after pediatric cataract surgery in cases in which nylon (non-absorbable) sutures are used versus cases in which polyglactin (absorbable) sutures are used. This is a controlled, randomized, prospective, single-center study performed on patients undergoing pediatric cataract surgery at the Clinical Hospital of the University of Campinas (UNICAMP). The volunteers for whom cataract extraction surgery has been indicated and who have signed the ICF (or whose ICF has been signed by a parent or guardian) will undergo cataract surgery and the cornea will be sutured using a polyglactin 910 suture (Vicryl® 10-0). In the control group (Group B), the cornea will be sutured using nylon 10-0 sutures (the current routine procedure). All patients will be monitored for six months and will receive complete ophthalmological evaluations in order to determine whether they experience any suture-related complications and whether sutures must be removed under sedation. A lower incidence of complications and a less frequent need for suture removal under sedation are expected in the group receiving Vicryl® sutures.

NCT ID: NCT03016156 Recruiting - Retinoblastoma Clinical Trials

Determination of the Sensitivity and Specificity of a Smartphone Application to Detect Retinoblastoma

Start date: March 15, 2018
Phase: N/A
Study type: Interventional

This study seeks to determine whether a smartphone application called CRADLE (ComputeR Assisted Detection of LEukocoria) has the potential to improve the detection of leukocoria. There will be no impact on participants' health outcome. This study will be performed in two parts, each with a distinct cohort of patients. Part 1 will assess the feasibility of various techniques/conditions for using CRADLE within patients known to have leukocoria. Part 2 will estimate the sensitivity and specificity of CRADLE to detect leukocoria (using the techniques selected from information gathered in Part 1) as compared to an ophthalmoscope, within patients referred to the clinic for suspected leukocoria. PRIMARY OBJECTIVES: - To determine the most effective usage of a camera phone application (CRADLE) to maximize detection of leukocoria in patients with retinoblastoma, congenital cataracts, and glaucoma. - To estimate the sensitivity and specificity of a camera phone application (CRADLE) in detecting leukocoria.
