Summary: This research study is evaluating the safety and efficacy (performance) of the Bausch + Lomb enVista Beyond Hydrophobic Acrylic Extended Depth of Focus Intraocular Lens (IOL) in subjects who receive this IOL in both eyes.

Summary: This study is a single center, prospective study of cumulative dissipated energy and endothelial cells loss per phacoemulsification procedure after successful cataract surgery. Subjects will be assessed 3 months postoperatively at a single visit. Clinical evaluations will include central corneal thickness, specular microscopy, as well as measurement of visual acuities at distance.

Summary: Full-thickness macular hole (MH) is a common sight threatening macular condition with a prevalence of 3.3 per 1000 individuals. Prompt surgical repair of MH is imperative in preventing irreversible vision loss from MH as the majority of patients would experience progressive loss of central vision, often resulting in visual acuity (VA) of 20/200 or worse and the spontaneous closure rate is less tha...

Summary: The primary study objective is to compare the effectiveness of the combination of phacoemulsification with intraocular lens implant with ELIOS or competitor device in reducing IOP at 12 months postoperatively.

Summary: To review how patients report using a hyaluronate crosslinked canalicular gel placed before cataract surgery

Summary: The goal of this clinical trial is to learn which of the drugs bromfenac 0.09%, nepafenac 0.3% and diclofenac 0.1% has better efficacy in treatment and prevention of cystoid macular oedema after cataract surgery. The main questions it aims to answer are: Which of the drugs has better efficacy in macular oedema prevention? What medical problems do participants have when taking different drugs? Rese...

Summary: The goal of this clinical trial is to learn whether phacoemulsification combined with goniosynechialysis (Phaco-GSL) is as effective and safe as trabeculectomy in treating patients with primary angle-closure glaucoma. The main questions it aims to answer are: * Does Phaco-GSL provide similar or better intraocular pressure (IOP) control compared to trabeculectomy? * What are the rates of postoperat...

Summary: This is study to determine the visual performance of patients with age-related cataracts implanted in both eyes with either of two extended depth of focus intraocular lenses, the Clareon Vivity (Alcon Healthcare) or the PureSee (Johnson \& Johnson)

Summary: This is a self-controlled randomized clinical trial to investigate the effect of capsular tension ring (CTR) implantation on intraocular lens (IOL) position in cataract patients with retinitis pigmentosa(RP). Each patient will receive CTR implantation in one eye, with the fellow eye serving as control. Postoperative outcomes, including visual acuity, IOL position, and postoperative complications w...

Objective: To evaluate the efficacy of intranasal Dexmedetomidine as a premedication to control hypertension in elderly patients scheduled for cataract surgery. Secondary

Summary: This prospective multicenter observational study aims to evaluate the 5-year visual function and refractive outcomes in children undergoing surgery for congenital cataract. Key outcomes include best-corrected visual acuity, stereopsis, refractive error, and axial length growth. The study will help identify long-term trends and prognostic indicators after early cataract intervention in pediatric pa...

Summary: The purpose of this clinical study is to evaluate the surgical, refractive, and visual outcomes with implantation of an investigational intraocular lens (IOL).
