NCT ID: NCT06219252 Recruiting - Cataract Clinical Trials

Intraoperative Aberrometry vs Conventional Intraocular Lens Calculation, a Prospective Study.

ORAVSCTRL
Start date: November 3, 2023
Phase: N/A
Study type: Interventional

the goal of this intervention study is to compare prospectively the accuracy of the power calculation between both groups, the intraoperative aberrometry (ORA) vs barrett universal II preoperative calculation (control group) . Researchers will compare ORA group vs control to see changes in spherical equivalent and uncorrected distance visual acuity

NCT ID: NCT05275764 Recruiting - Congenital Cataract Clinical Trials

Comparison of the Efficacy of Intraocular Lens Optic Capture and In-the-bag Implantation Over 1 Year in Children With Congenital Cataract

Start date: November 1, 2021
Phase:
Study type: Observational

Approximately 30 eyes with congenital cataract who underwent primary or secondary intraocular lens implantation surgery at Zhejiang Eye Hospital from March 2018 to December 2020 were enrolled. According to the implantation method of IOL, patients were devided into the optic capture group and the endocapsular group. And through the clinical parameters of postoperative best corrected visual acuity (BCVA), intraocular pressure (IOP), IOL position and whether appear visual axis opacity to compare the outcome of the 2 IOL implantation methods.

NCT ID: NCT04880018 Completed - Clinical trials for Intraocular Lens Implantation

Clinical Validation Plan of Capsular Tension Ring

CVPOCTR
Start date: May 21, 2015
Phase: N/A
Study type: Interventional

Through follow-up for 1 year or more, the safety and effectiveness of the Capsular Tension Ring produced by Eyebright Medical Technology (Beijing) Co., Ltd. were verified, which is used for intraocular lens implantation in aphakic eyes after lens extraction to maintain capsular integrity, prevent posterior capsular wrinkle and resist capsular shrinkage. The clinical validation plan will be implemented after being approved by the Ethics Committee; the trial data of all cases before the 6-month visit period will be counted, and the statistical report, summary report and sub-center summary will be issued. The summary report and sub-center summary will be submitted to the CFDA for product registration.

NCT ID: NCT03115216 Withdrawn - Cataract Clinical Trials

The Femtosecond Laser in Residency Training (FLIRT) Pilot Study

FLIRT
Start date: July 2017
Phase: N/A
Study type: Interventional

This pilot study aims to primarily assess the rate of complication of anterior vitrectomy for patients undergoing femtosecond laser-assisted (FLA) cataract extraction and intraocular lens placement (CEIOL) compared to manual CEIOL, when performed by resident physicians under direct attending supervision. In this pilot study, the investigators aim to assess what the incidence of anterior vitrectomy is for each group, in order to better understand the sample size needed to assess whether there is a difference between these two groups. Secondarily, it will gather preliminary data on safety and refractive outcomes for patients undergoing these interventions.

NCT ID: NCT01718184 Recruiting - Refractive Error Clinical Trials

Piggyback Sulcoflex Toric IOL for Correcting Refractive Error Following Corneal Transplantation

Start date: October 2012
Phase: N/A
Study type: Interventional

A prospective study to evaluate the safety and efficacy of a piggyback sulcoflex toric intraocular lens in pseudophakic patients for correcting refractive errors following corneal transplantation
