Clinical Trial to Evaluate the Model SC9 IOL Compared to the Model LI61SE IOL (Bausch & Lomb)

Subjects will be randomized to one of two groups. Group A, (Test Lens, Model SC9) or Group B, (Control Lens, Model LI61SE, Bausch and Lomb). Both groups will be randomized to receive either unilateral or bilateral implantation. No bilateral implantation is allowed in Phase 1. (50 subjects). Subjects will be ...

Phase N/A

Two Different Cataract Surgical Procedures to Prevent Posterior Capsule Opacification

A prospective, randomized controlled study of 240 eligible patients will been enrolled. Two eyes of each patient were assigned randomly to two groups respectively: Group I; anterior lens capsule is conventionally not reserved after continuous curvilinear capsulorhexis, while in Group II, anterior lens capsule is innovatively reserved and attached onto ...

Phase N/A

Non-genetic Risk Factors of Congenital Cataracts

Prevention and treatment of the reversible childhood blindness, including congenital cataracts (CC), has been listed as a significant component of the international programme "VISION 2020 - the Right to Sight" launched by WHO in 1999. However, there is still a lot of unsolved problems regarding to CC, especially in developing ...

Phase N/A

Morphologic and Biometric Characteristics of Preexisting Posterior Capsule Defects in Congenital Cataracts During the First Year of Life

This retrospective study reviewed infants (1 years old) with CC who were undergoing cataract extraction without IOL implantation at the Eye Hospital of Wenzhou Medical University, Hangzhou, China. CC patients with preexisting PCDs were placed in Study group, while CC patients with intact posterior capsule were included as controls. The ...

Phase N/A

Neural Compensation Visual Function and Visual Quality After Monofocal or Multifocal Intraocular Lens Implantation

Cataract extraction and intraocular lens (IOL) implantation are the current standard treatments for age-related cataract (ARC). Cataract surgery increases visual acuity but may lead to complaints after surgery. Multifocal intraocular lenses (MIOLs) provide enhanced far and near visual acuity, but they can bring about halos and glare, which are caused ...

Phase N/A

Evaluation of Cataract Surgery Outcome

The purpose of this study is to evaluate the visual outcome of the cataract surgery, including best uncorrected and corrected visual acuity, spherical equivalent, wavefront aberration and other measurements.

Phase N/A

Validation of Mesopic and Photopic Contrast Vision Tests With Respect to Nighttime Driving Ability

Subjects and Methods Adult patients with a distant binocular visual acuity of 0.8 ( 16/20; habitual correction) and healthy control subjects will be included in this explorative study after informed consent. The study will be subdivided in the following (three) parts: Part 1: Validation of the Aalen driving simulator set-up ...

Phase N/A

Clinical Study to Compare Visual Performance of Two Trifocal IOLs

This is a prospective, randomised, controlled, single-surgeon, single-center post-market clinical follow up study whereby patients undergoing routine cataract surgery will have bilateral implantation of trifocal intraocular lenses. The patients will either be implanted with the hydrophobic IOL FineVision POD F GF or the hydrophilic IOL FineVision Pod F. The primary ...

Phase N/A

Comparison of Femtosecond Laser Assisted Cataract Surgery to Conventional Phacoemulsification Cataract Surgery

This study will only include patients who are eligible to undergo cataract surgery. All patients will receive treatment that is FDA approved for cataract surgery. Because all study participants will have been scheduled for elective cataract extraction regardless of their participation in this study, there will be little or no ...

Phase N/A

Influence of Posterior Vitreous Detachment on Retinal Detachment After Lens Surgery in Myopic Eyes

Phacoemulsification with implantation of posterior chamber lenses represents the gold standard of care for patients needing lens surgery, but there is an increased risk of developing pseudophakic retinal detachment after surgery. Especially myopic patients have an even higher risk of pseudophakic retinal detachment compared to the general population. The aim ...
