Active clinical trials for "Cataract"

This study compares two FDA approved Cataract Lasers.

The purpose of this study was to evaluate total residual spherical aberration (TSA) post-IOL implantation, and to determine if an association exists between TSA, postoperative high order aberrations (HOA), and functional vision following IOL implantation in patients grouped by pre-operative corneal spherical aberration (CSA).

The objective of this study is to compare the contrast sensitivity, high and low contrast visual acuity (VA), glare meter outcomes, and subject satisfaction with three different FDA-approved intraocular lenses (IOLs) designed to improve distance, intermediate, and near vision following lens extraction in adults at least 40 years of age.

The purpose of this study is to prospectively evaluate postoperative visual and refractive parameters in a series of subjects bilaterally implanted with Presbyopia-Correcting Intraocular Lenses (IOLs).

The objective of this study is to prospectively evaluate the visual parameters in a series of patients after phacoemulsification cataract surgery in a series of patients bilaterally implanted with the AcrySof® ReSTOR® Aspheric +3.0 Intraocular Lens (IOL).

Bilateral evaluation of unilateral implantation of ReSTOR and contralateral monofocal or phakic eye.

Hypothesis : Phacoemulsification is superior to SICS with regards to: Immediate unaided high and low contrast visual performance Its impact on quality of life.

The aim of the study is to compare functional results and complications of 3 methods of cataract phacoemulsification: bimanual 1.4 mm cataract surgery (B-MICS), coaxial 1.8 mm cataract surgery (C-MICS) and coaxial 2.4 mm small incision cataract surgery.

The primary purpose of this study is to compare the Clareon/Clareon Toric Intraocular Lenses (IOLs) to the Eyhance/Eyhance Toric IOLs in binocular Best Corrected Distance Visual Acuity (BCDVA) at 3 months postoperative.

Prospective, randomised, controlled, single-surgeon, single-center clinical study to compare the clinical outcomes of two trifocal IOLs differing in the dominance of additional power. The investigational device POD L GF shows dominance for the intermediate addition (+1.75 D), whereas the control device POD F GF shows dominance for the near addition (+3.5 D). Implantation of the IOLs is bilaterally.
