Post-Approval Study of the TECNIS Toric Extended Cylinder Range Intraocular Lens (IOL)

Post-Approval study to evaluate the rates of severe visual distortions for patients requiring correction of approximately 3.00 D to 4.75 D of corneal astigmatism.

Phase

Intrastromal Correction of Ametropia by a Femtosecond Laser

This study evaluates the intrastromal correction of ametropia with a femtosecond laser made by 20/10 PERFECT VISION. This laser generates a beam of ultrashort, infrared pulses which enables very precise cuts in the cornea. By these cuts lamellae of the cornea are separated locally, and in the consequence the curvature ...

Phase

Pseudophakic Astigmatic Reduction With Verion-LenSx Arcuate Incisions

The purpose of this study is to evaluate the effectiveness of corneal arcuate incisions when they are performed with a femtosecond laser system on subjects who have had previous cataract surgery. The procedure to be used would not be different from that employed during cataract surgery, except that the only ...

Evaluating and Improving Functional Driving Vision of Patients With Astigmatism: Phase 3

The purpose of this randomized control trial is to compare visual performance and simulated driving performance of adults with astigmatism when wearing 1*DAY ACUVUE® MOIST for ASTIGMATISM (toric), 1*DAY ACUVUE® MOIST (spherical control), and 1*DAY ACUVUE® MOIST (placebo) contact lenses. Adult subjects with nearsightedness and astigmatism will wear three types ...
