Prospective Evaluation of the Long-term Effectiveness of the Femtosecond Laser-assisted Arcuate Incisions

The purpose of this prospective post-market-clinical-follow-up study is to address the long-term effectiveness of arcuate incisions, in eyes after VICTUS femtosecond laser-assisted astigmatic keratotomy. This study will be conducted at Gemini eye clinic in Zlin, Czech Republic by Dr. Pavel Stodulka who will examine up to 100 eyes who previously ...

Phase N/A

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 ...

Advanced Surface Ablation (ASA) vs Laser-Assisted In Situ Keratomileusis (LASIK)

Excimer laser vision correction (LVC) is a widely used procedure to correct nearsightedness, farsightedness, and astigmatism by reshaping the surface of the eye (cornea). Laser-Assisted In Situ Keratomileusis (LASIK) and Advanced Surface Ablation (ASA) and are techniques currently used to prepare the cornea for Excimer LVC. This review is intended ...

Compare Anterior Chamber Biometry in Healthy and Post-LASIK Patients

Accommodation is an action that enables projections of both distant and near objects to be brought into clear focus on the retina through changing of diopteric power of crystalline lens. Although the exact mechanism of accommodation remains inconclusive, most authors agree that contraction of ciliary muscle plays a pivotal role.1, ...

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 ...
