The CATALYS TM Precision Laser System is indicated for use in patients undergoing cataract surgery for removal of the crystalline lens. The Catalys scans the entire cornea and the lens within the pupil to create a 3D image of the eye that is automatically analyzed and then displayed as an axial and a sagittal cross-section through the center of the lens. "They did not look at things like epithelial cell loss that can have a long-term effect," he told Medscape Medical News. Rates of refractive error were not statistically different in the three treatment groups.

Cataract surgery, also called lens replacement surgery, is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification, which is referred to as a cataract, and its replacement with an intraocular lens.Metabolic changes of the crystalline lens fibers over time lead to the development of the cataract, causing impairment or loss of vision. This technique allows for accurate, gentle incisions for cataract removal. Reviewed By: J Kevin McKinney MD. SAN DIEGO — Refractive outcomes and the difference in best corrected visual acuity in patients treated with conventional cataract surgery are not significantly different than those in patients treated with femtosecond laser-assisted surgery, a new study shows. During traditional cataract surgery, cataract surgeons use a small blade to enter the front of the eye and another instrument to make a circular incision on the lens capsule to reach the cataract. Refractive Outcomes in Patients With Toric Intraocular Lenses. Refractive Outcomes in the Three Surgery Groups. LensAR. There are 4 femtosecond laser cataract surgery platforms currently available: Catalys, LenSx, LensAR (LensAR Inc.), and Victus. Fewer patients treated with conventional than with the laser surgery attained vision of at least 20/20 (62% vs 100%) or at least 20/40 (80% vs 98%), but the difference in best corrected visual acuity was not significantly different. Patients with toric lenses were excluded from the analysis. 2 years ago. You've successfully added to your alerts.
