Fort worth accommodating lens Xxx srilank
The lens and ciliary muscle are connected by a 360-degree series of fibers (called ciliary zonules) that extend from the ciliary muscle to the thin lens capsule (or "bag") that encloses the lens.
The ciliary muscle, ciliary zonules and lens capsule keep the lens suspended in its proper position inside the eye for clear vision.
Novartis (NYSE: NVS) subsidiary Alcon said today that it acquired intraocular lens developer Power Vision for 5 million.This is why they are classified as "accommodating IOLs."Both lenses are manufactured and distributed by Bausch Lomb.Accommodation is a process that enables the eye to adjust its focusing power to provide clear vision at all distances. Accommodation is made possible by the lens inside the eye and the circular muscle that surrounds the lens, called the ciliary muscle.Like multifocal contact lenses, these premium IOLs have more than one power, with added magnification in certain zones of the lens for improved near vision.Both categories or presbyopia-correcting lenses — accommodating IOLs and multifocal IOLs — have advantages and limitations.
The primary difference between these two FDA-approved accommodating IOLs is that the Trulign Toric IOL can correct astigmatism as well as nearsightedness or farsightedness.
