Fort worth accommodating lens
Crystalens and Trulign Toric are premium intraocular lenses (IOLs) that correct presbyopia as well as common refractive errors, enabling an expanded range of clear vision and a decreased need for eyeglasses after cataract surgery, compared with surgery performed with conventional IOLs.
Currently, Crystalens and Trulign Toric IOLs are the only FDA-approved presbyopia-correcting IOLs for cataract surgery that improve near vision by a focusing process called accommodation.
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.
Though Crystalens and Trulign Toric accommodating IOLs provide an expanded range of clear vision compared with conventional monofocal intraocular lenses, you may still need reading glasses to comfortably see small print and perform other near vision tasks.
When the ciliary muscle contracts, the lens thickens, becoming more curved for added magnification for clear near vision.
We look forward to bringing this innovative IOL technology to eye care providers and customers in the years ahead,” Power Vision prez & CEO Barry Cheskin said in a prepared statement.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.That said, most people who choose one of these accommodating IOLs are very pleased with the greater freedom from eyeglasses they have after cataract surgery.Another type of presbyopia-correcting IOL that is an alternative to accommodative IOLs is the multifocal IOL category.
