Last December, Alcon said that it acquired Tear Film Innovations for an undisclosed amount.UT Southwestern Medical Center earned High Performing recognition for ophthalmology from U. News & World Report for 2019–20, placing us among the country’s leading hospitals for eye disease treatment and care.“We’re thrilled to officially join Alcon and its pioneering history of launching new innovation in the field of ophthalmology.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.All IOLs have a central optical zone, with peripheral "legs" (called haptics) that secure the lens implant inside the lens capsule.The primary difference between a conventional monofocal IOL and an accommodating IOL is the design of these haptics.In a normal eye (without presbyopia or cataracts), this dynamic process of accommodation adjusts the focusing power of the eye by changing the thickness of the eye's natural lens.When the ciliary muscle is relaxed, the lens flattens to enable clear distance vision.
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.As the eye ages, the lens becomes less flexible, causing the loss of near vision that is the hallmark sign of presbyopia in people over age 40.During cataract surgery, a circular opening is cut in the anterior part of the lens capsule so the surgeon can remove the eye's natural lens that has become cloudy. The peripheral and posterior portions of the lens capsule are left intact, forming a partially open "bag" that the intraocular lens is positioned within to restore focusing power to the eye.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.
