Elemental analysis and cataractous human lens tissue.
Modern cataract surgery, in which the cataractous lens is removed from the eye, was introduced by Jacques Daviel in Paris in 1748.
Moreover, Catalys' proprietary lens fragmentation capability has been shown to reduce the amount of effective phacoemulsification time needed to remove the cataractous lens by up to 96 percent, providing a gentler and potentially safer procedure for patients and an enhanced experience for surgeons.
Following complete removal of the cataractous lens leaving only the capsular bag in situ, the IOL is implanted.
The fragmentation procedure, which follows a capsulotomy, uses the femtosecond laser to split the cataractous lens into sections.
Changes in phaco-emulsification techniques and equipment now mean that a cataractous lens can be removed through an incision of 2mm or less.
TECNIS([R]) Multifocal IOLs are indicated for primary implantation for the visual correction of aphakia in adult patients with and without presbyopia in whom a cataractous lens has been removed by phacoemulsification and who desire near, intermediate, and distance vision with increased spectacle independence.
About TRULIGN (TM)Toric The TRULIGN(TM) Toric posterior chamber intraocular lens is intended for primary implantation in the capsular bag of the eye for the visual correction of aphakia and postoperative refractive astigmatism secondary to removal of a cataractous lens in adult patients with or without presbyopia who desire reduction of residual refractive cylinder with increased spectacle independence and improved uncorrected near, intermediate and distance vision.
This new IOL is particularly well-suited for patients who wish to reduce their dependency on reading glasses and bifocals once their cataractous lens is removed.
