Abstract Details


To present a new lens design that is specifically suited to FLACS, which has become widely accepted due to it’s advantages over traditional phaco surgery with manual capsulorrhexis.

Discussion of a new lens concept that has been developed especially for use with FLACS. The lens is made from a hydrosmart material with a 25% water content, and has a 5.7 mm optical diameter within a 10.5 mm total diameter. The optic has an biconvex aberration-neutral aspheric design. The lens is fixed at the edges of the laser capsulotomy after implantation within the capsular bag.


FLACS has become widely accepted due to its advantages over traditional phaco-surgery. The use of a femstosecond laser vs. manual capsulorrhexis can guarantee a precise and reproducable capsolotomy at a given size before cataract or clear lens surgery. Femtosecondlaser assisted nucleus fragmentation can lead to a substantial reduction in ultrasound energy reducing potentially harmful energy to the corneal endothelium. The fixation of the lens within the capsulotomy may deliver a far better stabilization of the lens optic preventing any shifts or rotation.


A perfect and stable centration of the lens within the caspular bag is desirable and important for optimal visual results, especially true for aspheric IOL‘s, toric and multifocal IOL`s. The lens idea presented is the first example of a design which only can be used when performing cataract surgery with a femtosecond laser.
