VIENNA, Austria — A PMMA anchor device can be used to recenter and fixate the capsular bag of a subluxated crystalline lens or to reposition and fixate capsule-supported IOLs, according to one surgeon speaking here.
"Many surgeons would prefer to do a lensectomy and implant either an iris-supported anterior chamber IOL or a scleral-fixated lens. Our method allows preservation of the capsule and implantation of a regular IOL in the bag," Ehud Assia, MD, said at the European Society of Cataract and Refractive Surgeons meeting here.
The Capsular Anchor (Hanita Lenses) works like a clip that holds and fixates the capsule to the scleral wall. With the lens still in the capsule, a capsulorrhexis is performed, the anchor arms are inserted behind its margin, and the anterior capsule is dragged and fixated to the scleral wall using polypropylene sutures. Phacoemulsification with IOL implantation is then carried out in a standard manner, Dr. Assia explained.
"We have successfully treated 24 cases with this method and have a follow-up of 4 years. All of them are still stable and well-centered," he said.
In selected cases the anchor can be used to reposition and fixate capsular-supported IOLs. The adhesion of the anterior capsule and lens optic is separated using a spatula and viscodissection. A pocket is created to insert the anchor and secure it to the scleral wall.
"There's no need to exchange the lens or fixate it to iris or sclera," Dr. Assia said.
