Accommodating IOL imitates the natural lens in size, geometry and design

BUDAPEST, Hungary — Preliminary results after implantation of the accommodating WIOL-CF show promise, according to Ioannis Pallikaris, MD, speaking at the winter meeting of the European Society of Cataract and Refractive Surgeons.

"The concept is that of a lens that simulates the natural lens in size, geometry and design, and therefore responds like the natural lens," he said.

The WIOL-CF (A.M.I. Care) has a large 9-mm diameter that fills the capsule, a meniscoid anterior surface and a hyperboloid posterior surface contacting the posterior capsule. Central thickness is 1.1 mm to 1.4 mm. This size is achieved after implantation of the lens through hydration of the special hydrogel material. Before implantation, it is smaller, and can be implanted through an incision that is less than 3 mm.

Due to its special design, the lens has the capability to respond with front-rear movements to the action of the ciliary body and to positive vitreous pressure. The presence of an accommodative effect could be objectively demonstrated with the WASCA wavefront system.

"I implanted 15 patients bilaterally with the WIOL-CF. Visual acuity improved both at distance and near, with 64% of the patients being able to read J1," Dr. Pallikaris said.
