Title:
ACCOMMODATIVE LENS DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/167099
Kind Code:
A3
Abstract:
The invention concerns an implant that comprises an anterior part and a posterior part extending along a longitudinal axis and having respectively an anterior (A) and a posterior pole (E) both located on axis. The anterior and posterior parts extend each radially relative to axis, on either side thereof, the anterior and posterior parts having each two portions located on both sides of axis respectively when viewed in a sagittal plane. Each portion of the anterior part has a radial extension that increases from anterior pole (A) to a point (B, B') where the anterior part ends and the posterior part begins, each portion of the posterior part having a radial extension decreasing from point (B, B') to the posterior pole (E). The outer outline of each portion of the anterior part forms a curve having a radius of curvature that is greater at anterior pole (A) than at point (B, B'). The implant is made of one or more materials that have elastic or visco-elastic and cohesive properties in a solid state such that the shear modulus is between 10 Pa and 10 kPa.
