Abstract
Modular IOL systems including a base and a lens, wherein the lens includes tabs for connection to the base. The modular IOL allows for the lens to be adjusted or exchanged while leaving the base in place, either intra-operatively or post-operatively.
Claims14
A modular intraocular lens (IOL) system, comprising:
- a base, comprising:
- an anterior section surrounding an anterior opening, wherein the anterior section has an anterior end,
- a posterior section surrounding a posterior opening, wherein the posterior section has a posterior end,
- a wall extending between the anterior and the posterior sections, wherein the wall includes a radially inner surface, and wherein a ratio between:
- (a) a dimension of the base between the anterior and the posterior ends, measured along an anterior-posterior direction, and (b) a diameter of the base, is between 0.11 and 0.14,
- a passage extending through the base from the anterior opening to the posterior opening, and
- a recess surrounding the passage, wherein the recess is defined by surfaces of:
- (a) the anterior and the posterior sections, and
- (b) the radially inner surface of the wall;
- and
- a lens configured for insertion into and removal from the base, the lens comprising:
- an optic, and
- at least one tab protruding from the optic, wherein when the lens is inserted into the base, the tab is received by the recess of the base, and the optic extends across the passage of the base.
