Abstract
Modular IOL systems including a base and a lens, wherein the lens includes fixed and actuatable 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. Drug delivery capabilities and/or sensing capabilities may be incorporated into the base. Injector devices may be used to facilitate placement of the base and the lens sequentially or simultaneously into the eye.
Claims20
A device configured for insertion into an eye, the device comprising:
- a base comprising:
- an anterior section surrounding an anterior opening, wherein the anterior section has a posterior surface;
- a posterior section surrounding a posterior opening, wherein the posterior section has an anterior surface;
- an in-ward facing lateral wall extending between the anterior and the posterior sections;
- and
- a passage extending through the device from the anterior opening to the posterior opening;
- wherein a first angle is formed by an anterior end of the in-ward facing lateral wall and the posterior surface of the anterior section and a second angle is formed by a posterior end of the in-ward facing lateral wall and the anterior surface of the posterior section;
- and a lens including at least one tab configured to be received between the first angle and the second angle of the base, wherein the at least one tab has a thickness that corresponds to an anterior-posterior dimension defined by a distance between the anterior end and the posterior end of the in-ward facing lateral wall of the base.
A device configured for insertion into an eye, the device comprising:
- a base, the base comprising:
- an anterior section surrounding an anterior opening, wherein the anterior section has a posterior surface;
- a posterior section surrounding a posterior opening, wherein the posterior section has an anterior surface;
- an in-ward facing lateral wall extending between the anterior and the posterior sections;
- and
- a passage extending through the device from the anterior opening to the posterior opening;
- wherein a first angle is formed by an anterior end of the in-ward facing lateral wall and the posterior surface of the anterior section and a second angle is formed by a posterior end of the in-ward facing lateral wall and the anterior surface of the posterior section;
- and
- a lens configured for insertion into and removal from the base, the lens comprising:
- an optic portion;
- and
- at least one tab, wherein the at least one tab has a thickness that corresponds to an anterior-posterior dimension defined by a distance between the anterior end and the posterior end of the in-ward facing lateral wall of the base.
A device configured for insertion into an eye, the device comprising:
- a base, the base comprising:
- a pair of haptics;
- an anterior section surrounding an anterior opening, wherein the anterior section has a posterior surface;
- a posterior section surrounding a posterior opening, wherein the posterior section has an anterior surface;
- an in-ward facing lateral wall extending between the anterior and the posterior sections;
- a passage extending through the device from the anterior opening to the posterior opening;
- and
- an intermediate section surrounding the passage,
- wherein the intermediate section comprises a first angle formed by an anterior end of the in-ward facing lateral wall and the posterior surface of the anterior section and a second angle formed by a posterior end of the in-ward facing lateral wall and the anterior surface of the posterior section;
- and a lens configured for insertion into the base, the lens including at least one tab received in the intermediate section of the base, wherein the at least one tab has a thickness that corresponds to an anterior-posterior dimension defined by a distance between the anterior end and the posterior end of the in-ward facing lateral wall.
