Abstract:
Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. An apparatus for delivery of a lens component into an eye may include a housing. The apparatus may further include a plunger at least partially disposed in the housing, wherein the housing comprises an elongated portion and a viscoelastic soft tip at a distal end of the elongated portion, wherein the viscoelastic soft tip has a storage modulus of about 1 megapascal (MPa) to about 300 MPa and a loss module of about 1 MPa to about 300 MPa. The apparatus may further include a drive mechanism operatively coupled to plunger and configured to cause the plunger to translate in the housing. The apparatus may further include a nozzle operatively coupled to the housing through which the plunger delivers the lens component into the eye.
