Method for intraocular lens injector assembly having shuttle assembly retaining intraocular lens in storage vial and operably presenting intraocular lens in injector assembly
A shuttle, vial and injector are provided for storing and presenting an IOL to a patient. The shuttle includes operably engaged shuttle plates having a set of confronting surfaces that flex about a flexure interface between a storage configuration, with at least an optic of an IOL in a nominal state and a loading configuration, with at least an optic of an IOL in a deformed state. The vial engages the shuttle and maintains the shuttle in the storage configuration. The injector receives the shuttle from the vial and includes surfaces for flexing the portions of the shuttle plates to the loading configuration upon engagement with the injector, wherein the shuttle plates impart a predetermined curvature to at least a portion of the IOL.
1. A method of disposing an IOL having an optic within a shuttle, the method comprising:
(a) locating an IOL on a fixture;
(b) capturing the IOL located on the fixture within an IOL chamber, the IOL chamber defined by an engaged first shuttle plate and second shuttle plate, the engaged first shuttle plate and a second shuttle plate defining a shuttle having the IOL chamber; and
(c) withdrawing the fixture from the IOL through a port in the IOL chamber to retain the IOL within the IOL chamber.
2. The method of claim 1 , further comprising retaining the IOL optic in a nominal state within the IOL chamber.
3. The method of claim 1 , further comprising engaging the shuttle with a vial, wherein the vial includes surfaces for disposing the first shuttle plate relative to the second shuttle plate in an engaged storage configuration, wherein the IOL is retained in a nominal state within the IOL chamber.
4. A method of removing a loaded shuttle retaining an IOL having an optic from a vial, the method comprising:
(a) opening the vial retaining sterile solution and the loaded shuttle operably engaged with the vial, the loaded shuttle having a first shuttle plate coupled to a second shuttle plate, and moveable between a coupled storage configuration and a coupled loading configuration, the coupled first shuttle plate and the second shuttle plate defining an IOL chamber retaining the IOL, the vial configured to flex the first shuttle plate and the second shuttle plate about a flexure interface to dispose the first shuttle plate and the second shuttle plate in the coupled storage configuration retaining the optic in a nominal state within the IOL chamber; and
(b) removing the loaded shuttle from operable engagement with the vial, wherein the shuttle is moved to the coupled loading configuration to impart a predetermined deformation of the optic.
5. A method of packaging an IOL, the method comprising:
(a) capturing an IOL within an IOL chamber formed by an operably coupled first shuttle plate and second shuttle plate to provide a loaded shuttle, the first shuttle plate and the second shuttle plate moveable between a coupled storage configuration and a coupled loading configuration;
(b) engaging the loaded shuttle with wedging surfaces of a vial to dispose the loaded shuttle in the coupled storage configuration, wherein the IOL chamber retains the IOL in a nominal state; and
(c) sterilizing the loaded shuttle in the vial.
6. A method for presenting an IOL to a patient, the method comprising:
(a) disengaging a loaded shuttle in a coupled storage configuration from a vial, the loaded shuttle having the IOL retained in an IOL chamber; and
(b) loading the loaded shuttle into an injector to transition the loaded shuttle from the coupled storage configuration to a coupled loading configuration, wherein the loaded shuttle includes a first shuttle plate and a second shuttle plate that flex about a flexure interface to simultaneously abut a storage set of confronting surfaces and a loading set of confronting surfaces of the first shuttle plate and the second shuttle plate, wherein the flexure interface is intermediate the storage set of confronting surfaces and the loading set of confronting surfaces and the coupled loading configuration of the loaded shuttle reduces a dimension of the IOL chamber and imparts a predetermined curvature of the IOL, the predetermined curvature inhibiting movement of the IOL along a shuttle lumen in the loaded shuttle.
7. The method of claim 6 , wherein disengaging the loaded shuttle from the vial, includes disengaging the loaded shuttle from a coupled storage configuration wherein the IOL chamber retains the IOL in a nominal state.
