Abstract

Abstract The invention provides an improved autoclavable system for packaging of intraocular lens structures. In one embodied form, the inventive system comprises an outer container having at least two optically clear windows arranged in parallel relationship, an inner holding fixture mounted within the outer container for receiving and supporting an intraocular lens structure in alignment with the windows and a liquid medium within the container which substantially duplicates optical transmission characteristics of fluid in the eye. The unique packaging system provides an autoclavable sterile environment for a wide variety of intraocular lens structures prior to implantation which permits visual inspection and measurement of important optical parameters of the lens structure without removal of the lens from the container. Additionally, in a preferred embodiment of the invention, the lens holding fixture can also be used as a surgical tool and handling device for the intraocular lens during manufacture, inspection prior to implantation, and manipulation for placement of the intraocular lens structure within the eye.

Claims Analysis

Total Claims: 24
Claim 1
Independent Claim 220 words
An improved autoclavable system for packaging of an intraocular lens structure having a peripheral lens portion and an optical zone lens portion for implantation within a human eye, said system comprising, in combination: (a) an outer container having at least two optically clear windows arranged in substantially parallel relationship with one another; (b) means for sealing and for maintaining a sterile environment within said outer container; (c) means for receiving and for supporting said intraocular lens structure mounted within said outer container, said means integrating with said peripheral lens portion of said intraocular lens structure but maintaining said optical zone portion of said intraocular lens structure in a substantially complete visually unobstructed fashion aligned with said outer container windows thereby enabling the intraocular lens structure to be inspected from said outer container windows for prescribed optical parameters of said intraocular lens structure including type, size, configuration, optical finish and diopter power of said lens structure; and (d) a fluid medium within said outer container having appropriate optical transmission characteristics, wherein said system for packaging said intraocular lens structure affords measurement of said optical parameters of said lens structure in an environment substantially similar to the expected environment of said lens structure once implanted in the eye while maintaining a sterile environment for the lens structure within said system for packaging.
Claim 2
Dependent Claim 220 words
An improved autoclavable system for packaging of an intraocular lens structure having a peripheral lens portion and an optical zone lens portion for implantation within a human eye, said system comprising, in combination: (a) an outer container having at least two optically clear windows arranged in substantially parallel relationship with one another; (b) means for sealing and for maintaining a sterile environment within said outer container; (c) means for receiving and for supporting said intraocular lens structure mounted within said outer container, said means integrating with said peripheral lens portion of said intraocular lens structure but maintaining said optical zone portion of said intraocular lens structure in a substantially complete visually unobstructed fashion aligned with said outer container windows thereby enabling the intraocular lens structure to be inspected from said outer container windows for prescribed optical parameters of said intraocular lens structure including type, size, configuration, optical finish and diopter power of said lens structure; and (d) a fluid medium within said outer container having appropriate optical transmission characteristics, wherein said system for packaging said intraocular lens structure affords measurement of said optical parameters of said lens structure in an environment substantially similar to the expected environment of said lens structure once implanted in the eye while maintaining a sterile environment for the lens structure within said system for packaging.
