| Outline of Final Research Achievements |
To develop new accommodative intraocular lens (IOL), we analyzed mechanical characteristic of human crystalline lens and Zinn’s zonule by using computer simulation software, and investigated physical property required for new accommodative IOL. The present study showed that site for attachment of Zinn’s zonule and physical property of lens capsule cause a large change in shape of crystalline lens. As to physical property required for new accommodative IOL of curvature change type, logarithm elastic coefficient was 5.0 Pa and under. These resutls could be useful for selection of subsistent material of accommodative IOL.
