Further Improvement of an Intraocular Lens Holder for more physiological Measurements within a Mechanical Eye Model*

摘要

To evaluate the performance of intraocular lenses to treat cataract, an optomechanical eye model was developed. One of the most crucial components is the IOL holder, which should guarantee a physiological representation of the capsular bag and a stable position during measurement sequences. Individual holders are required due to the fact that every IOL has different geometric parameters. A method which allows obtaining the correct dimensions for the holder of a special IOL was developed and tested, by verifying the position of the IOL before and after a measurement sequence. Results of telecentric measurements and MTF measurements show that the IOL position does not change during the displacement sequence induced by the stepper motors of the eye model.
