Abstract

Purpose: : The aim of this study is to: (1) present for evaluation retinal images taken through three commercially available intraocular lenses (IOL’s), and (2) experimentally measure the add power of each IOL.

Methods: : The AcrySofTM ReSTORTM, ReZoomTM and TecnisTM multifocal IOL’s were tested on an optical imaging bench with a new 43D model eye. Images of a USAF 1951 target were taken through each IOL at object distances ranging from infinity to 286 mm. For each lens, the CCD camera was first focused at infinity. The object was then moved closer to the lens until the best near focus was achieved. Finally the add-power for each lens was estimated.

Results: : The published add power of the AcrySofTM ReSTORTM, ReZoomTM and TecnisTM multifocal IOL’s is 4.0D, 3.5D and 4.0D, respectively. As tested through the new 43D model eye the measured add power of the AcrySofTM ReSTORTM, ReZoomTM and TecnisTM multifocal IOL’s is 2.5D, 2.25D and 2.5D, respectively. All lenses show the typical primary focused image at infinity and the secondary image with a near object, without any physical refocusing of the CCD camera. The difference between the published add- powers and the measured add-powers is due to interaction of the IOL power with the corneal power.
