To evaluate the ability of three different intraocular lenses to accommodate in patients who have previously undergone bilateral intraocular lens implantation.


This is an open-label, prospective evaluation of 30 patients; ten patients bilaterally implanted with each of the following lenses: Crystalens, Crystalens HD and Tecnis One. Accommodation measured on the COAS high definition wavefront aberrometer, which captures 75 images over 12 seconds. Additional tests include visual acuity for distance, intermediate and near, topography, pupil size, and amplitude of accommodation on pushdown test.


Although results from this study are pending, based on our earlier work we expect to demonstrate that eyes with highest apparent accommodation will have smaller pupil size and more spherical aberration present in both the wavefront and topography. Analysis of the 2.5 mm central optical zone will be performed to determine how much (if any) change occurs in the central optical zone during attempted accommodation in psuedophakic patients.


The degree of accommodation varies with each IOL. True optical power change can be identified and compared and contrasted with depth of focus, higher order aberrations and/or pupil size.
