Abstract
Purpose: :
To determine if differences in intraocular lens implantation will have an effect on the subjective and objective measurements of fundus characteristics using currently available imaging technology.
Methods: :
A prospective comparative trial of 50 patients undergoing intraocular lens implantation. Twenty–five patients having monofocal (AcrySof) intraocular lens implantation and 25 having diffractive/accommodative (ReSTOR) intraocular lens implantation underwent pre and post–operative imaging studies, including digital color and red–free fundus photography, fundus autofluorescence imaging, and optical coherence tomographic imaging of the macula and optic nerve fiber layer. A comparison of the pre and post–operative studies was conducted within each group and then compared between the groups to determine if changes were noted that could materially affect fundus imaging after surgery.
Results: :
Potential changes in fundus imaging parameters, both subjective and objective in nature, following cataract surgery with implantation of either a monofocal or accommodative diffractive intraocular lens will be shown.
Conclusions: :
In response to the increasing variety of types of intraocular lenses, this study provides important information in determining whether the differences in intraocular lens choice might affect the interpretation of fundus imaging and provide guidelines for physicians monitoring patients in both clinical trial and clinical practice settings.
