VALENCIA, Spain, November 18, 2009, /Journal of Refractive
Surgery/ -- The ReSTOR multifocal intraocular lens often
used to correct both distance and near vision in adults does not
affect ability to perceive distances, according to a study
published in the Journal of Refractive Surgery.
Researchers at the University of Valencia evaluated the depth
perception of 15 patients before and after Refractive Lens
Exchange (RLE) with AcrySof ReSTOR Natural implantation in both
eyes. The ReSTOR uses multiple rings of optic power within the
lens to provide focus for objects near, intermediate, and
distant, reducing the need for reading glasses.
The study found depth perception was essentially unchanged
with the ReSTOR lens.
