Customizing Clinical Outcomes with Implantation of Two Diffractive Trifocal IOLs of Identical Design but Differing Light Distributions to the Far, Intermediate and Near Foci.

The two diffractive trifocal IOLs studied here may be used either bilaterally or contralaterally for the correction of presbyopia in cataract patients, providing excellent visual acuity with low levels of visual disturbances and high rates of overall spectacle independence. Bilateral Gemetric implantation resulted in slightly better distance and intermediate vision while contralateral implantation provided slightly better near vision. There was no apparent advantage to implanting the GPlus IOL bilaterally.
