Accommodation of IOL; true of false?

Purpose: Accommodation of artificial phakic eye after IOL implantation is well known. By the classical theory of Helmholtz, it is incomprehensive and called as “false accommodation”. In the present study we used modern technique to measure the triad of near response by TriIRIS. Among the triad, accommodative stimulus is employed as a trigger and accompanying pupillary reaction with converging eye movement are recorded simultaneously on both eyes. Continuous three trials are analyzed to calculate the “accommodative contraction rate” (ACR) of pupil.
