During the surgery the cloudy lens is removed and replaced with a clear plastic lens in the same lens capsule as the natural lens.

Institute of Vision and Optics (IVO), University of Crete, Medical School, Heraklion, 71003 Crete, Greece Received 7 March 2011; Revised 5 July 2011; Accepted 12 July 2011Academic Editor: Rupert M. In the attempt to manage presbyopia, different intraocular lens designs have been proposed such as monofocal IOLs with monovision or multifocal IOLs.

Even though the lenses mentioned offer satisfactory visual results, contemporary ophthalmology has not completely answered the presbyopic dilemma by simulating the accommodative properties of the crystalline lens itself.

The restoration of near vision in older individuals that have entered the presbyopic age is considered one of the major challenges in refractive surgery during the last decade.

There are three principal approaches for the achievement of good near and far vision concomitantly.

All eyes had best corrected distance visual acuity of 20/40 or better, and 19 eyes (79%) had an uncorrected distance visual acuity of 20/40 or better.And though they cannot mimic the precision of the human crystalline lens, these IOLs continue to evolve, as manufacturers enhance them to offer patients the potential of largely spectacle-free lives.The newest versions of premium IOLs have improved over their predecessors, according to Bonnie A. “The changes for the new generation of the IOLs are based on patient outcomes and feedback the companies receive from surgeons.A cataract is a condition which causes clouding of the natural lens of the eye, resulting in blurring or glaring of vision.Surgery is the only treatment for cataracts and is recommended based on the severity of the disease and the impact on the daily activities of the patient.

A prospective noncomparative case series with retrospective control comprised 21 patients (26 eyes) scheduled for small-incision extracapsular cataract extraction by phacoemulsification with implantation of the Synchrony dual-optic accommodating IOL (Visiogen) (accommodating IOL group) and 10 patients who had small-incision extracapsular phacoemulsification with implantation of a monofocal, single-optic IOL at least 6 months previously (control group).
