Implantation of intraocular lenses (IOLs) is a possibility to treat presbyopia.The two main lines are represented by multifocal („pseudoaccommodating”) and socalled accommodating intraocular lens designs.This prospective, randomized study included 19 eyes of 11 patients (4 men, 8 women).All patients underwent a thorough discussion with the surgeon about the risks, benefits, and alternatives of the treatment.Possible mechanisms that may contribute to presbyopia include decreased elasticity of the crystalline lens, alterations in the elastic layer of Bruch’s membrane, fibrotic changes in ciliary muscle thickness, changes in the vitreous body and circumferential enlargement of the crystalline lens (1).The accommodative amplitude begins to decrease already in childhood, whereas symptoms typically appear around the ages of 40-45 (2).A Scheimpflug imaging system (Pentacam; Oculus Optikgeräte Gmb H, Wetzlar, Germany) was used to evaluate IOL tilt and decentration according to de Castro et al (10) as follows: IOL decentration is obtained from the distance between the IOL center and pupillary axis.

Decreased accommodative ability arises not only from anatomical but physiological aberration as well.Worth, TX) five times daily for 1 week and four times daily for the following week.Six months postoperatively, we measured uncorrected and spectacle-corrected distance, intermediate and near visual acuity.The study was conducted in compliance with the Declaration of Helsinki and was approved by the local Ethics Committee.Inclusion criteria were senile cataract and age 50 years or older.
