Abstract Details

Purpose:

to compare contrast sensitivity and visual acuity results of the eyes implanted a monoblock hydrophobic acrylic spherical or monoblock hydrophobic acrylic aspheric intraocular lens after uncomplicated phacoemulsification surgery.

Setting:

This randomized prospective study was made between 2012-2015 at Cumhuriyet University Opthalmology Department.

Methods:

60 eyes of 48 patients (Group 1:30 eyes, Group 2: 30 eyes) which has undergone uneventfull phacoemulsification surgery with implantation of a spheric(Zaraccom Focus Force Ultraflex) or aspheric(Zaraccom Focus Force Aspheric) intraocular lens in the capsular bag. The patients were examined routinely 1. day, 1. week and 1. month postoperatively. At the third month, best corrected visual acuity values were recorded and the contrast sensitivity tests at 1.5 , 3, 6, 12 and 18 cpd were examined to all patients, as photopic with glare and without glare and mesopic with glare and without glare.

Results:

Contrast sensitivity results of the aspheric group were statistically higher in mesopic 1.5, 3 and 12 cpd; mesopic with glare 1.5, 3 cpd; photopic 1.5 , 3 and 6 cpd; photopic with glare1.5 and 3 cpd.

Conclusions:

These results show that both lenses provide good level contrast sensitivity despite the aspheric lens has a better optic performance.
