Narrative Responses:

Purpose
The evaulation of the optic performance of one-piece hydrophobic acrylic spheric monofocal and multifocal intraocular lenses by comparing the contrast sensitivity.

Methods
We included 60 eyes of 45 patients (Zaraccon Ultraflex(UF) Group:30 eyes, Zaraccom Revision(RV) Multifocal Group: 30 eyes ) who have had phacoemulsification surgery and implantation of intraocular lens in the posterior chamber between 2012-2013 at Cumhuriyet University Opthalmology Department. The patients were examined routinely 1. day, 1. week and 1. month postoperatively. At the third month, best corrected visual acuity values were recorded, after than the contrast sensitivity tests at 1,5 , 3 , 6, 12 and 18 cpd were examined to all patients, as photopic with glare-without glare and mesopic with glare–without glare with an OPTEC 6500 contrast sensitivity test device.

Results
UF group’s values were significantly higher in all spatial frequencies at test mesopic and photopik with glare and without glare 1.5 , 3, 6 , 12 cpd and mesopic with glare 18 cpd(p<0.05). All patient had 20/25 or more best corrected visiual acuity after 3 month from operation. Between two groups there weren’t any statistical significance on patient’s being eyeglasses free. (P=0.114, P>0.05)

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