AbstractSA.15.01 Quality of vision in patients implanted with aspheric Quatrix intraocular lens (IOL) Gierek-Lapinska A., Mrukwa-Kominek E., Gierek-Ciaciura S., Ochalik K.
Department of Ophthalmology, Medical University of Silesia, Katowice Objective: To compare quality of vision in patients implanted with aspheric Quatrix (Corneal) IOL with those with conventional spherical Quatrix IOL.
Methods: 20 eyes of 12 patients were implanted with aspheric IOL and 20 eyes of 12 age matched patients were implanted with conventional Quatrix IOL by the same surgeon. Visual acuity, contrast sensitivity and aberrometry were performed preoperatively and 1 day, 7 days 1 and 3 months after surgery, and results were compared between patients with different type of the IOL.
Results: Uncorrected visual acuity (UCVA) didn't differ significantly between two groups of patients. Best corrected visual acuity (BCVA) was significantly better in patients implanted with aspheric IOL. Mesopic contrast sensitivity was also better in patients with aspheric IOL as compared to those with conventional IOL for 12 and 18 c/deg spatial frequencies. Total root-mean-square (RMS) wasnt significantly different between patents with different IOLs but Z4 coeficient (spherical aberration) was significantly lower in patients implanted with aspheric IOL.
Conclusions: Better BCVA and mesopic visual performance was achieved, and positive aberration of the cornea appeared to be well compensated in patients implanted with aspheric model of Quatrix IOL.
