Abstract Details

Purpose:

To evaluate and compare the objective visual outcomes of Technis Symfony(ZXR00) Extended Range of Vision IOL (micro-mono-vision approach) with AcrySof IQ ReSTOR MFIOL (contralateral approach).

Setting:

Advanced Eye Centre [AEC], Department of Ophthalmology, Postgraduate Institute of Medical Education and Research, Chandigarh, India. 160012

Methods:

48 eyes of 24 patients were prospectively enrolled and stratified into two groups: Technis Symfony (Group-A, n=12) and MFIOL (Group-B, n=12). Target refraction was 0.50-0.75D myopia in non dominant eye of group-A & emmetropia in rest of the eyes of group-A & all eyes of Group-B. Two different near adds(�.5D add in distance dominant eye and �.0D add in other eye) were used in Group-B. Subjective refraction, Defocus Curve (DC) and Contrast-Sensitivity (CS) were evaluated at 1st and 3rd month.

Results:

At 3 months, the mean binocular UDVA for group-A&B was 0.05 & 0.02 respectively. Binocular mean distance corrected intermediate (50 cm) acuity was 0.29 �Â�± 0.16 in group-A and 0.27 �Â�± 0.11 in group-B. Binocular mean distance corrected near (30 cm) visual acuity 0.21 �Â�± 0.06 in group-A and 0.20 �Â�± 0.01 in group-B. Both the groups maintained amean LogMAR visual acuity of 0.18 or better through a defocus level of �.0 to �.0D but group-A patients�â�€�™ maintained mean binocular LogMAR visual acuity of 0.00 from 0.0D to -1.5D defocus. Both the groups had comparable mean log contrast sensitivity values.

Conclusions:

Both the approaches provide good level of spectacle independence at all distances and have similar contrast sensitivity values and have essentially similar results subjectively as well.
