Visual And Refractive Outcomes Of The Unilateral Supracor Multifocal Corneal Lasik Procedure For The Correction Of Myopia And Presbyopia;

Eye Research Center, The Five Senses Institute, Rassoul Akram Hospital, Iran University of Medical Sciences and Iranian Eye Clinic, Tehran, Iran.

This study enrolled 62 eyes of 31 patients who had bilateral femto-LASIK for the correction of myopia plus Supracor in non-dominant eyes. Monocular and binocular uncorrected (UDVA) and corrected distance visual acuity (CDVA), monocular and binocular uncorrected (UNVA) and distance-corrected near visual acuity (DCNVA) at 40 cm, central corneal power, asphericity (Q) and high order aberrations changes and complications were evaluated over 6 months.

The mean age was 48.06 ± 2.33 years (range: 45 to 54 years). The mean refractive spherical equivalent (MRSE) was -2.71D in Supracor eyes and -2.64 D in dominant eyes, that reduced to -.58 and -.05 D at 6 months respectively. Binocular UDVA was ³ 20/25 and binocular UNVA was ³Jaeger 2 at 6 months. UDVA was ³ 20/50 in non-dominant eyes at 6 months. The mean central keratometry steepening was 2.15 D. Asphericity (Q value) increased significantly in supracor eyes. The mean difference changes of total RMS and higher-order aberrations in both groups were insignificant. Ninety-five percent of these patients did not need glasses for distance and near vision.

Supracor procedure in the non-dominant eyes may improve functional near, intermediate, and distance vision without significant photic phenomena in presbyopic patients with low and moderate myopia.
