Abstract Details


To compare outcomes of 2 different models of posterior chamber phakic IOL (ICL) in correction of myopia between -1.00 and -20.00 D.


Magrabi Eye Hospital


Forty myopic patients were enrolled in the study. Each patient received an ICL with central hole (VICMO) in one eye and ICL without central hole (VICM) in the contralateral eye. The model implanted in each eye was randomized. No peripheral iridectomies were performed in the VCIMO eyes. Patients satisfaction and preference were measured with a subjective questionnaire.


There was no statistical significant difference in preoperative manifest refraction, CDVA, and ocular high order aberrations between both groups. At 6 months (follow up, 80 %); the mean UDVA (LogMar) was 0.00 in each group; 77% eyes in each group saw 0.00 (20/20) or better without correction (P<0.05); the mean ocular spherical aberration was 0.06 um in the VICMO group and 0.01 um in VICM group (P<0.05). Modulation transfer function was similar for all eyes at 6 months postoperatively (P<0.05). There was no statistically significant difference patients’ satisfaction or preference between all groups.


Peripheral iridectomies are not needed for posterior chamber Phakic IOL with central hole. At 6 months, the visual and refractive outcomes, and patients’ satisfaction were similar between both groups. Ocular spherical aberrations were statistically higher in the VICMO eyes without effect on patient satisfaction or quality of vision.
