Abstract Details


To assess visual outcomes, safety, predictability, and patient satisfaction with the new refractive rotational asymmetric multifocal IOL after refractive lens exchange.


Eye and Laser institute, Port Elizabeth, South Africa


Fifty eyes of 25 patients that underwent bilateral refractive lens exchange with SBL-3 lens (Lenstec, Barbados Inc.) were evaluated. The mean preoperative refractive sphere was +2.26 ± 1.91 D (range -3.25 D to +4.75 D) and the mean cylinder -0.47 ± 0.56 D (range -1.75 to 0.00 D). At three months postoperatively, near, intermediate and distance visual acuity were measured monocularly and binocularly - uncorrected and with the best distance correction. Additionally, defocus curve, Pelli-Robson contrast sensitivity and patient satisfaction were evaluated.


At 3 months, 90% eyes were within ± 0.50 D of emmetropia. The mean postoperative UDVA was -0.01 ± 0.07 logMAR monocularly and -0.05 ± 0.06 logMAR binocularly. The mean monocular and binocular UNVA (40 cm) were 0.12 ± 0.11 logMAR and 0.08 ± 0.09 logMAR, respectively. Intermediate VA (70 cm) was 0.16 ± 0.12 logMAR monocularly and 0.13 ± 0.15 logMAR binocularly. The defocus curve showed a slight drop off for intermediate VA, but generally a good range of vision was achieved. Pelli-robson contrast sensitivity values were similar to the values expected for the age category treated in this study. No intraoperative or postoperative complications occurred during the 3 months follow-up.


The new refractive rotationally asymmetric IOL provided good range of vision for near, intermediate and distance. Long-term follow-ups are necessary to evaluate the performance of this IOL. FINANCIAL INTEREST: NONE
