Visual outcomes and patient satisfaction with a rotational asymmetric refractive intraocular lens for emmetropic presbyopia.

PURPOSE: To evaluate the efficacy, safety, predictability, and patient satisfaction after refractive lens exchange with a zonal refractive intraocular lens (IOL) with an inferior reading addition in emmetropic patients. SETTING: Optical Express, London, United Kingdom. DESIGN: Retrospective case series. METHODS: Emmetropic presbyopic patients who had implantation of a Lentis Mplus LS-313 MF30 IOL were evaluated. Inclusion criteria were sphere between -0.50 diopter (D) and +1.00 D with no more than 0.75 D of refractive cylinder and an uncorrected distance visual acuity (UDVA) of 6/6 or better in each eye. The main outcome measures were monocular and binocular UDVA, uncorrected near visual acuity (UNVA), corrected distance visual acuity (CDVA), and patient satisfaction. Three months data are presented. RESULTS: Four hundred forty eyes of 220 patients were evaluated. The mean monocular UDVA changed from -0.04 logMAR ± 0.06 (SD) preoperatively to -0.04 ± 0.11 logMAR postoperatively (P = .39). The mean CDVA was -0.10 ± 0.05 logMAR preoperatively and -0.09 ± 0.06 logMAR postoperatively (P = .06). At 3 months, 99.7% of eyes were within ±1.00 D of emmetropia. The mean UNVA was 0.13 ± 0.14 logMAR monocularly and 0.10 ± 0.12 logMAR binocularly. On the patient satisfaction questionnaire, 91.9% of patients said the refractive procedure improved their lives and 93.5% were willing to recommend it to friends and family. Three patients requested IOL exchange because of severe night-vision phenomena or unsatisfactory quality of vision. CONCLUSION: Refractive lens exchange with this zonal refractive IOL was safe in emmetropic presbyopic patients. FINANCIAL DISCLOSURE: Dr. Schallhorn is a consultant to Abbott Medical Optics.

Initial experience with a new refractive rotationally asymmetric multifocal intraocular lens.

PURPOSE: To assess efficacy, safety, predictability, and patient satisfaction after refractive lens exchange with a new refractive rotational asymmetric multifocal intraocular lens. METHODS: One hundred six eyes of 53 patients after bilateral refractive lens exchange with the SBL-3 lens (Lenstec, Inc., Christ Church, Barbados) implantation were evaluated. The mean preoperative refractive sphere was +1.06 ± 2.63 diopters (D) (range: -8.25 to +5.00 D) and the mean refractive cylinder was -0.51 ± 0.46 D (range: -2.00 to 0.00 D). Monocular and binocular uncorrected and corrected distance visual acuity, uncorrected and distance-corrected intermediate visual acuity, uncorrected and distance-corrected near visual acuity, defocus curve, and patient satisfaction were evaluated 3 months postoperatively. RESULTS: At 3 months, 84.9% (90 eyes) were within ±0.50 D of emmetropia. The mean postoperative uncorrected distance visual acuity was -0.03 ± 0.09 logMAR (6/6 Snellen) monocularly and -0.08 ± 0.08 logMAR (6/4.8 Snellen) binocularly. The mean monocular and binocular uncorrected near visual acuity were 0.12 ± 0.12 and 0.08 ± 0.10 logMAR (6/7.5 Snellen), respectively. Defocus curve showed a slight drop off for vergences equivalent to intermediate vision. Although some night vision phenomena were reported, overall satisfaction was high. No intraoperative or postoperative complications occurred in this study. CONCLUSIONS: The new refractive rotationally asymmetric intraocular lens provided good range of vision for near, intermediate, and distance. Long-term follow-ups are necessary to evaluate the performance of this intraocular lens.
