Comparative analysis of the clinical outcomes with 2 multifocal intraocular lens models with rotational asymmetry

Abstract

To compare the clinical outcomes after cataract surgery with implantation of 2 models of a new rotationally asymmetric multifocal IOL to ascertain which provides better visual performance and patient satisfaction. Vissum Instituto Oftalmologico de Alicante, Alicante, Spain. Comparative case series. Consecutive eyes of cataract patients were divided into 2 groups. Group A received a Lentis Mplus LS-312 MF15 IOL (with a near addition [add] power of +1.50 diopters [D]) and Group B, a Lentis Mplus LS-312 MF30 IOL (with a near add power of +3.00 D). Distance, near, and intermediate visual acuity outcomes were evaluated preoperatively and postoperatively during a 6-month follow-up. Postoperative contrast sensitivity, patient satisfaction, ocular aberrations, ocular optical quality, and defocus curves were analyzed. Patients ranged in age from 55 to 83 years. Group A comprised 22 eyes and Group B, 21 eyes. Both groups had a statistically significant improvement in uncorrected and corrected distance and corrected near visual acuities postoperatively (P≤.01). Group B had statistically significantly better uncorrected and distance-corrected near visual acuity (P≤.01) and Group A, significantly better uncorrected intermediate visual acuity (P=.01) at 3 months. There were statistically significant differences between-group differences in several levels of defocus based on defocus curves. There were no significant differences in postoperative contrast sensitivity, patient satisfaction, optical quality, and ocular aberrometry between groups (P≥.07). Both IOL models restored distance visual function and improved intermediate vision. Near visual rehabilitation was complete with the +3.00 D add IOL.
