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

摘要

PURPOSE: 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. SETTING: Vissum Instituto Oftalmologico de Alicante, Alicante, Spain. DESIGN: Comparative case series. METHODS: 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. RESULTS: 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/=.07). CONCLUSIONS: Both IOL models restored distance visual function and improved intermediate vision. Near visual rehabilitation was complete with the +3.00 D add IOL.
