Clinical Outcomes of Patients with Refractive Aspheric Multifocal IOL Implantation

ABSTRACT

PURPOSE: To evaluate the clinical outcomes of patients with refractive aspheric multifocal intraocular lens (IOL) (Lentis Mplus(R) LS-313) implantation. METHODS: Sixty-eight eyes of 53 patients received refractive aspheric multifocal IOL implantation. Uncorrected visual acuity (UCVA) at a long distanc, as well as intermediate and near distances were measured on the first day, after two weeks, and during the first, third and sixth months postoperatively. Optical quality was evaluated using the Optical Quality Analysis System II (OQAS II). High-order aberrations (HOA) and patient satisfaction questionnaires were evaluated at three months post-operation. RESULTS: At the six-month postoperative visit, the mean UCVA at a long, two intermediate (63 cm, 100 cm) and a near distance were 0.06 +/- 0.07, 0.18 +/- 0.14, 0.15 +/- 0.13 and 0.11 +/- 0.10 log MAR, respectively. The means of the objective scatter index, modulation transfer function (MTF) cut off value, Strehl ratio and pseudo-accommodation range measured by OQAS II were 1.20 +/- 0.69, 34.15 +/- 9.53 cdp, 0.17 +/- 0.05 and 3.09 +/- 0.25 D, respectively. HOA of 5 mm and 6 mm were each 0.61 +/- 0.14 and 1.07 +/- 0.20, respectively. Eighty-two percent of patients were satisfied with the postoperative results, and 71% of the patients reported that they would recommend the procedure to others, while 24% of patients reported moderate or severe visual disturbance at night. CONCLUSIONS: Implantation of the refractive aspheric multifocal IOLs in patients with cataracts provided excellent distant, intermediate, and near visual outcomes and high patient satisfaction as well as presbyopia correction.
