Multifocal intraocular lens with a surface-embedded near section: Short-term clinical outcomes

PURPOSE: To evaluate the visual and refractive outcomes and quality of life after implantation of a multifocal intraocular lens (IOL) with a surface-embedded near section. SETTING: Private practice, United Kingdom. DESIGN: Case series. METHODS: This study comprised patients who had implantation of a Lentis Mplus multifocal IOL after phacoemulsification. The main outcome measures were refraction, uncorrected (UDVA) and corrected (CDVA) distance visual acuities (logMAR), uncorrected (UNVA) and corrected (CNVA) near visual acuities (M notation), reading speed (Radner reading chart), contrast sensitivity (Pelli-Robson), and Quality of Life Impact of Refractive Correction (QIRC) questionnaire scores. A +3.00 diopter (D) reading addition (add) IOL was placed in the nondominant eye and a +1.50 D add IOL in the dominant eye. RESULTS: The study enrolled 44 eyes of 22 patients (mean age 59.9 years). The mean values 3 months postoperatively were UDVA, 0.04 logMAR ± 0.25 (SD); contrast sensitivity, 1.57 ± 0.13 logCS; near vision, M0.75 ± 0.33 at 32 cm and M0.90 ± 0.27 at 66 cm; reading speed, 161.74 words/minute; sphere, 0.08 ± 0.58 D; astigmatism, -0.60 ± 0.50 D; CDVA, -0.08 ± 0.07 logMAR. With best correction, intermediate (66 cm) and near (32 cm) vision were M0.89 ± 0.26 and M0.74 ± 0.32, respectively. The mean binocular UNVA at the preferred viewing distance was M0.57 ± 0.18, improving to M0.54 ± 0.19 with distance correction. The mean QIRC score improved from 42.15 ± 4.66 to 51.14 ± 8.22. CONCLUSIONS: Postoperative visual acuity was good with high-level contrast sensitivity, producing significant improvement in quality of life.
