Abstract
The Lentis Mplus is a multifocal intraocular lens (IOL) based on the concept of refractive rotational asymmetry. There are two different models, the Lentis Mplus LS-313 with near add of +3.00D and the Lentis Comfort LS-313 MF15 with near addition of 1.5D. In this chapter, the visual outcomes and optical quality results obtained with these IOL models and their combination are explained in detail.
Forty-five eyes of 25 patients were implanted with the Lentis Mplus LS-313. Thirty-one eyes of 18 patients were implanted with the Lentis Comfort. Thirty-eight eyes of nineteen patients were included. Patients were implanted with Lentis Comfort LS-313 MF15 in the dominant eye and the Lentis Mplus LS-313M30 IOL in the non-dominant eye. Distance and near visual acuities, contrast sensitivity, defocus curve and ocular optical performance were reported.
Distance and near visual acuities improved with the surgery (p < 0.01) for both IOL models and their combination. Contrast sensitivity was within the normal range for the age sample for all spatial frequencies for both IOL models. Defocus curve provided two peaks of maximum vision at 0D and −2.50D defocus levels for the Lentis Mplus LS-313, and for the Lentis Comfort, visual acuity better than 0.20 LogMAR was obtained between 0D and −1.5D defocus levels. For the Mplus blended group, the binocular defocus curve had good near, intermediate and distance outcomes. Mean ocular Strehl ratio was 0.09 ± 0.03 and 0.10 ± 0.04 for the Lentis Mplus LS-313 and Lentis Comfort, respectively, and mean cut-off spatial frequency for the ocular MTF was 13.62 ± 6.38 and 13.44 ± 5.41 for the Lentis Mplus LS-313 and Lentis Comfort, respectively. The mean rash score for the NAVQ-10 was 27.7 ± 28.15.
The Lentis Mplus LS-313 provides good near visual outcomes and an optimal intermediate visual acuity. The Lentis Comfort provides better intermediate visual acuity after cataract surgery than the Lentis Mplus LS-313. The Mplus blended group had good near, intermediate and distance binocular visual outcomes with high patient satisfaction rate for near vision.
