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 +3.00 D and the Lentis Comfort LS-313 MF15 with near addition of 1.5 D. In this chapter, the visual outcomes and optical quality results obtained with these IOL models 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. 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. 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 0 D and −2.50 D defocus levels for the Lentis Mplus LS-313; for the Lentis Comfort, visual acuity better than 0.20 LogMAR was obtained between 0 D and −1.5 D defocus levels. Mean ocular Strehl ratio was 0.09 ± 0.03 and 0.10 ± 0.04 for the Lentis Mplus LS-313 and Lentis Comfort, respectively; mean cutoff 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 Lentis Mplus LS-313 provides better near visual outcomes and an optimal intermediate visual acuity with high stability than the C-loop haptic model. Also, the Lentis Comfort provides better intermediate visual acuity after cataract surgery than the Lentis Mplus LS-313.
