[Clinical Results of the Implantation of Two Types of Multifocal Rotational Asymmetric Intraocular Lenses]

The aim of the study was evaluation and comparison of clinical results of two types of rotationally asymmetric multifocal intraocular lens (LENTIS Mplus and LENTIS MplusX).

The study included 247 eyes of 124 patients aged 25 - 76 years (mean, 58 years). After phacoemulsification multifocal intraocular lens LENTIS Mplus (group A, n = 141) or LENTIS MplusX (group B, n = 106) was implanted. Patients were divided into two groups according to the type of intraocular lens. Patients were evaluated at 1 month, 3 months and 6 months after surgery. We assessed the uncorrected visual acuity, best corrected visual acuity, subjective refraction, contrast sensitivity and subjective satisfaction.

Mean preoperative monocular uncorrected distance visual acuity (UCDVA) in the group A was 0,40 ± 0,27; in the group B 0,34 ± 0,25. Postoperatively UCDVA was statistically significant improved in both groups (group A: 1,01 ± 0,20; group B: 0,90 ± 0,15). Mean preoperative monocular uncorrected near visual acuity (UCNVA) was Jaeger (J) 12,82 ± 4,16 (group A), resp. J 12,73 ± 3,99 (group B). Postoperatively UCNVA was statistically significant improved in both groups (group A: J 1,81 ± 1,42; group B: J 1,54 ± 1,72). There was not found statistically significant difference between both groups in these parameters. Contrast sensitivity was evaluated in patients who have undergone clear lens extraction in both eyes. There was not found the statistically significant reduction of contrast sensitivity in both groups. Subjective satisfaction was assessed in the range of marks 1-5. The average mark of the subjective satisfaction ratings in the group A was 1,37; in the group B 1,25.

Our study found the multifocal intraocular lens LENTIS Mplus and LENTIS MplusX give high-quality distance and near vision and provide high degree of spectacle independence. There was not found statistically significant difference in all parameters between the Group A (implantation Mplus LENTIS) and the Group B (implantation LENTIS MplusX) in our study. However, in our study we have observed higher subjective satisfaction and lower incidence of optical phenomena in the Group of patients with the implantation of intraocular lens LENTIS MplusX.Key words: LENTIS Mplus, LENTIS MplusX, visual acuity, contrast sensitivity, optical phenomen.
