Narrative Responses:

Purpose
To compare long term visual performance and higher-order aberrations of patients implanted with a rotationally asymmetric multifocal intraocular lens (IOL) and a diffractive multifocal IOL

Methods
Twenty five patients (26 eyes) with implantation of a rotationally asymmetric multifocal IOL (Lentis Mplus LS-312) and 40 patients (44 eyes) with implantation of a diffractive mulitifocal IOL (Tecnis^® ZMB00) were evaluated. uncorrected distance (UDVA), intermediate (UIVA), and near (UNVA) visual acuities; contrast sensitivity; total higher-order aberrations(HOAs), spherical aberration, vertical coma and horizontal coma were evaluated after 1 month and 6 months postoperatively.

Results
Both multifocal IOLs showed good and comparable UDVA, UIVA, and UNVA postoperatively. There were no significant differences in visual acuity at all distance and contrast sensitivity between the 2 IOLs. In Lentis Mplus group and Tecnis multifocal group, total HOAs were 0.68±0.17 and 0.31±0.11 (p<0.01), spherical aberration was 0.23±0.11 and 0.02±0.09 (p<0.01), and vertical coma was -0.23±0.31 and 0.03±0.16 (p<0.05), respectively.

Conclusion
Both rotationally asymmetric and diffractive multifocal IOLs showed good distant, intermediate and near UCVA. Significantly higher amounts of postoperative total HOA and vertical coma were found in Rotationally Asymmetric MFIOL group. However, visual symptoms and contrast sensitivity were not different between two groups.
