To compare visual performance and higher-order aberrations of patients implanted with a rotationally asymmetric multifocal intraocular lens (IOL) and a diffractive multifocal IOL.
Asan Medical Center, Ulsan College of Medicine, Seoul in Korea
Twenty patients (21 eyes) with implantation of a rotationally asymmetric multifocal IOL (Lentis Mplus LS-312) and 21 patients (24 eyes) with implantation of a diffractive mulitifocal IOL (Tecnis® ZMB00) were evaluated. After 1 month postoperatively, 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.
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 0.69±0.17 and 0.26±0.06 (p<0.01), spherical aberration was 0.24±0.12 and 0.00±0.04 (p<0.01), and vertical coma was -0.27±0.33 and -0.04±0.07 (p<0.01), respectively.
The rotationally asymmetric multifocal IOL significantly increased HOAs, spherical aberration and vertical coma. However, both rotationally asymmetric and diffractive multifocal IOLs showed good visual performance at all distance.
