To evaluate visual acuity and quality of vision after implantation of two aspheric multifocal IOLs (MIOLs) with different additional power (SV25T0 add+2.5 D, SN6AD1 add +3.0 D).
Ophthalmology unit, Department of Neurosciences, University of Verona, Verona, Italy.
30 patients (60 eyes) undergoing bilateral phacoemulsification were divided into 2 groups of 15 (30 eyes). Each group was submitted to a post operative follow-up of 6 months during which monocular corrected distance visual acuity (CDVA) at 4m, corrected near visual acuity (CNVA) at 40 cm, and corrected intermediate visual acuity at 50, 60 and 70 cm was determined. The contrast sensibility (CS) and high order aberrations (HOA) were also evaluated.
There was no statistically significant difference in CDVA (p>0,01). The CNVA resulted better in the group implanted with the MIOL add +3.0. The MIOL add + 2.5 was more effective in CIVA and in CS. HOA resulted lower in patients implanted with the MIOL add +2.5.
Both MIOL models provide a good distance vision. The MIOL add +3.0 seems to show better performances in near vision while the MIOL add +2.5 seems to provide a better intermediate vision. A better quality of vision resulted in patients implanted with the MIOL add +2,5.
