Purpose: To compare visual function after implantation of multifocal Lentis comfort LS-313 MF 15 (group 1) or Lentis M plus LS-313 MF 30 (group 2) intraocular lenses (IOLs).
Methods: Patients between 49 and 76 years of age who received monocular cataract surgery with multifocal IOL implantation were analyzed. Patients were evaluated preoperatively and for 5 months postoperatively for distance, intermediate, and near visual acuities, and static photopic and mesopic contrast sensitivity. A satisfaction questionnaire was administered 5 months after surgery.
Results: Group 1 comprised 21 eyes and group 2 contained 34 eyes. Both groups had a statistically significant improvement in uncorrected and corrected distance visual acuities postoperatively (p<0.01). Uncorrected visual near acuity at 40 cm was better in group 2 (1 month: p = 0.013; 5 months: p = 0.051). Uncorrected intermediate visual acuity at 70 cm was better in group 1 (1 month: p = 0.060; 5 months: p = 0.044). No significant differences in contrast sensitivity were observed between the groups. Glare and halo symptoms were better in group 1 (glare: p = 0.044; halo: p = 0.029).
Conclusions: Inferior sector-shaped, near-addition IOLs with lower add powers (+1.5 D) provide good vision over longer working distances and show fewer glare and halo symptoms.
