Abstract
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.
