Purpose: The efficacy and safety of tinted aspheric multifocal toric intraocular lens (IOL) (SND1T3, SND1T4, SND1T5, SND1T6: Alcon) were evaluated in 130 eyes of 65 patients following cataract removal.
Methods: Visual acuities (VAs) at distance, near (40 cm) and intermediate (50 cm, 1 m), IOL rotation, contrast sensitivity, spectacle usage and glare/halo were examined up to 1 year postoperatively.
Results: The mean bilateral uncorrected distance VA was -0.04±0.10 logMAR, near VA was 0.00±0.11 logMAR, intermediate VA at 50 cm was -0.00±0.11 logMAR, intermediate VA at 1 m was 0.11±0.15 logMAR. IOL rotation was 5.73±4.36 degrees, photopic contrast sensitivities were within normal range, and 76.9% of the patients did not require any spectacles. None of the patients complained of either serious glare or halo.
Conclusion: The multifocal toric IOL provides better VA from distance to near at 40 cm.
