Abstract
PURPOSE: To assess visual outcomes after bilateral implantation of an apodized +3.0 diopter (D) addition power toric diffractive multifocal intraocular lens (IOL). SETTING: Five study sites in Europe and South America. DESIGN: Cohort study. METHODS: Patients had bilateral implantation of the AcrySof(®) IQ ReSTOR(®)+3.0 D toric multifocal IOL. Inclusion criteria were age from 21 to 70 years, need for bilateral cataract extraction or refractive lens exchange, and regular corneal astigmatism from 0.75 to 2.5 D. Six-month evaluations included spherical equivalent (SE), refractive and corneal cylinder, visual acuity at various distances, defocus testing, reading speed, and IOL rotation. RESULTS: Forty-four of 49 patients completed the 6-month visit. The mean SE (88 eyes) was 0.09 D ± 0.49 (SD) at 6 months (± 1.00 D in 95.2%). The mean refractive cylinder decreased from 1.07 ± 0.71 D to 0.33 ± 0.44 D (≤ 0.50 D in 78.6% and ≤ 1.00 D in 92.9%). The mean binocular uncorrected visual acuity was 0.04 ± 0.08 logMAR at preferred near (≈ 39 cm), 0.07 ± 0.09 logMAR at 40 cm, 0.09 ± 0.11 logMAR at 60 cm, and 0.05 ± 0.10 logMAR at 4 m. The mean corrected reading speed increased from 125.43 ± 33.58 words per minute (wpm) to 132.68 ± 23.69 wpm. The mean IOL rotation was 2.20 ± 4.34 degrees. CONCLUSION: Six months after implantation of the toric multifocal IOL, patients had significantly reduced SE and refractive cylinder, good visual acuity across distances, increased reading speed, and minimal IOL rotation.
