• PURPOSE: To evaluate the visual and refractive outcomes of toric trifocal plate-haptic intraocular lens (IOL) implantation for presbyopia correction.

  SETTING: Ophthalmology Department, Hospital CUF Porto and Hospital de Braga, Portugal.

  METHODS: Prospective interventional case series including 30 patients who had bilateral implantation of a trifocal AT LISA tri toric 939MP multifocal IOL. Inclusion criteria were age 50 to 70 years, need for bilateral cataract extraction or refractive lens exchange, and regular corneal astigmatism from 0.75 to 5.0 D. Six-month evaluations included spherical equivalent (SE), refractive and corneal cylinder, visual acuity (VA) at various distances, defocus testing, and IOL rotation.

  RESULTS: Thirty patients (60 eyes) completed the 6-month visit. Mean SE was −0.35 ± 0.36 D at 6 months (±1.00 D in 100%). Mean refractive cylinder decreased from 1.04 ± 1.46 D to 0.45 ± 0.29 D. Mean toric IOL power implanted was 2.19 ± 0.95 D.

  Mean binocular uncorrected VA was 0.08 ± 1.09 logMAR at near (±40-50 cm), 0.02 ± 1.22 logMAR at intermediate (±70-80 cm), and 0.10 ± 0.82 logMAR at 4 meters. Mean IOL rotation was 3.50 ± 1.00 degrees. No secondary intervention for IOL repositioning was required during the study follow-up. Contrast sensitivity testing showed results within normal limits.

  CONCLUSION: Trifocal AT LISA tri toric 939MP IOLs provided excellent distance, intermediate and near visual outcomes. Predictability of the refractive results and optical performance were excellent, and all patients achieved spectacle independence.
