Tecnis multifocal toric IOL can provide improved distance and near visual acuities

Issue: October 10, 2016

Patients who underwent cataract surgery with implantation of a diffractive multifocal toric IOL tended to experience “excellent” distance and near visual acuities with good intermediate visual acuity after the procedure, according to a study.

Researchers included 60 eyes of 30 patients with cataract and regular corneal astigmatism who had phacoemulsification with bilateral implantation of the Tecnis multifocal toric ZMT 150, 225, 300 or 400 IOL (Abbott Medical Optics) in a prospective study.

Patients were followed for 6 months, and no eyes were excluded from the final results due to complications. At 6 months, uncorrected distance visual acuity was at least 0.3 logMAR (Snellen 20/40) in all eyes and at least 0.1 logMAR (Snellen 20/25) in 25 eyes.

Uncorrected intermediate visual acuity at 80 cm as at least 0.3 logMAR (Snellen 20/40) in 22 eyes and at least 0.1 logMAR (Snellen 20/25) in 20 eyes. Uncorrected near visual acuity at 40 cm was at least 0.3 logMAR (Snellen 20/40) in all eyes and at least 0.1 logMAR (Snellen 20/25) in 27 eyes.

All eyes gained lines of corrected distance visual acuity by the 6-month follow-up. No patients reported using spectacles at the final follow-up visit.

“In our study, the implantation of the Tecnis multifocal toric IOL in patients with cataract and corneal astigmatism provided efficacy and safety in restoring distance, intermediate and near vision, predictability of the refractive results and rotational stability,” the study authors said. – by Robert Linnehan
