Abstract

Objective

This study aimed to evaluate the visual performance and rotational stability of the multifocal toric intraocular lens in myopes.

Methods

This prospective, observational study included patients with an axial length of ≥24.5 mm and regular corneal astigmatism of >1 diopter who underwent phacoemulsification cataract surgery and implantation of a multifocal toric intraocular lens (AT LISA toric 909M). The visual acuity, defocus curves, residual astigmatism, rotational stability, higher-order aberrations (HOAs), modulation transfer function (MTF), spectacle dependence and patient satisfaction were evaluated 3 months after surgery.

Results

Forty-three eyes from 30 patients were enrolled in this study. Postoperatively, uncorrected distance and near visual acuities (logMAR) were 0.09 ± 0.08 (standard deviation, SD) and 0.14 ± 0.08, respectively. The defocus curve analysis provided a bimodal curve showing two peaks of maximum vision at 0.0 D and at −3.0 D defocus level. The multifocal toric intraocular lens showed excellent rotational stability; the mean rotation was 4.02 ± 2.49 (SD) degrees at 3 months postoperatively. Refractive predictability was excellent with a mean spherical equivalent of 0.19 ± 0.37 (SD) diopters (D) and a mean refractive cylinder of -0.34 ± 0.39 (SD) D.

Conclusions

The diffractive multifocal toric intraocular lens, AT LISA toric 909M, provided effective distance and near visual acuities in myopic eyes. It was a predictable and effective device with good rotational stability for the correction of preexisting astigmatism during cataract surgery. In this study, more than 80% of patients achieved spectacle independence.
