Rotationally Asymmetric Multifocal IOL Implantation With and Without Capsular Tension Ring: Refractive and Visual Outcomes and Intraocular Optical Performance

Abstract

PURPOSE: To ascertain whether the refractive, visual, and intraocular optical quality outcomes of a rotationally asymmetric multifocal intraocular lens (IOL) are enhanced by the use of a capsular tension ring. METHODS: Ninety consecutive eyes from 53 patients (age range: 36 to 82 years) were divided into two groups: the no ring group comprised 43 eyes implanted with the multifocal rotationally asymmetric Lentis Mplus LS-312 (Oculentis GmbH) without a capsular tension ring; and the ring group comprised 47 eyes with the same IOL with a capsular tension ring. Distance and near visual acuity and refractive outcomes were evaluated pre- and postoperatively. Contrast sensitivity, intraocular aberrations, and defocus curve were evaluated postoperatively. RESULTS: Significant postoperative differences between groups were found in sphere, spherical equivalent refraction, and near addition ( P ⩽.02). Regarding defocus curve, significantly better visual acuity was present in eyes with the capsular tension ring for intermediate vision conditions ( P ⩽.05). Intraocular aberrometry did not differ significantly between groups ( P ⩾.09). CONCLUSIONS: Refractive predictability and intermediate visual outcomes with the Lentis Mplus LS-312 IOL improved significantly when implanted in combination with a capsular tension ring.
