Abstract

Objective: To compare visual quality and satisfaction after multifocal toric intraocular lens (Acrysof IQ Restor toric, ART) and monofocal toric intraocular lens implantation in patients. Methods: It was a prospective nonrandomized Phase Ⅲ clinical trial. Patients with age-related cataract and corneal astigmatism were enrolled and accepted phacoemulsification combined with implantation of intraocular lens (IOL) in Henan Provincial Eye Hospital during March 2013 to December 2014. Fifty-six cases were divided into two groups according to which IOL they chose. ART group included 28 cases (3l eyes) aged from 41.0 to 72.0 years, with an average age of 61.5 years; toric group included 28 cases (33 eyes) aged from 42.0 to 75.0 years, with an average age of 63.5 years. Three months postoperatively, uncorrected distance visual acuity (UDVA) at 5, 70, 40 cm, corrected distance, intermediate, and near visual acuities, defocus curve, residual refractive astigmatism, rotational stability of the IOL, contrast sensitivity and patientsatisfaction were evaluated. All data were processed by statistic package deal SPSS 16.0. Postoperative visual acuity, residual astigmatism, IOL axial rotation and contrast sensitivity were compared by independent samples t test; preoperative and postoperative corneal astigmatism were compared by paired t-test; spectacle independency and halo incidence were processed by χ(2) test; visual satisfaction score was analyzed by Mann-Whitney test. Results: At 3 months postoperatively, in ART group, UDVA was (0.04±0.05), UIVA was (0.24±0.15), UNVA was (0.20±0.24). While in Toric group, UDVA was (0.06±0.04), UIVA was (0.30±0.13), UNVA was (0.47±0.21). There was no significant difference in UDVA between two groups(t=0.79, P=0.433). But in ART group, UIVA and UNVA were markedly better than those in Toric group(t=2.74, P=0.008; t=3.45, P0.05), while the intermediate and near visual satisfaction scores were significantly different(Z=2.27, P<0.05; Z=2.60, P<0.05) Conclusions: Both of the ART IOL and toric IOL can correct patients astigmatism. Implantation of ART IOL in patients with cataract and corneal astigmatism provided excellent distance, intermediate, and near visual outcomes. It provided better predictability of the refractive results, nice rotational stability, and good optical performance. At the same time, it improved the spectacle independency of cataract patients with astigmatism. (Chin J Ophthalmol, 2017, 53: 274-280).
