AIM： To evaluate the refractive outcome of Toric Lentis Mplus intraocular lens（IOL） implant.· METHODS： This is a retrospective case series.Consecutive patients with corneal astigmatism of at least1.5 D had Toric Lentis Mplus IOL implant during cataract surgery. The exclusion criteria included irregular astigmatism on corneal topography, large scotopic pupil diameter（〉6 mm）, poor visual potential and significant ocular comorbidity. Postoperative manifest refraction,uncorrected distance visual acuity（UDVA）, best-corrected distance visual acuity（BCVA）, uncorrected intermediate visual acuity at（UIVA） 3/4 m and uncorrected near visual acuity（UNVA） were obtained.·RESULTS： There were 70 eyes from 49 patients in this study. Patients were refracted at a median of 8.9wk（range 4.0 to 15.5） from the operation date. Sixty-five percent of eyes had 6/7.5（0.10 log MAR） or better, and99% 6/12（0.30 log MAR） or better postoperative UDVA.Eighty-nine percent could read Jaeger（J） 3（0.28 log MAR）and 95% J5（0.37 log MAR） at 40 cm. The median magnitude of astigmatism decreased from 1.91 D to 0.49 D（Wilcoxon, P〈0.001） after the operation. The range of the cylindrical error was reduced from 1.5-3.95 D（keratometric） preoperatively to 0.00-1.46 D（subjective refraction transposed to corneal plane） postoperatively.· CONCLUSION： Toric Lentis Mplus IOL has good predictability in reducing preexisting corneal astigmatism.
