摘要

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.
