Abstract Purpose:To evaluate the efficacy and safety of monofocal toric intraocular lens(IOL)(VivinexTM Toric, XY1AT3-7:HOYA)which has the same material as monofocal IOL(XY1:HOYA).

Methods:This clinical trial was made on 20 eyes of 15 cataract patients with corneal astigmatisms. The age averaged 73.7 years. The corneal astigmatism averaged 1.74D. XY1AT was implanted with the target refraction of emmetropia and the model was selected using HOYA toric calculator. Uncorrected and corrected distance visual acuity(UCDVA/CDVA), residual astigmatisms, axis rotation, patient satisfaction, and the rates of spectacle usage were evaluated for 3 months postoperatively.

Results:The mean logMAR UCDVA and CDVA were −0.02±0.08 and −0.13±0.06, All the eyes achieved decimal VA of 0.8 or better. The mean residual astigmatism was 0.53±0.35D and the mean axis rotation was 4.9±3.1 degrees 3 months postoperatively. From the questionnaire, 60% of the patients answered very satisfied and 40% answered satisfied. The use of eyeglasses for distance decreased from preoperative 70% to 5%.

Conclusion:XY1AT3-7 was effective and safe for cataract eyes with corneal astigmatisms.
