Study on visual quality and patient satisfaction after astigmatic multifocal intraocular lens implantation

AIM: To observe the postoperative visual quality and patient satisfaction of AT LISA Toric 909MP(909M)astigmatic corrected multifocal IOL and AT TORBI 709M(709M)astigmatic corrected single-focus IOL after phacoemulsification.METHODS: Patients with age-related cataract and corneal astigmatism(>1.0D)were enrolled and accepted phacoemulsification combined with implantation of intraocular lens(IOL)in our hospital during December 2017 and December 2018. Forty cases(56 eyes)were divided into two groups according to which IOL they chose, multiple focal astigmatism(909M)group included 23 cases(35 eyes), single focal astigmatism(709M)group included 17 cases(21 eyes). Three months postoperatively, the visual acuity, defocus curve, residual astigmatism degree, rotational stability of the IOL, postoperative visual quality analysis and patient satisfaction were evaluated.RESULTS: At 3mo postoperatively, uncorrected distance visual acuity(UDVA)and corrected distance acuity in the two groups were significantly improved(PCONCLUSION: Both of the 909M and 709M had good correction effect for cataract combined with astigmatism. It provided better rotational stability. In addition, 909M provided excellent distance, near visual outcomes, and acceptable intermediate vision. At the same time, it improved the spectacle independency and satisfaction of cataract patients combined with astigmatism.
