ABSTRACT

@#AIM:To analyze the effect of phacoemulsification and astigmatism corrected multifocal intraocular lens(IOL)implantation on corneal astigmatism and visual quality in cataract patients. <p>METHODS:Ninety-five patients who underwent ophthalmic surgery in our hospital for cataract disease between December 2016 and February 2018 were studied. All subjects were randomized and compared. Both groups were treated with phacoemulsification. The control group was treated with astigmatism-corrected monofocal intraocular lens implantation. The observation group was combined with astigmatism-corrected multifocal intraocular lens implantation. The differences in corneal astigmatism, visual quality, and vision improvement were compared between the two groups.<p>RESULTS: Uncorrected distance vision, best corrected distance vision, uncorrected near vision and best corrected near vision were significantly improved in the two groups after treatment at 3mo after operation. The degree of improvement in the observation group was significantly higher than that in the control group(<i>P</i><0.05). The corneal astigmatism of the two groups was significantly improved after treatment(<i>P</i><0.05). There was no significant difference between the two groups(<i>P</i>>0.05). After the treatment,the visual contrast sensitivity was significantly increased(<i>P</i><0.05). The visual contrast at the 18 cpd spatial frequency in the observation group was significantly lower than that in the control group(<i>P</i><0.01).One day after surgery, only two eyes in the observation group showed corneal endothelial edema, and only one eye in the control group showed corneal endothelial edema. There was no significant difference in the incidence of complications between the observation group and the control group(<i>P</i>>0.05).<p>CONCLUSION: The treatment of cataract patients with phacoemulsification and astigmatism-corrected multifocal IOL implantation can effectively correct vision, reduce corneal astigmatism, and improve visual contrast. The entire surgical procedure is safe and has fewer postoperative complications.
