Objective: To explore the vision correction effect of phacoemulsification cataract extraction (Phaco) combined with bifocal Toric intraocular lens (IOL) implantation in cataract patients with preoperative corneal astigmatism.Methods: 92 cases (122 eyes) of cataract patients with corneal astigmatism treated in our hospital from January 2021 to May 2023 were selected and divided into the observation group (46 cases, 60 eyes) and the control group (46 cases, 62 eyes) using the envelope method. The observation group received Phaco combined with bifocal Toric IOL implantation, while the control group received Phaco combined with single focal Toric IOL implantation. The best corrected visual acuity (BCVA), astigmatism degree, corneal thickness, corneal surface curvature, and postoperative adverse reactions of the two groups of patients were observed and compared before and after the treatment.Results: Three months after the treatment, the BCVA of near vision and uncorrected near visual acuity of patients in the observation group were (0.07±0.01) LogMAR and (0.14±0.04) LogMAR, which were better than those in the control group (P<0.05). There was no statistically significant difference between and within the observation group and the control group in terms of corneal thickness, the minimum refractive power (FK1) in the radial direction of the flat anterior surface of the cornea, the maximum refractive power (FK2) in the radial direction of the steep anterior surface of the cornea at 3 months after treatment (P>0.05). There was no statistically significant difference in the total incidence of postoperative adverse reactions between the observation group and the control group (P>0.05).Conclusion: Phaco combined with bifocal Toric IOL implantation has shown good effect in correcting astigmatism and improving vision in cataract patients with preoperative corneal astigmatism.
