Methods: Forty cataract patients with high myopia combined with astigmatism were included from June 2022 to October 2023, and were divided into the experimental group and the control group according to the patients’ wishes, with 20 cases in each group. All patients underwent conventional cataract aspiration with ultrasonic emulsification, and the experimental group was implanted with astigmatism-corrected multifocal IOLs, while the control group was implanted with astigmatism-corrected monofocal IOLs. The changes of naked eye distance visual acuity, naked eye near visual acuity, best-corrected distance visual acuity, astigmatism and patient satisfaction at 3 months after surgery were compared. Results: There was no significant difference observed between the two groups prior to the surgical procedure. However, at 3 months post-surgery, statistically significant disparities were found in uncorrected near visual acuity and uncorrected distance visual acuity between the two groups. Nevertheless, there was no statistically significant distinction in best corrected distance visual acuity. The disparity in residual corneal astigmatism between the two groups exhibited statistical significance. Furthermore, the experimental group demonstrated a significantly higher postoperative visual function score compared to that of the control group. Conclusion: The implantation of astigmatism-correcting multifocal IOLs in patients with high myopia complicated by cataract and astigmatism can achieve good distance and near visual acuity and improve the patients’ ability to visualize both distance and near, and the patients’ satisfaction is high.展开更多
