To evaluate the long-term clinical effect of cataract phacoemulsification combined with astigmatism in patients implanted with AcrySof IQ ReSTOR Toric MIOLs. Methods: This was a prospective analysis. Fifty patients (82 eyes) underwent cataract phacoemulsification combined with astigmatism correction with IOL implants in Oilfield General Hospital of Daqing. The patients were followed up for 1 year to assess uncorrected distance visual acuity (UDVA, LogMAR), uncorrected intermediate visual acuity (UCIVA, LogMAR), uncorrected near visual acuity (UNVA, LogMAR), best corrected distance visual acuity (BCDVA, LogMAR), best corrected intermediate visual acuity (BCIVA,LogMAR), best corrected near visual acuity (BCNVA, LogMAR), defocus curve, contrast sensitivity (CS), total eye aberrations, estimated residual astigmatism and analysis of axis deviation of the artificial IOL, and spectacle independence preoperatively and 3 months, 6 months, and 1 year postoperatively. Data were analyzed by repeated measured analysis of variance. Results: Postoperative vision was better than preoperative vision and the difference was statistically significant (F=26.39, P<0.001; F=13.68, P<0.001; F=12.90, P<0.001). At 6 months after the operation, the uncorrected distance visual acuity was close to 0, and visual acuity with +1.2 - -4.0 D defocus could reach more than 0.3. Under glare conditions, contrast sensitivity was best during the day and was worst at night 1 year after the operation and the difference was statistically significant. Residual astigmatism at 1 year was significantly reduced compared to baseline (0.24±0.15 D vs 1.56±0.38 D, t=3.31, P=0.023), and was not a statistically significant difference from the preoperative anticipated residual astigmatism (t=2.31, P=0.102). At 1 year, the mean IOL axis rotation was 3.12°±1.51°. All the patients independent of spectacle. Conclusions: The AcrySof IQ ReSTOR Toric astigmatic MIOL provides satisfactory full vision, visual quality, predictability, and good rotational stability for cataract patients.
