Abstract:AIM: By comparing the aspheric and multifocal Toric intraocular lens and the aspheric intraocular lens in cataract patients, to observe the patients' visual quality, to evaluate the patients' distance visual acuity, near visual acuity, Pseudo-accommodative power, residual astigmatism, the rotational stability of AcrySof IQ Toric Restor intraocular lens(IOLs), contrast the rate of off-distance glass, the rate of off-near glass and patient satisfaction after the implantation of AcrySof IQ Toric Restor IOL in the cataract patients with preexisting corneal astigmatism.
METHODS:Carried out in 46 patients(48 eyes)with age-rated cataract who receiving phacoemulsification and implantation of artificial lens in our department during February 2014 to June 2016. All the cases were randomly divided into 2 groups: experimental group: 23 cases(24 eyes), AcrySof IQ ReSTOR Toric IOL was implanted after phacoemulsification; control group: 23 cases(24 eyes), AcrySof IQ was implanted. Uncorrected distance visual acuity(UCDVA)and best corrected distance visual acuity(BCDVA), uncorrected near visual acuity(UCNVA)and best-corrected near visual acuity(BCNVA), Pseudo-accommodative power, residual astigmatism, preoperative and postoperative corneal astigmatism, the rate of off-distance glass, the rate of off-near glass and patient satisfaction were measured at 6mo postoperatively follow-up.
RESULTS: BCDVA and BCNVA were not statistically different between the two groups(P<0.05). At 1wk, 1, 3 and 6mo postoperatively of UCDVA the experimental group were statistically better than the control group(P<0.05). UCNVA were also statistically better than the control group(P<0.05). The mean residual astigmatisms 1wk, 1, 3 and 6mo postoperatively were statistically differences between the control group and experimental group(P<0.05). At 6mo postoperatively, patients satisfaction of experimental group were significantly better than control group(P<0.05). Spectacles independence for near vision achieved 83% and 17% in experimental group and control group, experimental group were statistically better than control group(P<0.05). Spectacles independence for distance vision achieved 92% and 67% in experimental group and control group, experimental group were statistically better than control group(P<0.05).
CONCLUSION:The results indicate that AcrySof IQ ReSTOR Toric IOLs may provide a better uncorrected distance visual acuity and uncorrected near visual acuity, which can significantly reduce preexisting corneal astigmatism in cataract surgery, improve spectacles independence for distance vision and spectacles independence for near vision, have a high patient satisfaction.
