Abstract:AIM: To investigate the clinical efficacy of Toric intraocular lens(IOL)implantation for cataract patients with corneal astigmatism.
METHODS: Thirty-eight patients(46 eyes)with corneal astigmatism undergone phacoemulsification and IOL implantation in our hospital from June 2013 to July 2014 were observed. Twenty cases(24 eyes)received Toric IOL, 18 cases(22 eyes)got Acrysof IQ IOL. The clinical efficacy of the two groups was analyzed.
RESULTS:The difference on visual acuity after surgery between the two groups was statistically significant(F=5.783, P<0.05). The uncorrected visual activity of the observed group after 1wk, 1 and 3mo was significantly higher than that before the operation, the difference was statistically significant(P<0.05); The uncorrected visual activity of the observed group was significantly higher than that in the control group, the difference was statistically significant(t=5.248, 2.573, 2.782; all P<0.05). The difference on the degree of astigmatism after surgery between the two groups was statistically significant(F=5.482, P<0.05). At 1wk, 1 and 3mo after the operation treatment, the degree of astigmatism in the observed group was lower than that before operation, the difference was statistically significant(P<0.05); The degree of astigmatism in the observed group was lower than that in the control group, the difference was statistically significant(t=6.591, 3.287, 2.167; all P<0.05). The results of distance vision study suggested that 75% patients with IOL implantation do not need to wear spectacles.
CONCLUSION: Phacoemulsification associated with Toric IOL implantation has good correction effect and prediction for cataract and corneal astigmatism patients, and can improve the visual activity significantly, so it is worthy of clinical application.
