Comparison of clinical efficacy between I phase and II phase intraocular lens implantation for the treatment of traumatic cataract

Abstract

Objective To compare the clinical efficacy between Ⅰ and Ⅱ phase IOL implantation for the treatment of traumatic cataract. Methods Fifty patients of monocular traumatic cataract from Jan. 2016 to Jan. 2018 in Zhejiang Armed Police Corps Hospital were selected.All cases were randomly divided into two groups.There were Ⅰ phase IOL implantation group of 28 cases and Ⅱ phase IOL implantation group of 22 cases.The efficacy of the two groups was compared. Results One month after operation, the visual acuity of the two groups were significantly better than that before operation (P 0.05). One month after operation, the incidence of corneal edema, uveitis, posterior synechia and secondary glaucoma in II stage group were lower than that in I stage group (P<0.05). One year after operation, the anterior chamber depth and scores of tear film rupture time in Ⅱ phase group were higher than those in Ⅰ phase group (P<0.05), and the intraocular pressure and scores of corneal fluorescence staining were lower than those in Ⅰ phase group (P<0.05). Conclusion IOL implantation, the complication rate of the Ⅱ phase of traumatic cataract for the treatment is lower and the long-term effect is better.
