Abstract
Objective To assess and compare the outcomes of primary versus secondary intraocular lens (IOL) implantation for traumatic cataract in children.Methods 134 cases (134 eyes) of pediatric traumatic cataract in our hospital were randomly divided into two groups:group A (64 eyes,treated by primary IOL implantation) and group B (70 eyes,treated by secondary IOL implantation).Follow up was from 6 to 24 months.Results The recovery rate from blindness and disability were 90.6％ and 62.5％ in group A and 91.5％ and 80.0％ in group B at 6 months after surgery.There was no significant difference in recovery rate from blindness between two groups (x2 =0.026,P ＞ 0.5).The recovery rates from disability weresignificantly different between two groups (χ2 =5.03,P ＜ 0.05).The postoperative complications were severer in group A than group B in early and late stage.The incidences of pupil capture of IOL,posterior capsular opacity and secondary glaucoma were higher in group A than group B.The differences were statistically significant.Conclusion Traumatic cataract in children treated by secondary IOL implantation can have better visual outcomes and less surgical complications compared with primary IOL implantation.
