Clinic application of rebuilding the capsule bag in secondary intraocular lens implantation in children with aphakia eye

Abstract

Objective To discuss the necessity and possibility of rebuilding the capsule bag in children with aphakia eye who need secondary intraocular lens (IOL) implantation.Methods Retrospective analyzed 196 aphakic eyes of 110 children who experienced secondary IOL implantation.All the patients implanted the IOL under general anesthesia,groupA was 108 eyes of 60 patients,the technical of rebuilding the capsule bag was used and the IOL was implanted in the capsule bag,group B were 88 eyes of 50 patients,the IOL implanted in the ciliary groove.All the patients were implanted acrylic three-piece IOL (SensarAR40e:America AMO).The visual outcome and complication in early (1 day to 1 month post-operation),middle (1 month to 3 months post-operation) and later (3 to 12 months) stage of post-operation were observed.Results The visual outcome:all the patients had increased the vision after lyear post-operation.Group A,all the eyes had increased the vision to equal or more than 3 Snellen lines.Group B 70％ of patients had increased the vision to equal or more than 3 snellen lines.There was significant changes between the two group (u=6.158,P ＜0.05).The complication in early stage post-operation:formation of exudation lemma in the anterior chamber 2 eyes in the group A,and 12 eyes in the group B.The difference was statistically significant (x2=8.453,P ＜0.005).Pupil retardancy glaucoma had not happened in the group A but happened 2 eyes in the group B.The difference was statistically significant.The complication in middle stage post-operation:exudation membrane in the anterior chamber observed 1 eye in the group A and 10 eyes in the group B,The difference was statistically significant (x2=8.099,P ＜0.005).Pupil retardancy glaucoma was happened no eye in the group A but happened 2 eyes in the group B.The difference was statistically significant.The complication in later stage post-operation:formation of exudation membrane in the anterior chamber 1 eye in the group A and 8 eyes in the group B.The difference was statistically significant (x2=5.633,P ＜0.025).The IOL transposition occurred 0 eye in the group A and 6 eyes in the group B.The difference was statistically significant.Conclusions The application of rebuilding the capsule bag in children with aphakic eye can not only make the IOL implanted in the capsule bag,but also can decrease the complication of post-operation Key words: Rebuilding the capsule bag; Child; Aphakic eyes; Intraocular lens; Implanted in the bag
