Abstract:
Objective To evaluate the effects on trabeculectomy combined with implantation of anterior lens capsule.Design Radomized,controlled experimental study.Participants 36 experimental albino rabbits.Methods 36 albino rabbits were divided into 3 groups randomly.The rabbit and human anterior lens capsules were implanted under the scleral flap in trabeculectomy in group A and group B respectively,while only trabeculectomy in control group.The average follow-up period was 12 months.Main Outcome Mea- sures Intraocular pressures(IOP),filtering bleb,complications.Results The postoperative IOP of the experimental groups decreased sig- nificantly as compared with preoperative IOP at 12 week postoperatively.Retention of reflective filtering bleb in experimental groups was longer than that in contral group(5.12?0.43week,5.05?0.59week,2.74?0.32week,P＜0.05).The passage of humor outflow kept open in ex- perimental groups and became closed in control group at 12 week postoperatively.Anterior lens capsule wasn't attacked by T or B lym- phocyte seen with electron microscope.Conclusions Implantation of anterior lens capsule may help to postpone filtering bleb scarring in the trabeculectomy.This study provides experimental basis for the clinical practice.
