Successful Treatment with Combined PTK/PRK Guided by Intraoperative Skiascopy of Patients with Corneal Haze after Surface Ablation

used as a substitute not only for epithelial cell proliferation, but also as a substrate for epithelial cells to attach to, and was transplanted permanently to repair a large intraoperative conjunctival defect and to form a filtering bleb. Meanwhile, an additional temporary AM transplantation was used to protect the primary AM transplantation until epithelialization was complete. Although repair of conjunctival buttonholes with AM during trabeculectomy has previously been reported [1], the conjunctival area permanently replaced in this case was of exceptional size. In conclusion, permanent AM transplantation accompanied by simultaneous temporary AM transplantation can form an AM bleb. Permanent AM transplantation may be an appropriate alternative treatment option for large conjunctival defects that occur during trabeculectomy.
