The Effects of the Cyanoacrylate Tissue Adhesive Mono-therapy for Corneal Perforation

PURPOSE: To report cases of corneal perforation among corneas treated with cyanoacrylate tissue adhesive. METHODS: We performed cyanoacrylate tissue adhesive application on 1 case of corneal perforation due to fungal keratitis, one case of corneal perforation due to neurotrophic keratitis, one case of corneal fistula due to foreign body and one case of corneal perforation due to corneal stromal dystrophy. After cyanoacrylate tissue adhesive removal, amniotic membrane transplantation was conducted in two cases, and keratoplaty was performed in another two cases. RESULTS: Postoperative follow-up period was 12 months on average. In all four cases, ocular integrity was successfully restored. There was no sign of recurrence, infection or inflammation. CONCLUSIONS: Cyanoacrylate tissue adhesive monotherpy can restore ocular integrity successfully in various type of corneal perforation and After cyanoacrylate tissue adhesive removal, amniotic membrane transplantation and keratoplaty can be performed additionally.

Results of Penetrating Keratoplasty with Scleral-Fixated Posterior Chamber Lens for Aphakic Bullous Keratopathy

Penetrating keratoplasty with or without intraocular lens implantation is necessary to restore a vision of an eye with aphakic bullous keratopathy. We analyzed surgical outcomes in eleven aphakic bullous keratopathy patients(11, eyes) who received penetrat-ing keratoplasty with scleral-fixated posterior chamber lens(PCL)at Kangnam St.Mary's hospital from January, 1989 to December 1991 and followed up more than 1 year Eight of eleven eyes showed the postoperative corrected VlSlOn of 0.3 to 0.8 at postoperative one year. The cuases of poor vision below 0.3 were age-related macular degeneration(1 eye), graft failure(I eye) and diabetic retinopathy(1 eye). At one year after surgery, mean spherical equivalent was-1.12, mean astigmatism was 4.21D and percent loss of corneal endothelium was 35.5%. Graft rejection(3 eyes) and secondary glaucoma(1 eye) were occured during the postoplasty with scleral-fixated PCL can be an excellent surgical technique to get visual rehabilitaion of patients with an aphakic bullous keratopathy.
