CLINICAL AND HISTOLOGICAL RESULTS OF EXPERIMENTAL USE OF IMPLANTS BASED ON CROSS-LINKED COLLAGEN AS DONOR CORNEA ANALOGUE

Odessa, Ukraine

Bioengineered substitute of the corneal stroma (BSCS) was synthesized by porcine type I collagen cross-linking with 1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide and N-hydroxysuccinimide. The obtained transparent implant had optical and mechanical properties similar to the human cornea. It showed satisfactory biocompatibility when was implanted into rabbit corneas (8 rabbits — 8 eyes): BSCS has preserved its clarity during 12 months of the follow-up. Fine opacities of the superficial corneal layers have been observed in 2/8 eyes during the 1st postoperative week. In 1 eye opacity resolved, in the 2nd eye tiny fine opacity was formed. Light microscopy confirmed good integrity of the implants and absence of inflammation in the corneal stroma. Our data suggest that BSCS synthesized by collagen cross-linking might be a potential material for keratoplasty.
