Photographs of implanted PEG/PAA hydrogels taken prior to collection of tissue. (A,B) Rabbit 7 and 8 had implantations for 6 months, however rabbit 8 developed an inflammatory response likely due to infection at 3 months and had subsequent scarring and opacification of its cornea. (C) There was extrusion of the implant 4 months from rabbit 9, leaving a light haze afterwards. (D,E) Rabbits 10 and 11 had implantations for 9 months and 12 months respectively, and both demonstrated epithelial defects (yellow arrows). (F) Rabbit 12 had clear cornea even at 16 months, though histology revealed epithelial ingrowth over part of the implant.
