To evaluate and compare the functional and cosmetic results of eyes submitted to two types of keratoplasty in dogs with deep or perforating corneal lesions, the medical records of three surgeons were reviewed. Seventy-five eyes were included, treated with corneoconjunctival transposition (CCT) or porcine intestinal submucosal membrane graft (MSIS). Data such as gender, age, breed, affected eye, healing time, complications, vision and corneal transparency were reviewed. Eighty-five percent of eyes remained visual; being 23/25 (92%) with CCT, and 9/50 (82%) with MSIS. The two techniques proved to be efficient, and CCT had a shorter healing time and a lower rate of complications when compared to MSIS. The chance of graft dehiscence was 6 times greater when using the membrane (OR = 18.36 with 95% Confidence Interval CI: 1.043 – 323.1); and postoperative granulation was 18 times greater on the membrane (p = 0.003). The TCC group had a greater number of eyes with grade 1 opacity after 60 days (44%), and 80% of the eyes obtained grades 1 and 2, giving greater final transparency compared to those operated on with membrane.
