Plain-English summary
A 5-year-old Beagle was brought in for a corneal ulcer known as a superficial chronic corneal epithelial defect (SCCED), which can cause eye problems and discomfort. The veterinarian treated the dog using either a diamond burr debridement (DBD) or a grid keratotomy (GK), both of which are surgical options to help the eye heal. The results showed that both treatments worked well, with no significant difference in healing time between the two methods. The dog recovered without major complications, although the study noted that the diamond burr tips used in the procedure can accumulate contaminants over time.

Abstract
OBJECTIVES: (i) Compare the outcome of canine SCCED treated with grid keratotomy (GK) or diamond burr debridement (DBD); (ii) Serially evaluate morphologic and elemental composition changes to diamond burr tips. ANIMALS STUDIED: A total of 91 eyes of 88 canine SCCED patients treated at the University of Missouri (2005-2015); 75 fresh cadaver porcine globes. PROCEDURES: (i) Medical records were reviewed retrospectively. Data were analyzed for age, sex, breed, procedure performed, eye(s) on which the procedure was performed, time to healing after a single surgical procedure, performance of a second surgical procedure, contact lens placement, and postprocedural complications. (ii) Three naïve 3.5-mm medium grit burr tips were analyzed using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). DBD was performed for 120 s on 8-mm porcine corneal stroma using the Algerbrush. Manufacturer-recommended cleaning protocols were followed. SEM and EDS analyses were performed in triplicate after 10, 25, and 50 DBD, cleaning, and sterilization cycles. RESULTS: There was no statistically significant difference in healing between DBD and GK groups (P = 0.50). No diamond particle damage after 10, 25, or 50 DBDs was detected. SEM secondary electron imaging and backscatter electron imaging after repeated uses demonstrated a build-up of contamination composed of carbon, sulfur, and calcium on burr tips. CONCLUSIONS: Both DBD and GK are effective treatment options for canine SCCED. Although complications are rare after DBD, build-up of contaminants may be a contributing factor. Additional cleaning and sterilization protocols are being investigated.
