Effect of bandage contact lens wear and postoperative medical therapies on corneal healing rate after diamond burr debridement in dogs.

Austin – mechentel news – To determine the effect of bandage contact lens wear and type of post-operative medical treatment on corneal healing rates in 237 client-owned dogs after diamond burr debridement., canine patients having undergone diamond burr debridement (DBD) for treatment of spontaneous chronic corneal epithelial defects (SCCEDs) were included in this study and were put into 1 of 12 different groups based on type of postoperative medical regimen and whether a bandage contact lens (BCL) was utilized. Each dog was examined on a routine basis until the cornea was fluorescein negative. Data points collected included age, sex, breed, diabetic status, eye affected, Schirmer tear test 1, rebound tonometry, type and frequency of topical antibiotic, use of topical sodium chloride, use and retention of BCL, and days until healed. A total of 237 dogs, each contributing one eye to the study, underwent DBD for SCCEDs. All eyes treated had estimated median ± standard error (SE) days to heal of 9.37 ± 0.42 days. When sodium chloride and BCL were utilized, ofloxacin had a significantly shorter median healing time when compared to oxytetracycline (adjusted P = 0.0158) and tobramycin (adjusted P = 0.0261). BCL use significantly improved healing times (P = 0.0002). Overall BCL retention rate was 62.02% (80 of 129). PureVision lenses were retained more often compared to Acrivet lenses (P < 0.0001). Overall, BCL retention significantly improved healing rates (P = <0.0001). The autors concluded: Postdebridement antibiotic type or use of sodium chloride ointment had minor effects on healing rates. Bandage contact lens use and retention significantly improves healing times. (pubmed, mm)
