Comparator / control treatment
Nil comparator as this is a retrospective trial looking at the number of recurrences following Diamond Burr Superficial Keratectomy via chart reviews of patients that have undergone the procedure.

Outcomes
Primary outcome [1] 286637 0
Decrease in the incidence of corneal erosions.

Corneal erosions are extremely painful and the patients that have undergone treatment have had several episodes. Therefore patients will self-report re-occurence at either a follow up appointment or via a telephone interview. The telephone interview is required for patients that have not been seen 6 months post treatment. The primary outcome will be whether the corneal erosion returned or was successfully treated.
