- Fluorescein Staining [0 day preoperatively]
The corneal surface was divided into four regions, and each region was scored as follows: 0, no staining; 1, between one and three dots; 2, less than five dots; and 3, bulk or strip staining. The four regions scores were then added to obtain a final score for the eye
