EFRON GRADING SCALE:
The Efron Grading Scales provide a standard clinical reference for describing the severity of contact lens complications.
The 16 sets of grading images cover the key anterior ocular complications of contact lens wear. The conditions are illustrated in five stages of increasing severity from 0 to 4, with 'traffic light' colour banding from green (normal) to red (severe) - providing a simple and convenient aid for the optical professional
Cornea and Contact Lens Research Unit Grading scale.
Provides photographic grades of bulbar hyperaemia, palpebral hyperaemia roughness, and corneal staining, from 0 to 4.
Both are simple methods of ocular condition grading, against which any future tissue change may be assessed and therefore enabling choices as to the best course of action.
Additionally, you can take a picture of your patient with the smartphone camera to compare it with the images of the scales. You can also check a previously taken image, from the photo gallery of your device.
