Scoring system for graft status
| Neovascularisation (most advanced head) | |
|---|---|
| 0, none | |
| 1, within peripheral half of recipient cornea | |
| 2, within central half of recipient cornea | |
| 3, at interlamellar pocket but not reaching graft | |
| 4, within peripheral half of graft | |
| 5, within central half of graft | |
| Opacity | |
| 0, clear | |
| 1, iris vessels and/or pupil partly obscured | |
| 2, whole pupil obscured | |
| 3, anterior chamber not visible | |
| Oedema (slit beam oblique illumination, maximal thickness) | |
| 0, no change | |
| 1, increased thickness, but less than twice normal thickness | |
| 2, equal or greater than twice but less than three times normal thickness | |
| 3, equal or more than three times normal thickness | |
| Granularity (slit beam oblique illumination) | |
| 0, none | |
| 1, mild, “granules” occupying less than half of corneal cross section | |
| 2, moderate, “granules” occupying about half of corneal cross section | |
| 3, dense, “granules” occupying more than half of corneal cross section |
