Table 2. Lens opacities classification system defines the extent of opacification of lens cortex opacification and posterior subcapsule of lens.
| Cortical standard | Description |
|---|---|
| C0 | Clear lens devoid of aggregated dots, flecks, |
| Ctr | Minimal degree of cortical opacification and/or |
| CI | More extensive opacification with small |
| CII | Cortical spoking that obscures more than 2 full |
| CIII | Opacification that obscures about 50% of the |
| CIV | Advanced opacification filling about 90% of the |
| Posterior subcapsule standard | Description |
| P0 | Clear posterior capsule |
| PI | Cataract filling about 3% of the area of the posterior capsule |
| PII | About 30% opacification of the area of the posterior capsule |
| PIII | About 50% opacification of the area of the posterior capsule |
