๐ What is CCC in Cataract Surgery?
Modern cataract surgery primarily involves
phacoemulsification followed by posterior chamber intraocular lens (IOL) implantation.
A critical step in this process is
CCC (Continuous Curvilinear Capsulorrhexis).
๐งฌ What is CCC?
- A smooth, round opening (~5–5.5 mm) is created in the anterior lens capsule
- Allows safe access for phacoemulsification and IOL insertion
- Essential for capsular bag integrity and surgical safety
๐ Techniques
- Manual: Using cystotome or CCC forceps
- Enhanced visualization:
- Retroillumination
- Capsule staining dyes (Trypan Blue, ICG)
- Laser-assisted CCC:
- Performed with femtosecond laser
- Provides precision and symmetry
๐งช Capsule Staining Dyes
DyeNotes
| Trypan Blue | Most widely used, safe |
| Indocyanine Green | Good visualization |
| Gentian Violet | Limited use |
| Fluorescein | Rare, for fluorescence |
โ Summary
- CCC is one of the most important steps in cataract surgery
- Enables safe lens removal and IOL placement
- Smooth, circular tears = better visual outcome
- Modern lasers can automate this process for precision
