๐ Modern Cataract Surgery: Phacoemulsification & IOL Insertion
The current standard method for cataract surgery is
phacoemulsification followed by posterior chamber intraocular lens (IOL) implantation.
Though femtosecond laser is occasionally used, ultrasound remains central to cataract removal.
๐งฌ Key Surgical Steps (Simplified)
- Corneal Incision
- Creates an entry point for surgical tools
- CCC (Continuous Curvilinear Capsulorrhexis)
- A 5.0–5.5 mm circular opening is made in the lens capsule
- Phacoemulsification
- The cloudy lens is fragmented and removed via ultrasound energy
- Posterior Chamber IOL Insertion
- An intraocular lens (IOL) is inserted into the posterior capsule
- Mimics the natural lens location
๐ง Basic Eye Space Terms
TermDefinition
| Anterior Segment | Front of the eye (cornea to lens) |
| Anterior Chamber | Space in front of iris |
| Posterior Chamber | Behind iris; where lens resides |
| Posterior Segment | Retina, vitreous, optic nerve |
โ Summary
- Cataract surgery has evolved to focus on precision and safety
- Phacoemulsification uses ultrasound to remove the lens
- IOL is placed where the original lens was, ensuring best alignment
- CCC is essential for safe access and support for the IOL
