π What is a Radial Tear During Cataract Surgery?
A radial tear is a complication in which the anterior capsule tears outward in a radial pattern
during CCC (Continuous Curvilinear Capsulorrhexis) in cataract surgery.
π Normal Cataract Surgery Steps
- Corneal Incision
- CCC – Circular tear in the anterior capsule
- Phacoemulsification – Lens emulsification & removal
- IOL Implantation – Lens placed in intact posterior capsule
β
Posterior capsule must remain intact
β If the radial tear extends posteriorly → poor outcome
β Risks of Radial Tear
- May propagate to the lens equator or posterior capsule
- Can progress into bilateral radial tears
→ known as the Argentina Flag Sign
π Marques Study (2006):
- <1% incidence
- Among those:
- 48% extended to posterior capsule
- 19% required anterior vitrectomy
π Management Strategy
SituationResponse
Tear detected early | Stop CCC → Fill with cohesive OVD |
New CCC | Start in opposite direction (clockwise), outside-in |
If unsuccessful | Use can-opener capsulotomy technique |
If stabilized | Proceed with IOL implantation |
β Summary
- CCC integrity is key to surgical success
- Radial tears must be quickly recognized and managed
- Prevention through technique & awareness is most effective
