The double-layer sign of the anterior lens capsule during continuous curvilinear capsulorrhexis (CCC) in cataract surgery is a rare phenomenon. This case report highlights the occurrence of this sign and provides a practical technique for managing it.
A 55-year-old Chinese woman presented with blurred vision in her left eye. She had a history of nuclear sclerotic cataracts, but no abnormalities of the anterior capsule were noted in her preoperative evaluation.
Nuclear sclerotic cataract in the left eye with no preoperative abnormalities of the anterior lens capsule.
During CCC, a double-layer sign of the anterior lens capsule was identified. The surgeon successfully managed the double-layer sign by simultaneously grasping both layers with capsulorhexis forceps to complete CCC without complications.
Postoperatively, the patient achieved 20/20 vision in the treated eye, and no complications were observed.
The double-layer sign of the anterior lens capsule is a rare finding during cataract surgery. Although its exact cause remains unclear, the technique described offers a practical approach to manage this intraoperative challenge effectively.
