Double-layer sign of the anterior lens capsule during cataract surgery: A case report.

RATIONALE: 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.

PATIENT CONCERNS: 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.

DIAGNOSES: Nuclear sclerotic cataract in the left eye with no preoperative abnormalities of the anterior lens capsule.

INTERVENTIONS: 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.

OUTCOMES: Postoperatively, the patient achieved 20/20 vision in the treated eye, and no complications were observed.

LESSONS: 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.
