A novel complication following cataract surgery was identified in 9.5% of patients. This involved inflammation and scleral excavation near the wound, potentially linked to suture material.

Area of Science:

  • Ophthalmology
  • Surgical Complications

Background:

  • Extracapsular cataract extraction (ECCE) with posterior chamber intraocular lens (PC IOL) implantation is a common surgical procedure.
  • Uncomplicated ECCE typically has a low complication rate.

Observation:

  • A cluster of symptoms including foreign body sensation, conjunctival injection, and scleral infiltrates were observed.
  • Scleral excavation beneath the nylon suture was noted in affected patients.
  • Symptoms presented 1-6 weeks post-surgery.

Findings:

  • The study identified a previously unreported complication in 9.5% of patients undergoing ECCE.
  • Inflammation localized to the conjunctiva and sclera adjacent to the cataract wound was the primary finding.
  • Microscopic analysis revealed eosinophils and polymorphonuclear leukocytes in some cases; cultures and toxicology were negative.

Implications:

  • This finding highlights a potential new complication associated with ECCE and PC IOL.
  • The exact etiology of this localized scleral inflammation remains undetermined.
  • Further research is needed to elucidate the cause and guide management of this postoperative complication.
