Indications for surgical management of retained lens fragments.

ABSTRACT

PURPOSE OF REVIEW Retained lens fragments are a relatively rare occurrence after cataract surgery. While no definite guidelines for the surgical management or timing of surgery of this complication exist, surgery is indicated for patients with large lens fragments, persistent inflammation, secondary glaucoma, corneal edema, retinal tears or detachments, and associated endophthalmitis. The aim of this review is to summarize the current surgical management of retained lens material. RECENT FINDINGS: The Intelligent Research in Sight registry database of 2.26 million patients who underwent cataract surgery in the US indicated that 0.18% (1 in 563) had secondary removal of retained lens fragments in the anterior chamber in the operating room within 1 year of the original cataract surgery. The risk of returning to the operating room for retained lens material removal was greater among men, smokers, patients with Medicaid or military insurance, and those who had complex cataract surgery. Medical management with topical corticosteroids or observation may be considered for small lens fragments, but surgical removal remains the mainstay of the treatment for large lens fragments. SUMMARY: Retained lens fragments following cataract surgery may result in various vision-threatening complications. Understanding the risk factors, diagnosis, and surgical management of retained lens fragments are critical to preserving good visual outcomes. Vitrectomy is effective in patients with posterior nuclear fragments, retinal detachment, endophthalmitis, or uncontrolled glaucoma not responding to medical management. The best timing for surgery for retained lens fragments should be further investigated in a prospective study.
