To report a case of subconjunctival foreign body migration in both eyes after collagen-containing filler injection.

A 51-year-old female, who had been treated with collagen-containing filler in her eyelid, nose, and forehead for cosmetic complaints four months earlier, presented to our clinic with decreased visual acuity and foreign body sensation in both eyes. Slit lamp examination revealed moderate nucleosclerosis and subcapsular opacity in her crystalline lens, in addition to scattered subconjunctival foreign body infiltration in both eyes. Cataract extraction with posterior chamber lens implantation was performed, and the subconjunctival foreign body was also partially removed. Biopsy of the remaining foreign body was performed, and examination revealed foreign material and multivacuolated cells in the conjunctiva.

Clinicians and patients should be aware of the risk of migration of collagen-containing filler inject at or near the eyelid, to the eyeball, including the conjunctiva.
