Inert intraocular eyelash foreign body following phacoemulsification cataract surgery.

INTRODUCTION: We describe the first reported case of tolerated eyelash inoculation following phacoemulsification surgery, with 4 years follow-up, that did not result in endophthalmitis or low grade chronic uveitis. CASE REPORT: A 79-year-old man with bilateral cataracts underwent phacoemulsification and posterior chamber intraocular lens implantation in the right eye. Three months later, he was found to have an eyelash within the right anterior chamber. The patient opted to leave his asymptomatic right eye alone. Four years later, he was referred to our hospital for review of his intraocular foreign body. He had remained asymptomatic with bilateral 6/6 vision, and without pain, photophobia or monocular diplopia. He declined surgery to remove the foreign body and opted for annual review. DISCUSSION: Intraocular implantation of cilia is a rare surgical complication following cataract surgery. The reaction of the eye to cilia has been reported to be variable and unpredictable, varying from absolute lack of reaction to endophthalmitis. Careful preoperative preparation can prevent similar incidents with potential complications. The position of the cilium is an important consideration. In contrast to other organic materials, a cilium is relatively inert and is rarely associated with infection. Acute inflammation most commonly occurs within days or after a few months, although the eye can tolerate the cilium for many years. Some ophthalmologists prefer observation, particularly when there is no inflammation present. We believe that each patient should be considered on an individual basis. The decision to remove an intraocular eyelash remains controversial and should be considered at the onset of inflammatory or infective clinical signs.
