Presoaked collagen corneal shields are used as a means for the delivery of antibiotics to the corneal epithelium and stroma and the anterior chamber. We report a case of macular infarction that occurred in a patient after the placement of a gentamicin sulfate-impregnated collagen corneal shield following cataract surgery.

Report of a Case.  An 80-year-old man underwent extracapsular cataract extraction with phacoemulsification of the lens nucleus and implantation of a posterior chamber intraocular lens in the left eye. Preoperative visual acuity was 6/120 OS. Clinical evaluation demonstrated a visually significant cataract and mild atrophic retinal pigment epithelial changes. Visual acuity in the fellow eye was 6/12 with similar retinal pigment epithelial changes noted. A 5-mL peribulbar injection was performed with a 1.6-cm 27-gauge needle using equal amounts of 1% lidocaine hydrochloride (without epinephrine) and 0.5% bupivacaine hydrochloride and 0.5 mL (75 U) of hyaluronidase.
