Toxic anterior segment syndrome following implantable contact lens surgery

An Implantable Collamer Lens was implanted in a 24-year-old man with a refractive error of − 5.5 − 0.5 × 25 in the right eye. On postoperative day 1, the acuity was hand motions. There was limbus-to-limbus stromal edema with Descemet folds, the anterior chamber was deep, and the pupil was dilated. There was thin fibrin on the collagen copolymer intraocular lens. Vault could not be assessed. The patient was treated with topical steroids, systemic steroids, and topical antiglaucoma medications. At 3 months, the uncorrected distance visual acuity was 20/20 partial (missing letters). The eye was quiet, and the vault was good. The pupil was 4.0 mm and asymmetrical.There was diffuse iris atrophy and minute anterior subcapsular opacities. Based on the presentation and response to treatment, I believe this was a case of toxic anterior segment syndrome.
