Iris implantation cyst is a secondary cyst formed as a result of invasion of conjunctival or corneal epithelial cells following surgery or penetrating wound.[1] In cases with no evidence of trauma, developmental anomaly with conjunctival tissue invasion into the iris stroma seems to be the underlying cause.[1]

A 24-year-old with a history of corneal perforation repair, presented with blurring of vision in left eye. His best corrected visual acuity was 6/9 (Snellen) and intraocular pressure 18 mmHg. Examination revealed an inferior leucomatous corneal opacity with superficial vascularization and an irregular anterior chamber. An iris implantation cyst encroaching visual axis was noted [Figure 1]a behind inferior iris defect causing a secondary angle closure. Anterior segment optical coherence tomography (ASOCT) showed a thin-walled fluid-filled cyst behind the iris, confirming the same [Figure 1]b.{Figure 1}

Our patient underwent Nd-YAG cystostomy and was kept on topical steroid and cycloplegic, tapered over 2 weeks. One week post operatively, the cyst size had significantly reduced and was maintained at 6 months [Figure 2]a and [Figure 2]b. The IOP at 3, 6, 9, and 11 months follow up was 14–16 mmHg.{Figure 2}

Therefore, laser Nd-YAG cystostomy should be considered in such implantation cysts approaching visual axis, which has minimal to no complications versus surgical cystectomy, especially in a phakic young patient is fraught with complications.
