A 62-year-old presented with whitish elevation in the temporal part of his right eye, following suture-less cataract surgery. He had no history of glaucoma surgery. His best-corrected visual acuity was 20/20 with intraocular pressure of 12 mmHg. Examination showed a cystic bleb, with a negative Seidel's test, at the temporal incision site with adjacent corneal dellen [Figure 1].

Improper internal wound construction with fish-mouthing, which can be diagnosed with gonioscopy, can lead to pseudobleb formation. Patients may complain of irritation or visual disturbances with permanent wound slippage, late induced against-the-rule-astigmatism, and endophthalmitis as rare sequelae. Intraoperative mindfulness with appropriate management is warranted.
