Sir, Recurrent iris prolapse after laser goniopuncture in an open-angle glaucoma patient treated with non-penetrating trabecular surgery Laser goniopuncture on the trabeculo-Descemet's membrane may be required to treat a late rise in pressure when non-penetrating trabecular surgery (NPTS) begins to fail. 1,2 Herein we report a case of recurrent iris prolapse after laser goniopuncture and prophylactic peripheral iridotomy in a patient treated with NPTS. Case report A 22-year-old man received uneventful NPTS with reticulated hyaluronic acid implant (SK-GEL) in his left eye for open-angle glaucoma secondary to angle recession. Seven months later, laser goniopuncture was performed due to uncontrolled IOP, which was almost around 30 mm Hg. Twenty days after laser therapy, he complained of blurred vision and de-centred pupil in the operated eye. On biomicroscopy the pupil was found to be pear-shaped and de-centred superiorly. The transparent triangular SK-GEL implant was observed in the inferior anterior chamber. The IOP was 43 mm Hg. Gonioscopy showed that the superior iris root had prolapsed into the intrascleral chamber through the goniopuncture site. Goniosynechialysis was carried out to reposition the iris root through peripheral corneal incision, but the SK-GEL was left in this phakic eye. To prevent reoccurrence of iris prolapse, laser peripheral iridotomy (LPI) was performed at peripheral iris of 12 o'clock. 3
