PURPOSE: To study the complications of neodymium:YAG (Nd:YAG) goniopuncture after deep sclerectomy with collagen implant (DSCI). METHODS: All patients who underwent an Nd:YAG goniopuncture after a successful DSCI for primary open-angle glaucoma were included in a non-randomized clinical study. RESULTS: Nd:YAG goniopuncture was performed in 31 patients. The mean time from surgery to goniopuncture was 3.2 ± 3.2 months. The mean intraocular pressure (IOP) before goniopuncture was 32.0 ± 10.8 mmHg (SD); the mean IOP one to two hours after goniopuncture was 16.5 ± 6.3 mmHg. After a mean follow-up of 5.4 ± 2.8 months, mean IOP was 17.8 ± 11.6 mmHg. Three patients had a spontaneous iris prolapse after Nd:YAG goniopuncture and consequently high IOP. No signs of severe hypotension were observed. CONCLUSIONS: There are potentially serious complications relating to Nd:YAG goniopuncture after deep sclerectomy. However, further studies are needed to determine the safest time and level of IOP at which to perform Nd:YAG goniopuncture.
