AIM: To investigate the safety and efficacy of the Zeiss Visulas II diode laser system in the reduction of intraocular pressure (IOP) in patients with complex glaucoma. METHODS: The authors analyzed the medical records of patients who underwent transscleral diode laser cycloablation (TDC) at the Manchester Royal Eye Hospital during a 34-month period. Fifty-five eyes of 53 patients with complex glaucoma were followed up for a period of 12-52 months (mean, 23.1 months) after initial treatment with the Zeiss Visulas II diode laser system. RESULTS: Mean pretreatment IOP was 35.8 mmHg (range, 22-64 mmHg). At the last examination, mean IOP was 17.3 mmHg (range, 0-40 mmHg). After treatment, 45 eyes (82%) had an IOP of between 5 and 22 mmHg; in 46 eyes (84%) the preoperative IOP had been reduced by 30% or more. The mean number of treatment sessions was 1.7 (range, 1-6). At the last follow-up appointment, the mean number of glaucoma medications was reduced from 2.1 to 1.6 (p < 0.05). In ten eyes (18%), post-treatment visual acuity (VA) was worse than pretreatment VA by two or more lines. CONCLUSIONS: Treatment with the Zeiss Visulas II diode laser system can be safely repeated in order to achieve the target IOP. Treatment outcomes in this study were similar to those from previously published work using the Iris Medical Oculight SLx laser.
