PURPOSE: To prospectively evaluate the intraocular pressure (IOP) lowering ability, retreatment rate, and complications of transcleral Diode laser cyclophotocoagulation using a higher power setting than what is generally recommended. PATIENTS AND METHODS: A total of 36 eyes of thirty six patients with refractory glaucoma, and who fitted our inclusion criteria underwent Diode cyclophotocoagulation. The laser power was set at 2250 mW, with a duration of 2000 ms, and a total number of 28 shots for the first treatment and 20 shots for any consequent one. The patients were followed up for 1 year with the following outcomes being analysed: IOP, visual acuity, change in the number of medications, and complications. RESULTS: The mean IOP decrease was 53% (P < 0.05), and 72.2% of the patients maintained an IOP ≤ 21 mmHg for the whole duration of the study The number of medications necessary to control the pressure, significantly dropped from 2.8 to 0.89 (P < 0.05), and 25% of the patients needed the treatment to be repeated only once.In all, 33% of the patients improved their visual acuity after the treatment, while 22% worsened, and the rest stayed the same. The most common treatment complications were conjunctival injection and corneal oedema, and these were both transient and reversible. CONCLUSION: The use of the higher power setting of 2250 mW, resulted in a sustained lower IOP, less use of medications, less need for retreatment, relative preservation of visual acuity, and only reversible complications.
