For each patient, one eye underwent single-site rigid probe viscotrabeculotomy (Group S: 35 eyes) and the fellow eye underwent double- site rigid probe viscotrabeculotomy (Group D: 35 eyes). At one-year follow up, complete success was defined as IOP &gt;5\u2005mmHg and \u226416\u2005mmHg without any further IOP-lowering medications and qualified success when IOP \u226416\u2005mmHg with using IOP-lowering medications. Failure was defined as IOP more than 16\u2005mmHg despite the use of IOP-lowering medications, the need for other glaucoma surgery to control IOP or hypotony.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Single-site rigid probe viscotrabeculotomy showed a one-year complete success rate of 88.57% and for double-site viscotrabeculotomy was 91.43% but the difference was not statistically significant (p-value 0.9).
