PurposeTo evaluate the intraocular pressure (IOP) reducing effect of cataract operation combined with either trabecular bypass microstent (iStent) implantation or internal trabeculectomy (Trabectome).MethodsA retrospective interventional case series involving 61 eyes who underwent cataract surgery combined with either iStent implantation or Trabectome. Outcomes included short term (1–3 months) and long term (6–12 months) changes of intraocular pressures and number of glaucoma medications.ResultsFor all cases, mean preoperative IOP of 19.9 ± 5.2 mmHg decreased by 17% to 15.8 ± 4.9 mmHg short term and by 12% to 16.4 ± 3.73 mmHg long term. For iStent cases, short term and long term IOP reduction was 21.7 and 17.7%, respectively (from 20.6 ± 6.3 mmHg to 15.2 ± 3.3 and to16.5 ± 3.8 mmHg). For Trabectome cases, short term and long term IOP reduction was 14.6 and 10.5%, respectively (from 19.5 ± 4.5 mmHg to 16.2 ± 5.7 and to 16.4 ± 3.8 mmHg). Long‐term IOP changes were significant in both subgroups (p < 0.005). There was no significant change in the number of glaucoma medications in either groups (2.0 ± 1.1 preoperative, and 1.7 ± 1.3 long term postoperative for all cases, p = 0.09.)ConclusionsCataract surgery combined with iStent or Trabectome provided a significant but only modest reduction in intraocular pressure.
