Abstract
Purpose :
Combination microinvasive glaucoma surgery (MIGS) and cataract surgery have reported to be effective in reducing intraocular pressure (IOP) compared to cataract surgery alone. However, long-term data from clinical practice is lacking. The purpose of this study is to determine the long term intraocular pressure (IOP) and medication reduction after combination cataract and Hydrus Microstent surgery.
Methods :
This was a retrospective, single site, single surgeon study of patient outcomes with combination cataract and Hydrus Microstent surgery up to 3 years postoperatively. An Institutional Review Board (IRB) reviewed and approved this study and granted a waiver of informed consent. Eligible charts were from adults that had a diagnosis of mild to moderate primary open angle glaucoma or ocular hypertension and underwent combined cataract surgery with Hydrus Microstent with a minimum of 6 months of follow-up data available. Outcome measures included mean number of ocular hypotensive medication prescribed, intraocular pressure (IOP), and corrected distance visual acuity (CDVA).
Results :
A total of 217 eyes were identified that met the inclusion and exclusion criteria above. Mean medications improved from 2.68 ± 1.16 at baseline to 1.56 ± 1.30, 1.72 ± 1.44, and 2.02 ± 1.28 at 12, 24, and 36 months postoperatively, respectively. Intraocular pressure improved from 16.05 ± 4.64 mmHg at baseline to 12.62 ± 2.93 mmHg, 12.97 ± 3.94 mmHg, and 12.86 ± 2.48 mmHg at 12, 24, and 36 months postoperatively respectively. Mean postoperative CDVA was 0.12 ± 0.27 logMAR, 0.12 ± 0.27 logMAR, 0.17 ± 0.37 logMAR at 12, 24, and 36 months, respectively, compared to 0.22 ± 0.35 logMAR at baseline.
Conclusions :
The results of this study suggest that after combination cataract and Hydrus Microstent surgery the number of glaucoma medications is reduced and IOP is improved and these outcomes are sustained for 3 years postoperatively.
