Intraocular pressure (IOP) and IOP-lowering medication use were recorded at baseline and each postoperative visit through up to 24 months. Primary outcomes were reductions in IOP and medication use from baseline; secondary outcomes were the proportions of eyes achieving IOP reductions of ≥ 20% and medication reductions ≥ 1 medication from baseline. Subgroup analysis was conducted in eyes with high and low baseline IOP.Results: Data from 44 eyes of 32 Latino patients with OAG were analyzed. Mean IOP was 17.8 (0.7) mmHg at baseline and postoperatively ranged from 12.4 to 13.8 mmHg (p≥ 0.0003), representing mean IOP reductions of 4.2– 4.6 mmHg (19.7– 23.1%). Mean medication was 1.5 (0.2) medications per eye at baseline and postoperatively ranged from 0.2 to 1.0 (p≥ 0.0061), representing mean medication reductions of 0.7– 1.2 medications per eye (47.1– 87.2%). In the low baseline IOP group (< 18 mmHg), mean IOP was significantly reduced through Month 24 and medications through Month 12; in the high baseline IOP group (≥ 18 mmHg), IOP and medications were significantly reduced through Month 24. From Months 1– 24, IOP reductions of ≥ 20% were achieved by 48.4– 56.2% of eyes in the full cohort, by 20.0– 33.3% in the low IOP group, and by 66.7– 100% in the high IOP group; medication reductions of ≥ 1 medication were achieved by 72.0– 95.6%, 64.7– 94.2%, and 87.5– 100% of eyes, respectively.Conclusion: Combined KDB-phaco in eyes of Latino patients with glaucoma and cataract significantly lowers IOP and the need for IOP-lowering medications for up to 24 months and should be considered for such patients who warrant IOP reduction, medication reduction, or both.Keywords: glaucoma, intraocular pressure, excisional goniotomy, Kahook Dual Blade, Latino

Silicon carbide fiber reinforced silicon carbide matrix composites (SiCf/SiC) have been identified as a material with high-performance mechanical properties for the aerospace industry. Microwave-enhanced (ME) chemical vapor infiltration (CVI) heating of ceramic matrix has been proposed as an efficient production technique having the potential to yield near fully dense SiCf/SiC composites in a significantly shorter time span. This paper presents some results of computational analysis of electromagnetic and thermal characteristics of the ME CVI process carried out with thin SiC discs in a Labotron microwave system from SAIREM. The simulations are aimed to clarify multiple unexplained observations in experimental work through understanding causes for the formation of microwave-induced temperature fields. Resonant and non-resonant frequencies of the experimental system for different temperatures of the processed SiC sample are analyzed to explain the difference in heating rates. 3D temperature fields inthe SiC preforms at different frequencies are also presented. It is shown that, after being non-uniform in the beginning of the process, temperature patterns evolve to quite homogeneous ones by its end. The results suggest a means for better control of the equipment to pave the way to more efficient implementations of ME CVI the hence the less expensive and high quality SiCf/SiC composites.
