Have lived with open angle glaucoma for about 20 years . Using Latanaprost ( Xalatan ), Restasis ( for dry eye ) and Combigan ( Pressure ). I just changed from Restasis to Xiidra for dry eyes. Of all the drops I have taken Combigan does the most to hold my Inner Ocular Pressures ( IOP ) down.. Fighting Chronic dry eye while using these drops seems to always be an issue it is not the end of the world. Glaucoma can be slowed and controlled if seen regularly like every 3 months because you want to keep track of any progression and the limit any damage done by not mitigating this disease. It is totally treatable and no need to panic. See your DR. and follow their directions . No slacking . LOL. Just had cataract surgery 2 days ago on my right eye and so far so good. Will schedule the other eye soon. You take good care and do not worry about your Glaucoma diagnosis. You will be fine. Stay Safe.
