In particular, men who take tamsulosin Flomax, generic, or similar drugs for prostate problems, require special surgical techniques to prevent complications. In patients who have cataracts plus either closed-angle glaucoma or open angle glaucoma that is stabilized with medication, the cataract may be extracted and medication continued for the glaucoma. What treatments should I expect if I begin to feel pressure building up? The effect of going from brightly lit rooms into dark ones can be more extreme and cause an even greater loss of vision.
