The therapeutic effect of Lanomax® varies greatly depending on the type of cataract and the degree of progression of the cataract. Generally, in the case of incipient, immature, and mature cataracts, if you administer two vials of Lanomax® eye drops to one eye for six weeks, you will see visible improvements compared to the untreated eye. Sometimes there are dramatic cases where a visible effect is even noticed within a short period of 1-2 weeks after beginning to administer Lanomax®.
