Today there are no cures for glaucoma. Both drops and surgeries work to protect your vision from further loss of vision by lowering the pressure in the eye. Now, one of the advantages of surgeries such as canaloplasty is that there’s mountain of evidence that the pressure stays low throughout the day. Whereas with drops there can be quite a bit of fluctuations during the day. Additionally, canaloplasty has the added advantage of restoring your natural drainage system and opening it up so that it can work the way it used to before you developed glaucoma.
