Many elderly patients have both glaucoma and cataracts, how exactly should they be treated to improve their vision? The eye is like a camera, cataract is equivalent to a damaged lens and glaucoma is equivalent to a damaged film. A problem with either one will result in a poor picture, or loss of vision. Before deciding on a treatment plan, doctors must first determine whether the poor vision is caused by problems with the “lens” or the “film”, which is the main factor, and whether there is a correlation between the two. Each has its own approach, but one thing must be known, as far as the current level of medicine is concerned, the “lens” can be replaced, while the “film” can not be repaired, but only to control the speed of progress. Therefore, glaucoma needs to be detected and treated early. When it comes to the specific treatment, it needs to be individualized. Some patients can be treated for cataracts and glaucoma at the same time, while others must have both surgeries, either in combination or separately.
