71 years of age. Have glaucoma in both the eyes. But it is more advanced in the right eye. I also have cataract -- 50% in the right eyes. This makes it difficult for me to drive my car. The ophthalmologist I consulted advised cataract surgery in the right eye. My questions are: one, is it safe to go for cataract surgery in the eye affected by glaucoma? Second, Which surgery should ideally come first -- glaucoma or cataract or both simultaneously? Which is the safest thing to do? Third, is removal of cataract and replacement of the lens possible through laser? Where is this done?
