What to do if i am blind in one eye and cataract in the other eye?

Ophthalmologist: If the cataract is causing enough of a problem that it interferes with your ability to function then cataract surgery is indicated. It does not hurt the eye to have a cataract (clouded lens) but it does interfer with clear vision. Fortunately cataract surgery has a very good success rate. Unfortunately, like any operation there can be side effects or complications that can cause major problems, .

Caution: It is always difficult for a patient to have surgery in the one and only functioning eye. For my one-eyed patients, i suggest that they are 'miserable' with their vision, before pulling the trigger and having cataract surgery. As there are always risks, if you are miserable, the surgery would no doubt be worth the risk. Having said that, the surgery is very safe and has a near 100% success rate.

Cataract surgery: Can be safely performed on patients who have only one seeing eye. The risk is no greater than in those patients who see out of both eyes. Obviously, this is much scarier for one-eyed patients, since they would have significant problems if there were complications from surgery. But cataract surgery has a very high success rate (95%).

Depends: Depends on the severity of the cataract and the risk given your specific situation. If the cataract is visually significant and the potential for improvement out weigh the risk of surgery (one risk for you is complete blindness), then Cataract surgery may be the best option for you, or Observation until the symptoms get worse may be the best option for you.

Cataract Surg. Safe: Cataract surgery (CS) is #1 cause of world blindness & most common surgery performed in world & US. Complication risk very low; best time in history to have CS. If no underlying retinal, optic nerve, brain issues, >90% achieve 20/20 vision after surgery; may still need glasses (depends on implant choice); Recommend CS sooner than later in good eye if CS needed ;more info: eyedoc2020.blogspot.com

Diagnosis needed: What is the cause of the blindness in the one eye - is it something which can affect the clarity and vision of the one with a cataract? There are tests which an ophthalmologist knows to make this distinction and predict the likelihood of good vision (or otherwise) after removal of the cataract. See a cataract specialist for this distinction and diagnosis.
