Can you get rid of cataracts without having surgery?

No. Cataracts never clear up by themselves and there are no known medications, laser treatments etc to make them clear. The only way is to remove them with surgery.
No. Not at this time. There has been no proven medication to reduce cataracts. Theoretically if you dilate someone, you could potentially "see around" a focal cataract.
Slow the progression. You can not reverse or cure cataracts without surgery, but you can slow the progression. 2 well-known factors are smoking and exposure to ultraviolet light. So....One more reason to quit (if you are a smoker)! and make sure you wear sunglasses and hats to shield your eyes from u-v light.
