Other than cataract surgery with lens implantation, there are actually no other surgical or non-surgical options to treat cataracts. However, even if recommended by your doctor it is always your choice whether or not to have surgery.
While the cataracts will not permanently damage your eyes, they obstruct your vision. In some cases adjusting your eyeglasses may provide temporary improvement. However, over time the cataract will generally cause a gradual decrease in vision.
Furthermore, removing the cataract is not an emergency, like other surgeries that must be performed to save your life. Therefore, waiting for a better time, or until you are more ready for surgery, is also an option.
A cataract should be removed when your vision loss significantly affects your work or lifestyle. Due to the safety of modern cataract removal, the surgery can be performed at any time. Although, excessive delay of cataract surgery may result in a greater chance of complications, which can ultimately lead to poorer vision after the surgery.
The final decision whether or not to have surgery rests with you, but all concerns relating to this decision should be discussed with your doctor at length. Then you and your doctor can come up with a treatment method that is comfortable for you.
