It is always best to discuss the timing of cataract surgery with your experienced cataract surgeon at the Northern Eye Centre. This will depend on your individual needs and lifestyle circumstances.
You can wait for a while if the cataract is not giving you trouble, so long as you are safe and can achieve your life demands with no visual handicap, in particular if you are safe to drive.
If you start to have problems, then it is reasonable to consider surgery. The operations for cataract have improved tremendously over the last 20 years and are now considered to be one of the safest and most satisfying surgeries anyone can go through. It is by far a gratifying experience. You always need to discuss the benefits and risks of the surgery with your eye specialist before going ahead.
Your age is not a deterrent to going ahead with surgery as it is done under regional anaesthesia as a day surgery case.
