There’s a fine balance when it comes to deciding the perfect timing for cataract surgery.
You are right that we shouldn’t delay too long because in some cases, if the cataract progresses too rapidly, it will become too dense or hard; and may make the surgery more complicated or difficult, which in turn may affect visual outcome.
Having said that, very often if the cataract is progressing rapidly, it will likely affect your vision significantly, and you would be able to sense it.
On the other hand, we do not want to rush into having surgery when your vision is hardly affected.
A key consideration before surgery is how much of your vision is affected by the cataract. Remember that every surgery has some risks albeit low, so we do weigh the benefits of doing surgery against any potential risks.
I would definitely encourage surgery if your diminished vision is affecting your quality of life; however if you are functioning very well and happily at the moment, then there would be no need to rush into surgery.
In your case, because you mentioned that your vision is not affected much yet, it would be reasonable to monitor your cataracts for now.
You should visit your eye doctor regularly at least 6-monthly to check on the cataract progression.
In addition, visit your eye doctor immediately if you should experience any noticeable deterioration in your vision.
I hope this was helpful to you.
Yours truly
