How can I avoid having to wear glasses after cataract surgery?
I'm in my 30s. My doctor suggested that I need reading glasses, because I have a monovision intraocular lenses in one eye after cataract surgery, and had LASIK performed in my other eye.
As I mentioned in my previous answer to your question, there is no cure for presbyopia or Lau Hua-which is the reason why you need reading glasses.
Just for the sake of discussion, people who want to avoid wearing glasses after cataract surgery can opt for either monovision with monofocal lens implants, or multifocal lens implants.
Monovision with monofocal lens implants means that one eye is intentionally made to see clearly in the distance (with blurred near vision), and the other eye is intentionally made to see clearly for near (with blurred far vision)-without glasses. As you might imagine some people could like this while others might not. It is a compromise and people with monovision still sometimes wear glasses in certain situations eg driving at night, or reading fine print for long stretches of time.
Multifocal lens implants can give good far and near vision in each eye without glasses, but do note that halos/rings around lights at night are inevitable with the usual lenses, and some people may notice a reduction in contrast sensitivity, especially if their cataracts were very mild to begin with.
