Are Multi-focal implants my only option to read without glasses after cataract surgery?
Certainly not. You could elect to have your implants set for monovision. This means that you would see well far away with one eye and close-up with the other. Again, you would be relatively free of glasses but would lose some of your depth perception - potentially making driving and activities such as golf a problem. Monovision also sacrifices some of the clarity in your vision because you are only using one eye for each distance. Thirdly, as you only have two eyes, monovision has the disadvantage of only allowing focusing at two distances (usually near and far away).
In contrast, the Multi-focal implants allow you to use both eyes so they do not compromise your depth perception. In addition, with Multi-focal implants, you can see well at all three distances: near, intermediate and far.
