Because of how they work, it makes more sense to talk about a telescope's light gathering ability and angular resolution than how far it can see. If you're including a specific detector (your eyes, some CCD, whatever), you can also directly talk about the faintest objects possible.

With a big enough aperture and enough time you could see the surface of the nearest exoplanets. But that would require something with an aperture the size of the moon or jupiter.

Some of them can be seen with smaller telescopes: https://en.wikipedia.org/wiki/List_of_directly_imaged_exoplanets
