That is the exact point- since the implanted lens cannot be stretched and reconfigured for various distances like the native biological lens, every patient will have to choose whether to wear glasses for reading or far-sighted activity, because the artificial lens will not do both. The results are amazing, as you mentioned, and many patients do have 20/20 vision or better, but most will have to either wear reading glasses or glasses for far-sighted activities since the implanted lens cannot reconfigure for both visual functions. Most ophthalmologists I work with will ask the patient if they would rather have a lens that requires reading glasses or one that will require corrective lenses for far-sighted functions- the implanted lens cannot accomodate to both like the biological one it replaces.
