That they are no better than multi-focal contact lens (and I have Another sister who hated THEM! The dr said with monovision my middle distance may suffer and I told him it doesn't now with monovision contacts.He said that's because my eye still has some flexibility to adjust but the replacement lenses won't have that.Effective IOL implants also entirely eliminate the need for glasses or contact lenses post-surgery for most patients.The cataract will not return, as the lens has been removed.More commonly, aphakic IOLs (that is, not PIOLs) are implanted via Clear Lens Extraction and Replacement (CLEAR) surgery.

But today a pharmacy tech I spoke with threw a wrench into my plans because she has monovision and loves it.
Most IOLs fitted today are fixed monofocal lenses matched to distance vision.
However, other types are available, such as multifocal IOLs which provide the patient with multiple-focused vision at far and reading distance, and adaptive IOLs which provide the patient with limited visual accommodation.
