Mixing and matching multifocal lenses: How popular is it
Eyeworld Feb 2007
Richard Hoffman M.D., "
When deciding to mix and match these IOLs, starting with a ReZoom IOL in the dominant eye would appear to be the best strategy. If postoperatively, the patient was satisfied with their range of vision, then a ReZoom could be placed in the second eye. If the near acuity was close to satisfactory in the first eye (J4 or J3), it is probable that a ReZoom lens in the second eye would give an overall binocular acuity of (J2 or J1) that would be satisfactory through the mechanism of binocular summation. If the near acuity in the first eye was poor and could not be attributed to a small pupil diameter (amenable to laser photomydriasis), then placement of a ReSTOR IOL in the second non-dominant eye would be more likely to give adequate near acuity while the ReZoom IOL in the dominant eye could cover any inadequacies in intermediate distance from the ReSTOR eye."
David F. Chang M.D.,
Younger cataract patients have higher refractive expectations. They spend much more time at the computer and are more active at night. Finally, having never experienced a cataract, refractive lens exchange patients are more likely to complain about optical aberrations, decreased visual quality, and limited accommodative range.In these younger patients with greater visual demands, I will often start with a ReSTOR in their non-dominant eye. They receive a second ReSTOR if they are perfectly happy, because suggesting a different IOL is a way of convincing them that their glass is “half empty” rather than “half full.” If they desire better intermediate function and are otherwise oblivious to haloes, ReZoom is a consideration for their second eye. However, if aberrations and optical quality are an issue, I might recommend a Crystalens in their second eye.
