Many patients who undergo cataract surgery have both eyes corrected for emmetropia with monofocal IOLs and rely on spectacles for their intermediate- and near-vision tasks. However, there are also several surgical strategies for correcting presbyopia at the time of cataract surgery currently available in the United States. These strategies include pseudophakic monovision, accommodating IOLs, multifocal IOLs, and EDOF IOLs. Table 9-2 lists several examples of presbyopia-correcting IOLs currently available in the United States.
Pseudophakic monovision is a surgical technique in which different refractive targets are set for each eye. Typically, the dominant eye is targeted for emmetropia. The fellow eye is targeted for some degree of myopia. The term modified monovision (or mini-monovision) refers to a milder myopic target (eg, −0.50 to −1.50 diopters [D]), compared with “traditional” monovision (−1.50 to −2.50 D).
