The hole-in-card dominance test, the plus lens mimic test, and the cover/uncover test are essential tests to have high success in pseudophakic monovision. Contact lens trial is not necessary for most routine cases. Compromised fine stereopsis, decreased uncorrected distance vision of the near eye, and lack of guaranteed 100% glasses independence are three key topics for consultation with prospective IOL monovision patients. Anisometropia of 1.00 to 1.50 D works well for the majority of patients with good binocular stereopsis and contrast, although they may have more chance of needing backup readers than full monovision at the 1.75 D or more level. Conventional IOL monovision is still preferred, although crossed IOL monovision also works well as long as the anisometropia level is mild to modest and contraindications are avoided. Crossed IOL monovision is commonly applied in many situations, such as when the first eye refractive target is missed.
