Pseudophakic crossed monovision can provide good patient satisfaction and spec- tacle independence. We have had good results with this. Conventional monovision is more popular today, and it may 'protect' distance vision and improve intermediate acuity, reducing the patient's dependence on spectacles." Dr. Ribeiro uses an approach in which she modifies monovision with monocularly induced spher- ical aberrations, which increases the depth of focus and enhances binocular vision through focus visu- al performance. In the far eye, she corrects the spherical aberration and in the near eye, she either does not correct it or she induces more. This can be combined with EDOF lenses that are more tolerant to residual error than MIOLs. Defocus curves of EDOF lenses for intermediate vision are very good, she said. "The strategy for monovision with EDOF IOLs is to target em- metropia in the dominant eye," she explained. "We see the postoperative evaluation, and if we have a good functional status, we replicate it in the second eye. If it needs more near, we can target the second eye for micro-monovision, or for even more near, we can use a bifocal in the second eye. Mix and match de- focus curves in our patients are very good," she said. "We are fortunate to have many solutions for the correction of presbyopia. Monovision is a satisfac- tory solution for select patients who cannot afford or may not be suited for MFIOLs. EDOF IOLs are suitable for micro-monovision and mix and match scenarios. The future may bring new IOL designs to further expand our options," Dr. Ribeiro said. EW References 1. Xiao JH, et al.
