Summary
Educating patients on visual performance with presbyopic correcting intraocular lenses is crucial. Understanding the defocus curve of pre-presbyopic and emerging presbyopic crystalline lens will provide eye care provides useful information to better educate patients on visual performance expectations after cataract surgery with a presbyopic correcting intraocular lens. Our objective will be to assess the subjective range of clear vision of a pre-presbyopic and emerging presbyopic patient population utilizing a defocus curve. A comparison of the pre-presbyopic and emerging presbyopic defocus curve to all FDA-approved presbyopic intraocular lenses will be discussed in the manuscript.
