The Mayo Clinic has a very interesting Webinar video on their experience with the LAL - "Light Adjustable Lens - What every ophthalmologist should know"
https://medprofvideos.mayoclinic.org/videos/light-adjustable-lens-what-every-ophthalmologist-should-know-webinar
A couple of interesting points in the video:
7:40 - They present statistics that show 80% of mini-monovision (blended vision) patients get 20/20 vision for both near and far, compared to only 40% using PanOptix multifocal lenses.
23:14 - A graph is shown for the patient selected steps in refining the near vision target refraction. the large majority select -1.3 to -1.5 D.
To me this Mayo Clinic experience confirms that that target for mini-monovision of -0.25 D distance and -1.50 D are optimum. This is what patients select that have 3-4 do-overs to finalize their choices.
I have never seen any credible information that there is a requirement to have one eye close to plano. The brain is quit adept to selecting the best image from what is available to it. Studies have been done on using the dominant eye vs the non dominant eye for distance vision. While the convention is to do the dominant eye for distance, some have suggested the reverse, crossed monovision, is better. My conclusion is the brain sorts it out.
