Before you do anything read this article CAREFULLY: https://www.medhelp.org/user_journals/show/1648102/Consider-ALL-the-Options-Before-Your-Cataract-Surgery-Working-Through-Whats-Best-For-You--2019-2020-Update
My biggest concern is that you are aiming to set both eyes for distance (20 ft or 6 m) so the far RX after surgery would ideally be 0.00 You would not see clearly at distances less than 20 ft. So you would need glasses to see TV at 10-15 feet, be unable to read, use computer, shop. So you would be wearing no line (progressive) multifocal glasses most or all of the time. Granted you might be able to read with over the counter reading glasses but you would need a different pair for shopping and computer and only a custom lens for TV and intermediate. I have many patients that consult me with surgery done elsewhere unhappy with this. A better solution described in the article for most people would be mini-monofocal distance bias that is -0.25 for dominant distance and -1.00 for non-dominant eye.
The cornea problem you have is also called basement membrane disease. It is common and often assymptmatic. Generally it does not interfer with the pre-op tests for implant measurements. I strongly suggest you discuss your targeted post op refractive error with your surgeon.
