I couldn't tell one way or another, but honestly didn't choose that particular system for any reason beyond that being what was on offer where I live. My very limited reading prior to surgery though would indicate that currently there is no source showcasing a difference in subjective recovery experience between TransPRK and this Smartsurface. What has been used as a source when covering the technology is mainly focused on the first three months [0], rather than longer term as you are describing and does in my opinion not actually showcase a difference between Smartsurface and TransPRK specifically [1]. Full disclosure, I only include the name of the system because it felt like an HN thing to do. It wasn't some value judgement that these machines are superior or that others are inferior.
[1] If you look at the source they are referencing, it compares TransPRK to aaPRK after three months and they were using Schwind machines, though did not clarify whether this was using Smartsurface. Very cursory search engine use tells me that this is toggleable, so an option on these machines. Even if this study did use Smartsurface though, that doesn't answer whether outcomes are different in TransPRK with Smartsurface vs TransPRK without Smartsurface. Additionally, I do not know whether this option was used in my case.
