Not a Delta guy so can’t answer your question directly. I have already done both eyes (52 years old!). Procedure is easy and results are pretty amazing. Only info I can add is double check the lens. Basic monofocal lens was covered for me.

Newer lens technology was not covered but gave credit for cost of basic lens. Symfony lens looked very intriguing but my eye doc and two AMEs I reached out too did not recommend it for pilots.
