I'm an Ophthalmologist. Pay ranges from $200-300k starting, 350-700k as a partner, depending on region and practice setup. Retina pay is much higher. Yes, matching Ophtho is indeed quite competitive. If you're really dedicated and express interest from the start, however, it isn't that bad.
What do you mean by surgical Ophtho? Pure cataracts? Almost impossible to find as a gig, but yes that will easily stay under 45-50 hrs/week and pay insanely well. Comprehensive Ophtho with 1-2 days in the OR will pull the above figures and be under 45-50 hrs a week.
Call in Ophtho is very minimal. Retina used to have it bad in regards to that, but now it's barely a worse lifestyle than comprehensive.
As
Neopolymath said, the sky is the limit if you know what you're doing in business.
Also, compared to other surgical residencies, it's pretty cush. Second year can be bad, but 3rd and 4th year typically come in at or below 60 hours a week.
