I used my ophthalmology personal statement verbatim and got interviews to every TY program I applied to. My friends going into Derm and Rads did the same. At the time, I was exhausted from submitting my ophtho application and doing aways, and thought it would be better to get the internship application in as soon as possible. Tweak your ophtho essay if it makes you feel better, but I really don't think it makes much of a difference for TY progs, they know you career aspirations are elsewhere
