Hey guys,
I am so sorry to hear about your match results. I know how heartbreaking it is, I was in your shoes last year. My recommendation to you guys is not to give up if ophthalmology is something you really want to do.
Although no one can give you the right answer, I would recommend the following...
First think about why you didnt match (Did you get lots of interviews? If yes, maybe it's something in the interview skills you need to work on. If you didn't get many interviews, was it something in the selection process? Your board scores, grades, etc.) These things you need to improve or add something more to your CV so you can stand out next year. A prelim year is not going to do that. So... Show your commitment to the field. Delay your graduation for one more year and during that year try to get into some ophthalmology research or a pre-residency fellowship at one of the more known institutions. Yes, it may not be financially compensated, but if you find a great research opportunity and a PI who will be a great advocate for you in the next year's match, it will pay off.
Now, I understand that everyone's situation is different and my advice may not work for everyone. But if ophtho is what you want, give it another try.
I hope all goes well. In the next few days try to take care of yourself because that is what is most important. Think positively
