There’s absolutely zero importance. Surgical retina match has become fairly less competitive than before. There were tons of open spots last year. Maybe because cataract/refractive/migs (comp) can be fairly lucrative with a better lifestyle? Who knows. Ofc the fellowships at top places will always remain competitive - so residency prestige, letters, and research will matter much more at these places.

I’ve never heard of jobs asking for okaps scores.
