files in last import of iphoto won't show

I have 700 photos in last import. When I first opened iphoto, was asked 'repair?', which I didn't. Instead I deleted 600 photos ( yes, iphoto is full : over 16000 images). I still can't see the last import or figure out how to repair now. I have restarted computer, opened iphoto holding command/option. Next option?
