iPhoto import from iPhone. How to keep changes?

Hi,

I'm using my iPhone 4s for taking photos. I'm often editing this photos in my iPhone (mostly optimize it or cut it).

After connecting with my laptop, the automatically export from iPhone to laptop's iPhoto occurs, but all the imported photos are in the original condition.

If I import photos from iPhone to Facebook, it appears including the changes. If I import them to my laptop, the changes are gone..

How can I save/import my photos to my laptop including the changes? Thank you!

I'm using MacBook Pro (Retina, 13-inch, Mid 2014), 256GB SSD (115GB free), 2.6 GHz Intel Core i5, 8 GB 1600 MHz DDR3, Intel Iris 1536 MB

OS X Yosemite, ver. 10.10.2, iPhoto ver. 9.6.1 (910.42). I'm using iPhone 4s.
