Corneal abrasion and healing

I suffered a corneal abrasion one week ago. My vision is still slightly blurred and lights are slightly streaked (astigmatism?). I can read and use the computer just fine, the blurring is not enough to keep me from doing that, but still noticeable. I look at a point light source, and I can see a slight streaking effect. The eye has no visible symptoms - no redness, no swelling, no puffiness, etc. It is tender and drys out easily, and I tend to keep it closed part of the time. My eye doctor (optometrist) examined me twice, put dye in the eye and used a slit lamp microscope thing. She said the eye was healing nicely, abrasions were healed over.

Is this normal to still have some discomfort and drying after a week? How long do these symptoms normally last? Do vision changes like this eventually go away? And lastly, how long should I wait before going back to my eye doctor if I'm still having discomfort or vision changes don't go away? (Or should I have seen an ophthalmologist instead?
