Optometrist and ophthalmologist co-managing patients

In an ophthalmology practice where the ophthalmologist partners with
an optometrist to care for patients, is this usually the set-up:

Optometrist provides general eye exams and prescribes and fits glasses
and contacts, and treats simple eye conditions, and provides post-op
care
Ophthalmologist performs surgery, and treats complex patients with
complex disease

Am I correct?
