If you are looking for more education I would try the JCHAPO/AAOE OCS certification it is all about eye coding and billing.
I am a fan of Corcoran Consulting Groups events and whitepapers on ophthalmology coding and billing.
I also like the ASOA for both their certifications CPSS for front desk staff and the COE for practice managers. Their ASOA Learning Center is a really great practice resource
I also like BSM Connection for Ophthalmology their elearning center is well done for administrators and ophthalmic practice operations and overall staff training.
Hope this helps
