Last Minute Optics is by Hunter and West. It is a Q&A format so better for review than for building a foundation.
David Guyton's book is called Ophthalmic Optics and Clinical Refraction. He is developing the course on a CD and should be available next year. I just spent 16 hours being lectured by him last week...he is a phenomenal teacher! His book is $17.50 sent to:
David L. Guyton, M.D.
Wilmer Institute, 233
Johns Hopkins Hospital
Baltimore, MD 21287-9028
The AAO BCSC book Section 3 is highly recommended as are Optics for Clinicians by Rubin and Clinical Visual Optics by Bennett and Rabbetts.
