When I started in ophthalmology in the 1970s, the standard and only thorough text on the cornea was the 1965 volume VIII of Duke-Elder's System of Ophthalmology. That remarkable book is still useful for its depth of historical literature review and clinical disease descriptions but is of almost no value for medical and surgical therapy. There have since been several additions to the cornea textbook range. Smolin and Thoft's text was first published in 1983 as a relatively small book written by Massachusetts Eye and Ear Infirmary Cornea Service faculty and alumni. It has since expanded greatly but still represents the “Boston school” of cornea and external disease.
