The book is an essential undergraduate reference work known by its former author O'Connor Davies. The text has been substantially revised and the contents updated. New sections on general principles, diagnostics, contact lens solutions, legal aspects and ocular side effects have been included, as well as new colour illustrations, and there is a new and greatly expanded therapeutics section, bringing it thoroughly up-to-date with the latest trends in optometric practice. With a re-designed format and new and improved illustrations, this long awaited edition will be invaluable to optometry students, pharmacists and ophthalmologists.
