This 3rd revised edition is more comprehensive and detailed to meet new
examination requirements, with new chapters on refractive surgery, contact
lenses, lasers. Also includes new material on photometry, visual acuity,
contrast sensitivity, colour vision, ultrasound, specular microscope,
fluorescence and more.This textbook has been written to help trainee ophthalmologists in their
professional examinations, covering the optical principles and applying them to
clinical situations. The subject is approached from first principles, assuming
no previous knowledge of optics. The text has been kept as logical and simple
as possible and is liberally complemented with diagrams which are designed to
be easily understood and memorised. Only the most fundamental and clinically
useful mathematical formulae are quoted. Ophthalmology examinations have
changed substantially since the last edition was written and a total rewrite of
this essential guide has become necessary. The third edition has been made more
comprehensive and detailed to keep up with these changes and maintain its place
as the standard text on optics.
