Although the question and answer format imposes restrictions on the orderly development and presentation of material, this book has much information of value to the novice contact lens fitter. The subject is broadly covered and touches on many diverse topics including history, corneal anatomy and physiology, contact lens manufacturing and adjustments, fitting techniques, and hydrophilic lenses. Unfortunately, the author does not distinguish between the folklore and validated observations, and the inexperienced practitioner may be misled into accepting as fact that which is actually impression and unsubstantiated claim.
A number of techniques for fitting conventional contact lenses are described in this book. They are presented as nomograms or arbitrary measurements based on anatomic rather than physiologic concepts. Since it is widely accepted that anoxic corneal edema is the most important cause of hard contact lens wearing failure, it is disappointing that the concept of venting is barely mentioned.
