Description

CHAPTER 4. DIAGNOSTIC APPLICATIONS OF WAVEFRONT SCIENCE (86 pages)
Description:
Wavefront science is explored for its diagnostic applications in refractive care as well as evaluation and diagnosis of ocular surface and corneal irregularities. These applications are unique and new to primary eye care.
Course Outline:
1. Diagnostic Applications of Wavefront Science
A. Advantages of routine use of wavefront (on every patient):
1. Additional diagnostic information
2. Screens for subclinical, subtle, early, insidious pathology
3. Saves clinician’s time in diagnostic evaluations
4. Valuable and effective patient education tool
B. Disadvantages:
1. Too much or more than needed information (“overload”)
2. More sensitive than AR to patient s’ eye movements
3. Not reimbursable (unless through added charge to patient)
C. Vision care
1. Refractive care
a. Routine refraction (as an autorefractor)
b. General visual and ocular screening
c. Identifying photopic and scotopic refractive differentials
1) Simultaneous autorefraction and aberrometry with controlled pupil diameters
a) 2.6mm photopic (aurorefractor)
b) 4.0mm mesopic/scotopic (aberrometer)
2) Refines the lower order refraction
3) Aberrometer does all the calculations
a) Gives the doctor (and patient) multiple options
b) Best lower order correction for bright, day vision (small, photopic pupil)
c) Best lower order correction for dim or dark, night vision (large, scotopic pupil)
d. Assessing static versus dynamic visual differences
2. Wavefront customized
3. Eyes not correctable to 20/20
4. Dynamic (accommodative) vision
D. Eyelid abnormalities and effects
1. Blepharoptosis
a) Induced coma and trefoil
b) Reduced by blepharoplasty
2. Chalazion
a) Induced coma and trefoil
b) Reduced with chalazion removal
3. Others eyelid “lumps and bumps
E. Ocular s

Objectives

Objectives
1. To introduce wavefront science as a diagnostic tool in vision
2. To introduce wavefront science as a diagnostic tool for the ocular surface and cornea
3. To provide methods and procedures to analyze refractive information at the lower and higher orders

Wavefront has been evolving as a clinical science in eye care for the past 20 years now. It started with refractive surgery in the 1990s when I became involved with it and it has been growing rapidly as a vision and eye care diagnostic science as well ever since. I published this textbook in 2009 with the goal of converting the complex mathematical and optical physics of wavefront science into understandable clinical, diagnostic and non-surgical and surgical corrective approaches for day-to-day practitioners’ use. The story is told over 6 chapters in a casual, ‘user friendly’ style with extensive graphic support. It’s actually an enjoyable – almost a fun read. An extensive 30 page Subject Index is available on this website at no charge for referencing and/or downloading (as a pdf file) at the program entitled Wavefront Science in Vision and Eye Care: SUBJECT INDEX (LINK: http://wco.easyshare.education/by/dr-louis-catania/128075/wavefront-science-in-visio-and-eye-care-subject-index). And finally, under Additional Course Notes section, the Front Matter from the textbook is available. It includes:
> Table of Contents (general and detailed);
> Preface;
> Acknowledgements;
> Introduction

Author Bio:
> Internationally acclaimed clinical educator, author;
> Recognized expert in anterior segment, corneal disorders, refractive surgery and new eye care technologies;
> With Nicolitz Eye Consultants, a multispecialty ophthalmology group in Jacksonville, FL;
> Does clinical research on numerous eye care technologies;
> Voted one of 10 most influential optometrists of 20th century by the Review of Optometry Journal and 20/20 Magazine;
> 2013 Distinguished Service Award from the Ocular Surface Society;
> 2014 Distinguished Service Award from the American Academy of Optometry;
