WHAT DO THE EXPERTS THINK? PART I

I I have been asked many times-- what is your favorite soft lens? Which soft lens disinfection system do you recommend? What rigid gas perme- able lens do you prescribe? It is always a pleasure to give my per- sonal opinions regarding contact lens care. But, I thought the readers of ICLC should hear from the contact lens "experts". So, I designed a survey to analyze the economics of contact lens practice, the prefer- ences in contact lenses, and lens care products.

A Diplomate of the Cornea and Contact Lens Section of the Ameri- can Academy of Optometry is recog- nized internationally as an expert in contact lens care. Diplomate status requires:

1. Admission to Fellowship in the American Academy of Opto- metry.

2. Oral, written, and clinical ex- aminations on contact lens care.

3. Presentation of detailed contact lens case reports.

Currently there are 178 diplomates of the American Academy of Optometry Cornea and Contact Lens Section. One hundred and forty seven (83%) diplomates were sent a contact lens questionnaire. The questionnaire was not sent to doctors who have retired from active practice. I received responses from sixty (41%) diplomates. This month I will give the results regarding soft and rigid contact lenses.
