How Dr. Ryan Cazares Leveraged Profilometry and the Eye Surface Profiler to Boost Efficiency, Precision, and Patient Satisfaction in Scleral Lens Fitting
By Ryan Cazares, OD
In the realm of specialty contact lenses, precision and efficiency are paramount. Dr. Ryan Cazares, OD, has exemplified this by transforming his scleral lens fitting process by integrating the Eye Surface Profiler (ESP). This advanced profilometry technology has not only streamlined his practice but also enhanced patient outcomes.
Here are some key takeaways from the article:

Initially unfamiliar with scleral lenses during his optometry education, Dr. Cazares recognized a growing demand for specialty contact lenses upon establishing his private practice in Lafayette, Louisiana, in 2013. Through dedicated self-education and hands-on experience, he expanded his practice from a few specialty fits annually to over 70 in 2024.
A pivotal factor in this growth was the adoption of the ESP, which provides detailed 3D maps of the cornea and sclera, enabling precise, customized lens designs. This technology significantly reduced the need for multiple trial fittings, thereby decreasing chair time and improving patient satisfaction.

This Eye Surface Profiler scan is used to select a best-fit diagnostic scleral lens and to design a customised scleral lens.
“The profilometer also assures that the first diagnostic lens placed on the patient’s eye is more than adequate to obtain overrefraction and OCT if necessary. ”
Dr. Cazares also emphasized the importance of effective referral systems and staff involvement. He developed informative pamphlets featuring images of scleral lenses and diagnostic tools, including the ESP, to educate patients and referring doctors.
These materials, coupled with QR codes linking to secure referral forms, streamlined the referral process and reinforced his clinic’s brand as a leader in specialty contact lenses. By training staff to handle preliminary diagnostics, such as corneal topography, he ensured a more efficient workflow, allowing him to focus on complex fittings and patient care.
“Show your expertise and charge for it. But keep this in the back of your mind: scleral contact lens fitting can be lucrative only when you are finalizing these lenses. The more technology you invest in, the more knowledge you obtain through continuing education.”
For practitioners seeking to enhance their scleral lens fitting process, Dr. Cazares’ approach demonstrates the value of integrating advanced profilometry technology like the ESP, coupled with strategic marketing and staff training. These elements collectively contribute to a more efficient practice and improved patient experiences.
