Eyehow – Digital Refraction – Is it Better?

We have done several posts about the benefits of digital freeform lenses and most recently we discussed advanced inspection techniques and measurements. But we haven’t talked much about the benefits of digital refraction or relationship to each other.

More and more practices are selling digital freeform lens technology because they understand how the advancement in lens design can help patients achieve their best vision.  However, many of the same practices that prescribe the digital freeform lenses still refract their patients with older technology.  We are not saying this is bad but ask the question is digital refraction better?

I asked one of our sponsors Visionix about it as this is a company that develops, manufactures and sells wavefront-based technology most specifically PowerMap™, which provides simultaneous multipoint measurements of all the parameters of a lens. Plus we know that Marc Abitbol, CEO of Briot and Visionix is a pioneer in this area.

“In order to get the very best acuity from a freeform lens style, the method of refraction itself needs to be examined.  With the new Wavefront Digital Refraction Technology based on designs by Visionix Inc., subsidiary of Luneau Technologies, eye care providers can now refract more precisely than the historic quarter diopter measurements heavily relied on in the past.  With greater precision and understanding that a patient’s prescription changes in different environments, vision correction is now offered as fully customizable to each individual when the doctor uses the latest technology not just in lenses prescribed, but in the method of refraction itself.

Additionally, the WaveLens Pro, a Visionix exclusive wavefront based lens analyzer, helps to ensure accurate prescriptions are coming back from your lab.”

Matt Cevasco, President and GM Briot USA and Visionix says “Increasing numbers of optometrists say that the part of their job they like the least is refraction. They tell us they would rather work on diseases of the eye.

This is a tool for them to make the refraction process more effective and efficient. It allows super-accuracy while also being easy enough to use that it can be completed by a skilled technician. I can teach anyone how to use it in 10-15 minutes. Simplicity, accuracy and speed lead to patient satisfaction and better overall experience in the practice. We’re starting to see a major shift away from the traditional way of doing refraction which has been with us for the last 100 years. Wavefront technology has given us a way to obtain a more accurate objective refraction. This system allows the ECP to refract at the most precise level possible. The doctor in the exam room can now match advances in lens technology, which makes for a more satisfied patient.”

What are you doing as far as digital refraction, have you made changes, if so what are they? We would really like to hear from you on this subject and share ideas.

  1. I definitely think that more and more people are getting savvy about their lenses. There is a lot of information out there and most opticians are seeing first hand the investigation and research some patients have done. Especially those with very high minus or specialty prescriptions. When offering your patient a customized lens, I think it only makes sense that in order to get the best of the technology, the practice should refract with the best technology. In turn, the practice will see happier patients, less non-adapts, and that makes EVERYONE happy.
