The Laserfit lens process with wavefront-guided optics is now in its fourteenth clinical year. In October 2022, Dr. Gemoules presented his most recent updated scientific information on the process he developed to a group of colleagues who gathered in Sorrento, Italy in October, 2022. That presentation is now available here in the link below. The presentation includes the statistics on how much vision improvement is possible with Laserfit lenses for patients who suffer from keratoconus and further demonstrates why Laserfit is still the leading lens solution for patients with elevated higher order aberrations. The presentation also includes some interesting slides which further demonstrate the powerful capabilities of LASERFIT.
SUMMIT LECTURE 2022
We have now just updated that information with the latest 52 consecutive keratoconus eyes with this new slide. Using a histogram it is easier to demonstrate what the typical patient can expect in the way of improvements in the higher order aberrations as compared to lenses using standard sphero-cylindrical optics. More than half will see improvements in the 70-80% range, followed by 60% for approximately one-third of patients and one-fifth will see 50% or less improvement in HORMS. This documents that we have achieved in a clinical setting what was only possible in a controlled academic research environment in the past. This patient cohort does contain a few patients with various degrees of corneal haze secondary to keratoconus and crosslinking. Two eyes representing the lowest and highest data points (outliers) were also excluded.
Equipment Upgrades
In 2024 Dr. G. traveled to Boston to demo and subsequently purchase the Heidelberg ANTERION which was shown at the ASCRS meeting. The ANTERION is the newest in swept-source OCT technology for measuring the anterior surface of the eye and the cornea. It was only recently approved in late 2023 for purchase in the U.S., and signifies the very first opportunity to upgrade and replace our tried and true Visante from Carl Zeiss. Laserfit can continue to move forward with the latest in eye scanning technology. Because the results are so similar, we can continue to use the VISANTE alongside the ANTERION in our operations while having a backup system in place. The ANTERION will provide us with new opportunities that always come with new technology.
As with the VISANTE, the LASERFIT process requires that the ANTERION scans be processed with custom software to enable the scans to be imported into the computer-aided-design environment. Once that had been completed, Dr. G. was able to compare lenses made with Anterion scans with those made with Visante scans on the same patient to measure the results. One particular case involved a patient who had undergone scanning with the Visante and had been successfully fitted with lenses more than a decade ago. The result was that the lenses made from two different scanners with completely different technology from two different companies, and scanned 12 years apart, were virtually identical in shape and fit as indicated by the CAD software.
