NASA technology for Webb’s telescope mirrors has increased the precision of LASIK eye surgery technology

Today’s LASIK surgery – guided by the iDesign refraction studio system – includes more than 1,200 measurements for individual vision correction that is also fast and safe.

People around the world have been amazed by the amazing images displayed by the “James Webb” space telescope and are characterized by clear precision, and this telescope is scheduled to show us more images with its powerful large mirrors that reflect parts of the light from catch some stars and stars. the first galaxies in the universe that roamed space more than 13 billion years ago.

Many observers of scientific events in the world wondered about the feasibility of wasting billions of dollars on such work, and what would return to humanity at a time when millions of people worldwide suffer from extreme poverty and starvation.

To answer some of their deplorable questions, NASA published a report confirming a well-known fact, namely that space technology in all its stages has developed human knowledge, and many other technologies in all walks of life, including medical technology , and the design of medical devices that diagnose and treat many diseases. .

In fact, the space agency’s work often benefits people on Earth. For example, Web mirror measurement technology has improved the accuracy of eye surgery using LASIK, and the new technology developed by NASA scientists and engineers during the preparation and development of the James Webb Space Telescope has helped more than 18 million successful LASIK -operations, and is currently available to ophthalmologists in 47 countries around the world.

Technology improves eye surgery

The technology developed as part of the decades-old effort to build the James Webb Space Telescope has already improved the vision of millions of people who have regained good vision through major improvements in LASIK eye surgery technology.

Lasik surgery is a type of ocular refractive surgery, which has achieved good results, and complications leading to vision loss are rare.

Part of the measurement process for Webb’s mirrors is integrated into the iDesign Refractive Studio, a Johnson & Johnson Vision device that takes precise eye measurements to diagnose defects in the visual pathways and curvature of the cornea.

iDesign is the latest generation in specialized LASIK treatments, and is the only technology that uses an advanced built-in topographic approach to correct vision and map the entire corneal surface. The system also maps the entire optical path, measuring lower and higher order aberrations using approximately 1,257 data points to capture the most subtle distortions.

Together, these two detailed measurements allow LASIK treatments to be tailored with previously unattainable precision, and this system will help patients over 45 see both near and far after LASIK surgery.

A unique optical fingerprint of each patient’s eye

One executive at Johnson & Johnson Vision described the resulting information as a “unique optical fingerprint of each patient’s eye,” and iDesign’s refractive studio technology has contributed to the success of more than 18 million LASIK procedures worldwide.

The technology began in the early 2000s, when New Mexico-based Wavefront Sciences, a NASA subcontractor, worked to develop a system to measure aberrations in the mirrors of the James Webb Space Telescope as they were polished.According to accurate specifications.

“Mirrors were a very important technology that we had to develop to make the observatory possible,” said Lee Feinberg, optical telescope component manager for the James Webb Space Telescope at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. What we wanted…we had to match the curvature of one mirror to the other, and that was a very difficult problem.”

Wavefront Sciences has combined some of the algorithms it developed for the James Webb Space Telescope’s mirrors into a commercial product called the Complete Eye Analysis System, which can diagnose eye conditions by mapping the cornea.

This technology was modified several times, and introduced to the refractive studio system iDesign before it was acquired by Johnson & Johnson Vision in 2017, and it received approval from the US Food and Drug Administration in 2018. Today it can include LASIK surgery – under the guidance of a system iDesign refraction studio – more than 1200 measurements for individual vision correction that is also fast and safe.

Christian Santana, now an electrical engineer at Johnson & Johnson Vision, has worked with the technology from the beginning, having originally helped develop the system to measure the mirrors of the James Webb Space Telescope while working in the early 2000s worked for Wavefront Sciences. .

“NASA was a very good partner,” Santana recalls, noting that work on the telescope helped the company improve algorithms in a seemingly irrelevant eye mapping system.

“Ultimately, the investments NASA made helped the company develop the technology to be useful for other applications, including LASIK eye surgery,” says Feinberg.
