Into the future
There is no sign of slowdown in the pace of innovation, Dr. Crandall continued. Lasers continue to increase in performance and versatility. The latest development is a femtosecond laser that can reshape an IOL that has already been placed in the eye.
“Instead of doing a lens exchange, you can change the power of the existing lens by four D, plus or minus,” he said. “You can add or remove astigmatism. You can add or remove multifocal, all with the lens in the eye. And you can do it in 30 seconds.”
Innovation is also transforming low-tech procedures, he said—one of the latest developments being a handheld device (miLOOP, Iantech) that fragments any grade of cataract using a thin, super-elastic filament.
No laser, no phaco, and no external power source are needed, just a steady, surgical hand, he noted.
