Light-field exam:
Chip Berestka, MD
The slit lamp exam hasn't changed in 75 years,
Dr. Berestka said, introducing the light-field
exam. Light-field optics is a new branch of
photography that can image a 3D cube of space
permitting after-the-fact focusing. He said it
would have selective focus, all-in focus, and
perspective-changing 3D. To recreate the slip
lamp exam after the fact, a technician would
capture light-field images as a slit traverses the
eye in the X axis to create a library of images.
The doctor could then later "drive through" the
slit lamp exam in his or her own sequence on
a computer or smartphone. How would this
change ophthalmology? Dr. Berestka said the
slit lamp could be acquired by the technician.
The doctor could then review the exam with
the patient, pointing out pathology at the same
time. There's no wasted time at the slight lamp,
he said, and it will also integrate into the EMR
system. This technology, he said, is ideal for
postop and brief visits, and it frees up time for
surgery. The system would help make telemedi-
cine possible for ophthalmology.
Dr. Berestka added that the market for this
product is large. He expects prototype develop-
ment in a year and full production in 2 years.
He asked for $5 million and was also seeking
talent for the board of directors and medical
advisory board.
