After years of advanced training in
0:03
Russia, Germany, and Japan, where she
0:06
had opportunities to learn from leading
0:08
specialists in opthalmology,
0:11
Dr. Hang has obtained 10 patents for
0:14
corneal transplantation techniques that
0:17
have been recognized internationally. In
0:19
2025, Dr. Dr. Wang and Professor
0:23
Kalanikov Yuri, a leading opthalmology
0:25
specialist from Russia, published the
0:28
results of their collaborative research
0:30
on the Colony of Deng technique for
0:33
posterior endothelial keratlasty or PDK.
0:40
The device that Dr. Hang an and I
0:42
developed is an optimized solution for
0:45
preparing graph tissue for PDK coral
0:48
transplantation. Modern medicine has
0:50
shown that transplanting the entire
0:52
cornea is no longer appropriate in many
0:55
cases. Instead, only the damaged layer
0:57
of tissue needs to be replaced. This
1:00
approach significantly reduces the risk
1:02
of graft rejection, increases tissue
1:05
adhesion, and in many cases can almost
1:07
completely eliminate the possibility of
1:09
incompatibility.
1:11
Based on this principle, we developed a
1:13
device that enables the precise
1:15
separation of the endothelial layer of
1:17
the cornea, ensuring safety and an
1:20
optimal graph size.
1:23
The invention comprises a device for
1:26
separating and preserving corneal
1:28
tissue. Featuring an improved mechanism,
1:31
it increases the success rate of corial
1:34
layer separation to more than 95%.
1:37
Significantly higher than the
1:38
approximately 36.6 6% achieved with
1:42
previous techniques.
1:45
The device helps reduce the risk of
1:47
endothelial cell damage, [music]
1:49
minimize graft failure, and optimize the
1:51
use of donated corneas, which remain in
1:54
critically short supply.
1:57
What began as an idea in 2019 took
2:00
nearly seven years of persistent testing
2:03
and refinement before the two doctors
2:05
completed the invention and put it into
2:08
practical [music] use, offering patients
2:10
safer treatment options.
2:17
>> I feel it's a very rewarding process
2:20
because everything we do it's for the
2:23
aim to improve patients life. We are
2:27
very happy not just as doctors [music]
2:28
but also as scientists who continue
2:32
non-stop at improving and getting better
2:34
[music] at our craft.
