The KAMRA® Corneal Inlay Brings Life Back into Focus

Irvine, CA, March 8, 2017 — Pin­hole pho­tog­ra­phy has fas­ci­nat­ed us for cen­turies, from
ancient Greek philoso­phers exper­i­ment­ing with the pin­hole effect to today’s advanced
smart­phones uti­liz­ing small aper­ture tech­nol­o­gy to cap­ture a clear image instant­ly. Now
this sci­en­tif­ic prin­ci­ple, and foun­da­tion of pho­tog­ra­phy, is dra­mat­i­cal­ly chang­ing the way
we see as we get old­er and reduc­ing the need for dread­ed read­ing glass­es. The KAMRA
corneal inlay, devel­oped by Acu­Fo­cus, Inc., is a first-of-its-kind corneal inlay that brings
life back into clear focus using the same prin­ci­ples of the pin­hole effect for peo­ple with
pres­by­opia, a nat­ur­al loss of near vision that hap­pens to all of us start­ing in our mid 40s.

An esti­mat­ed 114 mil­lion peo­ple in the Unit­ed States have pres­by­opia. Some of the
signs and symp­toms of pres­by­opia are stretch­ing your arms out to see or read clear­ly
and blur­ry near vision that often leads to a con­stant shuf­fle of tak­ing read­ing glass­es on
and off. With pres­by­opia, the nat­ur­al lens of the eye that flex­es and focus­es light
allow­ing peo­ple to see near, becomes stiff over time. Even­tu­al­ly, the lens becomes
inflex­i­ble and as a result see­ing words and objects up close is increas­ing­ly dif­fi­cult.

Using the pin­hole effect, the KAMRA inlay focus­es rays of light enter­ing the eye to
regain a con­tin­u­ous and unin­ter­rupt­ed range of vision from near to far. Small­er and
thin­ner than a con­tact lens, the KAMRA inlay is a mini-ring with a tiny open­ing in the
cen­ter cre­at­ing a pin­hole effect. The inlay is sur­gi­cal­ly placed in only one eye by an
oph­thal­mol­o­gist to restore every­day vision allow­ing patients to clear­ly see text
mes­sages, read mag­a­zines or view a com­put­er screen. Designed with the goal of
reduc­ing depen­dence on read­ing glass­es for peo­ple 45 or old­er, the inlay has become
espe­cial­ly pop­u­lar with those who lead active lifestyles and want to func­tion at all
dis­tances with­out the need to lug around glass­es.

Because the KAMRA inlay uses the pin­hole effect, the range of vision is main­tained
over time. As you cel­e­brate more birth­days, you are still main­tain­ing clear vision from
near to far. It is tru­ly more of a life­long pres­by­opic solu­tion rather than the tem­po­rary
solu­tions pre­vi­ous­ly avail­able,” said Dr. William Wiley, a nation­al­ly-renowned
oph­thal­mol­o­gist and med­ical direc­tor at Clear Choice, the Cleve­land Eye Clin­ic and
Tole­do LASIK Cen­ter. “As an oph­thalmic sur­geon, it was amaz­ing see­ing the excite­ment
and delight those first patients had with their restored vision when they came back the
first week. Since then we’ve done hun­dreds of KAMRA inlay pro­ce­dures.”

The pin­hole effect is dif­fer­ent from oth­er solu­tions for pres­by­opia. For years, mono­vi­sion
tech­nol­o­gy has been used in con­tact lens­es and refrac­tive vision cor­rec­tion. Mono­vi­sion
LASIK cor­rects one eye for near vision while the oth­er eye remains focused on far
vision. For most, this tem­po­rary solu­tion means the loss of far vision and strug­gles with
dimin­ished depth per­cep­tion and binoc­u­lar visu­al func­tion.

Mono­vi­sion is basi­cal­ly a sta­t­ic solu­tion for a dynam­ic prob­lem,” Dr. Wiley said.
“How­ev­er with the KAMRA inlay, you’re basi­cal­ly treat­ing a dynam­ic prob­lem with a
dynam­ic solu­tion. We’ve nev­er had so many staff mem­bers jump on to one pro­ce­dure. I
think it’s sort of a tes­ta­ment, a great endorse­ment for the prod­uct to see the staff ral­ly
around it. We call them our KAMRA crew.”

Pres­by­opic patients also have relied on read­ing glass­es, which only use one-way
mag­ni­fi­ca­tion, so the per­son must con­stant­ly remove their glass­es to see things at a
dis­tance. Bifo­cals or pro­gres­sive glass­es cor­rect for near and far vision, but like read­ing
glass­es, leave the patient tilt­ing and cran­ing their head to hit that sweet spot, basi­cal­ly
the sin­gle point of clear focus that pro­vides clar­i­ty, so they can final­ly read the screen,
book or menu.

The KAMRA inlay is a bril­liant solu­tion that moves beyond the com­pro­mis­es that are
avail­able today for pres­by­opes,” said Al Water­house, Pres­i­dent and COO of Acu­Fo­cus.
“Instead of a sin­gle clear focal point obtained with read­ing glass­es and tra­di­tion­al
mono­vi­sion, pin­hole tech­nol­o­gy stretch­es that focal point over a long range for seam­less
near to far vision. Oth­er vision cor­rec­tion tech­nolo­gies rely on using increased lens
pow­er to influ­ence near vision and com­pro­mis­es good far vision. The KAMRA inlay
restores near vision while main­tain­ing far vision.”
