Introduction




A prosthetic eye replaces a real human
eye lost in an accident or by a disease
These eyes primarily serves esthetical
purposes
The appearance of prosthetic eyes
have improved quite dramatically over
the years
However more improvements need be
done
Current Prosthetic Eyes


Prosthetic eyes provide patients with a very
closely resembling replica of real human eye.
However, the main draw back of current
prosthetic eyes is lack of dynamicity in the
pupil.

Dyno I’s Proposed Solution



Dyno I® have developed a design in
which a dynamic pupil is integrated
into a prosthetic eye.
A custom made LCD consisting of
several rings is utilized as the pupil of
the eye.
The system is also consists of
photodiode and a microcontroller to
measure the intensity of the ambient
light.
Overall System Design
Custom-Made Transmissive
LCD
Final Hardware Design
Microcontroller




Ultra low-power microcontroller
featuring LCD driver
Ability to reduce unnecessary power
consumption
Utilizing the on board A/D converter to
measure the intensity of the ambient
light
Battery powered, low cost and reliable
Software Design





Compare photo diode generate voltage with
calibrated reference voltage
Calculating the number rings necessary to
be ON
Making the CPU to go the Sleep mode and
remain there for 1 second
Reducing power consumption
Going to standby mode when at pitch dark
for more than 5 min: tremendous power
saving feature
Software Algorithm
Design Obstacles



Battery powered: One 3V battery
preferentially lasting for 2 years
All the circuitry components including
the battery need to be heat resistance;
the prosthetic eyes need to be heat
cured
Size constraint: the smallest the
circuitry the more universal the product
will be

Projected Market




Approximately new 400 prosthetic
eyes made in BC last year
Life cycle of 2 to 3 years for existing
eyes: they need to be replaced
Approximately 40,000 prosthetic eyes
made in North America last year
Estimated 20,000 colored eye
Projected Market


Our target price: $125
Estimated revenue from North
America: $2,500,000
Projected Startup funding required:
$150,000
Possible sources of funding: IRAP,
Bank Loans, Angel Investor, etc.
Future Improvements



Thin LCD: possibly the newly
introduced thin film LCD
Designing our custom-made integrated
circuitry, IC: extremely small and low
powered consumption
Source of power: rechargeable
batteries, solar cells, etc.
Conclusion



Our product improves the appearance
of a prosthetic eyes by a great extent
Our designed prosthetic eye at Dyno I®
will provide patients with a very cost
effective and cosmetically appealing
solution that functions very similar to a
real eye
Sustainable market with potential to be
extended to European and other
markets throughout the world.
