Brief
Description:
A system to improve vision care accommodation and
intraocular lens development.
Applications:
This invention identifies the two limitations
associated with the traditional telecentric scan that most of the commercial
anterior segment optical coherence tomography (OCT) systems use and proposes a
novel design to tackle these issues.
Advantages:
Most of the commercial anterior segment OCT systems
use telecentric scan geometry in which the beam is shone straight into the eye
parallel to the optical axis. This technique poses two major challenges: first,
the design leads to a significant reduction in the amount of backscattered light
collected by the OCT system; and second, the fact that pupil dilation is
necessary to image a large diameter lens. The plan to overcome these limitations
is to design an asymmetric focusing optics system that provides angle of
incidence of each scan beam normal to the ocular surfaces. The final design
proposes a system which results in a substantial increase in light intensity
reflected from each surface. This technology will be applied to and improve
vision care accommodation, presbyopia, and intraocular lens
development.
