Project Details


Increasing numbers of corneal transplants for visual rehabilitation are
being performed in the United States. The adequacy of visual function in
these patients has been assessed only in terms of visual acuity, yet the
importance of non-acuity parameters in real-world visual function is
increasingly apparent. The specific aim of this proposal is to establish
the effect of corneal transplantation on contrast sensitivity function and
to determine the role of contrast sensitivity in the visual performance of
transplant patients. The proposed method includes the use of an automated
testing system of computer generated spatial frequencies as well as a
non-automated chart system of measurement of contrast sensitivity. These
tests will be applied to a controlled population of conreal transplant
patients with good Snellen acuities. The pilot data gathered from this
study, if positive, will serve as the basis for extending these
investigations beyond the scope of this study to an assessment of
real-world visual function in a variety of corneal diseases as well as in
the burgeoning repertoire of surgical alterations of the anterior segment.
