Abstract
Purpose: :
To evaluate stereopsis in patients implanted monocularly with the KAMRA small aperture corneal inlay.
Methods: :
Prospective, 6 month study of 60 patients using the Optec Functional visual analyzer Stereo test. Inclusion criteria included age of 45 - 60 years with a spherical equivalent between + 0.50 to -0.75 D and an uncorrected near visual acuity of worse than 20/40, and better than 20/100 and a best corrected distance VA ≥ 20/20 in both eyes.
Results: :
Mean patient age was 53 ± 3.7. There was no significant change in stereopsis, with a pre-op measurement of 36.1 ± 31.3 arc seconds and a post-op value of 35.5 ± 34.7 arc seconds. Contrast sensitivity remained within normal limits.
Conclusions: :
The KAMRA small aperture corneal inlay did not affect stereopsis and contrast sensitivity remained within normal limits.
