Stereoacuity after small aperture corneal inlay implantation.
OBJECTIVE
The aim of this study was to compare stereoacuity before and after KAMRA corneal inlay implantation for the correction of presbyopia.


METHODS
This is a prospective study of 60 patients who underwent KAMRA inlay implantation. Patients were examined before and 6 months after surgery for stereoacuity, uncorrected distance visual acuity (UDVA), and uncorrected near visual acuity (UNVA).


RESULTS
The mean stereoacuity before surgery was 29.5±28.1 arcsec (range: 20-200) and at 6 months was 29.8±26.4 arcsec (range: 20-200). The decline in stereoacuity was not statistically significant. At 6 months follow-up, UDVA was 20/25 or better in all 60 patients and UNVA was J2 (20/25) or better in 51 (85%) patients.


CONCLUSIONS
There is no significant change in stereoacuity following KAMRA inlay implantation. The KAMRA inlay is a good treatment option for improving near vision in presbyopic patients while preserving stereoacuity and distance vision.
