Abstract Details


Evaluate corneal ASTR and compare to attempted in consecutive cases of myopic Smile.

Setting: Clinical and Research Eye Institute, Athens, Greece


In 62 myopic Smile eyes (43 patients), anterior segment OCT 3D mapping of stroma and epithelium documented the STR at 3 months. ASTR was compared to the maximum PSTR and correlated with residual refractive error.


Mean ASTR was 81.91 �Â�± 19.79 �Â�µm, vs. the mean RSTR of 103.06 �Â�± 22.05 �Â�µm. The attempted versus achieved thickness outliers correlated with deviations of refractive correction from planned and appeared higher that our previous reported LASIK cases in myopias > 6 Diopters.


ASTR in Smile shows statistically under-corrections in higher myopic corrections attempted.
