PURPOSE To investigate the effect of laser spot size on the outcome of aberration correction with scanning laser corneal ablation. SETTING Cleveland Clinic Foundation, Cleveland, Ohio, USA. METHODS Corrections of wavefront aberrations of Zernike modes from the second to eighth order were simulated. Gaussian and top-hat beams of 0.6 to 2.0 mm full-width-half-maximum diameters were modeled. The fractional correction and secondary aberration (distortion) were evaluated. RESULTS Using a… CONTINUE READING
