Table 1.

Summary of wavefront RMS (microns) at baseline and after extensive tear break-up for five eyes. RMS of wavefronts reconstructed by either modal (column 1) or zonal (column 2) methods are used to compute the RMS contributed by three different scales of aberration: LOA (Zernike order 2), HOA (Zernike orders 3-10), and VHOA (zonal – modal wavefront). See the Rationale section of Methods for descriptions of analysis methods and aberration scales. Also included (in parentheses) are the ratios and differences of RMS after TBU compared to the baseline data. Averages for all 5 eyes are in the bottom row.
