Abstract:
PURPOSE: To evaluate the change of ocular aberration after LASIK using Zernike's polynomial expansions. METHODS: Sixty eyes of thirty consecutive patients that underwent LASIK were examined prospectively. The ocular aberration was measured with Hartman-Shack aberrometer (WASCA Wavefront Analyzer, USA) at postoperative 30, 90, and 180 days. The postoperative values were compared with that of preoperation. RESULTS: The average age is 27.6 years old. The range of preoperative refractory error were from -3.00 Diopter (D) to -11.00 D. The increase of spherical and triangular coma aberrations (4.7- fold and 3.5- fold, respectively), with respect to preoperative values. There were statistically significant differences between preoperative and postoperative high order RMS at the postoperative 180 days (p<0.05). CONCLUSIONS: The postoperative increases of RMS in higher order aberration, coma aberration, triangular aberration was observed.
