| Popis: | PURPOSE: To compare ocular wavefront aberrations of normal and dry eyes and to describe the characteristics of higher order aberration in dry eyes. METHODS: Wavefront analysis of higher order ocular aberrations (total S^sub 3+4+5^, spherical-like S 4 , coma-like S^sub 3+5^) was performed with a HartmannShack aberrometer in 20 dry eyes and 20 normal control eyes. RESULTS: Total, spherical-like, and coma-like aberrations were significantly greater in dry eyes than in normal controls (P4 : factor of 2.50; coma S 3 : factor of 2.70) and 6-mm-diameter pupil (S^sub 3+4+5^: factor of 2.29, S 4 : x2.53, and S^sub 3+5^: factor of 2.40). CONCLUSIONS: Eyes of dry eye patients showed greater optical aberrations compared with normal control eyes. Increase in higher order aberrations in dry eyes resulted from increased tear film irregularity. [J Refract Surg 2004;20:243-247] |
