摘要
目的:比较波前像差仪与主观验光法对屈光度检查的结果,探讨波前像差仪对低阶像差测量的可靠性和准确性。方法:对2007-07/2007-10在我院拟行准分子激光角膜屈光手术的患者88例168眼,分别使用以Hartmann-Shack原理为基础设计的德国蔡司WASCA波前像差仪分析系统以及主观插片验光方法进行检查,并对近视球镜、近视柱镜、散光轴向的结果比较、分析。结果:波前像差仪与主观验光测量的屈光度较为接近,等效球镜度分别为-6.53±1.64D和-6.44±1.89D;近视球镜度分别为-5.93±1.65D和-5.83±1.80D;近视柱镜度分别为-1.22±0.66D和-1.27±0.70D;散光轴向度分别为110.67±75.69°和119.24±74.21°;四组数据的统计学分析均无显著性差异(P>0.05)。结论:波前像差仪在无需散瞳的情况下能够较为准确地反映眼屈光度的情况。
AIM： To compare wavefront analyzer the dioptre results obtained by and subjective refraction test, respectively, and to evaluate the accuracy and reliability of lower-order aberrations measured by wavefront analyzer.
METHODS： A total of 88 myopia patients （168 eyes）, underwent excimer laser corneal refractive surgery in our hospital from July to October, 2007, were examined by Carl Zeiss wavefront analyzer （ based on Hartman-Shack principle） and subjective refraction, respectively. The results of spherical dioptric, cylindrical dioptric and axis of cylinder were compared and analyzed.
RESULTS. The results of diopter examined either by wavefront analyzer or subjective refraction showed a high similarity. Spherical equivalent were -6.53±1.64D and - 6. 44 ±1.89D; Spherical dioptre were -5.93±1.65D and - 5.83±1.80D; cylindrical Spherical were -1.22±0.66D and - 1.27±0.70D; axis of cylinder were 110.67±75.69° and 119. 24 ±74.21°, respectively. There were no statistically significant differences among those four groups （P 〉0. 05）.
CONCLUSION： The wavefront analyzer can provide an accurate and reliable dioptre results in the evaluation of the refractive situation without mydriasis.
