分别用Slataper视标法和模式视诱发电位(P-VEP)法,测定18只人工晶体植入眼的调节力,结果分别为:2.20±0.60D和5.27±1.28D。P-VEP法的测量结果,比Slataper视标法高3.07±0.96D,但两种测定结果间有显著相关性(r=0.71,P<0.01)。因此,用P-VEP测量人眼调节是一种新的、值得尝试的客观方法,尤其适用于反应迟钝,判断力差的小孩和高龄老人。同时,研究结果表明人工晶体眼确实表现有一定的调节力。
Slataper astigmatism and mode-induced evoked potentials (P-VEP) were used to measure the accommodative power of 18 eyes implanted in the eye, respectively. The results were 2.20 ± 0.60D and 5.27 ± 1.28D, respectively. The measurement of P-VEP method was 3.07 ± 0.96D higher than Slataper’s standard method, but there was a significant correlation between the two methods (r = 0.71, P <0.01). Therefore, measuring the human eye with P-VEP is a new and objective method worth trying out, especially for children and the elderly with poor response and poor judgment. At the same time, the results show that the actual performance of artificial lens has a certain regulatory power.
