Pattern reversal VECPs show a dependence on visual acuity and therefore are suitable for objective determination of refraction, this method, however, was of limited clinical use for two reasons, as, on the one hand, the required impulse parameter was difficult to change using the traditional mechanically functioning pattern stimulator and, on the other hand, diagnosis war very timeconsuming. Using a pattern impulse picture presented on a monitor by an electornic impulse apparatus all impulse parameters can easily be changed and throught he introduction of a microprocessorsystem the evaluation can be observed on-line.
模式翻转视觉诱发电位显示出对视敏度的依赖性，因此适用于客观验光。然而，由于两个原因，这种方法在临床上的应用有限。一方面，使用传统的机械功能模式刺激器很难改变所需的脉冲参数；另一方面，诊断非常耗时。使用电子脉冲装置在监视器上呈现的模式脉冲图像，可以轻松改变所有脉冲参数，并且通过引入微处理器系统，可以在线观察评估结果。
