Models for 8-, 16-, and 32-slit radial keratotomies with both different-sized clear central areas and different incisional scar widths have been produced. Five normal subjects who looked through a series of these models have had their glare sensitivity determined using variable contrast threshold targets surrounded by a constant glare source. Results show that increased glare sensitivity is present with small (less than 3 mm), clear central areas and wide (greater than or equal to 0.3 mm) incisional scars. The study suggests that finer scars, larger clear central areas, and configurations of eight and 16 slits should produce the least increase in glare sensitivity. These suggestions seem to be supported by studies performed on patients who have undergone radial keratotomy.
已经制作出了用于8切口、16切口和32切口放射状角膜切开术的模型，这些模型具有不同大小的透明中央区和不同的切口瘢痕宽度。五名正常受试者通过一系列这些模型进行观察，使用被恒定眩光光源环绕的可变对比度阈值目标来测定他们的眩光敏感度。结果表明，当透明中央区较小（小于3毫米）且切口瘢痕较宽（大于或等于0.3毫米）时，眩光敏感度会增加。该研究表明，更精细的瘢痕、更大的透明中央区以及8切口和16切口的构型应会使眩光敏感度增加最少。这些建议似乎得到了对接受放射状角膜切开术患者所进行研究的支持。
