We present an observational sign that ensures perfect alignment during femtosecond laser-assisted in situ keratomileusis (FS LASIK). Alignment is assured when a microsponge is used to dry the flap and the area of dryness exceeds the area of direct touch of the microsponge. The area might even reach the whole circumference of the flap at the first touch. This sign of alignment can be explained by microcapillary action. This sign was not elicited in flaps created by a microkeratome.
我们提出一种观察迹象，该迹象可确保在飞秒激光原位角膜磨镶术（FS LASIK）期间实现完美对齐。当使用微海绵干燥角膜瓣且干燥区域超过微海绵直接接触的区域时，对齐得以保证。在首次接触时，该区域甚至可能达到角膜瓣的整个圆周。这种对齐迹象可以用微毛细管作用来解释。在使用微型角膜刀制作的角膜瓣中未出现这种迹象。
