ｍｉｎｉ－ＲＫ是指局限于从角膜中央３ｍｍ视区向外延伸３．５ｍｍ的放射状切开方法，将之与延长至角膜缘或角膜缘外的＂常规＂ＲＫ比较，以确定在钝性外伤后，较短的角膜切口发生破裂的可能性。取１６只新鲜眼球剪下带５ｍｍ巩膜环的角膜组织，平均分为四组与人工前房连接，一组做常规４切口ＲＫ，一组不做切口作为对照组，另为两组分别做４切口和８切口ｍｉｎｉ－ＲＫ，用泵将平衡盐液（ＢＳＳ）缓缓注入人工前房，用电子压力转换仪监测压力变比。结果发现，对照组在角膜缘处破裂手术组均在切口处破裂，导致接受ｍｉｎｉ－ＲＫ的角膜破裂压力较常规ＲＫ角膜破裂压力要高的多，二者有显著性差异（Ｐ＜０．０１）。因此认为，ｍｉｎｉ－ＲＫ对眼部可能发生外伤的高危病人非常有益。
The mini-RK refers to a radial incision method that is limited to a 3.5 mm extension outward from a 3 mm central corneal viewing area and compared to a “conventional” RK that extends to the limbus or limbus to determine whether the blunt trauma , Shorter corneal incision rupture possibility. Corneal tissue with 5mm scleral rings was cut out with 16 fresh eyeballs and divided into four groups and artificial anterior chamber. One group did routine 4 incision RK, one group did not incision as the control group, and the other two groups did 4 Incision and 8-incision mini-RK, the balanced salt solution (BSS) was slowly injected into the artificial anterior chamber with a pump and the pressure ratio was monitored using an electronic pressure transducer. The results showed that the control group ruptured at the limbal rupture at the incision, which resulted in a much higher corneal rupture pressure than mini-RK ). Therefore, mini-RK is very beneficial to patients at high risk of ocular trauma.
