• In strabismus surgery, the characteristics of the needle will affect the length and depth of the scleral bite. In comparing the needle curve, it was found that the acute curve will produce a significantly shorter bite but of equal depth when compared with the needle with a shallow curve. In comparing the effect of the point of the needle, it was found that the needle with the point at the bottom of the needle will produce a bite of equal length but significantly deeper when compared with a needle with the point at the top.
