Possible Risk Factors and Clinical Effects of Opaque Bubble Layer in Small Incision Lenticule Extraction (SMILE)

Abstract

Eyes with a thicker cornea or a thinner lenticule are more likely to develop OBL during SMILE. The OBL does not affect the overall clinical outcome. In eyes with extensive OBL, there is a higher incidence of flap tear and a lower predictability value. [J Refract Surg. 2017;33(1):24-29.].
