Red reflex-guided big-bubble DALK technique enhances control of dissection depth
A modified big-bubble technique guided by intraoperative red reflex may allow for better control of depth at which a cannula is inserted during deep anterior lamellar keratoplasty, according to a study.The big-bubble technique has been established to overcome the limitations associated with DALK, but it still has a challenging learning curve and poor standardization caused by the difficulty of inserting the cannula into the stroma. If insertion is too shallow, it can result in failure of the bubble formation and diffuse corneal emphysema, whereas too deep of an insertion can (Read more...)
