Zhu X, et al. - The consequence of preoperative biometry fixation stability on postoperative refractive errors was comprehensively investigated, in highly myopic cataractous eyes. The data depicted that an association between poor preoperative biometry fixation stability with long axial length (AL) and severe posterior subcapsular opacity was responsible for a substantial deviation of the refractive errors, after cataract surgery in highly myopic eyes.
