Kansal V, et al. - Whether differences between eyes in axial length (AL) and corneal power (K) on optical biometry could predict refractive outcomes, was investigated. Findings demonstrated an association of interocular axial length difference of as little as ≥0.2 mm with a higher chance of >0.5 D of refractive error from target and worse uncorrected visual acuity (UCVA). Furthermore, data revealed no association of interocular K difference with worse refractive error from target, although a difference of ≥0.4 D was found to be associated with worse UCVA. Considering these cutoffs in preoperative planning and discussion with patients was recommended.
