The protocols for studies of intraocular lens (IOL) formula accuracy recommend including only one eye from each study subject.[2] The selection criteria applied if one eye is chosen should be described clearly in the paper.[3] Our inclusion and exclusion criteria, which are the same as those of many studies, could include patients with diseases other than cataracts. As the refraction accuracy decreases with visual acuity,[2] we thought that eyes with better visual acuity after surgery were simply affected by the refractive error. This is certainly a little different from the protocol;[3] however, as written in the protocol, we clearly describe our selection criteria in the paper.
