BCVA: best-corrected visual acuity. The best-corrected visual acuity was measured and calculated with the EDTRS visual acuity chart and represented with logMAR. Snellen equivalent is shown in the text. Bilateral nuclear cataract in family B has more opacity in the lens nucleus, while bilateral nuclear cataract in family A has less opacity. IOL: intraocular lens. NA: not acquired. NO: not found; R: right; L: left.
