IOL selection
diopters
SECONDARY, IOL

IOL styles: the style of IOL used for capsular bag implantation is single-piece hydrophobic spheric monofocal IOL (SA60AT, Alcon Laboratories, America), and the style of IOL used for sulcus implantation is three-piece hydrophobic spheric monofocal IOL (AR40e, Sensar, America).IOL power: targeted postoperative refraction range from + 4 diopters to emmetropia will be recommended according to age at secondary IOL implantation and/or the ocular refraction of the contralateral eye.IOL power adjustment for sulcus implantation: When the predicted power is between 11.5 and 30D, a corresponding reduction of 0.50–2.50D is made for a ciliary sulcus implanted IOL according to the unpublished refractive data from our cohort.
