Abstract
Aims The aim of this retrospective study was to identify factors affecting myopic shift from predicted values of refraction after sulcus fixation of foldable acrylic intraocular lenses (IOLs). Methods A total of 91 eyes from 91 consecutive patients, each of whom underwent primary implantation of sulcus-fixated foldable acrylic IOLs, were assessed. AcrySof MA60BM and Sensar AR40e multi-piece IOLs, and AcrySof SA60AT and BioVue single-piece IOLs were implanted. The type of IOL and axial length (AL) were analysed to identify differences in the spherical equivalent between the predicted refraction values obtained using the SRK/T formula and the manifested refraction values. Results The mean myopic shift from the predicted refraction calculated using the SRK/T formula was −1.04 dioptres (D) ±0.85 SD with sulcus fixation of the foldable acrylic IOLs. The type of IOL (multi-piece vs single-piece) did not affect the degree of myopic shift (p=0.100, independent t-test). However, as the AL increased, the myopic shift decreased (p=0.033, r=0.223, Pearson's correlation). Conclusion The myopic shift from the predicted refraction differed following sulcus fixation of foldable acrylic IOLs based on the AL, and therefore surgeons should take the AL into account when they determine the IOL power for sulcus fixation procedures.
