To investigate induced ocular aberrations and optical image quality after lens extraction and implantation with monofocal and various types of multifocal intraocular lenses, using a pyramidal aberrometer at 3- and 4-mm pupil size.
Vissum Innovation, Alicante, Spain.
195 eyes, divided in 9 groups: A, 19 eyes with monofocal IOL (Acrysof SA60AT); B, 19 with EDOF (Miniwell); C, 24 with refractive IOL (Lentis Mplus LS-313 MF30); D, 33 with refractive IOL (Lentis Mplus LS-313 MF15); E, 17 with accommodative IOL (Akkolens Lumina); F, 31 with diffractive IOL (AT LISA tri 839MP); G, 20 with refractive IOL (Precizon Presbyopic, Ophtec); H, 20 with diffractive IOL (AcrySof IQ PanOptix) I, 11 with aspheric monofocal IOL (Eyehance). Point spread function (PSF), PSF excluding second order aberrations, wavefront error, high order aberrations, low order aberrations were analyzed using the Osiris pyramidal aberrometer.
There were no differences among the groups in terms of preoperative visual acuity, refractive error or IOL power used. Group F had the highest PSF not taking into account second order aberrations at both 3- and 4-mm pupil size (0.52±0.12; 0.31±0.07), followed by group H (0.42±0.09; 0.26±0.03), group A (0.39±0.1; 0.27±0.07), group I (0.39±0.09; 0.21±0.04) and group G (0.34±0.11; 0.24±0.12).
Aberrometric parameters included in this investigation showed significant differences among different lenses and IOL multifocal technologies. This method of analysis of retinal image quality offers a new opportunity to evaluate in vivo different optical technologies and allow us to make a better selection of the IOLs to be used for our patients.
