Methods: Patients implanted with the monofocal ZCB00 intraocular lens (Johnson and Johnson) were examined with the KR-1W Wavefront Analyzer (Topcon) without pharmacological mydriasis and with it afterward. Optical aberrations were analyzed considering a 4-mm pupil and a 6-mm pupil for both examinations. Results: Sixty-six eyes of 33 patients with a mean axial length of 23.35 ± 0.91 mm were assessed. The mean pupil diameter at the baseline examination was 5.05 ± 0.88 mm and under pharmacological mydriasis, it was 6.29 ± 0.84 mm. Outcomes were similar with and without dilation in the 4-mm comparison. However, there was a great disparity in the 6-mm comparison. Most of the values obtained under mydriasis were statistically lower than at baseline (P < 0.05). Conclusion: The iris interferes with measurements of wavefront aberrations, and therefore, real pupil size should always be checked before evaluating optical aberrations with Hartman–Shack sensors. When pupil size is smaller than the analyzed diameter, ocular, and internal, and sometimes, corneal aberrations are estimated far more positive than real values. 000145095 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-sa$$uhttp://creativecommons.org/licenses/by-nc-sa/3.0/es/ 000145095 592__ $$a0.408$$b2024 000145095 593__ $$aOphthalmology$$c2024$$dQ3 000145095 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000145095 700__ $$aGiménez, Galadriel 000145095 700__ $$0(orcid)0000-0001-6072-1545$$aMéndez-Martínez, Silvia 000145095 700__ $$0(orcid)0000-0002-6745-7668$$aLarrosa, José M.$$uUniversidad de Zaragoza 000145095 700__ $$0(orcid)0000-0002-1402-3129$$aPolo, Vicente$$uUniversidad de Zaragoza 000145095 700__ $$0(orcid)0000-0003-2389-8282$$aPablo, Luis$$uUniversidad de Zaragoza 000145095 7102_ $$11013$$2646$$aUniversidad de Zaragoza$$bDpto.
