Impact of multifocal contact lens wear on optical coherence tomography measurements of the cornea and retina

MFCL wear was associated with reduced OCT image quality in posterior segment imaging and with thinner RNFL measurements, while anterior segment quality and GCIPL parameters remained stable. Correlation analyses revealed that refractive status and lens spherical power subtly influenced GCIPL thickness. Therefore, OCT examinations in presbyopic patients should be interpreted with caution, and baseline scans without lens wear may be preferable, particularly in glaucoma screening.
