Multifocal contact lenses found to closely match corneal shape in study

Multifocal contact lenses generally conform well to the natural shape of the cornea, both centrally and peripherally, supporting their effectiveness in providing near vision correction for presbyopia, according to a study.

Researchers used custom-built spectral anterior segment optical coherence tomography (OCT) to analyze the fit of 1-Day Acuvue Moist Multifocal lenses on one eye of each of 13 participants.

The study assessed how closely the lenses’ shape matched the cornea by comparing curvature measurements on both the lens and the natural cornea across central and peripheral zones. Results showed a strong correlation (r > 0.79, P < 0.05) between the lens and corneal curvature, indicating good conformity.

Power profiles obtained through ray tracing showed that the actual lens additions were slightly lower than manufacturer-stated values but were consistent with previous off-eye measurements.
