Impact of contact lens correction on wavefront aberrations and vision quality in keratoconus
Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1811-1828, November 2025.Abstract Purpose To review the optical principles of contact lens correction in keratoconus, with a focus on residual ocular wavefront error and its impact on vision performance. Findings Corneal rigid gas permeable (RGP) contact lenses, commonly used in keratoconus management, often fail to improve vision quality to levels observed in non‐diseased ...

Incoherent Digital Holography Empowered by Wavefront and Information Engineering: A Review
Advanced Photonics Research, Volume 6, Issue 10, October 2025.Advancements in incoherent digital holography (IDH) have been achieved via wavefront engineering (using spatial light modulators, diffractive optics, and metasurfaces) and information engineering (using compressive sensing and deep learning). This paper presents an overview of IDH with wavefront and information engineering, paving the way toward its ...

Zernike phase spatial filter for measuring the aberrations of the optical structures of the eye
Journal of Biomedical Photonics & Engineering, 2015 To measure directly the wavefront aberration coefficients, we propose to use the multi-order diffractive element fitted with the set of Zernike polynomials. Polynomials of lowest degree describe defocusing (ametropy) and astigmatism.
