A review of angle kappa and multifocal intraocular lenses and their effect on visual outcomes
Acta Ophthalmologica, EarlyView.Abstract Although most patients are satisfied with their vision after multifocal intraocular lens (IOL) implantation, dissatisfaction has been reported for various reasons, including poor visual outcomes and visual disturbances. Many published reports hypothesise that preoperative angle kappa may be an associated factor in patient dissatisfaction ...

Adaptive particle image velocimetry based on sharpness metrics
Journal of the European Optical Society-Rapid Publications, 2018 Background Optical distortions can significantly deteriorate the measurement accuracy in particle image velocimetry systems. Such distortions can occur at fluctuating phase boundaries during flow measurement and result from the accompanied refractive ...

Sensing and control of segmented mirrors with a pyramid wavefront sensor in the presence of spiders
, 2017 The segmentation of the telescope pupil (by spiders & the segmented M4) create areas of phase isolated by the width of the spiders on the wavefront sensor (WFS), breaking the spatial continuity of the wavefront.

Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing
Acta Ophthalmologica, EarlyView.Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.

Revisiting PSF models: Unifying framework and high‐performance implementation
Journal of Microscopy, EarlyView.Abstract Localisation microscopy often relies on detailed models of point‐spread functions. For applications such as deconvolution or PSF engineering, accurate models for light propagation in imaging systems with a high numerical aperture are required. Different models have been proposed based on 2D Fourier transforms or 1D Bessel integrals.

Recovering pyramid WS gain in non-common path aberration correction mode via deformable lens
, 2017 It is by now well known that pyramid based wavefront sensors, once in closed loop, have the capability to improve more and more the gain as the reference natural star image size is getting smaller on the pyramid pin. Especially in extreme adaptive optics
