“…The pig eye has been used in neuroretinal studies due to the similarity of the distribution of the retinal layers to that of the human retina [1], and it is also a validated animal model of glaucoma [4]. Moreover, it has been used in cataract surgery research [5], in corneal transplant studies [6,7], and as a model in aberrometry studies [2,3].…”

“…Acosta and co-workers [28][29][30], for example, proposed a point diffraction interferometer to measure local prescriptions of PALs. Spiers and Hull [31] designed four types of binary filters used in an optical Fourier filtering setup, which were evaluated when taking quantitative measurements and when qualitatively mapping the power variation of PALs.…”

Refractive parameters are the main design and evaluation parameters of freeform spectacle lenses. In this paper, the mathematical model of refractive parameters is established, and the refractive power distribution on the whole surface is drawn with a radial basis function. The measurement methods are analyzed, and typical freeform spectacle lenses are measured with a freeform verifier. The refractive power distribution on the whole surface, the cylinder view, and the refractive power curve along the progressive corridor are drawn up. There are no evident image changes on the whole surface. The refractive power smoothly varies along the progressive corridor. In comparing the results with the analysis, measurement results are in agreement with the calculation.

“…Figure 9 shows wavefronts obtained in two samples of pig lenses. 76 Again, most of these in vitro studies correspond to non-human lenses; published in vivo measurements are always indirect; [77][78][79] so that there is a large uncertainty on the contribution of the lens to the optical quality of the eye. There are too many unknowns to measure and model the crystalline lens.…”

Cornea, lens and eye models are analyzed and compared to experimental findings to assess properties and eventually unveil optical design principles involved in the structure and function of the optical system of the eye. Models and data often show good match but also some paradoxes. The optical design seems to correspond to a wide angle lens. Compared to conventional optical systems, the eye presents a poor optical quality on axis, but a relatively good quality off-axis, thus yielding higher homogeneity for a wide visual field. This seems the result of an intriguing combination of the symmetry design principle with a total lack of rotational symmetry, decentrations and misalignments of the optical surfaces (J Optom 2009;2:3-18 ©2009 Spanish Council of Optometry) KEY WORDS: human eye's optical design; eye models; design principles; ocular aberrations; optical quality of the eye. RESUMENEn este trabajo, los modelos de córnea, de cristalino y de ojo se analizan y se comparan con los datos experimentales para evaluar las propiedades y, eventualmente, para desvelar los principios del diseño óptico que afectan a la estructura y al funcionamiento del sistema óptico del ojo humano. A menudo encontramos una coincidencia razonable entre los modelos y los datos experimentales, pero también se ponen de manifiesto algunas paradojas. El diseño óptico parece corresponderse con el de un gran angular. En comparación con los sistemas ópticos convencionales, el ojo tiene una mala calidad óptica en eje pero, por el contrario, presenta una calidad relativamente buena fuera de eje, proporcionando así una gran homogeneidad a una amplia extensión del campo visual. Este hecho parece ser el resultado de una curiosa combinación del principio de diseño simétrico con una total ausencia de simetría de rotación, con descentramientos y con una deficiente alineación de las superficies ópticas.

Analysis of the optical properties of crystalline lenses by point‐diffraction interferometry

Abstract: Modified point-diffraction interferometry is a wavefront-sensing technique that can be used to accurately analyze phase aberrations in eye lenses and hence evaluate their contribution, in terms of significant aberrations, to the total aberrations of the eye.
