BACKGROUND: Corneal hydration is an important factor in laser corneal ablation. In photorefractive keratectomy (PRK), corneal ablation rate and final ablation surface quality are strongly dependent on corneal hydration. We used, a spectroscopic techn

In sight correction technologies, it is of extreme importance to know what outcome of the planned operation could be. Conventionally, cornea shape is measured, or even refraction distribution in the eye, that are used for calculations of the to-be-ab

A modified double-pass wave model is proposed being a wave diffraction model of the secondary coherent field formed due to double pass of light in the human eye system. The modification takes into account: cornea contribution into total eye refractio

In photorefractive sight correction, pre-operational computations of to-be-ablated layers are usually based on information about cornea shape that is one of the causes of aberrations. To obtain high-quality results of operation, contributions to aber

There is a problem in photorefractive eye microsurgery of mapping the refraction distribution in the eye, caused by distortions of the cornea shape, lens aberrations, and non- homogeneities of the components of eye media. We investigated shearing int

To measure the shape of the cornea and its declinations from the necessary values before and after PRK operation, s well as the shape of other spherical objects like artificial pupil, a technique was used of double-frequency dual-beam interferometry.
