Opis:
New objective methods to measure the optical aberrations of the eye are reviewed, in particular the probably more representative ones: Hartmann-Shack wavefront sensor and laser ray tracing. They are shown to be robust and provide highly reliable data, which are permitting to obtain many new results about the optics of the eye in basic and clinical studies. In addition, different experiments have demonstrated the correction of eye's aberration. Again two representative approaches are reviewed. The first results were obtained with the close-loop adaptive optics system developed at the University of Rochester. Later on, phase plates made by photosculpture in photoresist (placed in front of the eye like conventional lenses) have also permitted the correction of ocular aberrations. This is a new, but already very active field of research, which has open many new questions and a wide variety of applications.

Opis:
During the diagnostic research done by means of optical devices equipped with radiation sources from the near infrared range the phenomena indicating the perception possibility of this range by a human eye were observed. In this contribution the initial results of the research of this phenomenon were presented. Sources of radiation applied in laser polarimeters (785 nm) and devices designed for optical coherent tomography (820, 850 nm) were taken into particular consideration. Perception tests with the use of a laser diode generating at the wavelength of 940 nm were also carried out. It was stated that the radiation from the range examined can be recorded by a human eye giving a colour sensation - in practice independently of the wavelength of the radiation beam falling into a retina.

Opis:
This contribution presents an application of frequency-domain optical tomography to ophthalmology. Essential theoretical foundations of time-domain and frequency-domain optical tomography are presented. Images of sections through the anterior chamber, the corneo-scleral angle and fundus of the eye are reconstructed from the spectral fringes. The morphological information gained by tomograms is important for diagnosing and planning of a treatment of glaucoma.
