Abstract
Apparatus and methods are described including illumination equipment (300) configured to direct light into an eye of a subject. An optical device (100) is placed inside the subjects eye, the optical device including a Fabry Perot interferometer (106) comprising at least two mirrors (162, 164), the Fabry Perot interferometer (106) being configured such that a distance between the mirrors (162, 164) varies as an intraocular parameter of the subjects eye varies. A retroreflector (140) is configured such that light that is transmitted through the Fabry Perot interferometer (106) is automatically reflected out of the subjects eye. Readout equipment (400) is configured to detect the light that is reflected out of the subjects eye. Other applications are also described.
