The slit lamp is a microscope with a light attached that allows the doctor to examine your eye under high magnification.

The refractometer determines electronically the refractive condition of the eye, as well as the corneal curvatures.

The tonometers are devices which assess the intraocular eye pressure.

The lensmeter is a measuring glasses system, including bifocal and multifocal lenses, as well as prisms. It also ascertains the optical lenses’ centers.

This simple screening test is used to assess the macula (the center of the retina).
