Ophthalmic apparatus

An ophthalmic apparatus comprising:

• an intraocular pressure measurement part including a blowing unit which blows a fluid to a cornea via a nozzle which is movable to a retreat position and to a measurement position for measuring intraocular pressure of an eye of an examinee;
• an eye characteristic measurement part in which a measurement optical system, which photo-receives reflection light from the eye for measuring an eye characteristic of the eye, is arranged;
• a main body in which the intraocular pressure measurement part and the eye characteristic measurement part are arranged;
• a first moving unit which moves the main body with respect to the eye in a working distance direction;
• a second moving unit which moves the intraocular pressure measurement part with respect to the main body in the working distance direction;
• mode switching means for emitting a switching signal to switch between a first mode for measuring the eye characteristic and a second mode for measuring the intraocular pressure;
• and
• a movement control unit which controls driving of the first moving unit so as to locate the main body once at a rear position in a direction away from the eye, and then controls driving of the second moving unit so as to move at least a nozzle of the intraocular pressure measurement part from the retreat position to the measurement position so that the nozzle gets near to the eye by a predetermined distance with respect to the main body based on the switching signal from the first mode to the second mode.

• an intraocular pressure measurement part including a blowing unit which blows a fluid to a cornea via a nozzle which is movable to a retreat position and to a measurement position for measuring intraocular pressure of the eye, which has a working distance shorter than a working distance which is necessary for measurement by the eye characteristic measurement part;
• a main body in which the eye characteristic measurement part and the intraocular pressure measurement part are arranged;
• a first moving unit which moves the main body with respect to the eye in a working distance direction;
• a second moving unit which moves the intraocular pressure measurement part with respect to the main body in the working distance direction;
