The Ophthalmic Chairs and Stands are the essential foundation of all ophthalmic refracting lanes. They come in a tremendous variety of styles and complexities.
Ophthalmic Refracting Chairs differ greatly in appearance but all perform the same basic function.They have a hydraulic or electric base to raise and lower the patient, and most offer a tilt function or full recline mode to lower and recline the patient.
Ophthalmic Chairs and Stands Features
Ophthalmic Refracting Ophthalmic Chairs and Stands are comprised of several different assemblies. The overhead lamp offers illumination for reading cards. The Phoropter arm is mounted on a pole and in most cases is counterbalanced to offer ease of movement. The Slit Lamp Arm is generally integrated into the base of the stand to support the greater weight of many Slit Lamps. Many stands also offer a 3rd arm for the Keratometer, which is also mounted on the pole. It is essential that this arm be positioned correctly, to avoid damaging the other instruments.
In addition to the arms, most stands have charging wells for hand held instruments and a binding post or outlet for the Binocular Indirect Ophthalmoscope. They may also include switches to control the room lights and projector.
Many manufacturers also offer a complete refracting desk which includes the basic functions listed above as well as a Trial Lens drawer and controls for other room and chair features. Another system offers a rotating desk which brings the basic instruments as well as high tech instruments to the patient.
