A Guide to Ophthalmic Instruments

by Wang M. Sales Executive

The ophthalmic instrument is the instruments that are needed by the ophthalmologist while performing eye tests and surgeries. Various kinds of devices are used by professional eye surgeons to diagnose and detect different kinds of eye diseases and infections.

The ophthalmic instrument tables is one of the most important things needed by the eye surgeon as it will hold all the necessary equipment that is needed for the check-up. This is why every eye specialist should look for a sturdy table that can hold a lot of weight.

There are many types of instrument tables that have a variety of assorted features. Some of the tables come in pairs with an ophthalmic chair with extra features like a height adjustment facility, safety stoppers, and sliding trays.

Some advanced tables also have an attached table light, trays for slit lamps and completely motorised controls. Since every eye specialist has some different needs, different ophthalmic units focus on several things.

There are many types of standard pieces of equipment that all ophthalmologists use. Some of them can be brought in parts and assembled later on. But it is better to get the complete ophthalmic refraction units so that there are no installation issues afterwards. Moreover, they have high costs so it is recommended to do a good background check before deciding on buying a complete refraction unit.

A refraction unit also consists of a handheld ophthalmoscope. It is a device used to examine the insides of an eye. It generally has an in-built power source and a focused light. There are also many adjustable lenses to focus on different parts of the eye. The ophthalmologist uses it to examine the cornea, aqueous humour and the retina. There are also advanced ophthalmoscopes that can be worn just like a headset. They offer a better field of view and so cost a lot more than the standard ones.

Many ophthalmic instrument tables have slit lamps attached to them. Slit lamps are used to examine the interior of the eye in great detail. Slit lamps have a high-powered microscope and a light source. The scope is binocular and has a high magnification power of around 40x to 60x. They are mostly used to spot foreign infection-causing germs or bacteria in the eye. Some slit lamps also have digital cameras attached to them for documenting the infectious elements.

Maintaining ophthalmic refraction units is a very hard and minute job as these instruments are prone to attract bacteria from the patients. Moreover, there can be fungus growth on the lenses which cannot be easily perceived. Thus it is equally important to regularly clean all the ophthalmic equipment with paraldehyde or other similar substances to kill the bacteria and stop fungus growths.
