Know The Various Types of Ophthalmologist Instruments

Ophthalmological instruments are specialized medical instruments used for the examination of the eye and its surrounding region. The most common of these instruments are the intraocular pressure monitor, the light emitting diode, the otoscopy, the corneal camera, the sclera and strong pieces. All these instruments have their own specific roles and serve different purposes. However, they all work on the basic principle of viewing the eye, measuring the intraocular pressure (IOP), the flow of arterial blood through the arteries near the eye, visualizing any damage in the retina and testing for abnormalities of the eye.

Amongst the various ophthalmic devices are the various types of forceps and gloves that are used to manipulate the retina, manipulate it and check for any abnormal conditions. The most commonly used forceps instruments are the retractor, the intercanula distance, the retractor, the tweezers and the optokinetic forceps. All these instruments, however, fall under the micro-surgical instruments group.

Understand the micro-surgical instruments

Micro-surgical instruments fall into two categories, namely, single-use instruments that need a needle to insert and remove the instruments from the eye. The single-use devices are very small and are used in a single action. Such instruments include eyelid specula, the grade diopter and the eyelid forceps. The instruments that need a needle are the fundus speculum, the eyelid suction device, the midline iris extender.

Single-use forceps

The single-use forceps range includes the puncture tube, the arnoscope, the otoscope, the nasal cannula and the otoscopic radio bulb. The other category is that of the needle holders. Needle holders can be either the mechanical or the electrical type. The mechanical needles have the use of gravity, while the electrical needles have the use of an electrical current. It is also worth mentioning that there is an entire sub-genre of the instruments under the name of "needle devices".

Injector devices

The other category of ophthalmic instruments includes the injector devices. This is a broad category and includes the syringe, the dropper, the lens root canal irrigation and the lens implant manufacturer. In fact, the injector devices are also grouped into three sub-categories. The first sub-category comprises the micro injector; the second sub-category is the intraocular pressure pump; and the third sub-category comprises the nontheatrical pump. The ophthalmic syringes are usually pre-filled with the saline solution and sterile needles are used to inject the contents.

Intramuscular pressure gauge

Another important device in the category of ophthalmic instruments is the intraocular pressure gauge. This instrument is used to monitor intraocular pressure. Various parts of this gadget include the probe, the intraocular pressure transducer and the monitor. The monitor shows the pressure within the eye as well as the normal pressure.

Intramuscular pressure transducer

The next gadget in the list is the intraocular pressure transducer. This instrument is used to measure intraocular pressure and is mostly used in the laboratory. Various parts of this gadget are the ocular bulb, the pressure transducer and a cuff connected to the ocular bulb. The cuff is placed around the eye and the ocular fluid passed through it. The cuff then measures the pressure change as the retina varies.

The other most important types of ophthalmic instruments are the various retinal probes. These instruments are mostly used in order to take a microscopic image of the retina. They can be used for various different purposes such as checking the health of the eye, or they could even be used for detecting the abnormalities of the retina. Some of the other instruments include the optoelectronic chart reader, the magnifier and the eyeglass lens mount.

Eye pressure catheter

Another very important instrument used in order to monitor the health of the retina is the eye pressure catheter. This device has two handles and is used for passing anesthetic gas. The catheter passes through a hole in the eye. It can either be fixed to the top of the eyeball or can be placed on the inside of the eyelid. It is placed behind the retina and slowly lowered to the back of the eye.

In addition to these various ophthalmological instruments there are various types of glasses used to correct various vision problems. There are some specific types of corrective lenses such as multifocal lenses, bifocal lenses, etc. Some people use eyeglasses instead of contact lenses in order to increase their ability to see clearly. It is important that you consult with your optometrist so that he/she can advise you as to what type of corrective lens is best for your specific case. He/She can also help you in finding the best glasses that will be most comfortable for you. Also, he/she may recommend an appropriate pair of frames.
