Light has the possibility to reach the internal structures of the eye in a non-invasive manner. Light in the domain of optometry is being used since 1946. It was Gerd Meyer-Schwickerath, the German ophthalmologist who had used light for coagulating the human retinal tissue. This was performed by focusing xenon arc lamp light, to produce tiny burns within the retina region. This effectively sealed off all retinal tears. The optometry was revolutionized by this technique. One can study the ophthalmic course from the reputed institution and enjoy a flying career.
Using new technology and laser used optometry devices
It was in 1960 that the first laser had been demonstrated by Theodore Maiman. It went on to become a highly effective and efficient tool when providing corrective eye treatment is concerned. Modern technology has helped physicians to make use of different types of lasers for treatment purpose. Each of them tends to come with its own uses and technical specifications. There are about five common types of lasers that are used in the field of optometry.
Studying the course can help the candidates to know more about the laser treatment procedures.
This solid-state laser is regarded to be a commonly used one in ophthalmology and other fields. They have a wavelength of 1054 mm. They can be operated both in continuous and pulse model. The common surgery where it is used is peripheral iridotomy and cataract surgery. For photocoagulation, such lasers having 532mm frequencies are used.
YAG laser is beneficial for patients suffering from cataract.
They are considered to be the most used optometry lasers. These lasers tend to shoot out energy rather than burning through the matter. This helps the eye surface tissue molecular bonds to break apart, thus integrating into air. No burning is involved. Such lasers can help eliminate thin eye material layers, without actually impacting remaining tissue. In precision surgeries, these are used.
These popularly used lasers are quite beneficial for precision surgeries.
Microkeratome femtosecond laser
Here, microkeratome is considered to be a mechanical shaver to help cut thin flap from the cornea’s exterior layer, thus allowing laser surgery. This laser has been designed for foregoing the blade, to make use of ultrashort pulse femtosecond lasers for creating the cut. Risks that were prevalent in microkeratome blade method are minimized drastically.
This type of laser is useful to cut down risks and provide better treatment.
They are a gas based laser having krypton ions combined with electronic discharges. These lasers are used for treating macular degeneration. It is considered to be a disease which takes place among elderly people causing loss of vision central field because of damaged retina.
This laser treatment can help the elderly to see again.
This laser is emitted at different wavelengths in ultraviolet spectrum. They are used commonly in retinal phototherapy techniques. These lasers are utilized for panretinal photocoagulation to prevent retinopathy from creating further damage.
These lasers can be used for providing open angle glaucoma treatment.
Lasers are being used in the field of optometry since the 1960’s. However, with constant advancements being made in science and technology, there is required talented and skilled professionals who can use such advanced techniques comfortably and correctly. Hence, undergoing ophthalmic programs can help achieve a flying career.
