Diploma in Optometric: Know The Five Common Lasers That Are Used in Optometry

Diploma in optometric is being availed by candidates in huge numbers across the country, due to the increasing demand for qualified optometrists and the lucrative pay package and fees offered to them. Before going ahead undergoing the course, it will be useful to know why Optometry is in demand and the five common laser types used for treatment purpose.

History of Optometry

Light can easily reach non-invasively any part of the internal eye structure. Light is being used in optometry field dating back to 1946, with light being used for coagulating human retinal tissue by Gred Meyer Schwickerath, the German Ophthalmologist. This was done by focusing xenon arc lamp light, thereby producing tiny burns within the retina region to seal off retinal tears. The optometry world has been revolutionized by this technique. In 1690, once the initial laser had been demonstrated by Theodore Maiman, this became an effective tool to provide patients with corrective eye treatment. Modern technology has come up with wide range of lasers, with each having its own uses and technical specifications. One should visit the best optometry college to learn in details about this subject.

Five common laser types used in optometry

  • Excimer Laser: These are commonly used in the field of optometry. Rather than burning through matters, energy is shot out to break apart the surface tissue of the eye’s molecular bonds. The molecules are found to vanish into air, with no burning being involved. It can also effectively eliminate thin eye material layers without actually impacting remaining tissue. Hence, such laser types are used for carrying out precision surgeries.
  • YAG Laser: It is considered to be solid state laser and among the common types used in different medical fields. It comes with 1054mm wavelength and operated in continuous and pulsed mode. It is used in commonly operated eye surgeries like peripheral iridotomy and cataract surgery. They are used for photocoagulation and are of 532 mm wavelengths.
  • Argon Laser: William R. Bennett had discovered this laser process. it is at various wavelengths that argon laser could be emitted in ultraviolet spectrum. It is used commonly for retinal phototherapy procedures. Those suffering from diabetic retinopathy can avail this type for panretinal photocoagulation to prevent retinopathy from carrying out further damage. This laser type is also used for providing treatment to open angle glaucoma.
  • Krypton Laser: These are gas laser type that has been developed using krypton ions along with electronic discharges. These are used commonly for treating macular degeneration, a type of disease, which affects mostly elderly people, resulting in loss of vision’s central field, caused by retina damage.
  • Microkeratome femtosecond laser: It is regarded to be a mechanical shaver to cut thin flaps from the cornea’s exterior layer for allowing laser surgery. It has been designed for forgoing the blade as well as to make use of ultrashort pulse fmtosecond lasers for creating cut. Risks can be minimized with this new method in microkeratome blade method.

Those having undergone Diploma in optometry can prove to be experts in the field.

Importance of optometry courses

Candidates undergoing the Optometry diploma courses from a reputed institution will be taught practical and theoretical concepts about the above mentioned surgeries along with other things, required treating patients.
