LASER- Light Amplification by Stimulated Emission of Radiation:-
We now a days always heard about LASER, then what is this laser. It is a narrow beam of one wave length with coloured parallel rays of light and it can easily pass through the tissue or any object.
Several use of Laser in eye treatments which is very effective and safe in result. The main mechanism of laser is to accumulate of light by tissue and converted into heat by this phenomenon that tissue can change its state.
Use for Retinal Disorders:-
The very common condition is Diabetic Retinopathy in which retina has blood haemorrhages, weak blood vessels, so laser will apply to control this eye condition from more deterioration, macular diseases like macular oedema or swelling, age related macular degeneration (age related effects on retina).
Use for Retinopathy of Prematurity (ROP):-
This condition just after birth of new born baby with low birth weight and also stays in oxygenation for prolong time due to any disfunction of body, for this reasons that baby’s retina may weak in nature, it may be a risk factor of retinal detachment or neovascularisation. Laser is using to control further damage of vision.
Use for Glaucoma:-
A vital role has to control the eye pressure, use laser to make a tiny hole on edge of Iris, clinically named Peripheral Iridectomy and Laser trabeculoplasty.
Use for Capsulotomy:-
After few years of cataract surgery, the posterior capsule where IOL is placed may be hazy or thick in nature, the laser cleans that capsule so the vision of that person can also improve as before.
Use for Cataract Surgey:-
Laser is used to make a small cut to enter into the eye and also to break the nucleus of our natural opaque lens. Though the blade will use but the power of ultrasound use is less, recovery time is minimum.
Use to Remove Refractive Error or Eye Glass Power:-
A very commonly known to general people with the help of laser correction of eye power. LASIK (Laser Assisted in Situ Keratomileusis), in this case a thin flap of cornea is done by blade or keratome or femtosecond laser and reshape the cornea by removal of some tissue using excimer laser.
So, we have some brief idea that laser has many useful acceptable role in eye treatments in the world of Ophthalmology.
