National eye hospital lasers using for eye treatment
01. Nd .YAG laser
02. Argon laser
YAG laser - use for lens capsule cataract removal
One month or year after cataract surgery posterior capsule ( also called thin membrane around the lens - in cataract surgery they removed) become cloudy
Nd .YAG laser use for removed posterior cloudy capsule - this help to patient vision improvement
Risk - increase used of laser can be retina exposed and damaged the retina
Normally 50 Pulse used for treatment
1 - 2 get vision improvement
Painless
Argon laser
Treatment for glaucoma, diabetic eye disease, retinal holes and tears
Narrow-angle glaucoma treatment:
improves the drainage of the aqueous humor
Repairing retinal tears and small retinal breaks:
Small tears in the retina in individuals with high myopia
prevents the risk of retinal detachment (repaired with an argon laser)
Proliferative retinopathy in people with diabetes:
Abnormal blood vessel growth over the retina in people with diabetes with uncontrolled sugar levels can cause swelling and scarring of the retina. These blood vessels can be burnt with an argon laser, thus improving vision.
Choroidopathies(birth defects)
abnormal leaky blood vessels to grow over the retina. This causes swelling over the retina. These can be burnt with an argon laser
In Argon laser Treatment use eye drop for pupil dilated and anesthetic eye
Use slit lamp - high intensity light beam onto the retina
Vision blurred 3 to 4 hours
LASIK laser
Eye surgery- cutting, gliding cornea for correct refractive errors- hypermetropia, myopia and astigmatism also cataract surgery
