How Eye surgery works?
Eye surgery is one of the most intricate and delicate surgical procedures. It might be performed to treat an eye disease and to correct or improve vision in the affected eye. These types of surgeries require the expertise of an experienced eye surgeon or an ophthalmologist as the eye is one of the most delicate and sensitive vital organ of the body.
Eye surgeries employ various techniques and approaches depending on the disorder or the location of the deformity in the eye region.
Eye surgery may be performed using conventional open-type surgery or a minimally invasive surgery technique as well. Nowadays the use of laser technology in eye surgery is gaining quite a popular demand.
Eye surgery procedures
There are a number of different eye surgical procedures and the methods of performing these surgeries are also varied.
These are a few commonly performed eye surgeries along with their procedure techniques:
Laser eye surgical techniques use a fine beam of high-frequency laser light to perform delicate surgeries in the eye. Lasers can be used to treat refractive and non-refractive eye conditions. Corneal laser surgery uses a beam of laser to re-contour the surface of the eye. This procedure is used to treat short-sightedness (myopia), far-sightedness (hypermetropia) as well as distortion in the eye's curvature (astigmatism).
This is the preferred option for surgery technique in case the patient wishes to avoid using eyeglasses to improve the vision in the eyes.
A cataract causes the crystalline eye lens to get cloudy or opaque. Cataract is often caused by aging, trauma or an eye disease and prevents the light from outside in making a clear image at the back of the eyeball on the retina. In case the condition gets severe as to result in loss of vision in the affected eye it might be required to surgically remove the optical lens and replace it with an artificial intra-ocular lens (IOL).
Due to the high number of cataract cases this type of surgery is one of the most common eye surgeries in the world.
Glaucoma consists of a number of diseases that affect the optic nerve in the eye, resulting in loss of vision caused due to a raised intra-ocular pressure (IOP). There are a number of different glaucoma surgeries that are either performed singularly, or in combination with others to allow the excessive aqueous humor (eye fluid) to drain from the accumulated area and lower the pressure on the optic nerve.
