How A Cornea Specialist Operates.
Some debris enters your eyes after a gust of wind blows up some dust into the air. Immediately, your eyes shut and you start rubbing them while tears flow down your cheeks. The part of the eye that the debris came into contact with is called the cornea. It is the foremost clear part of the eye that covers it. When the cornea(s) get injured or need medical attention from a disease affecting it, one is referred to a cornea specialist. This is an eye doctor who has studied this area of the eye and provides a wide range of treatments in relation to this part of the eye. These can include minor to major treatments including eye rinses to surgery.
A cornea specialist has to have a medical degree first and then gets further medical specialization in this area of the eye. They belong to the wider group of eye doctors called ophthalmologists. The cornea functions in two major ways, the first and most basic is to focus light into the eyes for vision. They allow light to enter into the eye and refract light into the lens, which then focus the light rays onto the retina, which sends the impulses of light through the optic nerve into the brain which translates them into images. The other function of the corneas is to protect the eyes from debris and or injuries. This function is shared with the eye lids.
The most common abnormality affecting the corneas are short-sightedness or myopia where the cornea is curved too much causing images which are far to be blurry. The other condition is long sightedness or hyperopia, where the images which are near are blurry but those that are far are clear. The cornea in this case is too flat. The corneas are also susceptible to diseases which need a cornea specialist to take care of.
When a cornea is injured slightly, healthy cells come over it and cover the injury to avoid infections. However, when the corneas are injured extensively by debris , which tears them deeply, a cornea specialist will come into the picture to remove the debris and perform procedures that will heal the eye. Sometimes, a cornea transplant will be needed to replace the damaged corneas.
Other diseases that a cornea specialist will deal with are corneal infections or keranitis caused by foreign objects getting into the tissue or bacterial and viral infections. These infections can cause scarring of the cornea, which impairs vision and at worst erode the cornea which could necessitate corneal transplants. Minor infections can be treated with antibiotics, eye drops or steroid eye drops to reduce inflammation.
The other major corneal disease is corneal dystrophy, a condition that is caused by build up of cloudy material in the cornea affecting vision. They can cause total vision loss or none at all depending on the dystrophy as there are as many as twenty of these.
Whenever one gets any of these eye conditions, you know who to see for prompt and correct treatment.
