Surgery to remove a cataract is the only way to get rid of a cataract. This surgery works well and helps people see better. But surgery is often not needed or can be delayed for months or years. Many people with cataracts get along very well with the help of eyeglasses, contacts, and other vision aids.
Whether surgery is needed for an adult with cataracts depends on the degree of vision loss and whether it affects quality of life and ability to function.
The choices for treating cataracts in children depend on how likely the cataracts are to interfere with the development of normal vision.
Sometimes a cataract needs to be removed because of another eye disease, such as diabetic retinopathy or macular degeneration. In some cases the cataract has to be removed so that the eye specialist can treat the retina, the nerve layer at the back of the eye.
Laser eye surgery is the process of reshaping the front surface of the eye (the cornea) in order to correct minute imperfections which affect the eye's ability to focus.
Depending on the treatment deemed suitable, a thin layer is gently lifted away from the surface of the eye so the laser can access the layer below and correct the prescription with pinpoint accuracy.
The layer is carefully set back in place, and sometimes protected with a clear bandage contact lens for 3-5 days while the eye naturally heals. All this is carried out using bladeless laser technology to eliminate potential complications and improve the results for every patient we treat.
Retinal diseases affect the retina — a layer of nerve tissue lining the back of the eye that senses light and sends images to the brain. The central part of the retina is the macula. The macula is responsible for central vision; the remaining retina outside the macula provides "side" or peripheral vision.
The back of the eye is filled with vitreous humor or simply "vitreous", a gelatinous material that gives an eye its shape. With aging, the vitreous gel may liquefy, collapse, and pull away from the retina in the process called posterior vitreous detachment (PVD). Some patients are susceptible to develop retinal problems at the time of PVD, such as a retinal tear.
There are many other retinal diseases; some involve only the macula, for example, age-related macular degeneration, macular hole, or a macular pucker (epiretinal membrane); others can impact the entire retina, for example, retinal detachment or diabetic retinopathy.
Glaucoma, otherwise known as "Kala Motia" is an eye disease in which there is an increase in pressure inside the eye. Just as some people have high blood pressure, in the same way a glaucoma patient has high eye pressure..
If the eye pressure remains high for a long time it damages the optic nerve which carries the light sense from the eye to the brain. This damage to the nerve is irreversible and leads to permanent and incurable blindness. That is why glaucoma is a dangerous disease of the eye and has been labeled as "lurking thief of vision". Glaucoma is the second leading cause of blindness in the world with 70 to 105 million people affected worldwide (WHO).
