,we call the condition as Cataract. It occurs normally after 50 years of age but may also occur any time since birth to old age.
Cataract with age is just another change in the aging process but when seen in youngsters, it can be due to a host of other diseases of the eye for example uveitis, general diseases like the diabetes, heredity, injury, radiation, infections and long term medications.
Glasses can provide support in the early stages. Cataract surgery is done if the specs fail to deliver the needed vision. Cataract surgery by an expert eye specialist is the only option then. Other things like glaucoma, uveitis, retinal management, expected outcome of operation, common and worst possible complications, safe time period to wait for surgery, expenditure, rest and precautions after surgery etc. can also be consulted by an eye specialist. For common information you can call to hospital counselor
Robocat*- or Robotic Cataract Surgery or Femto assisted Laser Cataract Surgery is latest, safest, fast and reproducible procedure in the world as on date. It creates blade less entry, astigmatic correction, circular opening in cataract and multiple division of cataract without putting any instrument in the eye, with exact size and location every time with continuous monitoring by OCT and computer. That is why it is also called robotic cataract surgery. Manually no surgeon can achieve the same size and location in every case. About 10% surgery of final cleaning and IOL implantation is still manual.
Phacoemulsification: It is an extremely safe and advanced technique to remove cataract. By ultrasonic vibration and cutting. It breaks and emulsify the cataract to aspirate it. This is done through a very small incision that allows the phaco tip 1.4 mm or 2.8 mm. Through this small incision foldable intra-ocular lens is inserted.
This is done by few drops of anesthesia. No injection or bandage is required. And the patient gets a clear vision immediately after the cataract surgery. Office work, albeit in a clean environment, can be done just after a day. Field work can be done after 10 days.
The advantage of laser and Phaco is clear: Quick & good vision without anesthetic injections, bandage and troublesome bed rest.
Lens is extremely important because it alone makes the eyes a 'near-natural' one. Without IOL patient has to see through the external agency of glasses which are relatively much heavier and cumbersome for the sensitive eyes.
IOL is placed inside the eyes, mostly in the same capsular bag where the natural lens is placed. Hence it does not get affected by dust, smoke or water splashes. Unlike natural lenses IOL's are of fixed power. They give good vision only up to a fixed distance only. And specs can be called into play to rectify the lacunae.
A good IOL should be pre-loaded, foldable, square edge, aspheric, multifocal, with or without toric and aberration correction. With multifocal iol you can do almost all your job without specs! And even if the specs are needed, the dependence upon specs is reduced considerably.

A cataract is a clouding of the lens in the eye that affects vision. Most cataracts are related to aging. Cataracts are very common in older people. By age 80, more than half of all Americans either have a cataract or have had cataract surgery. A cataract can occur in either or both eyes. It cannot spread from one eye to the other.
Initially the blurry vision can improved with the use of glasses and good lighting for reading. Over time your vision will continue to deteriorate, the cataracts will not go away and you may wish to proceed with surgery. The cataract is usually removed when it starts to significantly affect your daily life.Image of the eye
The lens is a clear part of the eye that helps to focus light, or an image, on the retina. The retina is the light-sensitive tissue at the back of the eye. In a normal eye, light passes through the transparent lens to the retina. Once it reaches the retina, light is changed into nerve signals that are sent to the brain. The lens must be clear for the retina to receive a sharp image. If the lens is cloudy from a cataract, the image you see will be blurred.
The lens lies behind the iris and the pupil. It works much like a camera lens. It focuses light onto the retina at the back of the eye, where an image is recorded. The lens also adjusts the eye’s focus, letting us see things clearly both up close and far away. The lens is made of mostly water and protein. The protein is arranged in a precise way that keeps the lens clear and lets light pass through it.
But as we age, some of the protein may clump together and start to cloud a small area of the lens. This is a cataract. Over time, the cataract may grow larger and cloud more of the lens, making it harder to see.Researchers suspect that there are several causes of cataract, such as smoking and diabetes. Or, it may be that the protein in the lens just changes from the wear and tear it takes over the years.
Clumps of protein reduce the sharpness of the image reaching the retina. The lens consists mostly of water and protein. When the protein clumps up, it clouds the lens and reduces the light that reaches the retina. The clouding may become severe enough to cause blurred vision. Most age-related cataracts develop from protein clumpings.
When a cataract is small, the cloudiness affects only a small part of the lens. You may not notice any changes in your vision. Cataracts tend to “grow” slowly, so vision gets worse gradually. Over time, the cloudy area in the lens may get larger, and the cataract may increase in size. Seeing may become more difficult. Your vision may get duller or blurrier. The clear lens slowly changes to a yellowish/brownish color, adding a brownish tint to vision.
As the clear lens slowly colors with age, your vision gradually may acquire a brownish shade. At first, the amount of tinting may be small and may not cause a vision problem. Over time, increased tinting may make it more difficult to read and perform other routine activities. This gradual change in the amount of tinting does not affect the sharpness of the image transmitted to the retina. If you have advanced lens discoloration, you may not be able to identify blues and purples. You may be wearing what you believe to be a pair of black socks, only to find out from friends that you are wearing purple socks.
The term “age-related” is a little misleading. You don’t have to be a senior citizen to get this type of cataract. In fact, people can have an age-related cataract in their 40s and 50s. But during middle age, most cataracts are small and do not affect vision. It is after age 60 that most cataracts steal vision.
Wearing sunglasses and a hat with a brim to block ultraviolet sunlight may help to delay cataract. If you smoke, stop. Researchers also believe good nutrition can help reduce the risk of age-related cataract. They recommend eating green leafy vegetables, fruit, and other foods with antioxidants.
If you are age 60 or older, you should have a comprehensive dilated eye exam at least once every two years. In addition to cataract, your eye care professional can check for signs of age-related macular degeneration, glaucoma, and other vision disorders. Early treatment for many eye diseases may save your sight.
Cataract is detected through a comprehensive eye exam that includes: Visual acuity test. This eye chart test measures how well you see at various distances. Dilated eye exam. Drops are placed in your eyes to widen, or dilate, the pupils. Your eye care professional uses a special magnifying lens to examine your retina and optic nerve for signs of damage and other eye problems. After the exam, your close-up vision may remain blurred for several hours. Tonometry. An instrument measures the pressure inside the eye. Numbing drops may be applied to your eye for this test.
Your eye care professional also may do other tests to learn more about the structure and health of your eye.
