Refractive surgery is conducted by adjusting the focusing ability of the eye, which is done by reshaping of the cornea. Most people are freed from glasses after the surgery but some continue to need glasses, especially for night driving and reading.
You or one of your family members might have developed cataracts and you may be wondering if the decision to go for cataract surgery is the right one. The first thing that you should know is cataract surgeries are one of the safest and most effective eye surgeries.
cataract surgery is done to separate the lens capsule and the cataract. In most surgeries, the lens is replaced with an intraocular lens implant or IOL. If this replacement cannot be done, eye glasses become necessary. There are mainly two types of cataract surgeries.
The function of the eye is somewhat similar to that of a camera that records images. As the light enters the eyes, it passes through the cornea, the transparent fluid in the eye (known as aqueous humor), the pupils and then into the lens. The lens then bends the light so that it focuses the image of the objects on the retinal lining at the back of the eyes. From here, the formed image travels through the cells of the retina to the optic nerve. This carries the image to the brain, which processes it.
Most people wish to get rid of their prescription glasses but fear the thought of a blade entering their eyes during a LASIK procedure. If this is the only thing that is keeping you from going for a LASIK, you now have a solution at hand. IntraLase uses no blades to perform LASIK surgery on your eyes.
Lens implants are intended to replace your natural lens with small slices of plastic that are specifically designed for the purpose. These 'intraocular lenses' are typically silicone or acrylic. Once they have been implanted you will not be able to feel them, since they are implanted inside the eye, in a spot that has no nerve endings.
