Cataract Surgery

Image title

When the eye’s original lens will becomes clouded, then it was termed as cataract. Most of the cataracts are the result of natural process of the aging. Others can be present at the birth or develop as the result of the physical, drug, or chemical injury. By performing the cataract surgery, the cloudy lens is removed or cleaned out & replaced by the clear manmade lens. Most of the cataract surgeries were performed by a technique known as phacoemulsification also known as "small cut (incision) cataract surgery." The cut (incision) will be smaller, due to the harder center section of lens was liquefied & then vacuumed out. Under the local anesthesia, doctor will perform phacoemulsification, by making a small opening on side of the cornea.
A device which sends out ultrasound vibrations is inserted into the eye & breaks the lens into small minute pieces. These fragments were then removed by the suction by a small cut in the eye. Your eye doctor may also use a laser to make the incision. The hope was that a more precise incision will additionally improve the recovery time from the cataract surgery.
After the cataract was removed, doctor generally replaces it with a new, man-made lens known as intraocular lens or IOL. This technique is called as "intraocular lens implantation." The IOL is a clear plastic, acrylic, or silicone with a optical power chosen by the doctor to help in restore the normal vision, usually minimizes the dependence on the eye glasses after surgery. This lens is permanent & needs no special care.
The IOL focuses light into the retina that helps to improve  vision. Even though if natural lens is replaced with intraocular lens, you perhaps will need a new eyeglass prescription. Yet, most of the people can see fairly good at a distance without having glasses after a recent cataract surgery with the cataract lens replacement. Cataract surgery was performed as an outpatient procedure in an operating theater. So there was no hospital stay. The actual operation was usually lasts less than a one hour. It is safe & in several ways it is desirable to be awake with low level of sedation during the operation. A sedative is given & numbing drops were introduced into the eyes. Another choice is to use a novacaine injection was placed around the eye. General anesthesia is occasionally used in the cataract surgery. Doctors generally won't remove the cataracts in both of the eyes at the same time. If you need surgery for both of the eyes, you need to be scheduled for separate surgeries, generally a few weeks after.
