First of all you should know what the cataract is. A cataract is an opacity of the lens of the eye, which is located between the front and back areas of eye surgery. Cataract is an operation that successfully restores vision.
You should know that cataract surgery in Delhi is done correctly, 9 out of 10 people who undergo cataract surgery recover very good vision, somewhere between 20/20 and 20/40. During surgery, an eye doctor removes the opaque lens of the eye and replaces the lens with an artificial lens.
Cataract surgery will be important to improve your vision. Cataract surgery is a simple, relatively painless procedure to recover vision. All surgery involves some risk. You should choose an experienced surgeon, which will reduce the risk of something going wrong.
When is it time to have cataract surgery?
You and your ophthalmologist must work together. If cataract progress is rapid (complications of diabetes), do not wait for cataract surgery. But, if your vision is still pretty good, you may not need cataract surgery right away.
It is necessary to continue visiting your ophthalmologist regularly. You should know that some cataracts never reach the stage where they should be eliminated.
With cataract it is the best time for surgery is individual. Think about how cataract affects your life. If the cataracts do not bother you a lot, you can wait a while for the surgery.
Think about surgery when your cataracts have progressed enough to seriously affect your vision. If the cataract has a significant effect on your diaries is activated, you should have cataract surgery as soon as possible.
In some cases a cataract should be removed even if it does not cause major problems with vision, but it interferes with diabetic retinopathy or retinal detachment or some other eye problems. You can have cataracts in both eyes. You will have two separate surgeries.
How is surgery performed?
In some cases, a cataract may be removed without the implantation of an artificial lens. During surgery in most cases the ophthalmologist removes the opaque lens of the eye and replaces the lens with an artificial lens.
Before cataract surgery, the ophthalmologist measures the size and shape of the eye to determine the proper power of the lens implant. This procedure is a painless, this is an ultrasound test.
Local or general anesthesia
Cataract surgery takes less than an hour. Most patients are awake and only need local anesthesia. In rare cases, some people may need general anesthesia.
The methods used to eliminate cataracts
Surgical methods used to eliminate cataracts include: phacoemulsification and extracapsular cataract extraction.
The surgeon removes phacoemulsification from cataracts, but leaves most of the lens capsule in place.
During phacoemulsification, the surgeon makes a small incision, approximately 3 mm, where the cornea meets the conjunctiva and a probe is inserted. Probe transmits ultrasound waves, to break the cataract and the aspiration to the fragments. The lens capsule provides support for the lens implant.
If phacoemulsification cannot be done, another method is used. The surgeon can perform an extracapsular cataract extraction. Extracapsular extraction of the cataract requires a larger incision, approximately 10 mm. Surgeon opens the lens capsule, removes the nucleus in one piece and aspirates the lens of the smoother cortex, leaving the capsule in place.
When the cataract has been removed by one method, a transparent artificial lens is implanted in the empty crystalline lens capsule. This implant is an intraocular lens, it is made of plastic, acrylic or silicone. Intraocular lens becomes a permanent part of your eye. You will have to read the glass after the surgery.
Intraocular lenses are being developed all the time to make surgery less complicated and lenses more useful for patients. New intraocular lens allows patients to see at all distances, not just one.
Another new intraocular lens blocks both ultraviolet rays and blue light rays, indicating the research may damage the retina. There are different multifocal intraocular lenses, and blue blocking lenses. Multifocal lenses offer vision both near and far. Glow can be a problem with multifocal lenses.
After cataract surgery in Delhi
With phacoemulsification surgical incisions are very small. If everything goes well, you get better quickly and your vision will begin to improve in a few days. If you had extracapsular extraction of the cataract, which requires a larger incision of complete healing can take up to eight weeks.
You can go home the same day of surgery. You should know that you cannot drive, so be sure to arrange a trip home. You must provide the necessary help, since the doctor can limit some activities for a few days. You will see your doctor the next day, the next week and after one month.
You will feel itching and mild discomfort for a couple of days after surgery. Do not rub or press the eye. You can use a protective shield on the day of surgery. Ophthalmologist can prescribe medications to prevent infection and control eye pressure. After a few days, all the discomfort should disappear. In most cases complete healing occurs within eight weeks.
You should contact your doctor if you have the following symptoms. These include: loss of vision, increased redness of the eye, pain that persists despite the use of medications, flashes of light or several floaters in front of your eyes, nausea, vomiting or excessive coughing.
Ophthalmologist will let you know when your eyes have healed enough for you to get a definitive prescription for glasses. Most people have to wear glasses after cataract surgery. Astigmatism is a common complication of surgery, but it is a minor problem when the procedure involves a small incision.
If you have cataracts in both eyes, after the first eye surgery it is necessary a month or two before you can schedule surgery for the other eye.
Complications after cataract surgery
Complications after cataract surgery are: swelling, inflammation, infection, bleeding retinal detachment and glaucoma. Complications after surgery are rare and can be treated. In some cases, cataract surgery does not improve vision due to underlying eye damage (glaucoma or macular degeneration).
If other eye problems are present, they should be evaluated and treated, before deciding to have cataract surgery.
The second cataract occurs when the back of the lens capsule becomes opaque and makes it difficult to see. This condition is called opacification of the posterior capsule. Posterior opacification of the capsule may appear months or years after cataract surgery.
The treatment consists of a technique called laser capsulotomy. This procedure is a brief and painless outpatient procedure that usually lasts less than five minutes. After the patient’s stay procedure in the doctor’s office for about an hour to make sure that the eye pressure does not increase? In some people, YAG laser surgery can raise eye pressure.
