Despite rapid strides being made in the field of cataract eye surgery in the last few decades, it continues to remain the leading cause of reversible blindness in our country. We at The Eye Foundation have been pioneers in the field of cataract surgery offering cutting edge technology and a high standard of care to a large population.
The natural crystalline lens of our eye is clear which allows light to be focused clearly on the retina. With ageing, this lens loses its transparency and gradually becomes clouded thereby impairing vision.
Cataract is characterized by a painless, progressive decline in vision. Apart from decreasing vision patients with cataract even in the early stages may experience increased glare while driving at night or reading in dim illumination, difficulty in differentiating objects at a distance and the need for frequent change of glasses.
Cataract surgery can be performed at any stage once it starts interfering with the daily activities of the individual. With the advent of techniques and technology, cataract surgery can be performed in a safe and effective manner even in the early stages and one need not wait for the cataract to mature. In fact more advanced and harder cataracts are associated with an increased incidence of complications earlier the better.
In the very early stage of cataract corrective glasses can be given. Surgery is the only and definitive treatment modality for visually significant cataracts.
Over the years the size of the corneal incision made during cataract surgery has considerably reduced leading to faster visual recovery and reduced postoperative discomfort
This is the latest advancement in the field of cataract surgery where a laser is used to help make incisions and break the cataract into small pieces. This has greatly enhanced the precision and safety of cataract surgery making it bereft of any significant complications.
Monofocal IOL A majority of intraocular lenses implanted are monofocal lenses. These lenses have the capability of focusing light from a single distance. Normally distant objects are clear and one requires glasses for reading. The monofocal lenses are either rigid non foldable or foldable. The foldable lenses can be inserted through a small wound allowing faster visual recovery and reduced postoperative discomfort. Toric IOLs In certain situations, the patient may have a high cylinder or preoperative bend of the cornea. Monofocal lenses are unable to compensate for this, hence the patient requires glasses for distance vision postoperatively in addition to a reading power. Toric IOLs have the ability to correct the eye power both at the corneal and lenticular plane, thereby correcting the cylindrical power. Multifocal IOLs Multifocal lenses have different segments which focus light rays from various distances onto the retina. This affords correction for near, intermediate and distant vision to the patient. Most often patient can manage his activities without glasses for all distances.
You may, if you are over 40 years of age and have blurred vision, light sensitivity or glare, poor night vision or fading of colors. These symptoms may differ based on the sub type of cataract.
During your visit to The Eye foundation, first your vision will be checked by trained optometrists. Your pupils will then be dilated and you will be examined by a consultant, who will then discuss the nature of your cataract and your surgery options with you. The consultant will also evaluate your retina or the nerve of your eye. Prior to your cataract operation, you will need to undergo some routine medical and blood tests and an A-scan that will help the doctor to determine the power of the new lens to be implanted in your eye. You can then choose a convenient date for your eye surgery. Our range of hospital available in Bangalore, Coimbatore, Kochi
No, the procedure is a simple day care one. The area surrounding your eye will be cleaned, and sterile drapes will be placed over you, exposing only the eye to be operated on. You might have a local anesthetic, which involves a small injection around your eye to keep the eye muscle relaxed during surgery or just drops instilled in your eye to numb it. This makes the surgery completely pain free. The whole process is usually under 10 to 15 minutes.
It is good to wash your face thoroughly with soap and water before coming for surgery. Use the antibiotic eye drops prescribed to you before the surgery. You can eat a light breakfast on the morning of the surgery.
After surgery a bandage or shield will be placed over your eye. You can resume normal, moderate activity as soon as you feel up to it. You should wear protective glasses while going out during the first week. You can bathe carefully from below your neck but do not wet the operated eye for 15 days. You are advised to gently clean the eyelids with a piece of cotton boiled in water or a sterilized tissue. There are no diet restrictions following the surgery.
You can return home soon after your cataract operation. Surgeon will see you before discharging. However, if you desire to stay back with an attendant you can stay overnight in comfortable inpatient rooms at no extra charge.
In some cases, the patient is able to see clearly immediately after the surgery. Although, for most it takes about two to three days.
You may need to wear glasses after the procedure. If a monofocal intraocular lens is implanted, you will require glasses for reading. A multifocal intraocular lens implantation on the other hand will give you freedom from glasses for a majority of your distance, intermediate and near activities. Most often you can manage without glasses.
The implanted intraocular lens is permanent and lasts for the entire lifetime.
Usually both the eyes are not operated on the same day. Once the visual recovery of the first eye is complete, the second eye surgery can be planned. Most of our patients undergo second eye surgery after a week.
