A cataract is a progressive clouding of the human lens inside the eye. The cataract procedure is fast, comfortable and very successful.
If you have been told that you have a cataract, there is no need to be overly concerned as you are not alone. Each year in the United States, more than 2.5 million people have cataract surgery. Thanks to advanced surgical procedures and technology at Visiomed Eye Laser Clinic, cataract surgery is not only one of the most frequently performed surgical procedures, but it is also one of the safest and most successful surgical procedures that you can have. Cataract procedures are performed on an outpatient basis and usually only require a few hours of your time from beginning to end.
To begin the procedure, your eye will be treated with an anesthetic so that you will feel little, if any discomfort. A small incision will be made and a microscopic instrument will be passed through it. Using ultrasound from the tip of the microscopic instrument, the ophthalmologist will be able to gently break the cataract into pieces small enough to be washed away, drawn through the instrument and removed from the eye. Once your cataract has been removed, it can now be replaced by a new permanent Intraocular Lens Implant. The new lens is readily inserted and placed in position through the same incision at the outer edge of the cornea through which the cataract was removed.
After the procedure, you will rest for a short time at the clinic before going home. Usually we will arrange a visit to examine your eye within 24 hours after of your procedure. If necessary, your cataract surgeon may prescribe some eye drops for you to use and ask you to wear a protective shield, mainly at night to help you remember not to rub your eye. Although each patient heals a slight bit differently, most patients see well enough to return to their routine activities within a day or so after surgery.
Below, we have detailed the major steps of the cataract procedure. This type of procedure is considered state-of-the-art for cataract surgery today. The procedure demonstrates basic principles only; however, eye surgeons use many variations of the general theme.
Our cataract FAQ may give you more insight.
|Cross-section of the eye:A cataract is a clouding of the lens of your eye that causes blurred or distorted vision. If left untreated it can cause blindness.|
The pupil is dilated and the lens (behind the iris) is now exposed.
A 1.8 – 2.3mm incision is made into the cornea. Due to the small size of the incision, the opening is generally self-sealing.
|Step 2A circular tear is made into the lens. The cataract is now exposed and ready to be removed.|
|Step 3Ultrasonic vibrations are used to break the cataract into smaller fragments that are then aspirated from the eye with a customized suction device.|
|Step 4After the cataract has been removed, a new lens is implanted. In most cases, a foldable lens is placed into an ‘injector’ and inserted through the incision previously made.|
|Step 5As the foldable lens is inserted, it will automatically expand, open up inside the lens capsule, attach and secure itself to the lens wall with specially designed hooks, resulting in……..|
|…….good, clear vision! Depending on the type of intra ocular lens inserted, you might only need a pair of spectacles either for distance or near vision, or no spectacles at all!|
