Cataract Surgery Procedure

Cataract surgery (motibindu operation) is done to treat cataract conditions. During this procedure, the damaged, cloudy natural lens is detached and changed with a clear artificial lens. The artificial lens is known as an intraocular lens (IOL). Your ophthalmologist will explain the different IOLs and their benefits to choose one for your eyes.


Types of Intraocular Lenses (IOLs)

Types Purpose Suitable For
Monofocal Lenses These lenses can only restore vision either for short distance or for long distance It is useful for patients with cataract conditions in both the eyes.
Multifocal Lenses They help restore eye vision for both near and far distances and provides multiple point of focus Anyone with vision problem can have these lenses, especially elderly with farsightedness
Toric Lenses They can rectify both spherical and cylinder eye components They are preferred if the patient has a high pre-existing cylinder or astigmatism in their eyes.

Once the lens is selected, the patinet is prepared for the surgery.

Before the procedure -

  • Your eye specialist will recommend urine tests, chest X-rays, and blood tests to check if you have diabetes or other health conditions.
  • You may have to take an electrocardiogram (ECG) test to rule out any heart problems. Inform your ophthalmologist if you have any blood disaeses like haemophilia, thalassemia, etc. Your doctor will ask if you are taking any medications or have allergies.
  • Eye-drop medicines will be prescribed before eye surgery. These eye drops will help prevent eye infections and decrease swelling during and after the surgical procedure.
  • The eye surgeon will measure your affected eye to decide the proper focusing power for your IOL.
  • Your eye surgeon may suggest you to avoid eating solid foods at least 6 hours before the operation.

During the procedure -

Cataract surgery or motibindu operation may be done in a hospital or an outpatient facility.

  • First, the affected eye will be numbed with eye drops or with an anaesthetizing injection around the eye. You may be given a sedative to relax.
  • You will not be completely unconscious during the surgery. You can see the light and the doctors' movements during the operative procedure, but you can't see how the eye operation is done.
    There are four main types of cataract surgery -
    1. 1. Phacoemulsification
    2. 2. Extracapsular cataract surgery
    3. 3. Intracapsular cataract surgery
    4. 4. Laser Cataract Surgery

  1. 1. Phacoemulsification -
    • It is a very common type of cataract operation. The procedure is completed in less than half an hour, with very little use of sedation.
    • In the phaco procedure, the eye surgeon makes a tiny incision around the edge of the cornea to open through the membrane surrounding the natural lens.
    • The surgeon inserts a small ultrasonic probe through this opening to break up the lens into tiny fragments with the help of sound waves.
    • The ultrasonic probe tip contains an attachment that acts as a suction to remove the broken fragments. An intraocular lens implant is then placed in the eye to complete the procedure.

  2. 2. Extracapsular cataract extraction (ECCE) -
    • This kind of cataract surgery is preferred in severe cataract cases that are difficult to treat with phacoemulsification. It involves a larger incision to remove the cataract altogether in one piece, and not in fragments.
    • Once the damaged lens is removed, the intraocular lens is positioned in the lens capsule in the eye. The eye surgeon will then suture the wound and use eye patches to cover it.

  3. 3. Intracapsular cataract surgery: -
    • The surgeon will make a bigger incision in this operative procedure than in the other two eye surgeries.
    • Here is the complete lens and the capsule are detached, and the IOL is positioned in front of the iris.

  4. 4. Laser Cataract Surgery-
    • It is also referred to as Refractive Laser-Assisted Cataract Surgery. The eye surgeon makes an incision in the cornea, followed by an anterior capsulotomy, removing the upper part of the capsule to gain direct access to the cloudy lens.
    • The laser then makes the lens soft to break it into fragments. The intraocular lens is then placed in the eye capsule.

After the Procedure -

  • You will be shifted to a recovery room to monitor your health. As soon as your health is fine, you can go home.
  • Your ophthalmologist will prescribe eye drops for you to use at home. Follow the eye drop instructions properly.
