CATARACT SURGERY

The purpose of your lens is to bend (refract) light rays that come into the eye to help you see. Your own lens should be clear, but with a cataract it is cloudy. Having a cataract can be like looking through a foggy or dusty car windshield. Things may look blurry, hazy or less colorful.

The only way to remove a cataract is with surgery. Your ophthalmologist will recommend removing a cataract when it keeps you from doing things you want or need to do.

During cataract surgery, your cloudy natural lens is removed and replaced with a clear artificial lens. That lens is called an intraocular lens (IOL). Your ophthalmologist will talk with you about IOLs and how they work.

Before surgery:

Your surgeon will measure your eye to determine the proper focusing power for your IOL. Also, you will be asked about any medicines you take. You might be asked not to take some of these medicines before surgery.

You may be prescribed eye-drop medicines to start before surgery. These medicines help prevent infection and reduce swelling during and after surgery.

Your ophthalmologist may ask you not to eat any solid food at least 6 hours before your surgery.

Cataract removal surgery may be done in an outpatient surgery center or in a hospital. Here is what will happen:

  • Your eye will be numbed with eye drops or with an injection around the eye. You may also be given a medicine to help you relax.
  • You will be awake during surgery. You may see light and movement during the procedure, but you will not see what the doctor is doing to your eye.
  • Your surgeon looks through a special microscope. She creates tiny incisions (cuts, created by blade or a laser ) near the edge of your cornea. The surgeon uses these incisions to reach the lens in your eye. Using very small instruments, he or she will break up the lens with the cataract and remove it. Then she puts your new lens into place.
  • Usually your surgeon will not need to stitch the incisions closed. These “self sealing” incisions will close by themselves over time. A shield will be placed over your eye to protect it while you heal from surgery.
  • You will rest in a recovery area for about 15–30 minutes. Then you will be ready to go home.
  • You may have to use eye drops after surgery. Be sure to follow your doctor’s directions for using these drops.
  • Avoid getting soap or water directly in the eye.
  • Do not rub or press on your eye. Your ophthalmologist may ask you to wear eyeglasses or a shield to protect your eye.
  • You will need to wear a protective eye shield when you sleep.
  • Your ophthalmologist will talk with you about how active you can be soon after surgery. He or she will tell you when you can safely exercise, drive or do other activities again.

Like any surgery, cataract surgery carries risks of problems or complications. Here are some of those risks:

  • Eye infection
  • Bleeding in the eye
  • Ongoing swelling of the front of the eye or inside of the eye
  • Swelling of the retina (the nerve layer at the back of your eye)
  • Detached retina (when the retina lifts up from the back of the eye)
  • Damage to other parts of your eye
  • Pain that does not get better with over-the-counter medicine
  • Blurred vision
  • Seeing halos, glare, and dark shadows
  • Vision loss
  • The IOL implant may become dislocated, moving out of position

Cataract surgery will not restore vision lost from other eye conditions such as macular degeneration, glaucoma, or diabetic retinopathy. Your ophthalmologist will talk with you about the risks and benefits of cataract surgery.

Your vision could become cloudy or blurry weeks, months or years after cataract surgery. This is not unusual. Your doctor might call this a “posterior capsular opacification (or PCO).” It's also called "secondary cataract" or "scar tissue." It's not like a scar you get on your skin. But because it happens after the eye has healed from cataract surgery, some people think of it as a scar. It happens when a membrane called the posterior capsule becomes cloudy. It might help to think of the posterior capsule as a transparent pocket. It holds your IOL in place. It also once held your eye’s natural lens (what became the cataract) in place. If you notice cloudy vision again, you might need to have a laser procedure. The laser creates an opening in the cloudy capsule and is called a posterior capsulotomy (or a YAG laser capsulotomy). This procedure helps restore clear vision.

Pre surgery Instruction

Drops and treatment:
  • Inform the doctor (ophthalmology and anesthesia) about the medications the patient takes, especially blood coagulation drugs, and ask if I need to stop them.
  • Drop an antibiotic (Vigamox, Zymar, or Oftox):
    An antibiotic drop continues to be used every 6 hours that begins a day or two before the operation and continues for two weeks after the procedure.
  • A drop of inflammation to relieve pain and is free from Acular or Acuvail
    Use the drop 24 hours or 48 hours before the procedure as directed by the doctor and every 6 hours (4 times) per day for a week.
  • Start using a drop (Cortisone, Pred Forte)
    For a period of at least 4 weeks, they start gradually 4 times a day for a week and are reduced weekly until they are once in the last week
  • Return and continue to all the medications that the patient is used to, such as diabetes, pressure, and others

  • Note: Drops are separated for at least 5 minutes.
    Follow this procedure after surgery:

    Cataract is a simple surgery that takes 10-20 minutes The patient returns to the house immediately after the operation, where the patient is given (Diamox) pills to reduce the possibility of high intraocular pressure, which may accompany the operation sometimes, especially those who have intraocular pressure (blue water) previously.

    Cataract Water Surgery Tips:
  • Do not perform any strenuous activity for several weeks and avoid heavy exercise. It is possible to do walking and simple sports
  • Do not drive until the doctor tells you when to start driving and work during the first days
  • Dont rubbing the eye
  • Wear a plastic eye guard when sleeping and during the day or a 5-day protective sunglasses
    Follow your doctor's instructions regarding eye drops, antibiotics, and anti-inflammatory drugs.

    If you have difficulty taking medications, you can seek help from your family or a friend

  • Stay away from the places where it exceeds dust, dust or other things, which raises the eye because your eyes will be sensitive that travel in the air like dust
  • Do not rub your eyes because this movement may develop and cause an infection and you have not recovered from surgery
  • It is best to avoid swimming in the pool A week after the operation or wear ( Goggles ) special glasses
  • For women, do not use cosmetics at least two weeks after the procedure
  • Before you leave, eye drops and other medications will be dispensed to prevent infection and reduce inflammation
  • You will need a family member or friend to take you home
  • When you get home, you should take a rest and sleep after several hours
  • After performing the operation. It is possible to watch the TV or the computer for a short period of time. There may be fluctuations in vision from (4-1) weeks.

The vision will be blurry and this is normal because of your surgery, so your eyes need rest and healing, and the harsh the white water, the slower the improvement in the vision and then the vision will be clearer.


    Several days after the operation:
  • If you encounter any of the following symptoms, you should go to the center
  • Vision loss
  • Intolerance to lighting
  • Feeling intense pain with your use of medicines and antibiotics
  • Nausea and vomiting
