What Is Cataract ?

  • The lens of your eye is normally clear, allowing light to pass through. The lens helps focus the light on your retina (the light-sensitive layer of tissue in the back of your eye) so you can see things clearly, whether they’re up close or far away.
  • Your lens is mostly made of water and proteins. Normally, the proteins line up in a special way so that your lens is completely clear and light can pass through easily. If the proteins in your lens clump together, the lens gets cloudy and can affect the sharpness of your vision. This cloudiness is known as Cataract.
  • Cataract keep you away from seeing clearly because light can’t pass through the clumps of proteins in your lens very easily. Overtime, the clumps of protein get bigger and thicker, making it harder for you to see. The lens may also develop a yellow or brown tint, which can change how you see colours. Mostly it is caused by ageing process.

Causes For Cataract

  • Natural ageing process
  • Diabetes- Among diabetics, cataracts appear early & grow faster who have fluctuating sugar
  • Intake of steroids
  • Excessive intake of alcohol
  • Exposure to cancer radiation therapy and ionizing radiation
  • Excessive sunlight exposure
  • Having family history of early cataracts
  • Hypertension
  • Overweight/Obesity
  • Recent eye surgery
  • Congenital cataract due to intrauterine infection or may be genetic

Symptoms

Cataracts develop slowly and painlessly over time – in fact, in early stages, symptoms may be so mild that you may not even realize your vision is changing. However, as cataracts become denser, you will experience one or more of the following:

  • Glare while driving
  • Double Vision (Diplopia)
  • Halos around lights
  • Frequent change in glasses
  • Fading in colors

Visual Acuity
  • A visual acuity test measures your quality of vision at certain distances. Your healthcare provider will ask you to read letters of various sizes from a chart. Your eyes will be tested individually and together. This helps to measure the accuracy of your eyesight at different distances.
  • The results of this test are recorded as a ratio, such as 20/20 or 20/40. 20/20 vision is considered normal. The ratio of 20/20 means you can see an object that's 20 feet away as clearly as anyone else with normal vision. If you have 20/40 vision, you can see an object that's 20 feet away as clearly as someone with normal vision can see an object that's 40 feet away.4
  • A visual acuity test is an easy, painless, and quick way to evaluate your vision. More tests will be needed, however, to determine if cataracts are the cause of your vision problems.
Contrast Sensitivity
  • Contrast sensitivity testing is similar to visual acuity testing. The goal of this test is to find out how easy it is for you to separate an object from its background. If it's hard for you to identify an object when it's on a low-contrast background, then you have poor contrast sensitivity.
  • Cataracts can decrease image contrast. This happens because the cataract can cause light scattering and glare.5
Slit Lamp
  • A slit lamp is a special type of microscope that magnifies your eye. This lets your healthcare provider see the cataract and determine how severe it is.
  • During this test, you will place your chin on the chin rest of the slit lamp. Your healthcare provider will direct light at your eye and look through the slit lamp.
Pupil Dilation
  • Pupil dilation is a common test used to diagnose cataracts. When your eye is dilated, the pupil increases in size. This makes it possible for your healthcare provider to see your entire lens. A good view of the whole lens lets your healthcare provider determine if a cataract is affecting your quality of vision.6
Potential Acuity Test
  • A potential acuity test measures how well the eye would see without the cataract. It is typically done before cataract surgery to confirm that the procedure will improve your vision.
  • During this test, a device called a potential acuity meter (PAM) projects an eye chart onto the eye with a laser. The projection bypasses the cataract.7 The patient reads the chart just like a normal eye chart on a wall.
  • If the best measurement is 20/40, the eye will have at least 20/40 vision after the surgery. This test becomes more important when the patient also has another eye disease as well as a cataract.

Principles of Cataract Surgery
  • In cataract surgery a small ultrasonic probe is inserted through a tiny incision on the edge of the eye. This probe gently breaks the cloudy lens into tiny pieces and sucks the cataract out of the eye.
  • The traditional phaco surgery uses more energy while removing cataract like jackhammer. Because of heat produced during the procedure, large numbers of endothelial cells of an eye are destroyed contrary to newer procedures.
Treatment

Surgery is the only treatment of cataracts. Cataract surgery is considered to be one of the safest and most successful procedures performed in medicines today. The surgery involves creating a microscopic incision through which the cataract is removed and a replacement man-made intraocular lens (IOL) is implanted. This small incision seals itself naturally and allows for rapid healing.

  • Proven Patented Ozil® Technology
  • Capability of performing Micro incision Phaco
  • Most widely used Phaco system in the world
The Benefits
  • 10 minutes painless procedure, no stitch, no injections and no patch surgery
  • Customized to your individual eyes and needs
  • Enjoy crystal clear vision with lifestyle IOLs
  • Less energy utilized during cataract surgery
  • Precise, accurate incisions and treatment
  • Resume daily activities like cooking, watching TV, taking bath etc. within a few hours of surgery.

Lenses

Monofocal
  • These lenses can restore clear vision for one area of focus only, usually distance vision. You will still need to use glasses for near activities such as reading, sewing, writing and using the mobile
Multifocal
  • These lenses restore vision for near as well as distance and greatly reduce the dependency on glasses after surgery. Some patients may require glasses for intermediate use such as while using a computer. Sometimes, optics is associated with glare and haloes in night time.
Trifocal
  • These lenses are advancement over standard multifocal lenses which provide near, intermediate as well as distance vision and are hardly associated with glare or color halos
Toric IOL
  • Astigmatism is the cylindrical component of the shape and number of the eye. If you are planning a cataract surgery and have high astigmatism, you may be required to correct this in addition to the conventional spherical power intraocular lens, to ensure better clarity post-surgery. These lenses are called TORIC LENSES. They are available in Monofocal and Multifocal varieties. If the cylindrical power is left uncorrected, the person may require glasses to improve clarity in vision even after removal of cataract.
Aspheric IOL
  • match more closely the shape and optical quality of the eye's natural lens, and thereby can provide sharper vision — especially in low light conditions and for people with large pupils. Popular aspheric IOLs that are FDA-approved and available in the U.S. include: Tecnis (Johnson & Johnson Vision), AcrySof IQ (Alcon), and enVista (Bausch + Lomb).
    Better contrast with Aspheric IOLs than spherical IOLs
Spherical IOL
  • A spherical intraocular lens can induce minor optical imperfections called higher-order aberrations (HOAs), which can affect quality of vision, particularly in low-light conditions such as driving at night.

Frequently Asked Questions

Wear sunglasses: Ultraviolet light from sun may contribute to the development of cataracts. Wear sunglasses that block UVA and UVB when you are outdoors. Ask our experts for UV protection glasses and wear hats

Quit smoking

Avoid excessive alcohol consumption

Manage other health problems. Follow your treatment plan if you have diabetes or other medical conditions that can increase your risk of cataracts.

Eat a healthy diet – Eating healthy & blocking UV together can delay ageing by 15 years!!! . Adding a variety of colorful fruits and vegetables to your diet ensures that you're getting vitamins like C and E and other antioxidants.

Get regular eye exams

After a thorough check-up, if you are diagnosed as having a cataract, you will be advised by your doctor about the cataract removal procedure which involves removal of the clouded cataractous lens using the appropriate technique and replacing it with an artificial clear Intra Ocular Lens (IOL). The surgery takes few minutes and the patient is discharged the very same day.

Laser treatment may be recommended for people with diabetic macular edema (DME). The goal of this treatment is to prevent further vision loss. The laser seals leaking blood vessels, reduces swelling and prevents new abnormal blood vessels from growing. For macular edema, the laser is focused on parts of the retina outside of the macula. Multiple laser treatments may be necessary. Laser treatment is not a curative procedure and does not always prevent further loss of vision.
