Brief about Cataract

What is Cataract

A cataract is a cloudiness or opacity of the eye’s naturally clear lens. It obstructs the passage of light to the retina of the eye and impairs vision. When the lens develops cloudiness to the point that it impairs vision, it is called Cataract. It is like looking through frosted glass.

Symptoms

  • Progressive and painless blurring of vision is the commonest symptom.
  • The blurring of vision may be more marked in bright light.
  • Brightness and contrast of the image decrease in an early cataract. Some individuals experience glare while driving at night.
  • Colors may become less distinct. Later on, the vision deteriorates and interferes in day-to-day activities.
  • Seeing multiple moons at night also suggests a cataract.
  • Pain, itching, redness, or eye watering are not symptoms of cataracts. Cataract usually develops in both eyes but may progress at different rates.

1. Age-related cataracts: Most cataracts are related to aging.
2. Congenital cataract: Some babies are born with cataracts or develop them in childhood, often in both eyes. These cataracts may not affect vision. If they do, they may need to be removed.
3. Secondary cataracts: Cataracts are more likely to develop in people with specific other health problems, such as diabetes. Also, cataracts are sometimes linked to steroid use.
4. Traumatic cataracts: Cataracts can develop soon after an eye injury, or years later.

Currently, there is no medical treatment to reverse or prevent the development of cataracts. Once they form, there is only one way to achieve clear vision again, and that is to physically remove the cataract from the eye.

It depends on the quality of your vision. If the decrease in vision interferes with your day-to-day social, personal or professional services, you should not wait. With good results, it is not worth just managing with compromised vision.

Yes. Surgery is the only option. Medicines can not cure.

Cataract removal is one of the most common operations performed in the world today. It is also one of the safest and most effective. In about 90 percent of cases, people who have cataract surgery have better vision afterward.

As with any surgery, pain, infection, swelling and bleeding are possible, but very few patients have serious problems or complications. Your surgeon may prescribe medications for these effects. But in case of rare symptoms like excessive pain, vision loss, or nausea, and report these symptoms to your eye surgeon immediately.

MICS( Minimal Incision CatarcatSurgery-Phacoemulsification

It is no stitch small incision cataract surgery. The incision is only 1.8mm – 2.8mm long. Phacoemulsifier is special medical equipment that is used to remove cataracts. The minute (2.6mm or more minor) incision is self-sealed and needs no suture or stitch to close. The patient will return to normal activities within a few days, including attending the office or doing heavy manual work.

There are 3 treatment options available for cataracts:
MICS with Phaco Emulsification with Foldable intraocular Lens Implantation SICS ECCE (conventional method)

I. Micro Incision Phaco Emulsification with Foldable Intraocular Lens Implantation
Cataract extraction by Phaco Emulsification through a 1.8 mm incision and implanting a Foldable intraocular Lens is a definite technological advancement from conventional surgery. The lens is injected into the eye through a small incision and it opens up within the eye like a flower.

Il. SICS (Small Incision Cataract Surgery)

The clouded cataractous lens is extracted by fragmenting it into tiny pieces with ultrasound energy and aspirated out with a suction device. The cataract is removed through a small self-sealing wound. There are no sutures applied to the eye. The patient will need glasses for near vision.

Advantages:

Requires no stitches (Incision 2.8 mm) Is non-invasive and painless Early rehabilitation Less induced astigmatism Perfect early restoration of vision

111 ECCE (conventional method)

Requires an incision of 9 mm surgeon removes the clouded lens in one piece hard rigid lens is implanted, and Multiple stitches are required
Increased risk of post-operative distorted vision and complications
Most patients require glasses for both distance and near vision

Toric IOLs (Intra-Ocular Lenses)

A significant proportion of the population has astigmatism (cylindrical refractive errors) that is not corrected with standard IOLs resulting in the need for spectacles for both distance and near vision. With the availability of cutting-edge technology, it is possible today to implant such people with customized IOLs that have the capability to correct cylindrical errors as well. These IOLs are known as TORIC IOLs and are available in both single focus and multifocal platforms. The use of these IOLs offers greater chances of spectacles-free vision to the patient.

Once a cataract has been removed, it cannot develop again. However, over time, patients may notice that their vision has once again become hazy. This condition, which can occur with any type of IOL, is known as secondary cataract, or posterior capsular opacification (PCO). Secondary cataracts can be easily treated with a simple laser procedure performed in OPD.
