CATARACTS

A cataract is a common ophthalmic condition which causes clouding of the natural lens in the eye. The condition is often inevitable as we age and about 60% of people in their 60s and above experience this complication. It usually develops gradually, clouding the natural lens and making vision get misty. Cataracts are one of the most causes of vision loss worldwide.

The word cataract is derived from a Greek word called Cataracti, and this means waterfall. In an advanced stage, cataract can take the form of a waterfall. Ageing is a factor that influences the development of cataract. Some people may develop it earlier than others, but it is one of the inevitable occurrences in life.

The upside is that cataracts are treatable and advances in technology have made cataract treatment safe, simple, and more effective.

Symptoms Of Cataracts

For the eyes to work properly, the natural lens needs to be clear, so people whose lenses are cloudy do not see properly. Usually, light passes through the lens to the retina at the back of the eye. Then the optic nerves send signals to the brain, which interprets the image as what we see, but in people with cataract, less light passes through the lens to the retina, and this affects vision.

Cataracts usually develop slowly, and it eventually leads to a gradual loss of clear vision. Patients with cataracts typically complain of the following symptoms.

  • Mistiness or cloudiness.
  • Changes in prescription glasses
  • Increased scattering of light which causes dazzling when they expose their eye to bright light
  • A loss or fading colour vibrancy (this usually occur gradually and is not apparent)

Causes Of Cataracts

A common cause of cataract is ageing, but a few other factors like the following could cause cataracts

  • Use of steroids
  • Diabetes
  • Ocular inflammation
  • Previous trauma
  • Genetics- some people have a family history of cataracts and have an increased risk of developing it.
  • UV damage, resulting from direct exposure to sunlight

Treatment Of Cataracts

Cataracts can be treated solely by undergoing surgery to remove the protein covering the natural lens.

Cataract surgery

Cataracts surgery in the UK is prevalent, and thousands of people successfully undergo the surgical procedure yearly. Cataract surgery usually lasts for about 30 minutes, mainly under local anaesthetics.

The surgeon uses an ultrasound probe to gently break up cataracts and remove them from the natural lens, then prepares and inserts a natural lens.

Femtosecond laser cataract surgery

It is a new type of cataract surgery now used by most surgeons to remove cataracts. It involves the use of femtosecond laser technology and ultrasound technology. The surgeon uses the special laser to remove cataracts, and this minimises the need for manual removal of cataracts.

The special laser is called femtosecond laser and the surgeon programmes it to make precise incisions between the lens and cornea, and, then the surgeon uses a sophisticated ultrasound device to remove cataracts.

Risks Of Cataracts Surgery

The risks associated with cataracts surgery are small compared to its benefits. On rare occasions, Posterior Capsule Opacification (PCO) occurs. This complication makes a vision to become cloudy because new membranes form over the new lens. However, the complication can be handled by using a special laser to remove the membrane.

Other possible complications of cataracts surgery include:

  • The detachment of the retina
  • Bleeding or infection
  • Tearing of the capsule bag

Notwithstanding, cataracts surgery is arguably the safest modern surgical procedure. Before your surgery, your surgeon will discuss all the risks with you and discuss how you can avoid them.

Cataract surgery does not take long, and the recovery period is also short. You can get an experienced surgeon at Optimal Vision for your cataract surgery. Call us now on 020 71833622 to book an appointment for your cataracts surgery.
