Cataract

What is a Cataract?

A cataract is a clouding of the normally clear lens of the eye. It can be compared to a window that is frosted or “fogged” with steam.


Symptoms

  • Painless cloudy, blurry vision
  • Difficulty reading small print
  • More difficulty seeing at night or in low light
  • Sensitivity to light and glare
  • Change in colour perception
  • Frequent changes in eyeglass or contact lens prescription

Who Is at Risk for Cataracts?

Cataracts develop as part of the aging process, so everyone is at risk eventually. By age 75 about 70?% of people will have cataracts. With age, our eyes lens slowly becomes less flexible, less transparent and thicker. Then areas of the lens become cloudy as protein in the lens begins to clump together.

These factors increase your risk of developing cataracts:

  • Advanced age;
  • Diabetes;
  • A family history of cataracts;
  • Extensive exposure to sunlight;
  • Smoking;
  • Previous eye injury or inflammation (swelling) in the eye;
  • Previous eye surgery;
  • Long-term use of steroid medication (especially combined use of oral and inhaled steroids).

 

When to consider surgery

Surgery is offered when the cataract becomes visually significant to the patient and the patient feels that the quality of the vision is impacting on their day to day life. If the cataract is not affecting the patients quality of life, then it will be monitored on a six monthly basis and assessed accordingly by Mr. Golchin.

How is the cataract removed?

The surgery is performed as a day case procedure.

The cataract is removed by a surgical technique called phacoemulsification. The cataract is replaced with a permanent artificial lens implant. This surgery is carried out through a very small incision which reduces the healing time and speeds up the visual rehabilitation of the eye.

This is carried out under topical anaesthesia (needle free) i.e. anaesthetic drops with no injections; this avoids a local anaesthetic injection, which can be painful, and a source of stress for patients. Topical anaesthesia is free from side effects associated with other forms of local anaesthesia and has the added advantage of no disruption to the patients’ anticoagulation treatment (there is no need to stop Aspirin or Warfarin). General anaesthetic is also available when indicated or preferred by the patient. Surgery is very quick (15-20 minutes) and painless for the patient.

The patient is discharged once fully recovered.

Risks and complications

Cataract surgery is considered is regarded as a very safe procedure and major sight threatening complications are very infrequent. However, as with any surgical procedure, there are risks associated with cataract surgery which can include:

  • Infection
  • Bleeding inside the eye
  • Increased pressure inside the eye (Glaucoma)
  • Swelling of the retina
  • Swelling of the cornea
  • Retinal detachment
  • Loss of vision (partially or completely)

In some cases, the part of the lens covering that supports the IOL (called the capsule) can become cloudy several months or years after the first cataract was removed. This is called an "after cataract" or "secondary cataract." If this occurs and blurs your vision, Mr. Golchin will make an opening in the centre of the cloudy capsule with a laser to allow light to pass through the lens properly again. This procedure called a posterior capsulotomy, takes about five minutes and requires no recovery period.

Most people who wear bifocals or reading glasses for near vision may still need to wear glasses after cataract surgery for reading and in some cases even for distance. Best vision is usually achieved once both eyes have been operated on.


Following Discharge

Diet

  • Normal diet.

Medications

  • Please instill the post operative eye drops as instructed. Resume normal medicines.

Activity Guidelines

  • Wear the eye shield supplied for one week after the surgery at night to avoid rubbing the eye while you sleep.
  • Do not swim for at least 2 weeks.
  • Avoid vigorous exercise for at least 2 weeks.

Follow-up

The first morning after your surgery you will be seen in the Outpatients Department where your shield will be removed, your eye cleaned and drops instilled.

Please bring all your drops with you to the clinic on the day of your follow up appointment.

Allow 1-2 minutes between both sets of drops.  Use your drops as prescribed.  You will be given a review appointment for follow up

VIEW ALLWhat Our Patients Say

After visiting my G.P regarding my failing eyesight, I was diagnosed with cataracts in both eyes. I was sent for a consultation with Mr Golchin. Mr Golchin met me in late January 2012. He planned for removal of the cataracts with the procedure to be scheduled during the following two months. As I was extremely nervous. I requested that the procedure be carried out under full anaesthetic. The first procedure, for removal of the cataracts was carried out on 27th February, 2012, followed by the second and final procedure being carried out on 30th March, 2012. My vision now. at 20/20, is better than it has been in many years. I have returned to driving and take the simple things, which were once almost impossible, in my stride. My Entire experience with Mr Golchin was very satisfactory and I highly recommend him to anyone contemplating eye surgery.
