Cataracts

Cataracts are very common, and millions of corrective procedures are performed worldwide every year, with excellent results.

Symptoms can include:

cloudy, blurred vision
poor night vision
haloes around lights
yellowing, sepia effect vision, which diminishes colours

What is a Cataract?

A cataract refers to the gradual clouding of the natural crystalline lens within the eye. This lens is part of the eyes overall focusing power so clarity is very important for good vision.

The majority of cataracts develop with time and are age-related. As the lens becomes more opaque, the quality of vision will progressively deteriorate. Cataracts can be caused prematurely by trauma, certain medications or even be apparent from birth.

FAQ

What are the symptoms of a cataract?

Cataract symptoms vary depending on severity and maturity of the cataract. Initially, glasses prescriptions can change more frequently but as cataracts worsen so does the quality of vision, even with glasses. Colours can become less vibrant, increased blurring and, glare and haloes around lights at night.

How are cataracts treated?

A cataract treatment is usually performed as an outpatient procedure using topical anaesthetic.

During surgery, the cloudy, natural lens is removed and replaced with a clear lens implant called an intra-ocular lens (IOL). The whole procedure takes around 10-15 minutes and is a minimally invasive technique.

What vision can I expect after cataract surgery?

All patients should notice relief from their cataract-related symptoms. However, many people are unaware that the vision achieved after surgery depends on the type of intra-ocular lenses (IOL) implanted. It is a great opportunity to treat the cataract and simultaneously free patients from the need for glasses at various distances.

At VCC, we offer three types of lenses, standard, enhanced and premium. Further to a detailed consultation with your surgeon, including a thorough clinical examination and time to find out about an individual’s lifestyle and needs, your options will be explained, and a recommendation will be made by your consultant.

How long does it take to recover?

Most patients experience improved vision within a few days and can typically resume day-to-day activities within a week. Patients preferring enhanced and premium lenses will also experience a period of neural adaption as they get used to their new vision.

Is a cataract treatment permanent?

A cataract procedure is permanent; however, some patients can experience posterior capsular opacification (PCO). This is a condition that is experienced by around 20% of routine, uncomplicated cataract patients. The intra-ocular lens is placed in the eyes’ natural capsule or bag; this can thicken and lose transparency. Some patients describe this as the cataract growing back.

How do you treat posterior capsular opacification?

To clear the vision, a simple procedure called a laser capsulotomy is performed. This is performed in the clinic, sitting facing a machine called a YAG laser. First, the pupil is dilated and then the YAG laser is used to create a hole in the thickened capsule. Sometimes anaesthetic drops and a lens on the front of the eye for stability are used. No further special aftercare is necessary.
