What are Cataracts?

Cataracts are very common. They cloud the lens of the eye, affecting vision, and are usually a consequence of ageing. Sometimes a cataract may form in younger patients as a result of trauma, intraocular surgery, repeated ocular inflammation, high myopia, diabetes, etc. Cataracts can also be congenital. All cataracts require treatment if they affect vision.

Types of Cataracts

  • Nucleosclerotic cataract
  • Cortical cataract
  • Posterior sub-capsular cataract

Causes of Cataracts

The number one cause for cataract is ageing. The degree does depend on genetics and why the patient has a cataract.

There are other causes – things like having diabetes accelerate your process of cataract formation. Sometimes a cataract may form in younger patients as a result of trauma, intraocular surgery, steroid medicines, repeated ocular inflammation, high myopia, diabetes, etc.

Some unfortunate children have cataracts that they are born with and they cause similar problems as the cataracts in the elderly population. There are rarer causes associated with systemic diseases that your doctor will probably advise you on.

Private Cataract Surgery

Because cataracts are so common, the NHS has trouble keeping up with demand which means that many patients have to wait many months to get their cataracts treated. Some people might not be eligible to have cataract surgery through the NHS, as the cataract is not bad enough on the reading chart in the clinic, but bad enough to have influence in day to day life. For those people private cataract surgery is a solution.

Another benefit of private cataract surgery is, that you can choose the best surgeon for you with the best technology.  If you have private medical insurance, or wish to pay to get your cataracts removed, you can elect to go privately with Clinica London.

Examination for Cataracts

The nurse will measure your vision

The nurse first measures your vision for both near and distance with your best glasses on. We then dilate your pupils with eye drops to make the eye examination easier. The drops take about 15 to 20 minutes to work and may blur your vision for several hours afterwards. You should not drive or operate machinery until the effects have worn off.

The cataract surgeon will examine your eyes


Ophthalmologist | Medical Retina | Cataract Surgeon


Ophthalmologist | Glaucoma Specialist | Cataract Surgeon

One of the Ophthalmic Consultants, Mr Jaheed Khan or Laura Crawley, examines your eyes using the slit-lamp. This is to determine the type of cataract, measure the eye pressure and look at the retina and especially the macula. If required, special retinal tests and photos are done. Once the diagnosis of cataract is made and you decide on surgery, the ophthalmic consultant will discuss with you the options for local anaesthesia, the type of intraocular lens to be used and whether you want to wear glasses afterwards, for reading, distance or not at all.

The nurse will measure your eyes for the Intra-Ocular Lens

Biometry is done to measure the eye for a customized intraocular lens as once the cataract is removed, the eye will need a new lens. Each lens has a specific power, which is individual to each patient.

a) Mono-focal Lens
The large majority of patients opt for an intraocular lens that is set for distance vision. This is called a mono-focal lens. With this lens type, you will still need to wear reading glasses for close-up tasks.

b) Multi-focal Lens.
Some patients are very keen to be completely free of glasses after their cataract operation. We can offer a multifocal intraocular lens that is set for all distances (reading, intermediate and distance). This should be discussed with your surgeon to see whether it is suitable for you.

c) Toric lens
Some patients have an irregular corneal shape known as astigmatism. We can offer an intraocular lens that can correct for this, known as a toric intraocular lens implant.

More about the different types of Cataracts

Nucleosclerotic cataract

This is the most common type of cataract and causes blurred vision, increased short-sightedness, dulling of colours and light.
The central part of the lens becomes denser and yellow, the eye more myopic and images dulled.

Cortical cataract

This is a quite common type of cataract where there are radial opaque spokes which can cause glare, distorted, ghosting and double vision and blurring.

Posterior sub-capsular cataract

Posterior sub-capsular cataract which causes glare and worse vision in bright lights when the pupil constricts.
