Cataract Surgery

A cataract is a clouding of the natural lens that is contained in the eye. Symptoms of cataract include blurred vision, increased sensitivity to light, double vision arising from the affected eye, and poor colour vision.

When a cataract is removed the natural lens is removed and replaced by a clear implant lens. The procedure is painless and takes about ten minutes. Local anaesthetic drops are used to numb the eye prior to the procedure. Usually the vision is improved by the next day, and continues to improve for at least several days.

In skilled hands modern cataract surgery is very safe, but as with all surgical procedures there are risks. These will be discussed by your consultant at your consultation.

Cataract surgery gives the opportunity to correct short sight, long sight and astigmatism. This is because the implant lens is tailored to the shape and size of the patient’s eye. 

An increasingly popular option is to use a trifocal lens implant that gives better vision for reading and other close work without glasses. These lenses have the ability to focus for both near and far, in contrast to standard lenses that only have distance focus. Most people are suitable for a trifocal lens, but there are some circumstances where it is not advisable. This will be discussed by your consultant. In some circumstances an extended depth of focus lens is recommended, which also gives a good range of focus, although not quite as close as a trifocal.

Many eyes have a non-spherical shape, causing astigmatism. This can usually be satisfactorily corrected with a toric lens implant, available in monofocal, trifocal and extended depth of focus formats.
