Cataracts and Intraocular lenses

Clear lens extraction and cataract surgery

Cataract surgery is one of the most commonly performed procedures in the world. It involves removing a lens which has become cloudy and replacing it with a lens matched to your eye. Symptoms of cataracts include, glare, changing spectacle prescription, clouding vision and difficult reading in poor light.


Some patients may not yet have cataracts, but would like to be spectacle independent. In these cases, the clear lens can be replaced with a new lens which corrects refractive error.

Generally the new lens enables people to see well in the distance which requires them to use reading glasses for near work. Many people who are motivated to be spectacle free opt for a multifocal or extended depth of focus (EDOF) lens which improves near vision as well as providing distance vision.

Another excellent option is to leave one eye slightly short sighted in a process called blended vision.

Dr Cunneen offers bilateral simultaneous cataract surgery which reduces downtime and follow-up visits. He will discuss all the options at the time of your consultation.

Phakic Intraocular Lenses – the ICL

Phakic lenses can also be used in younger patients who suffer high levels of short or long sightedness.

While conventional laser has limitations on the levels that can be treated, placing a new lens within the eye can treat a much broader range of prescriptions, from -20 and +10. This procedure keeps the person’s original lens in position and places a thin lens within the eye. People who have previously been told they are unsuitable for laser surgery may benefit from this procedure as it doesn’t affect the thickness of the cornea. In addition, the procedure is reversible. To implant the ICL takes around 20 minutes to perform and the recovery is very rapid.
