Cataract
Any clouding in the natural lens of the eye is called a cataract. There are various causes for this and the effect on vision will vary. If the eyesight is sufficiently impaired, surgery to remove the cataract can be offered.
Cataract removed
The cataract is removed, leaving the empty lens capsule in place ready to receive the lens implant.
Lens implant
Once the cataract has been removed, an artificial lens implant can be placed inside the eye.
Various lens options are available to correct short and long-sightedness and astigmatism. Some lens designs offer improved intermediate and near vision as well as distance vision.
Posterior capsule opacification
Sometimes after cataract surgery the capsule which supports the lens implant can become thickened or cloudy. This can cause blurring or misty vision and usually takes several years to develop.
If this is sufficient to interfere with clear vision it can be treated with a simple laser procedure (capsulotomy).
Laser capsulotomy
Laser treatment for capsule opacification creates a small opening in the capsule behind the lens implant so that clear vision is restored.
This is a very safe procedure with rapid improvement in sight.
There may be some floaters for a short time after the laser treatment but this soon clears.
