Patients undergoing Clarivu should be aware that no surgical procedure is totally risk free. Your Consultant Ophthalmic Surgeon will discuss any specific risks that you need to be aware of prior to your Clarivu procedure and give you the chance to ask any questions at your consultation.
Vision after surgery is not as expected
In some cases there may be some residual short or long-sightedness, or astigmatism after surgery. Therefore spectacles may be required for specific tasks such as reading small print or driving. In some cases, a laser “top- up” procedure can be carried out to improve the vision further.
Glare & haloes
All patients should be aware that they may experience haloes and glare after treatment. These visual side-effects reduce significantly in the first month and continue to resolve over a 3 month period. Although IOLs may cause some glare, most people adapt over time and do not suffer any long term problems.
Red, sore or irritable eye
Some patients may feel some slight tenderness to the eye area after surgery which will settle down after a few days. The eye can sometimes appear very red due to a blood vessel being disturbed during surgery. This redness dissipates over a few weeks and it does not affect vision or comfort. A gritty sensation can also be felt sometimes, which may be alleviated by dry eye drops. This can take up to 6 to 8 weeks to settle down.
Posterior Capsule Opacification
Over time, in the months and years following surgery, the lens capsule which remains in the eye after surgery to support the IOL can become cloudy. This is treated with the YAG laser which effectively clears away the cloudy parts of the capsule.
After the YAG laser treatment it is common to experience a few or many floaters when looking straight ahead, especially in bright light. These floaters gradually begin to disappear and settle down in the jelly of the eye without causing any problems.
Rare but possible complications
In less than 0.05% of cases, severe infection may occur despite the use of antibiotic eye drops. Any sudden pain or loss in vision must be immediately reported so that Optegra can arrange for swift medical treatment.
The light sensitive membrane at the back of the eye may become detached following surgery. This can be corrected by surgery but there is a risk that the quality of vision may not be the same as before detachment.
Cystoid Macula Oedema
The macula is a part of the retina that provides detailed central vision. Occasionally it can swell after surgery and cause a decrease in vision. Mild cases often resolve with no medical intervention but when detected, it is treated with eye drops. The swelling nearly always responds to treatment.
