Vision after surgery is not as expected
One of the risks of lens replacement surgery is that in some cases there may be some residual short or long-sightedness, or astigmatism following the procedure. 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 lens replacement treatment. These visual side-effects reduce significantly in the first month and continue to resolve over a three 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.
In less than 0.05% of cases, lens surgery complications in the form of severe infection may occur despite the use of antibiotic eye drops. It is therefore extremely important to report any sudden loss of vision or pain immediately to Optegra.
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 lens replacement 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.
