What it is
A phakic intraocular lens (IOL) is an artificial lens implanted inside the eye without removing your natural lens — “phakic” means the natural lens stays in place. It works like a permanent contact lens placed inside the eye, usually just behind the iris (the coloured part of the eye). It can correct high short-sight and astigmatism.
Who it's for
Adults with stable glasses power, often high power, or whose corneas are too thin for laser vision correction. Measurements of the eye, including the space inside the front of the eye, decide whether a phakic IOL is suitable.
What to expect
A detailed pre-operative evaluation includes a full refraction and assessment of how stable your prescription is, measurement of the anterior chamber depth and other internal eye dimensions, a corneal endothelial cell count, eye pressure measurement, assessment of corneal shape and health, and an examination of the natural lens and retina. The lens is then inserted through a small incision under local anaesthesia — usually anaesthetic eye drops — and positioned inside the eye, usually in front of the natural lens, which is left in place. The procedure is normally done as day surgery, one eye at a time, and you go home the same day with someone to accompany you.
Recovery
Mild discomfort, watering, light sensitivity or temporary blurred vision can occur in the first day or two, and vision often improves soon after surgery, though recovery varies from person to person. Use the prescribed eye drops, avoid rubbing or pressing on your eyes, and follow your doctor's advice about physical activity and water exposure. Attend all scheduled follow-up visits, which check eye pressure, lens position, corneal health and overall recovery.
Frequently asked questions
Can a phakic IOL be removed?
Yes. If needed, the lens can be removed or exchanged, as decided by your surgeon.
Will I feel the lens in my eye?
The lens sits inside the eye, so once the eye has healed it is not normally felt.
