What is a refractive lens exchange?
Refractive lens exchange (RLE), also known as a clear lens exchange, is a surgical procedure in which the natural lens of the eye is removed and replaced with an artificial lens implant to correct refractive errors and minimise the use of glasses and contact lenses.
The surgical procedure is very similar to cataract surgery. The difference is that in cataract surgery the lens that is removed is cloudy whereas in RLE, a clear lens is removed.
Refractive lens exchange is used for the correction of refractive errors including short-sightedness, long-sightedness, astigmatism and presbyopia (an age-related loss of the eye’s ability to focus on near objects). By replacing the natural lens of the eye with a new artificial lens, the refractive error is corrected by altering the focus of the eye, thus eliminating the need for glasses or contact lens.
Who is suitable for a refractive lens exchange?
Refractive lens exchange is usually recommended for patients over the age of 45 who want freedom from glasses (including reading glasses) and contact lenses and have refractive errors that are not suitable for other refractive procedures.
If you have a mild cataract, a refractive lens exchange may be preferred instead of waiting for the cataract to be advanced enough to require surgery. A refractive lens exchange is the most common procedure performed for those who do not want to wear reading glasses. A multifocal lens implant or a monofocal lens implant with blended vision is used to give you clear distance and near vision.
At your consultation, the health of your eyes will be fully assessed, and a recommendation will be made, tailored to your specific needs and personal preferences.
How is a refractive lens exchange performed?
Refractive lens exchange is performed as a day procedure similar to cataract surgery. The procedure takes about 20 minutes and is performed under local anaesthetic.
A small opening is made in the periphery of the cornea and an ultrasound probe is used to break up the natural lens which is then removed by suction. The artificial lens is then implanted into the eye and is held in place by the capsule of the natural lens. The incision is self-sealing and does not require any sutures.
How quickly will my vision improve after a refractive lens exchange?
Visual recovery is fast and most patients are able to see very well by the next day. Your vision will continue to improve as the eye heals and settles down over the first few weeks. It is not uncommon for the eye to feel gritty and irritable for a few days after surgery. You will be given antibiotic and anti-inflammatory drops to prevent infection and assist with healing.
