REFRACTIVE LENS EXCHANGE
LASER-FREE VISION CORRECTION
Can you see as well as you did in your twenties, regardless of your age?
There are various ways in which modern technology can liberate people from the need for glasses for distance and for near. Multifocal intraocular lenses (IOLs) provide simultaneous light in focus in each eye from both near objects and distance objects.
These lenses have undergone a process of continual evolution over the last decade. The Mplus multifocal lens from Topcon has taken the lead delivering incredibly consistent visual outcomes for both distance and near vision without glasses.
Accommodating lenses – Crystalens ™
Another option, which can work well, is the use of accommodating lenses, which simulates the lens action, which acts in young eyes. These lenses provide some ability to “pull focus” for near objects. Most people do still require spectacles for reading very fine print, however.
Accommodating lenses are an excellent option for people who do not have such a strong visual system.
Lens exchange blended vision
A final way in which presbyopic lens exchange can be used to restore the level of functional vision which people enjoy in their twenties is with a form of lens exchange blended vision.
Again, it is possible to set one eye with clear vision for distance and the other eye with clear vision for near. Again, this can work extremely well, providing a wide range of visual function and a high level of independence of the need for spectacles.
As ever, it is imperative that the technology is matched to the individual patient’s lifestyle, visual system, and the unique anatomy of their eye.
What refractive lens exchange treats
How does the refractive lens exchange (also known as lens replacement) procedure work?
How do multifocal IOLs work?
Multifocal intraocular lens (IOL) technology has provided great improvements in the quality of life of many patients by providing a range of focus and a very high level of independence from glasses.

Frequently asked questions about refractive lens exchange
The lower age limit for laser eye surgery at Custom Vision Clinics is 21. There is no upper limit for treatment, but lens surgery may be a better option for some people after the age of 50. It is the biological age of the eye rather than the chronological age of the individual which is most important in guiding treatment recommendation. There are some patients in their early sixties who have crystal clear natural lenses with no sign of cataract and these patients may be suitable for Presbyond ™ LASIK laser eye surgery.
Patients having laser eye surgery (LASIK and SMILE) routinely have surgery at the same sitting. This avoids the inconvenience of walking around for a week with one eye treated and the other eye still needing glasses. The risks of laser eye surgery are so small that this is now generally accepted as standard practice in the U.K.
