What is refractive lens surgery?

Refractive lens exchange [RLE] has the potential to improve your vision significantly, leaving you with less or even no reliance on glasses and contact lenses. 

The process replaces your eye's clear natural lens with an artificial intraocular lens (IOL) to correct your vision focusing and achieve sharper focus, reducing the need for glasses. The procedure is pretty much identical to cataract surgery. The difference is in the lens being replaced, rather than cloudy due to a cataract.

What are my different RLE options?

Distance vision monofocal lenses

Replacement of the lens in each eye with monofocal lens implants both focused on distance. Potentially a good option for those who require excellent distance vision (driving at night, pilots) and are happy with glasses for near and intermediate vision.

Blended vision

Replacement of the lens in each eye with monofocal lens implants, one eye giving good distance vision and the other better near vision (a little nearsighted). The brain blends the vision from each eye to give an improved range of vision from distance to near, minimising the need for glasses in most day-to-day tasks. Glasses are still likely to be necessary for some tasks (detailed or prolonged near vision, possibly driving at night) and there is often a period of adjustment of a few weeks or more as you get used to the change in vision.

Extended range vision lenses

Replacement of the lens in each eye with a special implant that gives good distance vision as well as an extended range of vision good for intermediate but likely to still require reading glasses for fine near vision tasks.

Trifocal multifocal lenses

Replacement of the lens in each eye with a special implant that gives good distance, intermediate and near vision. You are unlikely to need glasses for any tasks, and is particularly good for those who wish to have good near vision without glasses. There is often a period of adjustment of a few weeks or more as you get used to the change in vision.
