What is refractive lens exchange?
Refractive lens exchange removes a clear natural lens and replaces it with an artificial one, to correct a prescription rather than to treat a cataract. It is the same operation as cataract surgery, performed earlier, and it is usually considered when the lens is no longer able to change focus anyway.

In more detail
Because it is irreversible, the case for it rests on what you gain: a prescription corrected and reading vision addressed with a lens designed for both. The trade-offs are the same ones that come with any multifocal implant, and they should be discussed before booking, not after.
What this answer depends on
- Your age and the state of your reading vision
- Which implant your measurements support
- Whether a laser option would achieve the same with less intervention
