RLE (refractive lens exchange) is the most suitable surgical option for age-related vision loss. It is also an option for severe myopia, severe hyperopia and severe astigmatism.
RLE is similar to modern cataract surgery, where the natural lens is replaced with a permanent intraocular lens.
RLE is often recommended for patients over the age of 50 years, as the natural eye lens begins to become dysfunctional causing presbyopia.
There are three types of intraocular lenses available:
- Monofocal or single focus lenses which focus at either near, intermediate or far distance
- Multifocal lenses which focus at both near and far distance
- Extended Depth of Focus lenses which focus at all distances.
Both eyes cannot be treated with RLE at the same time but they may be treated one to two weeks apart.
Vision correction with RLE is achieved immediately, recovery takes just days and optimal vision is usually achieved within four to six weeks.
