Refractive surgery refers to laser vision correction on the cornea, Intraocular lens implant (add-on lens), and lens replacement surgery or refractive lens exchange (RLE).
The cornea is the transparent window at the front of the eye. The laser vision correction works by reshaping the cornea to correct the prescription.
If the cornea is deemed unsuitable for laser vision correction, the next option is to have a lens implant inserted into the eye. These are called Phakic intraocular lens implants, which are essentially an additional lens put inside the eye.
We implant these lenses behind the pupil, just in front of the natural lens. This new lens can focus the image nicely on the retina correcting the vision. It can correct short-sightedness and astigmatism, and in some cases, long-sightedness.
If the natural lens is not that clear after the age of 45, you may be suitable for lens replacement surgery. This is the same as cataract surgery. What we do here is to replace the natural lens with a new implant.
If you want to reduce or eliminate your dependence on glasses for reading and distance, we can implant a multifocal lens.
Multifocal implants have multiple zones that enable you to do varies tasks at different distances. Some of the zones are for reading, some are for intermediate tasks, and some are for distance vision.
