What is PreLex?

PreLex (Presbyopic Lens Exchange) is "The removal and replacement of the natural lens of the eye with any degree of cataract where the goal is to provide uncorrected (no glasses) Distance, Intermediate, and Near (reading) vision."

PreLex is best suited to people over the age of 50 who are experiencing the loss of near, reading vision from Presbyopia, but can simultaneously correct distance vision problems that require glasses or contacts such as nearsightedness and astigmatism.

PreLex is predominantly a refractive surgical procedure although most patients having it done also have at least some sign of cataract as well. It is a more invasive than LASIK because it is intraocular surgery, but will typically last longer for the same reason.

Here is an excellent video explanation of PreLex.
