Choose the type of laser vision correction surgery
There are three main categories of laser vision correction surgery, PRK, LASIK and LASEK. How should we choose it?
PRK is a relatively early technology of laser
vision correction surgery, it is obsolete. Although the PRK can achieve the
appropriate effect, but the pain of postoperative is obvious. And a few
cases can have corneal opacity problem. Thus, while the price of the PRK
laser eye surgery is relatively low, patients should not try to select it.
LASIK is the mainstream surgery of laser vision correction now, it is
safe and effectiveness.
-
IntraLASIK is a variation of LASIK using the IntraLase®
FS femtosecond laser instead of a microkeratome blade to cut the corneal flap.
Custom Lasik (Wavefront-guided Lasik) can guides the laser.
The custom Lasik surgery uses 3-dimensional measurements of how your eye
processes images to guide the laser in re-shaping the front part of the cornea.
Wavefront-optimized Lasik, It is a standard Lasik procedure
performed using Wavelight's Allegretto Wave Eye-Q laser, which is four times
faster than conventional excimer lasers. Wavefront-optimized Lasik contain
both Conventional Lasik and Custom Wavefront-Gudede Lasik, it aims to
correct refractive errors while maintaining the natural shape of the cornea
to prevent inducing higher-order aberrations during the vision correction process.
LASEK eye surgery is an update of a PRK surgery. It
is a complement for peoples who are not a good candidates of Lasik eye surgery.
LASEK eye surgery will still has the risk of corneal opacity and it is also
generally more painful than a LASIK procedure and the discomfort may last for a
week or so.
