PRK OR LASIK?
LASIK and PRK are two types of laser vision correction. Which should you choose?
Custom PRK
Much like Custom LASIK, Custom PRK is significantly better than standard PRK for quality vision after laser vision correction. Custom PRK relies on additional information from corneal mapping to treat a larger surface of the cornea and eliminate more aberrations than using simply your refractive prescription.
Custom PRK (also know as aspheric or wavefront-optimized prk) uses added information to help the laser reshape the cornea in a more sophisticated and efficient manner and with added precision.
Thin corneas, big pupils and patients with jobs or hobbies that may potentially traumatize the LASIK flap will do better with custom PRK. Some people will just choose PRK over LASIK because they don’t like the idea of something cutting their cornea. Though all local vision centres offer custom PRK (at a premium surcharge over standard treatment), BoydVision alone offers custom PRK as its primary treatment at the single, most affordable price in BC or Canada.
Before and after Surgery:
The pre-operative assessment and postoperative care are very similar to Custom LASIK. The primary difference is the unpredictability and slowness of visual recovery, and temporary increased pain for some individuals. As a result the patients are given more analgesia initially and are advised it will take longer for them to resume their regular work schedule afterward.
During the Surgery:
Numbing eyedrops are given at the start, after your lids have been opened with a speculum.Alcohol is used to remove the outer layer of corneal skin (epithelium). The laser is then used to reshape the deeper cornea. There is no pain with this, but there may be an odour similar to "burnt hair". Afterward the cornea is flushed with saline and eyedrops, and bandage contact lenses applied.
others will be advised to have PRK for various reasons.
