A basic error related to laser eye surgery entails confusion between LASEK and LASIK procedures. To begin, the two treatment sounds the same and are both usually used to correct the same issues with eyesight- namely, farsightedness, nearsightedness, astigmatism, and presbyopia. Moreover, the same lasers are utilized for both eye operations and the same amount of time is needed to complete either process. So what’s the difference between the two treatments, and how can you be sure you are choosing the right one?
LASIK and LASEK are similar in various ways. However, they also differ in specific ways, ultimately making patients and their optical surgeons to seriously take various situations before selecting a procedure.
Level of Vision Correction-
The biggest difference in lasek vs lasik has to do with the level of vision correction every procedure provides. Usually, LASIK is suggested for lower levels of correction, while LASEK is suggested for high correction requirements. What’s more, LASIK needs specific thickness of corneal tissue to get a painless procedure and for fast recovery, while LASEK is more suitable for thin or flat corneas.
Another difference is linked with the actual procedure. While both types of surgeries utilize the same lasers, LASIK cuts the stroma and epithelium to a greater thickness- 100-180- which is why the corneal tissue requires to be thicker. During LASEK, the epithelium is cut to a thickness of 50 microns, while the stroma remains uncut. Plus, it uses a trephine, which is a sharp blade that used in other procedures.
LASIK entails less discomfort than LASEK-
Another difference between the two procedures is that LASIK gives less discomfort than LASEK with virtually no pain- and 20/20 vision can easily be achieved. However, there are no complications of stomal flaps with LASEK, and such patients generally experience less dry eye.
While it is wise to do some research and know about the facts behind the LASEK and LASIK surgery before choosing either procedure, the best advice you can get from a laser eye surgeon specializing in both procedures. An optical surgeon can set suitable tests and recommend a laser procedure according to your unique circumstances- making sure you get the treatment that’s perfect for you.
