LASIK en PRK is albei tipes laservisiekorreksie. Beide prosedures verander die kornea om dit minder reflektief te maak, maar hulle doen dit op verskillende maniere.
- LASIK-chirurgie is meer algemeen en beter vir mense om vinniger duidelike visie te kry.
- PRK is 'n beter keuse vir mense wat nie in aanmerking kom vir LASIK nie, as gevolg van droë oë of baie dun korneas, byvoorbeeld.
- PRK, egter, laat nie 'n flap in jou kornea nie. Terloops, dit word algemeen beskou as veiliger en doeltreffender vir 'n leeftyd onder die meeste omstandighede. Oogbesering kan die flap wat agterbly tydens 'n LASIK-operasie vererger en kan komplikasies in die lyn veroorsaak.
- PRK-chirurgie is aansienlik goedkoper omdat die bykomende stap van flapskepping nie daar is nie.

LASIK is die mees algemene vorm van laservisiekorreksie en is al vir meer as gebruik 15 jaar. Met LASIK, a surgeon will perform an incision in your eye to remove the front layer of tissue and reshape it to correct your vision. The laser then creates a flap in the back of your eye that is sewn shut after healing from its surgery.
In kontras, PRK uses a higher-power beam of light to reshape the cornea without making an incision in the eye. Daarbenewens, PRK has fewer side effects than LASIK, which makes it a good option if you experience any discomfort after LASIK surgery or are allergic to some types of lasers (such as epi-LASIK).
What are the differences between LASIK and PRK?
The difference between LASIK and PRK is that LASIK uses a laser, while PRK uses a power tool (microkeratome) to create the flap.
LASIK can be done by an ophthalmologist or a surgeon, whereas PRK requires a cornea specialist. In both cases, the procedure takes about 10 minute, but in LASIK, it takes about 15 sekondes.
PRK is only available for patients who have very thin corneas — those with more than 0.25mm of corneal thickness — and those who have astigmatism.
LASIK, or laser-assisted in situ keratomileuses, is a medical procedure that uses an eye surgeon’s laser to reshape your corneas. PRK, of fotorefraktiewe keratektomie, is a similar procedure where the surgeon reshapes your corneas with an excimer laser.
The main difference between LASIK and PRK is that LASIK does not use an excimer laser and instead uses a lower-energy gas laser to reshape the cornea.
The main difference between LASIK and PRK is that LASIK uses an excimer laser (also called an excimer laser) to reshape your cornea instead of using a pulsed dye laser (PDL). The excimer laser has a shorter wavelength than PDL, which means it will cause less damage to tissue as it heats up tissue near the surface of your cornea.
This allows the shape of your cornea to be changed more precisely without causing as much damage to nearby tissue as other types of lasers.
Which one is better for me, LASIK or PRK?
so, which is better, LASIK vs PRK?
In LASIK surgery, the surgeon uses a femtosecond laser to heat the front surface of your cornea (epithelium).
This causes tiny damage to the epithelium so that it can be replaced by collagen. When this happens, you won’t see any signs of injury on your cornea because new collagen will grow and form a tight seal over the damaged area.
In PRK surgery, your surgeon uses an excimer laser (an ultra-short wavelength) to cut out layers of tissue from your eyes and then replace them with new collagen. This gives you immediate vision improvement without any pain!
PRK is a type of laser eye surgery that uses a very high-powered beam to reshape the cornea and correct refractive errors. It’s the most commonly performed LASIK procedure, but it can be quite expensive and is only recommended for people with very good vision.
LASIK is more complex than PRK but also more effective at correcting nearsightedness and farsightedness. The laser technology used in LASIK is similar to that used in PRK, so your surgeon can combine both procedures into one if needed.
What about ICL?
ICL, or Implantable Collamer Lens, is an artificial lens that the doctor permanently embeds inside the eye. It can treat nearsightedness and farsightedness but generally carries a higher infection risk than LASIK, as entry to the internal eye is required for this placement.
in ICL surgery, 'n lens word tussen jou natuurlike lens en die iris ingesit. 'n Klein insnyding word gemaak om dit te doen. Dit word oor die algemeen aanbeveel vir mense wat ouer word 21 om 45 wat nie in aanmerking kom vir LASIK of PRK nie.
Final verdict
Oor die algemeen, LASIK is 'n meer gewilde keuse omdat daar minder ongemak betrokke is, en die pasiënt kry merkwaardig vinniger duidelike visie in vergelyking met 'n PRK-operasie. PRK, egter, het sy eie stel voordele en is die eerste oogrefraktiewe oogchirurgie waartoe mense toegang gehad het.
Albei het hul eie voor- en nadele, and you should consult with a professional before making up your mind. In terms of cost, PRK costs less than LASIK. Both are permanent and solve the problems of nearsightedness, versiendheid, and astigmatism. The best way to determine which one is right for you is to consult.
In kontras, ICL is another option for people who are ineligible for LASIK or PRK for any reason.
