PRK vs. LASIK
Both PRK eye surgery and LASIK eye surgery are used to treat myopia, hyperopia, and astigmatism. Both the LASIK and PRK procedures work by using a laser to reshape the eye's corneal tissue and correct vision. However, the procedures are performed differently and have distinct advantages and disadvantages.
PRK Surgery
During PRK eye surgery, the surgeon accesses the cornea's inner layers by removing the thin outer layer of the cornea, the epithelium, altogether. After the PRK procedure, bandage contact lenses are worn to promote healing of the epithelium.
LASIK Surgery
During LASIK eye surgery, however, the surgeon uses a microkeratome blade or a laser to create a corneal flap. This flap of tissue is then folded back, exposing the inner cornea where the treatment will take place. Afterwards, the flap is repositioned and will naturally heal on its own, without use of special contact lenses.
PRK and LASIK Surgery Results
Both LASIK and PRK produce similar vision correction results, but it typically takes longer to fully recover from PRK. LASIK patients typically experience clearer vision within hours of undergoing the procedure, while PRK patients generally experience better vision a few days after undergoing treatment. The main advantage of the PRK procedure, however, is that patients who are not good candidates for LASIK due to certain corneal conditions or corneal scars can often be effectively treated with PRK eye surgery. If you are interested in laser vision correction, a specialist can explain PRK vs. LASIK in more detail and help you determine if either procedure is right for you.
