How does PRK differ from LASIK
During LASIK, the first step is the creation of a thin flap of corneal tissue with a femtosecond laser in the modern blade-free LASIK. That flap is then carefully folded back so that the excimer laser can reshape the central layer of the cornea, known as the stroma, correcting the patient’s refractive error. The flap is then folded back into place. PRK is similar to LASIK in that an excimer laser is used to reshape the stroma. The primary difference between LASIK and PRK is that in PRK, there is no flap created.
Who is Eligible?
The ideal candidate for wavefront or topography-guided LASIK has had a stable refractive prescription for at least a year and is ready to eliminate their dependency on glasses and/or contacts. Factors that can affect candidacy are the degree of the refractive error as well as the thickness and shape of the cornea.
LASIK may not be right for you if you have the following:
- Thin corneas
- Large pupils
- Corneal scarring
- Pregnancy or nursing
- An eye condition such as cataracts, glaucoma, or diabetic retinopathy
- A medical condition such as uncontrolled diabetes or a condition that compromises the immune system It is important to discuss your medical history and concerns during your free consultation. Our experienced surgeons will be able to recommend a procedure that meets your vision correction needs.
