All About PRK vs LASIK in Michigan
PhotoRefractive Keratectomy (PRK) is a kind of laser-enabled eye surgery. The procedure rectifies a fairly wide range of complications like mild to moderate farsightedness and nearsightedness.
Astigmatism can also be cured through PRK.
When it comes to deciding on PRK vs LASIK in Michigan, it must be noted that both the vision correction procedures use lasers. Both procedures are performed on the cornea. The cornea, covering the pupil, iris and anterior chamber, is a sensitive tissue that allows light to travel through it. The light ultimately reaches the posterior part of the eye.
How do the 2 procedures differ?
The PRK procedure usually begins by the cornea being reshaped, directly on its surface. The difference with LASIK, is that the LASIK laser is performed after a flap is created instead of treating on the surface.
Comparing PRK vs LASIK
In the PRK vs LASIK debate, PRK has a number of undeniable advantages. This procedure is extremely accurate when it comes to correcting nearsightedness issues. About 90 percent of peoplewho have undergone PRK procedures enjoy 20/20 vision within a year after the surgery. No contact lenses or glasses are required post the procedure. About 98 percent of patients enjoy 20/40 or a better vision without being dependent on contact lens or glasses.
There are a few definite disadvantages in PRK surgery when compared to LASIK. These include:
- A sense of mild discomfort. This is inclusive of a little eye irritation and watering of the eye.
- This may persist up to three days after the procedure.
- PRK requires a somewhat longer duration than LASIK to treat the vision. A PRK patient is likely to regain 80 percent of full sight a month after the surgery. Full recuperation percent of the vision may take up to three months. In contrast, LASIK is noticeably faster.
- A few patients may have to continue using glasses even after undergoing the PRK treatment.
Other PRK side effects
A majority of the people who have undergone a PRK operation, have reported an increase in sensitivity towards light. The side effects likely to crop up during the initial six months after the operation include:
- Permanent mild glare in the vision, which the patient may experience for the rest of his/her life.
- Pain in eyes and
- Drying of eyes.
