PRK eye surgery in Melbourne is a popular refractive treatment that is often used when a patient is ineligible for other types of refractive surgery. PRK surgery in Melbourne, short for photorefractive keratectomy, was first performed in Melbourne in the 1990s. Even with the emergence of newer treatments such as LASIK and SMILE®, it has remained an effective technique for laser vision repair since then. Patients who undergo PRK can acquire clear unassisted vision without the use of glasses or contact lenses.
What is the mechanism behind it?
For many years, this eyesight correction treatment has been conducted successfully. There are various steps to it.
The top layer of the cornea is removed. The surgeon needs access to the cornea’s stromal layer. However, there is another layer (the epithelium) on top of it that needs to be removed. The stroma, which is where the cornea must be reshaped to correct eyesight, is exposed as a result of this.
The stroma is reshaped using an excimer laser to the exact shape necessary for the particular patient. This is one micron, or one thousandth of a millimetre, exact.
Following surgery, the eye is fitted with a bandage contact lens, which will be removed by the surgeon in three to five days once the thin layer of superficial cells has naturally regenerated.
What are some of the advantages of this type of vision correction?
While most people choose LASIK or SMILE because of the speedier and more comfortable recovery, ASLA is frequently advised for those who have corneas that are not suited for the flap required for LASIK. This type of vision correction surgery has advantages, such as a lower risk of ocular dryness (dry eye), which can occur with other methods.
Why does recovery from PRK take so long?
PRK has the disadvantage of taking longer to recover from than LASIK. Patients are given oral and topical pain relief to keep them as comfortable as possible in the days after the operation, which can be difficult. Within a few days, the patients’ vision will be fully functional, and they will be able to resume most of their typical activities within a week.
If you’re considering laser eye surgery but don’t qualify for LASIK, know that the ASLA/PRK technique has been successfully done on thousands of patients in Australia since 1991.
Any queries you may have concerning your laser eye surgery will be answered by your laser eye surgeon.
If you’ve been researching laser eye surgery, you’ve almost certainly come across the word PRK. This was the first laser eye surgery operation before LASIK and SMILE, and it was called photorefractive keratectomy. Dr. Theo Seiler conducted it for the first time in 1987, but it wasn’t commercially available until the 1990s. It’s also known as ASLA (advanced surface laser ablation). Do you also want to get your vision cleared then this is the best option to opt for. You can your vision will get better and you will be able to work in an efficient manner without any stress on your eyes.
