Ventura PRK: Frequently Asked Questions
There are certain times when Lasik is not a good solution for eye issues. Sometimes, a more suitable approach would be PRK. PRK is a procedure, which was developed around the midpart of the 1980’s. This procedure is packed with a lot of benefits, price ranges, as well as risks – just like other laser eye procedures or surgeries.
PRK or PhotoRefractive Kerectomy is still one of the most common eye surgeries today. This is especially true for individuals who have irregular or thin corneas as well as those who have extra conditions that decrease their candidacy levels for other kinds of vision corrective procedures.
How does PhotoRefractive Kerectomy work?
PRK is considered as an ablative procedure. This simply means that the operating surgeon will remove tissue from your eye. Though Lasik is also considered an ablative procedure, it also an incisional procedure since it involves cutting of tissue. On the other hand, PRK only involves removing.
The basic steps of PRK include:
- Removal of the cornea’s outer layer known as epithelial layer
This is okay as the epithelial layers can still grow back.
- Reshaping of the middle layer of the cornea, the stroma, with the use of laser
This step will help in correcting your vision.
What are the benefits from undergoing a Ventura PRK procedure?
There are certain benefits that a Ventura PRK procedure offers that other eye procedures such as Lasik, do not provide. One of the major benefits would be the avoidance of flap complications, mainly because no flap is created in the first place. In addition, the PRK procedure puts the operated eye in a more stable as well as stronger condition compared to other eye procedures like AK or RK. Lastly, this is also the best solution for individuals who are not fit to undergo Lasik surgeries. This also includes individuals who have irregular or thin corneas and those who do not wish to have any flaps created.
Are there any drawbacks?
Some of the drawbacks of PRK primarily lie on the visual recovery. Compared to Lasik, PRK has slower visual recovery progress. At times, PRK may take weeks for full recovery to ensue while Lasik would only take days. During the first few days of recovery post a PRK procedure, patients may tend to feel different levels of discomfort such as watery and burning eyes. There may also be fluctuating vision due to the re-growing of the epithelial tissue.
What results should you expect from undergoing PRK?
PRK, just like other procedures, also have their own risks. However, the results from PRK surgery may vary from patient to patient. Most patients who underwent PRK for laser vision correction report to have achieved a 20/20 vision while there are a few who do not. Studies have also yielded that both Lasik and PRK can display similar results.
If you are still at a lost on whether you should go for a PRK or Lasik procedure, it would be best suggested for you to inquire from your eye doctor first. Your eye doctor can examine your eyes and evaluate which of the two procedures you can benefit more from.
