How safe is TransPRK?
Very safe. Anyone who undergoes this procedure need not have any concerns.
The epithelium grows back so quickly that hardly any complications can arise. This also means that the eyesight improves within a very short time. Significantly faster than with conventional PRK or LASEK (toxic alcohol effect). However, it takes a few weeks for the eyesight to recover.
In a few cases, treated patients complain that the healing process is sometimes a little painful.
In some patients, there is also a delicate corneal clouding or scarring (haze). This causes a mostly temporary deterioration in vision. Eye drops help here in the short term, and this clouding, also known as haze, is also not permanent.
Patients need to follow all recommended post operative check-ups.
How safe is PRK?
The superficial cells are removed here with the help of a mechanical instrument. First, however, the cells are soaked in alcohol, which also has a toxic effect. This is also the reason for the prolonged wound healing compared to the Trans-PRK. The epithelium grows back together within 3-7 days. This also means that the ability to see increases within one week, although somewhat more slowly than with Trans-PRK. Nevertheless, it takes a few weeks for the vision to recover.
In a few cases, patients complain that the healing sometimes hurts a little due to the effect of alcohol. Some patients also experience a slight corneal clouding/scarring (haze). This usually causes a temporary deterioration of vision. Eye drops help in the short term, and this clouding, also known as haze, is not permanent.
All patients need to attend follow-up appointments after the operation.
How safe is LASEK?
With LASEK, the surgeon removes the superficial cells with the help of a mechanical instrument. The removed epithelial surface is often larger than the required “laser zone diameter”. This causes prolonged wound healing compared to Trans-PRK. The epithelium grows back together within 3-7 days, and the vision returns within one week. This recovery is slower than with Trans-PRK, where we remove only the most necessary epithelial area with the laser. Nevertheless, it takes a few weeks for the vision to recover.
In a few cases, treated patients complain that the healing sometimes hurts a little. In some patients, there is also a slight corneal clouding/scarring (haze). This usually causes a temporary deterioration of vision. Eye drops help in the short term, and this clouding, also known as haze, is not permanent either. All patients need to attend the follow-up appointments after the operation.
