Trans-PRK smart surFace
The abbreviation Trans-PRK means Trans-epithelial PhotoRefractive Keratectomy. Corneal epithelium and diopter correction occur in the first part of the procedure, when the surgeon uses a high precision excimer laser. In the past PRK was the standard laser treatment for eyes, which was replaced by the LASIK method because it was less painful. However, the LASIK technique disappointed patients who had thick or irregular corneas. The modern approach of Trans-PRK contributed to the optimizing of the procedure in the most important point. This relates almost exclusively to patients who are near sighted or have astigmatism. If hyperopia occurs, the treatment method of Trans-PRK may be performed successfully only when the diopter number is low.
The course of the operation
Patients should not fear this type of operation. Of course, that is easier said than done. Ultimately this is a safe eye procedure. Trans-PRK is a touchless method.
It is hard to imagine a more developed technology than the newest Trans-PRK, which took the place of the classical operation, in this case the conventional PRK, where the surgeon had to cut the flap by hand. Since the excimer laser can perform this step much better, pain is practically absent. Besides that, the healing of the flap is much quicker. In general, the regeneration of the flap does not take longer than three days.
When it is restored, the vision improvement immediately begins- also with the help of the laser. During the fashioning of the upper layer of the cornea comes the removal of the vision defect. For the purpose of protecting the cornea, lessening the pain and accelerating the healing of the eye, doctors will place on the eyes special contact lenses for several days. They will encourage a faster regeneration of the cornea and provide protection
What do you gain thanks to the Trans-PRK smart surFace?
- quicker return to good vision immediately after the procedure compared to other accepted methods, like PRK, LASIK, or EBK
- quicker healing of the corneal flap
- the corneal flap is much smoother
The decisive factor to qualify for the Trans-PRK smart surFace treatment method is a stable vision deficiency for at least twelve months prior to the operation. An indispensable condition is also generally healthy eyes. Conditions like cataracts or a diseased retina will not allow the Trans-PRK treatment method.
In the case of the Trans-PRK surFace treatment method, the value of plus 3 diopters maximum (if you have hyperopia) and minus 6 diopters (if you are nearsighted). Astigmatism may be treated by the Trans-PRK method up to 3 diopters. Only the doctor can determine which method is best for the patient. He knows the patient, and more importantly knows the eye which needs the treatment. Related to that, the method of choice is not always made related to the number of diopters.
In order for the vision to regenerate, often many weeks are required. On a few occasions, patients complain that the healing process is sometimes a little painful, and some experience a sense of blurriness.
