The Trans-PRK method is the only non-contact laser vision correction technique. The modern capabilities of Trans-PRK have contributed to optimizing the procedure at its most crucial point. However, this applies almost exclusively to patients with myopia or astigmatism. If hyperopia is present, treatment with the Trans-PRK method can only be successfully performed if the number of diopters is relatively low. <\/p>\n\n\n\n

The acronym Trans-PRK stands for Trans-epithelial PhotoRefractive Keratectomy. The corneal epithelium and diopter correction are performed in the first stage of the procedure, with the surgeon utilizing a high-precision excimer laser. PRK was once the standard method for laser eye treatment, but LASIK replaced it due to less associated pain. However, the LASIK technique proved ineffective for patients whose corneas were too thin or irregular. <\/p>\n<\/div><\/div><\/div>\n\n\n\n

Patients do not need to fear this type of surgery. Of course, this is usually easier said than done \u2014 after all, it is a procedure directly on the eye. However, Trans-PRK is a non-contact method. <\/p>\n<\/div><\/div><\/div>\n\n\n\n

It is difficult to imagine a more advanced technology than the latest Trans-PRK, which has eliminated the need for classic surgery, as was the case with conventional PRK where the surgeon had to manually remove the epithelium. Since the excimer laser can perform this much more precisely, pain is virtually non-existent. Furthermore, the epithelial healing process is significantly faster. As a rule, epithelial regeneration does not take longer than three days. <\/p>\n<\/div><\/div><\/div>\n\n\n\n

After the epithelium is removed, the actual correction begins \u2014 also with the use of a laser. By reshaping the upper layer of the cornea, the vision defect is eliminated. To protect the cornea, alleviate pain, and accelerate wound healing, doctors place a special contact lens on it for the first few days. This allows for rapid corneal regeneration and also protects against external influences and stimuli. <\/p>\n<\/div><\/div><\/div>\n<\/div><\/div>\n<\/div>\n<\/div><\/div>\n<\/div>\n<\/div><\/div>\n\n
