In LASIK therapy a surface with a thickness of 110-160 microns is removed from the external tissue of the eye, or the cornea. By removing this superficial layer, the physician will be able to treat eye disorders by accessing the underlying cornea.
In the Femtolasik method, about 110-120 microns of corneal surface thickness are separated by a laser as a flap. Then, using a laser beam, corneal ablation is performed to correct the refractive errors of the eye.
One of the advantages of the LASIK and Femtolasik methods is that the initial tissue repair is quicker in both ways and the person will be able to return to his daily activities after a short period of time. However, the overall repair process performed at the cellular surface of the cornea is the same in all methods. Considering this point, it is also necessary that the outcome of the surgery, as well as the complications of both LASIK and Femtolasik methods, are similar.
One of the advanced techniques of refractive surgery is the TransPRK technique, which can greatly improve the patient’s vision and allow the patient to use glasses. This laser eye surgery technique is also suitable for people with low or moderate myopia, a Hyperopia or astigmatism. Also, if the patient has a thin cornea, this technique can still be used to treat refractive errors.
In the TransPRK technique, the removal of the outer surface of the cornea and the main treatment of the eye with the laser are performed in only one step. As a result, the treatment time is shortened and the risk of drying the cornea and excessive correction of the cornea is reduced.
The modified TransPRK method, or the Refined TransPRK method, is the latest surgical technique to correct the refractive errors of the eye using laser, which was first invented in Iran by Dr. Adib Moghaddam. Based on the latest research and scientific findings in the Refined TransPRK method, for treating each patient based on its demographic characteristics (such as age and gender) and the optic characteristics of the patient’s eyes (such as refractive errors, refractive errors, corneal thickness, and other cases) Treatment is designed for each patient.
The design of treatments is such that, based on the specific characteristics of each patient, various surgical procedures are corrected. As a result of this specific process for each patient, the conditions of the operation are fully consistent with the patient’s condition, which makes the quality and vision of the patient post-operative significantly higher than other methods.
In the LASIK operation, due to the removal of part of the patient’s corneal thickness and repositioning it, the possibility of weakening of the cornea is due to the fact that the isolated layer does not fully adhere to the cornea and may lead to complications such as eczema or cornea, dryness of the cornea, Flap complications are removed. In some cases, after seeing aura, the patient’s illuminated aura has also been reported. But in the Refined TransPRK method, the overall repair and improvement of the corneal epithelium is faster than the LASIK method. With regard to the results observed in patients undergoing Refined TransPRK, it can be said that the Refined TransPRK method has the best results in patients’ quality and visibility. In this way, the likelihood of returning eye damage has dropped dramatically.
