History of Trans PRK in Iran

What you must do before and after a Femto-LASIK surgery?

What made us look for a new thechnique?

Photorefractive Keratectomy (PRK) has been one of the most commonly used laser eye surgery technique for the past 20 years. This technique involves the surgeon removing the outermost layer of the cornea (the epithelium) in the area where the underlying cornea is to be treated with a hand-held instrument. The excimer laser is then applied to the cornea to ‘shave’ a minute amount of tissue from the surface.

The technology allows an advanced form of PRK called Transepithelial PRK (T-PRK) to be used. The laser itself removes the epithelium before proceeding to alter the corneal shape.

Why we currently prefer trans-PRK?

Following patient who treated with trans-PRK cleared out that:

  • The results of trans-PRK for myopic (nearsighted) patients are equal to those for LASIK, after one month. The long-term results may even be superior to LASIK.
  • There are fewer dry eyes in comparison to LASIK treatments.
  • There are no flap complications, because there is no corneal flap.
  • The corneal surface needs an average of 2.5 days to heal.
  • After the surface heals, good vision is rapidly restored for myopic patients. Hyperopic patients may need up to 3 months for their vision to improve.
  • Stabilization is often better than hyperopic-LASIK treatments.
  • Using modern bandage contact lenses and topical anesthetics, the discomfort time has been reduced to 24-36 hours.
  • Because we use just one laser in a one-step, no-touch procedure, with very few instruments, the treatment is very cost-efficient.

Trans-PRK is a method with fewer complication possibilities and with long-term results comparable to or even better than LASIK. In our opinion, the good long-term results more than compensate for the short-term disadvantages of trans-PRK.

History of Trans PRK in Iran

In recent years, Dr. Soheil Adib Moghaddam and his colleagues in Iran and Germany have done a very comprehensive study on the clinical outcomes of this surgical procedure. Dr. Soheil Adib Moghaddam in 2010, for the first time in Iran. Now, a new method of Trans PRK surgery has been developed and refined.

The refined TransPRK method is one of newest refractive surgical techniques by laser, which, for the first time in Iran, was used by Dr. Adib Moghaddam. Dr. Adib Moghaddam, considers the features of each patient and individualize the surgical coordination. This leads to a better result of the surgery qualitatively and quantitatively. Refined Trans PRK could improve the stabilization eye vision and success rate of surgery.

Refined Trans PRK Advantages

  • High predictability and efficiency in terms of visual acuity and refraction.
  • Stable refraction achieved by 3rd postoperative month in myopic correction.
  • 1 out of 3 myopic eyes achieve supervision 1 year after operation.
  • Enhance visual quality of patients with various refractive errors.
  • Correct double vision and improve night vision and focousing function.
  • Improve photopic and mesopic CS in myopic correction with or without astigmatism.
  • Promising result in mild-moderate myopic with or without astigmatism.
  • Promising result in hyperopia with or without astigmatism.
  • Efficacy and safety of Refined Trans PRK in asymmetric astigmatism correction.
  • No need for MMC in mild-moderate myopic correction.
