What Is the Success Rate of Transprk?

Trans-Epithelial Photorefractive Keratectomy, also known as Trans-Epithelial Photorefractive Keratectomy, is a type of laser eye surgery that has lately grown in popularity due to its minimally invasive design and potential for quicker healing times than other laser eye surgery procedures.


How does TransPRK implement?

The epithelium, or the cornea’s outermost layer, is removed using a laser during a TransPRK treatment. The same laser is used to restructure the underlying corneal tissue after the epithelium has been removed to rectify the refractive defect. Over the following few days, the epithelium naturally regenerates, serving as an all-natural bandage to shield the eye as it heals.

To ensure the patient is comfortable throughout the surgery, the eye is numbed with eye drops before the treatment. During the procedure, the eye is held still by a special device while the cornea is reshaped and the epithelium is removed. Normally, the entire process takes 15 to 30 minutes to complete.


How does TransPRK compare its success rate to other forms of laser eye surgery?

First, it’s critical to comprehend how TransPRK operates. A specialist laser is used during the treatment to reshape the cornea, correcting refractive defects such as astigmatism, nearsightedness, and farsightedness. TransPRK does not call for the formation of a corneal flap, in contrast to other types of laser eye surgery. Instead, the cornea’s outermost layer, known as the epithelium, is removed by the laser before the underlying tissue is modified. Over the following few days, the epithelium regenerates, serving as a natural bandage to guard the eye while it heals.


So what is TransPRK’s success rate?

Studies have shown that TransPRK has a high success rate for correcting refractive defects. In a meta-analysis of 11 studies encompassing 1,172 eyes altogether, the success rate of TransPRK was found to be 93 percent. Achieving postoperative uncorrected visual acuity of 20/20 or greater was the benchmark for this success rate. 

According to a Singaporean study with a mean follow-up of 12 months, 94.3% of patients had postoperative uncorrected visual acuity of 20/20 or greater after TransPRK. A low incidence of sequelae was also noted in the trial; only 3.3% of individuals experienced substantial postoperative haze.

The results of TransPRK and LASIK, another type of laser eye surgery that entails making a corneal flap, were compared in a study carried out in Turkey. The study indicated that both procedures had a similar risk of complications and treated refractive defects in an effective manner. The study did highlight, however, that healing was quicker following TransPRK, with patients reporting less pain and a quicker return to vision.


Points to remember- What Is the Success Rate of Transprk?

Although these studies indicate that TransPRK has a high success rate in correcting refractive defects, it is crucial to remember that individual outcomes may vary based on elements such as the severity of the refractive fault, the thickness and shape of the cornea, and the patient’s general eye health. Like any surgical procedure, TransPRK may have risks and issues. These include dry eye, infection, and corneal haze.

Before undergoing TransPRK, it is essential to examine the pros and cons of the procedure with a qualified eye surgeon. Your surgeon will be able to evaluate your needs and determine whether TransPRK is the best option for you. They can also offer guidance on how to prepare for the procedure and what to expect during the healing process.

A safe and effective refractive error correction technique is TransPRK. The procedure has a high success rate compared to the risk of problems, and patients frequently report a speedier recovery period than with other kinds of laser eye surgery.


Who is a good candidate for TransPRK?

For those who want to fix their refractive errors and have a stable prescription, TransPRK is a fantastic solution. Different types of laser eye surgery may be more advantageous for patients with thin corneas or other corneal defects.

Patients should get a thorough eye exam prior to the treatment to assess their eye health. Enure they are good candidates. The patient’s medical history will also be reviewed, and measures of the cornea’s thickness and shape will be taken during the eye examination.


What are the benefits of TransPRK?

Comparing TransPRK to other laser eye surgery procedures, there are a number of advantages, including:

  1. TransPRK is a less invasive treatment with a lower risk of problems because it doesn’t call for the development of a corneal flap.
  2. When compared to other types of laser eye surgery, TransPRK causes the cornea’s epithelium to regenerate naturally, which speeds up the healing process.
  3. Results that can be predicted easily. TransPRK has a high success rate and is fairly predictable, so patients can anticipate getting the level of vision correction they want.
  4. TransPRK is a safe and efficient alternative for many patients since it carries a lower risk of issues than other types of laser eye surgery. 


What dangers and issues could TransPRK possibly present?

The TransPRK technique has several possible risks and problems, much like any surgical operation. These may consist of:


Dry eye:
Removing the epithelium during the procedure can cause temporary dryness of the eyes, which can be managed with eye drops.


Each surgical operation carries a modest risk of infection. Following the treatment, patients will receive antibiotics to help prevent infection.


Corneal Haze:
Occasionally, individuals may have corneal haze, a corneal clouding that can impair vision. Usually transient, it is treatable with medicine.


Under- or over-correction:
TransPRK has a high degree of predictability. Hence, there is a minor chance of either condition, which can be remedied with subsequent laser eye surgery.



TransPRK is a less invasive variant of laser eye surgery that is both secure and efficient. It has become a well-liked choice for individuals seeking to cure their refractive problems. Primarily, the reasons may be a quick healing period, reliable results, and a low risk of complications. If you consider TransPRK the best course of action, a skilled eye surgeon should be consulted.
