No, myopia will not come back after a TransPRK treatment.
After TransPRK, your cornea is reshaped by a laser called the Excimer laser to change the way light bends into your eye, enabling you to see clearly again.
Here's how the laser works:
The laser goes on the treated zone to reshape the cornea curvature to correct the refractive power in one step seamlessly.
This effect is permanent! You can be rest assured that your myopia will not come back again.
Getting blurry vision years after undergoing a laser vision correction procedure is a result of mild myopia regression, and not the original myopia returning. Mild myopia regression that is often caused by long hours spent in front of the computer screen or prolonged near vision work.
Thus, it is always important to adopt good eye care habits such as the 20-20-20 rule: every 20 minutes of near vision work, look at objects 20 feet away for 20 seconds!
Other ways to reduce eye strain include maintaining a comfortable distance between your eyes and reading materials, working in well-lit areas, having a good sitting posture, and eating healthy.
If the myopia regression is less than 0.50 dioptre or 50 degrees, it is best to leave it alonel. If more than that, one can consider the option of enhancement laser vision correction if the cornea is thick enough.
Less commonly, blurry vision years after laser vision correction may be due to development of an eye disease such as cataract, cornea keratectasia (a pathological thinning condition of the cornea) or retinal problems.
