Whether TransPRK, or any other refractive surgery like LASIK or PRK is worthwhile, is a very individual decision. There is generally speaking, no right or wrong answer.
This applies whether we are referring to low or high myopia, astigmatism, hyperopia, or any combination of the above.
The alternatives to improve vision with low myopia are glasses and contact lenses. Each option has its pros and cons. If for example, you would like good vision while remaining spectacle and contact lens free while swimming/hiking/camping etc, then refractive surgery of any kind including TransPRK can be very helpful. If on the other hand you don't mind glasses, and would rather not bear the very small risk of surgical complications, then wearing glasses would be perfectly fine.
