A laser treatment, known as photorefractive keratectomy (PRK), is extensively used to deal with myopia in adults however questions stay over its use in youngsters.

A limitation is that it’s a retrospective study, which means we analyzed information that had been already collected, fairly than organising a brand new trial from the start.

“The analysis means that for well-screened youngsters with steady myopia, PRK may very well be a protected and efficient possibility, particularly when contact lenses or glasses aren’t very best. These findings might assist increasing the standards for providing PRK to chose youngsters. Age alone mustn’t disqualify a motivated and well-suited teenager from having this remedy.”

The researchers will proceed to observe the youngsters who acquired laser remedy to examine for very late issues or adjustments in imaginative and prescient.

Professor Thomas Kohnen is Chair of the ESCRS Publication Committee, Director of the Division of Ophthalmology at Goethe College Frankfurt, Germany, and was not concerned within the analysis.
