Abstract Details

Purpose:

The prospective single-site study set out to compare the refractive outcomes, the corneal higher-order aberrations, the patient-reported outcomes in terms of early recovery and symptoms between a new trans-epithelial PRK (TE-PRK) on the WaveLight platform called StreamLight and manual PRK.

Setting:

The Wellington Eye Clinic, Dublin, Ireland

Methods:

30 patients were prospectively randomised to one eye TE-PRK and the fellow eye PRK for the treatment of myopia and myopic astigmatism. The refractive target had to be emmetropia in both eyes and the refraction within 1.00D of one another.

Results:

The results have not been completed yet as the study uses 6-month data for the refractive comparison. There is no significant difference regarding refractive outcomes for the 1- and 3-month intervals. The PRO data suggests that patients prefer the TE-PRK approach to manual PRK as they find it easier and less manipulation on the eye. The early recovery data has not been analysed yet and will only be available once all 30 patients have been enrolled.

Conclusions:

TE-PRK (StreamLight on the WaveLight platform) is a safe and effective alternative treatment to manual PRK in patients with myopia and myopic astigmatism. Most patients prefer the TE-PRK approach as they find it more comfortable at the time of surgery than manual PRK.
