Purpose
To compare the clinical outcome of transepithelial photorefractive keratectomy (tPRK) and traditional PRK
techniques.
Setting
Vanak Ophthalmology Clinic, Tehran, Iran.
Methods
This randomized clinical trial included 120 eyes from 60 consecutive patients with moderate myopia referred to our clinic, in year 2020. Patients were randomly assigned to be operated either using tPRK method (using Wong baker scale) or traditional PRK method.
Results
The mean UCVA improvement was significantly higher in tPRK group (p = 0.031), but this difference was not statistically significant regarding the BCVA improvement. The mean Spherical Equivalent change in the PRK group in the one-month follow-up was 3.68 ± 1.00 and in the tPRK group it was 4.12 ± 0.92, indicating a better improvement in the tPRK group (p = 0.012). The mean haze in patients undergoing tPRK was significantly lower than the PRK group one moth postoperatively (p < 0.001). Also the patients undergoing tPRK experienced significantly less pain (p = 0.027) and discomfort (p < 0.001) compared to the PRK group. There was no difference between the two groups regarding intraocular pressure after surgery.
Conclusions
The results of our study showed the superiority of the tPRK method over the PRK in some parameters when
correcting moderate myopia.
