Early clinical outcomes and comparison between trans-PRK and PRK, regarding refractive outcome, wound healing, pain intensity and visual recovery time in a real?world setup

Abstract Purpose To compare early clinical outcomes of single-step transepithelial photorefractive keratectomy (tPRK) and (PRK) regarding refractive outcome, visual acuity, wound healing, pain intensity recovery time.d. Methods In this prospective observational study 200 eyes 100 consecutive patients with mild to moderate myopia or without astigmatism were included. One hundred each either treated StreamLight™ tPRK PRK the WaveLight® EX500 excimer laser. Visual acuity (Decimal) was assessed preoperatively at day 4, 7 6 weeks postoperatively. Wound healing (hours between surgery complete epithelial closure) monitored slit lamp. At subjectively rated maximum within last 4 days using a numerical rating scale (0–15). Results significantly faster in group. 7, mean monocular UCDVA better group than ( p < 0.001). Four after 72 % but no eye had 0.7 better. six postoperatively, 1.0 achieved both groups. Complete closure 0.0001) level first lower 0.0001). No patient lost line BCDVA complications adverse effects observed. Conclusions According our results, treatments options appear be safe effective methods for correction low astigmatism. However, study, offered associated less compared PRK. It can therefore considered good treatment option who refuse are not eligible Femto-LASIK, same time demand more comfortable offer.
