Abstract
To evaluate the usage of plasma rich in growth factor (PRGF) in transepithelial photorefractive keratectomy (TPRK) in low and moderate myopia, patients who underwent myopic and
astigmatism TPRK with PRGF were involved in this retrospective, observational study. Subjects
underwent a surgical procedure between February 2019 and June 2019. A three-month follow-up
was recorded. Pain score was assessed with a visual analogue scale (0–10) and re-epithelialization
time recorded. A total of 48 eyes from 24 patients were recruited. Mean uncorrected distance visual
acuity (UDVA) was 20/20.31 (0.00 ± 0.02 LogMAR). A total of 98% of eyes did not change corrected
distance visual acuity (CDVA) lines. Two percent of eyes lost one line of CDVA. Preoperative spherical equivalent was −2.67 ± 1.37 D and after three months changed to −0.21 ± 0.34 D, and 2% of
eyes changed 0.50 D or more between one and three months. Pain score was 3.29 ± 0.61 (3 to 6)
score points at day one and 0.08 ± 0.27 score points at day seven. Finally, re-epithelialization time
was 2.50 ± 1.20 days. PRGF addition to conventional refractive treatment such as TPRK seems to
alleviate immediate postoperative pain and positively contribute to corneal re-epithelization time.
