Abstract：Objective To study the clinical effect of epithelial excimer laser photorefractive keratectomy（TPRK）on high myopia patients with refractive power >-6.00 d. Methods 241 eyes of 181 patients with high myopia with refractive power greater than -6.00D were selected as the research objects.90 patients（118 eyes）in the control group and 91 patients（123 eyes）in the experimental group were randomly divided.Patients in the control group were treated with excimer laser in situ keratomileusis（FS-LASIK）assisted by femtosecond laser flap making.The experimental group was treated with TPRK,and the epithelial healing time was compared between the two groups.The changes of visual acuity（BCVA,corneal posterior surface height,diopter）were compared 3 months after operation.The incidence of surgical complications（infection,corneal penetration,corneal haze under the upper and lower skin）in the two groups were compared within 14 days after operation. Results After operation,the healing time of the epithelium in the experimental group was significantly longer than that in the control group（P<0.05）.Three months after operation,The BCVA and corneal posterior surface height of the two groups were significantly higher than those before treatment,but there was no significant difference between the two groups（P<0.05）.Compared with before treatment,the diopter of patients in both groups decreased significantly,but there was no significant difference between the two groups（P<0.05）.No postoperative complications occurred in the two groups within 14 days after operation. Conclusion The refractive power of TPRK is>-6.00 days after operation,the epithelial healing of the affected eye is slow,the visual recovery effect is excellent,and it has high safety.
