Materials and Methods: Eighteen patients with a decision for treatment due to adenoviral corneal opacity were divided into two groups comprising a total of 23 eyes. Eleven eyes in the first group underwent only PTK, while 12 eyes in the second group underwent combined PTK+PRK treatments. Spherical equivalents (SE), best-corrected visual acuity (BCVA), and wavefront aberration values were compared within and between groups preoperatively and at 12 months postoperatively.

Results: The mean age was 32±17 years in Group 1 and 28±9 in Group 2 (p=0.9). The duration between infection onset and treatment was 13±2 months and 14±5 months, respectively (p=0.75). The ablation depths were 79±28 ? and 90±16 ?, respectively (p=0.16). Significant differences were observed in BCVA values between the groups at both preoperative and postoperative 12 months (p=0.013 and p=0.02). In both groups, there were significant differences in preoperative SE, BCVA, and spherical aberration (SA) values compared to postoperative 12 months (p values for Group 1 and Group 2, respectively: SE, 0.005 and 0.004; BCVA, 0.007 and 0.024; SA, 0.004 and 0.028). However, there was no significant difference in total wavefront aberration and higher-order aberration between preoperative and postoperative values in both groups.

Discussion: Both PTK and PTK+PRK treatments yield successful visual and refractive outcomes in adenoviral corneal opacities. Keywords : Epidemic keratoconjunctivitis, Photorefractive Keratectomy, Phototherapeutic Keratectomy, Subepithelial Infiltrates
