목적: 원시에서 굴절교정레이저각막절제술(photorefractive keratectomy, PRK)과 라식수술을 비교 분석하였다. 대상과 방법: +6.00 D 이내 원시, 난시 ‐2.00 D 이내인 환자들 중, PRK수술을 시행받은 38안(21명)과 라식수술을 시행받은 41안(25명)을 대상으로 술 후 시력, 굴절력, 안정성, 효율성 및 예측성을 비교 분석하였다. 결과: 평균 구면렌즈 대응치는 술 후 1개월, 3개월에 PRK군과 라식군 사이에 통계적으로 유의한 차이가 있었으나(p<0.05), 술 후 6, 12개월에는 유의한 차이는 없었다(p>0.05). 나안시력은 술 후 1개월째 PRK군과 라식군 사이에 통계적으로 유의한 차이가 있었으나(p<0.05), 술 후 3, 6, 12개월에는 유의한 차이는 없었다(p>0.05). 최대교정시력은 술 후 1, 3, 6, 12개월에 두 군에서 통계적으로 유의한 차이는 없었다. 안정성은 술 후 1, 3, 6, 12개월에 두 군에서 통계적으로 유의한 차이는 없었다(p>0.05). 효율성은 술 후 1개월째 PRK군이 라식군보다 통계적으로 유의하게 낮았으나(p<0.05), 술 후 3, 6, 12개월에 통계적으로 유의한 차이는 없었다(p>0.05). 술 후 1년째 예측성은 두 군 사이에 통계적으로 유의한 차이는 없었다(p>0.05). 결론: PRK수술에서 술 후 1개월째 라식수술에 비해 근시 양상을 보였으나, 술 후 3개월 이후에는 두 수술 간의 차이가 없었다. 원시환자에서 PRK수술과 라식수술의 효율성과 안정성은 술 후 3개월 이후 차이가 없는 것으로 판단된다.
Abstract
Purpose: We compared the results of photorefractive keratectomy (PRK) and laser in situ keratomileusis (LASIK) for the correction of hyperopia. Methods: Patients who underwent PRK or LASIK, under +6.00 diopters (D) hyperopia and under ‐2.00 D astigmatism were included. In total, 21 patients (38 eyes) underwent PRK surgery and 25 patients (41 eyes) underwent LASIK surgery. We compared the visual acuity, refractive error, safety, and efficacy between the two groups. Results: The manifest refractive spherical equivalent (MRSE) of the PRK and LASIK groups at 1 and 3 months after surgery was significantly different between the two groups (p < 0.05). However, the MRSE was not significantly different at postoperative 6 and 12 months between the two groups. The uncorrected visual acuity (UCVA) of the PRK and LASIK groups at 1 month after surgery was significantly different between the two groups (p < 0.05). However, the UCVA was not significantly different at postoperative 3, 6, and 12 months between the two groups. The best‐corrected visual acuity was not significantly different at postoperative 1, 3, 6, and 12 months between the two groups. The safety index was not significantly different between the two groups at postoperative 1, 3, 6, and 12 months. The efficacy index of the PRK group was lower than that of the LASIK group at 1 month after surgery. However, the efficacy index was not significantly different at postoperative 3, 6, and 12 months between the two groups. There was no statistically significant difference between the predictability of the two groups at postoperative 1 year. Conclusions: After PRK treatment, temporary myopic deviation was observed after 1 month, but there was no significant difference between the two treatments after 3 months of follow‐up. In the correction of hyperopia, there was no significant difference between PRK and LASIK in efficacy or safety.
