경도 및 중등도 근시환자에서 PRK 후 교정법에 따른 인공수정체 도수 비교 = Comparison of IOL powers by corrected method in eyes after PRK in mild to moderate myopia

다국어 초록 (Multilingual Abstract)

To compare IOL powers which are calculated by post-op keratometric(K) values and refraction derived K values, and by refraction corrected method, respectively, in patients who have been treated with excimer laser photorefractive keratectomy(PRK) for mild to moderate myopia.
A total of 38 consecutive eyes of 23 patients who were treated with PRK for mild to moderate myopia have been followed up for more than 6 months. IOL powers from SRK/T formula by post-op K values and refraction derived K values were compared with IOL powers by refraction corrected method.
The mean values of IOL powers using post-op K values, refraction derived K values, and refraction corrected method were 20.69±0.93(18.21 to 22.93) diopter(D), 20.81±0.88 D(18.60 to 22.43), and 21.26±0.79 D(19.08 to 23.03) respectively. There was no significant statistical difference between the mean values of IOL powers using post-op K values and refration derived K values (p〉0.05). However, the mean value of IOL powers by refraction corrected method was statistically higher than other two values(p〈0.05).
In patients with excimer laser PRK treatment for mild to moderate myopia, IOL power using refraction corrected method was statistically higher than IOL power using post-operative K values and refraction derived K values.
