초록
목적: 각막굴절교정렌즈를 착용하기 전후의 근시 진행 정도를 비교하고자 하였다. 대상과 방법: 각막굴절교정렌즈 착용 전 최소 6개월 이상 근시로 본원을 내원한 26명 49안을 대상으로 조절마비굴절검사 또는 현성굴절검사, 저간섭성반사계(Lenstar LS900® Haag-Streit AG, Koeniz, Switzerland)를 시행하여, 렌즈 착용 전후의 구면렌즈대응치 및 안축장의 변화를 비교하고, 안축장 증가와 관련된 인자에 대해 분석하였다. 또한 렌즈 착용 전의 근시 진행 정도가 1D/year 미만인 군과 1D/year 이상인 군으로 나누어 렌즈 착용 후 구면렌즈대응치 및 안축장 변화를 비교하였다. 결과: 각막굴절교정렌즈를 착용하기 전 근시 진행 정도는 -1.1D/year에서 렌즈 착용 후 -0.3D/year로 감소하였다(p<0.001). 렌즈 착용 나이가 어릴수록, 렌즈 착용 시 근시가 적을수록, 렌즈 착용 전 근시 진행 정도가 심할수록, 렌즈 착용 전 안축장이 짧을수록 안축장 증가 정도가 컸다(p<0.001, p=0.004, p=0.007, p<0.001). 근시 진행 정도에 따른 비교에서 안축장 증가는 근시 진행 정도가 많은 군이 0.2 mm/year로 근시 진행 정도가 적었던 군의 0.1 mm/year에 비해 의미 있게 큰 결과를 보였다(p=0.001). 결론: 각막굴절교정렌즈의 착용 후 근시 진행 정도는 렌즈 착용 전에 비해 유의하게 감소되었다.
Abstract
Purpose: To compare the myopic progression before and after wearing an orthokeratology lens (OK). Methods: Twenty-six patients (49 eyes) with at least 6 months of myopia prior to OK treatment were evaluated. Changes in the spherical equivalent (SE) refractive error and axial length were compared before and after OK use. Changes in the SE and axial length were also compared between two groups according to the myopic progression before baseline: Group 1 with myopic progression < 1 D/year and Group 2 with myopic progression > 1 D/year. Results: The myopic progression rate decreased from -1.1 to -0.3 D/year after OK treatment (p < 0.001). Greater increases in axial length were observed in patients who were younger and had less myopia at baseline, a higher rate of myopia progression before baseline, and a shorter axial length at baseline (p < 0.001, p < 0.004, p < 0.007, and p < 0.001, respectively). The increase in axial length was significantly greater in the group with greater myopic progression before baseline (0.2 mm/year) than in the group with less myopic progression (0.1 mm/year) (p = 0.001). Conclusions: Myopic progression was reduced significantly after OK treatment.
