목적: 역기하렌즈 착용 후 안광학 성분들의 변화에 대한 관련성을 알아보고자 한다. 방법: 7세에서 15세 사이의 -1.00D에서 -6.50D 이하, 총 27명(54안)을 대상으로 역기하렌즈 착용 전, 3~6개월, 7~12개월, 13~24개월, 25~36개월 후의 나안시력, 동공직경, 각막두께, 전방깊이, 각막곡률반경, 굴절교정 값의 변화에 대한 통계적 유의성을 검증하고자 하였다. 결과: 역기하렌즈를 착용하기 전의 나안시력은 0.33±0.19, 3~6개월 후에는 0.97±0.14로 0.63±0.22향상되었고, 7~12개월 후에는 0.95±0.17로 0.61±0.23만큼 향상되었으며, 13~24개월 후에는 0.91±0.22로 0.57±0.27만큼 향상되었고, 25~36개월 후에는 시력 0.86±0.27로 0.52±0.32만큼 향상되어 통계적으로 유의한 변화를 보였다(P＜0.05). 굴절교정 값의 변화는 12개월까지는 변화가 없었고, ㅓ 13~24개월은-0.19±0..50D로, 25~36개월은 -0.30±0.62D로 증가해 통계적으로 유의(PV0.05)한 변화를 보였다. 각막곡률반경은 3~6개월은 1.45±0.97mm로, 7~12개월은 1.40±1.12mm로, 13~24개월은 1.26±1.34mm, 25~36개월은 1.08±1.54 mm로 감소하여 통계적으로 유의한 변화를 보였다(P＜0.05). 각막두께는 3~6개월은 2.21±10.70 Чm로, 7~12개월은 1.21±12.42 Чm로 감소했지만 유의하지 않았고. 13~24개월은0.79± 1..17± m로, 25~36개월은 1.93± 13.97 μm증가했지만 유의하지 않았다. 동공크기는 3~6개월은0.18±0.64mm로, 7~12개월은 0.20±0.64 mm, 13~24개월은 0.14±0.53 mm로, 25~36개월은 0.25±0.56mm 감소해 유의한 변화를 보였다(P；＜0.05). 전방깊이는 3~6개월은 0.66±0.08 mm, 7~12개월은0.03±0.99mm 로 유의하게 감소했으며(P＜0.05), 13~24개월은 0.03±0.13mm 감소했지만 통계적으로는유의(P=0.14)하지 않았고, 25~36개월은 0.05±0.14 mm 감소해 통계적으로 유의(P＜0.05)한 변화를 보였다. 결론: 역기하렌즈를 착용하고 36개월 동안 나안시력이 향상되고, 굴절교정 값의 변화는 크지 않았으며, 각막곡률과 동공크기 및 전방깊이 등의 유의한 변화가 관찰되었다.
Purpose : To investigate changes in ocular components after wearing reverse geometry lenses. Method : We aimed to verify the statistical significance of inhibitive effects against the progression of myopia, based on medical records regarding changes in the uncorrected visual acuities, pupil diameters, central corneal thicknesses, anterior chamber depths, vase curves of the average K- readings and corrected visual acuities of a total of twenty-seven (fifty-four eyes) children and teenagers between the ages of seven and fifteen, and of visions between -1.00D and -6.50 D: before wearing reverse geometry lenses, after three to six months of use, at seven to twelve months of use, at thirteen to twenty-four months of use and at twenty-five to thirty-six months of using the lenses. Results: After wearing reverse geometry lenses. The uncorrected visual acuities slowed significant improvement, from 0.33 ±0.19 initially to an increase by 0.33 ±0.19 to 0.97 ±0.14 at three-to-six months to an increase by 0.61 ±0.23 to 0.95 ±0.17 at seven-to-twelve months, to an increase by 0.57 ±0.27 to 0.91 ±0.22 at thirteen-to-twenty-four months, and to an increase by 0.52 ±0.32 to 0.86 ±0.27 at twenty-five-to-thirty-six months of use. Which was 0.33 ±0.19, by 0.63 ±0.22(0.97 ±0.14)at three to six months of use, 0.61 ±0.23 (0.95 ±0.17) at seven to twelve months of use, 0.57 ±0.27 (0.91 ±0.22) at thirteen to twenty-four months of use and 0.52 ±0.32(0.86 ±0.27) at twenty-five to thirty-six months of use. The subjects` average corrected visual acuity remained unchanged through twelve months and then showed statistically significant (P0.05), and they increased by 0.79 ±13.17um and 1.93 ±13.97um at thirteen to twenty-four months and twenty-five to thirty-six months, respectively, but this also failed to show any statistically significant (P=0.30) change. The pupil diameters decreased by 0.18 ±0.64 mm ati three to six months 0.20 ±0.64 mm at seven to twelve months, 0.14 ±0.53 mm at thirteen to twenty-four months and 0.25 ±0.56 mm at twenty-five to thirty-six months, showing significant(P
