Abstract
Purpose: To analyse the addition power of new wearer of progressive addition lenses. Methods: Data of 636 subjects who have been prescribed progressive addition lenses as the first time were used for analyse. The range of age for was between 41~78 years old and they visited the optical practice in Gwangju metropolitan city from 2001 to 2013Date of refractive state, gender and age were analysed. Results: The difference of addition by gender was 1.71 D in male and 1.67 D in women. The difference of addition by refractive error was 1.67 D in emmetropic patients and 1.74 D in myopic patients, 1.90 D in hyperopic patients. The difference of addition by age was1.26 D in 41~44 years old sge group, 1.48 D in 45~49 years old age group,1.72 D in 50~54 years old age group 1.84 D in 55~59 years old age group, 2.10 D in 60~64 years old age group and 2.43 D in over 65 years old age group. The difference of addition by diopter in myopic patients was 1.58 D in low myopic patients and 1.48 D in middle myopic patients, 1.67 D in high myopic patients. The difference of addition by axis of astigmatism was 1.80 D in with-the-rule astigmatism, 1.64 D in against-the-rule astigmatism and 1.65 D in oblique astigmatism. Conclusions: The Addition power of progressive lenses were different according to the types of refractive error, astigmatism axis and age.
목적: 본 연구에서는 누진렌즈 안경 처음 착용자의 가입도를 비교 분석하였다. 방법: 2001년부터 2013년까지 광주광역시 소재의 안경원을 방문한 41~78세의 노안인 사람 중에 안질환이 없고 누진렌즈 안경을 처음 처방받은 636명을 대상으로 굴절상태와, 성별, 연령대에 따른 가입도를 각각 분석하였다. 결과: 성별에 따른 가입도 차이는 남성이 1.71 D, 여성이 1.67 D로 나타났고, 굴절이상에 따른 가입도는 정시안이 1.67 D, 근시안이 1.74 D, 원시안이 1.90D로 나타났으며 연령대에 따른 가입도는 41~44세는 1.26 D, 45~49세는 1.48 D, 50~54세는 1.72 D, 55~59세는 1.84D, 60~64세는 2.10 D, 65세 이상은 2.43 D로 나타났다. 근시안의 분류에 저도근시는 1.58 D, 중등도근시는 1.48 D, 고도근시는 1.67 D로 나타났고 난시안의 분류에는 직난시는 1.80 D, 도난시는 1.64 D, 사난시는 1.65 D이었다. 결론: 누진렌즈의 가입도는 굴절이상과 난시의 종류, 연령에 따라 차이가 있었다.
