최근 1년간 안경 처방을 받은 1,100명을 대상으로 단안난시와 양안난시를 분류하고 대칭난시와 비대칭난시에 관해 조사하였다. 대상자 중 난시가 1,365안으로 59.3%이었고, 단안만 난시인 경우가 235명으로 21.4%, 양안이 난시인 경우가 535명으로 48.6% 이었으며 양안난시가 단안난시보다 2.3배 많았다. 양안난시 535명 중 직난시가 61.2%, 도난시 24.7%, 사난시 14.1% 이었고, 난시도는 -0.25~-0.50D가 47.5%, -0.75~-1.00D가 29.9%로 나타났다. 양안난시 535명 중에서 대칭난시는 446명으로 83.4%(1,100명 기준시 40.5%), 비대칭난시는 89명으로 16.6%(1,100명 기준시 8.1%)으로 대칭난사가 5배 많았다. 연령대별 비율을 보면 41~50세에서 45.4%가 대칭난시이었고 14.3%가 비대칭난시로 다른 연령대보다 높게 조사되었다. 대칭난시를 이루는 좌, 우안의 난시형태는 직난시와 직난시가 65.5%, 도난시와 도난시가 25.3%, 사난시와 사난시가 5.6%였고, 비대칭난시를 이루는 좌, 우안의 난시형태는 직난시와 사난시, 사난시와 직난시가 각각 23.6%, 20.2%로 분석되었다. 결론적으로 안경착용자의 대부분이 난시안을 가졌고 단안난시보다는 양안난시가 많았다. 양안난시에서는 대칭난시가 대부분이었으며 40대의 비율이 높았고 남녀간의 차이는 없었다. 대칭난시에서도 좌, 우안이 직난시와 직난시의 형태가 많은 것으로 조사되었다. 이런 자료를 통하여 난시에 대한 이해의 폭을 넓히고, 보다 편안한 안경 처방의 기본자료로 활용될 것으로 본다.

This study as performed to survey symmetrical and asymmetrical astigmatism among 1,100 patients(2,200eyes) who were prescribed with spectacles. Of the 2,200 eyes, 59.3%(1,305 eyes) had astigmatism. Among all patients, 21.4%(235 patients) had unilateral astigmatism, 48.6%(535 patients) had bilateral astigmatism. In 1,070 eyes(535 patients) with the bilateral astigmatism, the orientation of astigmatism were 61.2% for with-the-rule astigmatism, 24.7% for against-the-rule astigmatism and 14.1% for oblique astigmatism. On the astigmatic power, -0.25~-0.50D was 47.5%, -0.75~-1.00D was 29.9%. Symmetrical astigmatism was 83.4% of the bilateral astigmatism. Asymmetrical astigmatism was 16.6% of them. From 41 to 50 years of age, 45.4% of the age had symmetrical astigmatism, 14.3% had asymmetrical astigmatism. Types of the left and the right eye in symmetrical astigmatism consisted of with-the-rule astigmatism and with-the-rule astigmatism(65.5%), against-the-rule astigmatism and against-the-rule astigmatism(25.3%), oblique astigmatism and oblique astigmatism(5.6%), etc. In asymmetrical astigmatism, with-the-rule astigmatism and oblique astigmatism was 23.6%, oblique astigmatism and with-the-rule astigmatism was 20.2%. As the results of this study, most of spectacles wearers had bilateral astigmatism that was more than unilateral astigmatism. Symmetrical astigmatism was 5 times more than asymmetrical astigmatism with no sex differences. Especially, symmetrical and asymmetrical astigmatism were more in forties than in other age groups. Over the half of symmetrical astigmatism was with-the-rule astigmatism in the left eye and with-the-rule astigmatism in the right eye. These findings will be used in prescriptions for more comfortable vision.
