Abstract

Purpose: The aim of this study was to investigate the distribution of age and gender, types of intraocular lens (IOL), and refractive errors in subjects who had cataract surgery. Methods: 2,217 subjects who had cataract surgery were surveyed at an optometry clinic in Chungbuk from 2010 to 2012. Information about IOL was obtained from case history, reflective and retroillumination images IOL by auto refracto-keratometer. Refractive errors were determined by objective and subjective refraction. Results: The mean age of the subjects was $71.74{\pm}10.62$ years. The number of cataract surgeries increased from 524 persons in 2010 to 888 persons in 2012. Of the subjects surveyed, 52 persons (2.3%) were under the 40 years of age, 144 persons (6.5%) were in 50s, 404 persons (18.2%) were in 60s, 1,132 persons (51.1%) were in 70s, 485 persons (21.9%) were in above 80s. Cataract surgery was significantly prevalent in more female (1,338 persons, 60.4%) than in male (879 persons, 39.6%). Types of IOL were 2,141 persons (96.6%) for monofocal lens, special IOLs such as multifocal, accommodative and toric lens were 76 persons (3.4%). The distribution of refractive errors after cataract operation were 1,588 eyes (38.5%) for simple myopic astigmatism, 327 eyes (7.9%) for simple hyperopic astigmatism, 601 eyes (14.6%) for mixed astigmatism, 1,240 eyes (30.0%) for myopia, 136 eyes (3.3%) for hyperopia, and 234 eyes (5.7%) for emmetropia. The uncorrected and best corrected visual acuity of the subjects were $0.55{\pm}0.25$ and $0.80{\pm}0.23$, respectively. Conclusions: The prevalence of cataract surgery increased with age until 70s years of age, it was more prevalent in men than women over 60s, and frequency of special types of IOL were low. Most cataract surgeries left residual refractive errors. Therefore even after cataract surgery it may need spectacles for better vision at either distance or near.

목적: 백내장 수술을 받은 대상자에서 성별, 연령별 분포, 사용된 인공수정체의 종류 및 수술 후의 굴절상태를 조사하고자 하였다. 방법: 2010부터 2012년까지 백내장 수술을 받고 충북 소재 안경원에 내원한 고객 2,217명을 대상으로 본 연구를 실시하였다. 문진 및 자동굴절력계에 의한 인공수정체 반사상과 역반사조명으로 수술 여부와 인공수정체의 종류를 확인하였고 타각적, 자각적 굴절검사를 실시하여 굴절상태를 결정하였다. 결과: 대상자의 평균 나이는 $71.74{\pm}10.62$세이었으며, 백내장 수술은 2010년 524명에서 2012년 888명으로 증가하였다. 백내장 수술을 받은 나이는 40대 이하 52명(2.3%), 50대 144명(6.5%), 60대 404명(18.2%), 70대 1,132명(51.1%), 80대 이상 485명(21.9%)으로 나타났다. 성별에 따른 백내장 수술 분포는 여자가 1,338명(60.4%), 남자 879명(39.6%)로 여성이 남성보다 높았다. 백내장 수술 시 사용된 인공수정체는 대부분 단초점 인공수정체로 2,141명(96.6%)이었으며, 다초점, 조절성, 토릭 렌즈와 같은 특수 인공수정체가 76명(3.4%)으로 조사되었다. 백내장 수술 후 잔여 굴절이상은 근시성단난시 1,588안(38.5%), 원시성 단난시 327안(7.9%), 혼합난시 601안(14.6%), 근시 1,240안(30.0%), 원시 136안(3.3%), 정시 234안(5.7%)이었다. 수술 후 나안시력 평균은 $0.55{\pm}0.25$이었으며 최대교정시력 평균은 $0.80{\pm}0.23$로 조사되었다. 결론: 백내장 수술은 70대까지는 증가하는 경향을 보였고, 여자가 남자보다 더 많았으며, 특수 인공수정체의 시술 빈도는 낮았다. 백내장 수술에서 대부분 잔여 굴절이상을 보였으며, 따라서 백내장 수술 후에 원거리 또는 근거리 시력 개선을 위해 안경이 필요할 것이다.
