부등상시 보정안경의 임상성능 평가
목적: 부등상시 보정안경의 임상 성능을 평가하고자 하였다.
방법: 30명을 대상(남자 12명, 여자 18명, 평균 23.7세)으로 부등상시 보정안경을 처방하였다. 평소 안경과 부등상시 보정안경을 착용하고 시력, 안경배율, 부등상시도 및 입체시력을 측정하였다. 착용 1주일 후에 주관적 만족도를 평가하였다.
결과: 부등상시 보정안경 착용 후 우위안과 비우위안의 등가구면교정굴절력 차이는 평소 안경보다 증가 하였으나 유의성이 없었다(0.22D, p=0.41). 단안 교정시력의 차이는 유의하게 감소하였고(0.04, p=0.03), 양안 교정시력은 유의하게 향상되었다(0.07, p=0.00). 좌안과 우안의 안경배율 차이는 평소 안경(2.63%)보다 부등상시 보정안경(1.23%) 착용 후 더 낮았다(p=0.00). 부등상시 보정안경 착용 후 입체시는 46초각 정도 증가하였고(p=0.00), 주관적 만족도에 관한 설문에서 평소 안경보다 개선되었다. 렌즈의 가장자리 두께와 외관상 보기 흉함이 주된 개선사항으로 나타났다.
결론: 부등상시 보정안경이 부등시자에게 편안하고 만족스러운 생활을 제공하는 것으로 나타났다. 또한 부등상시 보정안경의 처방 및 조제와 관련된 임상에서 유용하게 적용할 수 있는 방법을 제시한 것으로 생각 된다.
Purpose : To evaluate the clinical performance on the aniseikonia corrective spectacles. Methods : Aniseikonia corrective spectacles were prescribed on 30 anisometropes (12 males and 18 females, mean age 23.7 yrs.). Corrected visual acuity (LogMAR), spectacle magnification, amount of aniseikonia, and stereo-acuity were measured by habitual spectacles and aniseikonia corrective spectacles, respectively. The subjective satisfaction was measured by questionnaire after wearing the spectacles for 1 week.
Results : The difference of spherical equivalent power between dominant and non-dominant eyes in aniseikonia corrective spectacles was increased compared to the case of habitual spectacles, but the difference was not significant (0.22D, p=0.41). The difference in monocular corrected visual acuity (LogMAR) has significantly decreased (0.04, p=0.03) and binocular corrected visual acuity (LogMAR) has significantly improved (0.07, p=0.00). The difference of spectacle magnification between right and left eyes of aniseikonia corrective spectacles (1.23%) was significantly lower than the difference in habitual spectacle (2.63%)(p=0.00). Stereo-acuity was improved by 46 seconds of arc in the aniseikonia corrective spectacles, and subjective satisfaction of aniseikonia corrective spectacles was significantly improved than habitual spectacles. Thick edges of lenses and ugly in appearance were found to be the main improvements.
Conclusions : It was found that aniseikonia corrective spectacles provide a visually comfortable and satisfying life for the anisometropes. Additionally, this study could suggest a practical application for clinical purposes related to the prescription and dispensing of aniseikonia corrective spectacles.
