목적: 백내장수술 전후 안축장 길이에 따른 전방의 구조 및 인공수정체의 위치를 비교하고자 하였다. 대상과 방법: 백내장수술을 실시한 65안(짧은 군[안축장 < 22.5 mm], 16안; 정상군[22.5 mm < 안축장 < 25.0 mm], 33안; 긴 군[안축장> 25.5 mm], 16안)을 대상으로 수술 전후 Pentacam®과 IOL Master®로 앞방깊이의 변화를 분석하였고, Pentacam®으로 전방각, 전방부피, 각막상피-홍채전면까지의 거리 그리고 홍채전면-수정체(인공수정체)전면까지 거리의 변화를 분석하였다. 결과: 수술 전후 앞방깊이 변화는 안축장이 긴 군에서 유의하게 가장 적은 증가를 보였다(Pentacam®, p=0.000; IOL Master®, p=0.001). 또한 수술 전후 전방각의 변화는 짧은 군에서 가장 큰 증가를 보였으며(p=0.000), 전방 부피의 변화는 긴 군에서 가장 적은 증가를 보였다(p=0.000). 그리고 수술 전후 각막상피-홍채전면까지의 거리 변화는 긴 군에서 가장 적은 증가를(p=0.000), 홍채전면-수정체(인공수정체)전면까지의 거리 변화는 짧은 군에서 가장 적은 증가를 보였다(p=0.000). 결론: 짧은 안축장환자에서 백내장수술 전후 앞방깊이, 전방각 및 전방 부피가 더 크게 증가하고 홍채가 뒤로 더 밀리며, 긴 안축장환자에서는 인공수정체가 더 뒤로 많이 밀리는 것을 확인할 수 있었다. 따라서 안축장이 짧거나, 긴 군에서 백내장수술 시 술 후 인공수정체 위치를 감안하여 인공수정체의 도수를 선택해야 할 것이다.
Abstract
Purpose: In this study, we evaluated changes in the anterior chamber structure and lens position before and after phacoemulsification in eyes grouped by axial length (AL). Methods: This study included 65 eyes (16 short eyes [AL < 22.5 mm], 33 normal eyes [22.5 mm < AL < 25.0 mm], and 16 long eyes [AL > 25.5 mm]) that underwent cataract surgery. Pre- and postoperative anterior chamber depth (ACD) was measured using Pentacam® and IOL Master®. In addition, we evaluated the anterior chamber angle (ACA), anterior chamber volume (ACV), epithelium-iris distance, and iris-lens (intraocular lens [IOL]) distance. Results: The change in ACD was significantly smaller in long eyes (Pentacam®, p = 0.000; IOL Master®, p = 0.001). The change in ACA was significantly larger in short eyes (p = 0.000), and the change in ACV was significantly smaller in long eyes (p = 0.000). The change in the epithelium–iris distance was significantly smaller in long eyes (p = 0.000), and the change in the iris-lens (IOL) distance was significantly smaller in short eyes (p = 0.000). Conclusions: In short eyes, changes in ACD, ACA, and ACV were found to be larger than those of other groups as the iris moved backward. In long eyes, greater backward movement of the IOL was observed. Therefore, the appropriate IOL power should be chosen, considering the postoperative position of the IOL during cataract surgery of short and long eyes.
