Abstract

Purpose: To compare the clinical outcome between Tecnis ZM900 and Tecnis ZA9003. Methods: We reviewed 20 eyes of 11 patients implanted with Tecnis ZM900 and 20 eyes of 20 patients implanted with Tecnis ZA9003. The clinical outcomes of these two intraocular lenses were evaluated one month after operation and consisted of distant, intermediate, and near visual acuity; depth of focus; contrast sensitivity; wavefront aberration; and patient satisfaction. Six months after the operation a reevaluation was performed for the group who had received the Tecnis ZM 900 implant. Results: Near and intermediate vision was better in the Tecnis ZM900 group. There were no statistical differences between the two groups with respect to distant vision and wavefront aberration. Contrast sensitivity was better in the Tecnis ZA9003 group and depth of focus was deeper in the Tecnis ZM900 group. There were no statically significant differences in the result between one month and six month after the operation. Conclusions: The Tecnis multifocal ZM900 IOL can be effective at improving patient satisfaction after cataract surgery as well as for correcting presbyopia.

목적: 회절 방식의 다초점 비구면 인공수정체 Tecnis ZM900과 단초점 비구면 인공수정체 Tecnis ZA9003 삽입 후 수술 결과를 비교하고자 하였다. 대상과 방법: 다초점군 11명 20안, 단초점군 20명 20안을 대상으로 수술 1개월 후 시력, 대비감도, 고위수차, 초점심도를 비교하였고, 다초점군에서는 양안과 단안의 시력, 대비감도 및 초점심도를 비교하였으며, 환자 만족도를 조사하였고, 수술 6개월간 추적 관찰하여 수술 1개월 후 결과와 비교하였다. 결과: 다초점군에서 근거리 및 중간거리 시력이 더 좋았고(p<0.05) 원거리 시력은 유의한 차이가 없었다. 대비감도는 단초점군이 더 좋았고(p<0.05), 초점심도는 다초점군에서 더 깊었으며(p<0.05) 고위수차는 두 군간의 유의한 차이는 없었다. 다초점군에서 단안 및 양안의 시력, 대비감도, 초점심도를 비교한 결과 통계적으로 유의한 차이는 없었다. 다초점군의 6개월 관찰 결과 1개월 후 결과와 유의한 차이는 없었다. 결론: Tecnis 다초점 인공수정체는 백내장 수술 환자만족도 개선에 도움이 될 것으로 생각하며 노안 교정에도 유용할 것으로 생각된다.
