유리체절제술과 백내장병합수술 후 앞방 깊이와 안구 길이 및 굴절력의 변화 측정

Abstract

Purpose: To evaluate the changes of anterior chamber depth (ACD), Axial length (AXL) after combined vitrectomy and cat-aract surgery and to analyze the association with refractive errors. Methods: In 22 eyes who underwent combined vitrectomy and cataract surgery (PPV-Phaco group), 20 eyes who under-went vitrectomy-only (PPV-only group) and 28 eyes who underwent uncomplicated cataract surgery (Phaco-only group), ACD and AXL were measured with IOL master (Carl Zeiss Jena, Germany) preoperatively and 3 months postoperatively. We compared the preoperative desired refraction and postoperative 3 months refraction. Results: ACD were increased in PPV-Phaco group and Phaco-only group (all, p < 0.001) and this change was more prominentin PPV-Phaco group (p = 0.030). In PPV only group, ACD was decreased (p < 0.001). The AXL after surgery was not significant different from the preoperative AXL in PPV-Phaco and PPV only groups (p = 0.612, p = 0.090). But the AXL was decreased in Phaco-only group (p = 0.022). Hyperopic shifting were noticed in PPV-Phaco and phaco-only groups, but my-opic shifting was noticed in PPV-only group. However, these changes were not statistically significant (p = 0.292, p =0.251, p = 0.068).Conclusions: ACD was increased after combined vitrectomy and cataract surgery. AXL was not changed. The hyperopic shifting was noticed after combined vitrectomy and cataract surgery, but was not statistically significant.
