목적 : Surgically induced astigmatism (SIA) has emerged as a major interest because change in corneal astigmatism can lead to decrease in uncorrected visual acuity and patient discomfort. This study aims to evaluate SIA and identify factors correlated with SIA after trabeculectomy.
방법 : We retrospectively reviewed medical charts of patients who were treated with trabeculectomy at 120° meridian (superotemporal area on right eye and superonasal area on left eye) by the same surgeon. Preoperative keratometric data were compared with data collected from 2 months to 12 months postoperatively. SIA was evaluated using Naeser’s polar value analysis.
결과 : 51 eyes of 51 patients were enrolled. Using the Naeser method, ΔKP(120) was calculated as 0.7±0.7 (0.82@104°), which means with the rule change. After the surgery, the combined mean polar values changed significantly (Hotelling T2=22.47; p<0.001). Multivariate analysis of variance (MANOVA) indicated that postoperative intraocular pressure (IOP) and location of surgery were independent factors significantly associated with SIA (p=0.002 and 0.03, respectively).
결론 : Trabeculectomy at 120° meridian was not astigmatically neutral. In addition, The SIA after trabeculectomy appears to be greater in the eyes with low postoperative IOP and superonasal surgical wound rather than superotemporal wound.
