Abstract

Background and aim In this study we aimed to assess the short-term outcome of phacoemulsification in a tertiary hospital and to analyze which are the factors affecting visual outcomes. Patients and methods This is a prospective cohort study that included 50 eyes (50 patients) with senile cataract, phacoemulsification was done between September 2019 and December 2020. Comprehensive ophthalmic examination: preoperatively, first day, 1 week, and 1 month postoperatively was done. The changes in best-corrected visual acuity, corneal curvature, and intraocular pressure were compared. Double-angle plot of the corneal surgically induced astigmatism (SIA) was calculated, including centroid values (C-SIA) and mean of surgically induced astigmatism (M-SIA). Results The mean age was 64.86±8.48 years, 60% right eyes. No intraoperative complications. Best-corrected visual acuity (log MAR) was 1.079±0.66 with significant improvement postoperatively (P=0.00). Mean intraocular pressure was 16.88±3.193 with significant decrease postoperatively (P=0.04). Corneal astigmatism significantly increased from 0.939±0.57 D preoperatively to 1.146±0.67 D postoperatively (P=0.02). The M-SIA was 0.65±0.32 D (OD), 0.55±0.31 D (OS), the centroid of surgically induced astigmatism C-SIA was 0.28±0.67 D at an axis of 68° (OD), and 0.15±0.72 D at an axis of 76° (OS). Good visual acuity (>20/40) was achieved in 80% and 20/20 in 22%, dense cataract significantly influences the visual outcome (P=0.02). Conclusions This study implicates that in the absence of ocular comorbidity, the visual outcome of phacoemulsification is satisfactory in short-term follow-up, and effort should be exerted during surgery to deal with ocular conditions requiring complex surgery such as dense cataract and to observe every postoperative visual progression for interventions.

三级医院白内障手术的近期疗效
背景和目的在本研究中,我们旨在评估三级医院超声乳化术的短期效果,并分析影响视觉效果的因素。患者和方法这是一项前瞻性队列研究,包括50眼(50名患者)老年性白内障,超声乳化术于2019年9月至2020年12月进行。眼科综合检查:术前、术后第1天、1周、1个月进行检查。比较最佳矫正视力、角膜曲率和眼压的变化。计算角膜手术诱导散光(SIA)的双角图,包括质心值(C-SIA)和手术诱导散光平均值(M-SIA)。结果平均年龄64.86±8.48岁,60%为右眼。无术中并发症。最佳矫正视力(log MAR)为1.079±0.66,术后有显著改善(P=0.00)。平均眼压为16.88±3.193,术后显著下降(P=0.04)。角膜散光从术前的0.939±0.57D显著增加到术后的1.146±0.67D(P=0.02),手术诱导散光C-SIA的质心在68°(OD)轴处为0.28±0.67 D,在76°(OS)轴处则为0.15±0.72 D。80%和22%的患者获得了良好的视力(>20/40),致密性白内障对视觉效果有显著影响(P=0.02),在手术过程中应努力处理需要复杂手术的眼部疾病,如密集性白内障,并观察每一次术后视觉进展以进行干预。
