To assess the efficacy and safety of indocyanine green (ICG) 0.5% and trypan blue 0.1% for anterior capsule staining in cases of white cataract.
This prospective study comprised 55 eyes of 55 patients with white cataract that had phacoemulsification with foldable intraocular lens implantation. ICG in 30 eyes and trypan blue in 25 eyes were used under air to stain the anterior lens capsule. The staining patterns and the ease of creating a continuous curvilinear capsulorhexis (CCC) were assessed; the intraoperative and postoperative complications were noted. The mean follow-up was 17.68+/-1.65 months.
Either ICG or trypan blue stained the anterior capsule uniformly. However, the staining provided by trypan blue was slightly superior. A CCC was successfully achieved in 25 eyes (100%) with trypan blue, and 29 eyes (96.7%) with ICG, respectively. There was no significant postoperative reaction in any eye.
The use of vital dyes such as ICG and trypan blue guarantees a complete CCC and makes it possible to deliver the benefits of phacoemulsification in the patients with white cataract.
评估0.5%吲哚菁绿（ICG）和0.1%台盼蓝用于白色白内障病例前囊染色的有效性和安全性。
这项前瞻性研究纳入了55例接受白内障超声乳化联合折叠式人工晶状体植入术的白色白内障患者的55只眼。30只眼使用ICG，25只眼使用台盼蓝，在空气环境下对晶状体前囊进行染色。评估染色模式以及制作连续环形撕囊（CCC）的难易程度；记录术中及术后并发症。平均随访时间为17.68±1.65个月。
ICG和台盼蓝均能均匀地对前囊进行染色。然而，台盼蓝提供的染色效果略优。使用台盼蓝的25只眼（100%）和使用ICG的29只眼（96.7%）均成功完成了CCC。所有眼术后均无明显反应。
使用ICG和台盼蓝等活性染料可确保完成CCC，并使白色白内障患者能够受益于超声乳化术。
