To compare the safety and effectiveness of trypan blue capsule staining under air vs under viscoelastic.
A total of 52 consecutive patients planned for phacoemulsification of white mature cataract were randomly assigned to trypan blue staining under air or under viscoelastic. Perioperative changes in best-corrected visual acuity (BCVA), central corneal thickness (CCT), and endothelial cell density (ECD) were compared between the two groups. The differences in operating and phacoemulsification times, staining pattern, and complications between the two groups were also recorded.
Phacoemulsification of white mature cataract was performed in 50 (96%) eyes. The median preoperative BCVA was hand movement. No significant differences in the baseline characteristics were found between the two groups. At 3 months after phacoemulsification, the median BCVA improved to 0.8. The mean CCT returned to preoperative level by 1 month postoperatively and the mean ECD loss was 11.9% 3 months postoperatively. No significant differences in median BCVA, mean phacoemulsification and operation times, mean CCT, and mean ECD were found between the two groups.
Trypan blue staining of the anterior lens capsule under air or under viscoelastic were similarly effective and safe methods for the phacoemulsification of white mature cataract.
比较空气下与黏弹剂下台盼蓝胶囊染色的安全性和有效性。
总共52例计划行白色成熟白内障超声乳化术的连续患者被随机分配至空气下或黏弹剂下进行台盼蓝染色。比较两组患者围手术期最佳矫正视力（BCVA）、中央角膜厚度（CCT）和内皮细胞密度（ECD）的变化。记录两组患者手术时间、超声乳化时间、染色模式及并发症的差异。
50只（96%）眼睛进行了白色成熟白内障超声乳化术。术前BCVA中位数为手动视力。两组间基线特征无显著差异。超声乳化术后3个月，BCVA中位数提高到0.8。术后1个月平均CCT恢复到术前水平，术后3个月平均ECD损失为11.9%。两组间BCVA中位数、平均超声乳化时间和手术时间、平均CCT及平均ECD均无显著差异。
空气下或黏弹剂下对晶状体前囊进行台盼蓝染色，对于白色成熟白内障超声乳化术而言，是同样有效且安全的方法。
