PURPOSE
To present a series of patients who had 21-gauge microphacoemulsification using Sovereign WhiteStar technology.
SETTING
John A. Moran Eye Center, University of Utah School of Medicine, Salt Lake City, Utah, USA.
METHODS
Eighteen consecutive patients with cataracts judged to be 3+ or 4+ on a 4-point scale were prospectively monitored for complications, energy used during phacoemulsification, and results 1 day and 3 months postoperatively.
RESULTS
No complications occurred during nucleus removal. On a 4-point scale, the mean level of inflammation at 1 day was 0.9 +/- 0.5 (SD), with 13 patients having no corneal edema. Seven patients had an uncorrected visual acuity of 20/40 or better on the first postoperative day. At 3 months, all corneas were clear, there was no sign of anterior chamber inflammation, and all patients had a best corrected visual acuity of 20/25 or better (best-case analysis).
CONCLUSION
Results show that 21-gauge microphacoemulsification with Sovereign WhiteStar technology is safe and effective for removal of hard cataracts.

方法
对连续18例经4级分级判定为3+或4+级白内障患者进行前瞻性监测，观察并发症、超声乳化术中使用的能量以及术后1天和3个月的结果。
结果
核取出过程中未发生并发症。在4级分级中，术后1天炎症平均水平为0.9±0.5（标准差），13例患者无角膜水肿。7例患者术后第一天未矫正视力达到20/40或更佳。3个月时，所有角膜均透明，无前房炎症迹象，所有患者最佳矫正视力达到20/25或更佳（最佳情况分析）。
结论
结果表明，采用Sovereign WhiteStar技术的21G微切口白内障超声乳化术对于摘除硬核白内障安全有效。
