To determine the uncorrected visual acuity (UCVA) on the first postoperative day and the fifth week after routine slow-motion phacoemulsification with posterior chamber intraocular lens (IOL) implantation.
Cincinnati Eye Institute, Cincinnati, Ohio, USA.
This retrospective chart review performed by 3 research fellows analyzed the UCVA 1 day and 5 weeks postoperatively in 100 consecutive best-case scenario eyes of 99 patients who had routine slow-motion phacoemulsification with implantation of an AcrySof single-piece IOL (Alcon). Reasons for UCVAs worse than 20/40 were sought. The stability of the visual result was analyzed.
The UCVA was 20/40 or better in 98% of eyes at 1 day. Ninety-seven percent had a UCVA of at least 20/40 by 5 weeks, confirming stability of acuity. The percentage of patients with a UCVA of 20/20 or 20/25 increased from 49% at 1 day to 77% at 5 weeks.
The UCVA 1 day after slow-motion phacoemulsification was 20/40 or better in 98% of eyes and remained stable to the last measurement at 5 weeks. Early UCVA can serve as a more sensitive measurement than best corrected visual acuity for assessing new surgical technologies and techniques.
确定常规慢动作超声乳化联合后房型人工晶状体（IOL）植入术后第1天和第5周时的未矫正视力（UCVA）。
美国俄亥俄州辛辛那提市辛辛那提眼科学院。
由3名研究员进行的这项回顾性病历审查分析了99例患者连续100只最佳情况眼中术后1天和5周时的UCVA，这些患者接受了常规慢动作超声乳化联合植入一片式AcrySof人工晶状体（爱尔康公司）。寻找UCVA低于20/40的原因。分析视力结果的稳定性。
术后1天时，98%的患眼UCVA为20/40或更好。到5周时，97%的患眼UCVA至少为20/40，证实了视力的稳定性。UCVA为20/20或20/25的患者比例从术后1天的49%增至5周时的77%。
慢动作超声乳化术后1天，98%的患眼UCVA为20/40或更好，且至5周的最后一次测量时仍保持稳定。早期UCVA可作为比最佳矫正视力更敏感的指标，用于评估新的手术技术。
