结果 术后1~3月最佳矫正视力大于等于0.5的有550只眼(94.83%)，术中并发症，虹膜脱出30只眼(5.17%)，虹膜根部离断4只眼(0.69%)，晶状体后囊破裂6只眼(1.03%)，前房出血30只眼(5.17%)，后弹力层脱离30只眼(5.17%)。术后并发症109只眼(18.79%)包括角膜水肿50只眼（8.62%，其中内皮条样混浊40只眼），前房纤维渗出40只眼(6.90%)，短暂性高眼压10只眼(1.72%)，前房积血5只眼(0.86%)瞳孔夹持4只眼(0.70%)。

METHODS: From January 2001 to October 2002, 21 high myopia patients (39 eyes) with borderline corneal thickness were treated with LASIK. Visual acuity, keratometry readings and central corneal thickness were measured at 3 years after surgery. These data were compared with preoperative and early postoperative results.

选2001-01/2002-10在我院行LASIK手术的高度近视相对薄角膜患者21例39眼，查术后3a的视力、眼压、屈光状态、角膜曲率及中央角膜厚度，并与术前及术后早期数据进行统计学比较分析。

Keratometry measurements were obtained preoperatively, at postoperative 1 week, 1 month and 6 months respectively. SIAs were analyzed by "Cravy vector method". The mean SIA and uncorrected visual acuity were compared among the groups up to 6 months postoperatively.

测量术前、术后1周、1、3和6个月的角膜曲率，运用Cravy向量分析法计算SIA度数及方向，比较3组术后不同时间的平均SIA度数及裸眼视力。

The postoperative follow-up period was 4~21 months. postoperative visual acuity improved in 8 eyes and metamorphopsia was relieved in 9 eyes. oct confirmed retinal reattachment in 8 eyes.

术后随访4～21个月，视力提高8眼，视物变形改善9眼。oct检查显示8眼黄斑部视网膜解剖复位。2眼术后出现黄斑裂孔，其中1眼发展为视网膜脱离。

Objective To evaluate the value of OCT in the early diagnosis of macular micropathology with low visual acuity eyes after cataract phacoemulsification.

目的探讨应用光学相干断层成像术（optical coherence tomography，OCT）早期诊断白内障超声乳化术后低视力眼黄斑微小病变的作用。

Methods Thirty-one eyes of thirty-one cases with low visual acuity and without complications of ocular anterior segment and optical pathway, which were suspected macular micropathology 3 days after cataract phacoemulsification, were examined with OCT and analysed.

方法对行白内障超声乳化术后3d，最佳矫正视力低于0.3，排除眼前节和光学通路等并发症、眼底镜检查怀疑黄斑病变的患者31例31眼行黄斑OCT检查，对所得结果进行分析。

METHODS: Parents or guardians of eligible participants underwent an in-home interview and were scheduled for a detailed eye examination, including optotype visual acuity and measurement of ocular deviations.

合格的受试者父母或监护人接受一个家庭访谈并进行详细的眼科检查安排，包括视标、视力和眼偏差测量。

Results: This new chart overcame the shortcomings of different number of optotypes on each line and fewer optotype at the top of CSVAC. The measurements of this new chart had significant correlation and good agreement with CSVAC. And discovered the score difference between noisy and blank visual acuity chart.

结果：该视力表改变了每行之间视标个数不等的缺陷，与国家&标准对数视力表&检查结果之间具有较好的对应关系，并且可以掌握噪声视力表和无噪声视力表之间检测结果的差异。

Major causes of limited visual acuity were irregular astigmatism resulting from central or paracentral corneal scar or developing macular pucker.

术后视力的改善受限于因角膜中央或旁中央疤痕所致的不规则散光及发展的黄斑皱褶。

This epoxy-optical model of unilateral maxillary defects with high sensitivity and visual acuity could well meet the demand of the photoelastic experiments.

建立的单侧上颌骨缺损的环氧树脂光弹模型光学灵敏度高，直观性强，能很好的满足光弹实验的要求。
