  hyperopia
For example, hyperopia was found more commonly among female Caucasian children than among female Hispanic children (p>amp;lt;0.01).
      
Other abnormalities included medial lower epicanthal folds, abduction deficit bilaterally, large esotropia, significant hyperopia, right corneal opacity, iris and chorioretinal coloboma.
      
Because of high hyperopia (right +7.50/left +7.75) she weared soft contact lenses for years.
      
Trend analysis showed a gradually increasing likelihood of PLS with increasing magnitude of hyperopia in both eyes (Mantel-Haenszel chi-square, p = 0.001).
      
We performed a prospective study in order to elucidate thepredisposing role of axial length and hyperopia in retinal veinocclusions.

The theoretical spherical diopter after IOL implantation in 76 cases (82 eyes) were reported and the accuracy of the implanted IOL diopter among the A ultrasonic wave measured group (group A),the group calculated after general B ultrasonic wave measurement (group B)and the direct estimated group (group C) were analysed.The results demonstrated that group A was the most accurate,but it was partial to the slight hyperopia situation,group B...

The theoretical spherical diopter after IOL implantation in 76 cases (82 eyes) were reported and the accuracy of the implanted IOL diopter among the A ultrasonic wave measured group (group A),the group calculated after general B ultrasonic wave measurement (group B)and the direct estimated group (group C) were analysed.The results demonstrated that group A was the most accurate,but it was partial to the slight hyperopia situation,group B was the worst.46 67% of the eyes in group B and 17% of the eyes in group C exceeded ±2 00D,there were statistically significant differences between them(p<0 05).We suggest that the A constant which was afforded by the factory is used and the length of eye ball axis used to reckon in advance IOL diopter dont be measured by B ultrasonic wave.

本文总结76例82眼人工晶体植入术后理论球镜度,分A超精确测量组(A组),普通B超测量计算组(B组),直接估算组(C组),对预设人工晶体屈光度的准确性进行对比分析。结果A组最为准确,但仍偏向轻度远视状态,B组准确性最差,46.67%超出±2.00D,C组17%超出±2.00D,二者超出率有显著差异(P<0.05)。建议人工晶体A值使用生产厂家提供的参考值,不以普通B超测量的眼球轴长为预设人工晶体屈光度的依据。

眼角膜屈光外科术是为了修正角膜前表面曲率,从而达到校正近视、远视和散光的目的。空气·泪层的内面为一强折射层,较小的曲率变化就可以引起较大的屈光能力变化。激光和角膜组织的完美作用性使得激光能在眼屈光外科中成功地应用,已为临床应用开发了许多系统。本文对激光眼屈光外科术的临床和研究状况作一个综述。

Objective To evaluate safety and efficacy of excimer laser in situ keratomileusis (LASIK) for high and moderate hyperopia Methods LASIK was performed on 17 eyes of 9 patients using the SCHWIND KERATOM F excimer laser The range of preoperative spherical equivalent was +5 50~+9 00 D, and its mean value, (+7 18±1 00) D All the cases were followed up for 12 months or longer Results There was no serious complication during the operation No eye lost more than 1 line of the best corrected visual...

目的 观察准分子激光原位角膜磨镶术(excimerlaserin situ keratomileusis,LASIK) 治疗中高度远视的安全性及有效性。方法 对9 例(17 只眼) 高度远视患者行LASIK。术前远视度数为+5-50 ~+ 9-00 D,平均为(+ 7-18±1-00) D。术后随访观察12 个月以上。结果 术中无严重并发症,术后最佳矫正视力与术前相比,未见视力下降超过1 行以上者。术后3 个月时,屈光度基本稳定;术后12 个月时,平均远视度数为( +1-77±1-56)D,未见屈光度在0 以下者,屈光度在0~+ 1-00 D者占53% (9/17);平均裸眼远视力为0-60±0-17,其中≥0-5 者15 只眼(88% );平均裸眼近视力为0-98±0-24 ,其中≥0-5 者17 只眼(100 %) 、≥1-0 者13 只眼(77% )。结论 LASIK 对于中高度远视治疗具有良好的安全性及有效性,对于治疗参数尚需作进一步调整。
