Abstract

BACKGROUND

The purpose of this study was to evaluate the effect of use of contact lenses to improve visual outcome after repair of traumatic corneal wounds.

METHODS

Two groups of patients (n=30 each) with traumatic full thickness corneal wounds were entered into this study. All cases were caused by sharp objects such as a knife or piece of glass that produced a corneal full thickness wound without any other associated ocular injuries. One group was repaired and received medical treatment (non-contact lens group) and the other group was repaired and a soft contact lens was fitted over the cornea, then medically treated (contact lens group). Each patient was followed up until complete healing, the sutures were removed after about 6 weeks, and the patients were followed up for a further 6 weeks, for a complete follow-up period of 3 months, after which postoperative refraction, manifest refractive spherical equivalent, uncorrected visual acuity, and best-corrected visual acuity were measured and compared between the two groups.

RESULTS

After repair and follow-up, uncorrected visual acuity ≥0.3 (decimal system) was achieved in 19 cases (63%) in the contact lens group and in only 14 cases (47%) in the non-contact lens group (P=0.018). Best-corrected visual acuity ≥0.6 was achieved in 26 cases (87%) in the contact lens group and in only 17 cases (57%) in the control group (P=0.012).

CONCLUSION

Soft contact lenses can be used after repair of traumatic corneal wounds to improve visual outcome.

摘要

背景

本研究的目的是评估使用隐形眼镜对改善外伤性角膜伤口修复术后视力结果的影响。

方法

两组患者（每组n = 30）纳入本研究，均为外伤性全层角膜伤口。所有病例均由刀或玻璃片等尖锐物体导致，造成角膜全层伤口且无其他相关眼部损伤。一组进行修复并接受药物治疗（非隐形眼镜组），另一组进行修复后在角膜上配戴软性隐形眼镜，然后接受药物治疗（隐形眼镜组）。对每位患者进行随访直至完全愈合，约6周后拆除缝线，并对患者进一步随访6周，总随访期为3个月，之后测量并比较两组的术后验光、明显屈光球镜等效值、未矫正视力和最佳矫正视力。

结果

修复和随访后，隐形眼镜组19例（63%）患者未矫正视力≥0.3（十进制），非隐形眼镜组仅14例（47%）达到该水平（P = 0.018）。隐形眼镜组26例（87%）患者最佳矫正视力≥0.6，对照组仅17例（57%）达到该水平（P = 0.012）。

结论

外伤性角膜伤口修复后可使用软性隐形眼镜改善视力结果。
