Abstract

Purpose: Microbial keratitis accounts for significant proportion of corneal blindness. To know the underlying etiological micro-organism, performing corneal scraping is important for initiating the correct antibiotic therapy. A study was conducted to compare the efficacy and safety of 26-gauge needle and Kimura spatula for the same.

Methods: A prospective, comparative randomized pilot study was conducted to compare Kimura spatula (group 1) to 26-gauge needle (group 2). In total, 115 patients were recruited in the 2 groups-67 in group 1 and 48 in group 2.

Results: Both the groups were comparable in adequacy of sample, microbiological staining and culture, and safety (P>0.05). However, in subgroup analysis, the number of fully adequate samples was higher and nonadequate samples was lower in the 26-gauge needle group (P=0.004).

Conclusion: Both Kimura spatula and 26-gauge needle are safe and effective tools for corneal scraping. However, in adequacy, cost-effectiveness, easy availability, disposable nature, and nondependency on sterilization unit, 26-gauge needle is superior to Kimura spatula.

26号针与木村刮刀在感染性角膜炎角膜刮拭中的比较评价：一项随机对照试验。

目的：细菌性角膜炎在角膜致盲中占很大比例。为了了解潜在的病原微生物，进行角膜刮痧对于开始正确的抗生素治疗非常重要。比较了26号针与木村刮刀的疗效和安全性。方法：进行前瞻性、比较随机的先导研究，比较Kimura刮刀（组1）和26号针（组2）。两组共纳入115例患者，其中组1 67例，组2 48例。结果：两组在标本充足性、微生物染色培养、安全性等方面具有可比性（P < 0.05）。然而，在亚组分析中，26号针组完全充足的样本数量较多，不充足的样本数量较少（P=0.004）。结论：木村刮刀和26号针都是安全有效的角膜刮削工具。然而，在充分性、成本效益、易获得性、一次性和不依赖于灭菌装置方面，26号针优于木村抹刀。

期刊介绍： Eye & Contact Lens: Science and Clinical Practice is the official journal of the Contact Lens Association of Ophthalmologists (CLAO), an international educational association for anterior segment research and clinical practice of interest to ophthalmologists, optometrists, and other vision care providers and researchers. Focusing especially on contact lenses, it also covers dry eye disease, MGD, infections, toxicity of drops and contact lens care solutions, topography, cornea surgery and post-operative care, optics, refractive surgery and corneal stability (eg, UV cross-linking). Peer-reviewed and published six times annually, it is a highly respected scientific journal in its field.
