目的:确定抛弃型水凝胶接触镜及其护理液细菌定植的比率,并确定污染的病原体.方法:按目的抽样进行横断面研究.从马来西亚Sains大学健康校园的本科学生接触镜配戴者中收集100片水凝胶接触镜.所有的镜片和护理液均送微生物培养和革兰氏染色.结果:大多数的研究参与者为女性(98%).平均年龄21.36±1.63岁.41片接触镜(82%)呈现阳性细菌定植,32%的护理液可见阳性细菌定植.最常见的病原体是凝固酶阴性葡萄球菌、金黄色葡萄球菌和链球菌,而在接触镜中能更频繁地分离出假单胞菌和沙雷氏菌.结论:配戴接触镜有导致镜片和护理液细菌定植的潜在危险.建议在镜片护理和配戴过程中采取最大程度的预防措施并严格遵守卫生做法.

AIM:To determine the rate of bacterial colonization in hydrogel disposable contact lenses and solutions and to identify the contaminating organisms.METHODS:A cross sectional study with purposive sampling was carried out.One hundred hydrogel contact lenses were collected from wearers among undergraduate students of Health Campus,University Sains Malaysia.All lenses and storage solutions were sent for microbiological culture and gram staining.RESULTS:The majority of study participants were females(98%).The mean age was 21.36±1.63 years.Forty-one subject participants(82%)showed positive bacterial colonization of the lenses.From storage solutions 32% yielded positive colonization by bacteria.The most common organisms were coagulase negative staphyJococcus,Staph aureus and streptococci while Pseudomonas sp.and Serratia sp.were isolated more frequently from contact lenses.CONCLUSION:Contact lens wearing is potentially dangerous as a result of high rate of bacterial colonization of the lenses and its storage solutions.Extreme precaution and adherence to strict hygienic practice is recommended during lens handling and wearing.
