We reviewed 424 requests for soft contact lens cleaning that had been sent to a service laboratory in Caracas, Venezuela in the course of a year. We believe that this sample represents a cross-section of problem lenses in a tropical country (Venezuela). Among the cases for which data were available, there were more extended wear lenses than daily wear lenses sent for cleaning. A majority of the lens wearers were females and/or over age 20. The wearers were experienced handling their lenses. A relatively high percentage of them (52 of 184; 28%) used homemade solutions (unpreserved saline, distilled water, tap water, and/or baby shampoo) for the care and cleaning of their lenses. Although the reasons for referral were similar to those reported from temperate zones, we found a much higher incidence of combined deposits (protein-lipid-inorganic) than reported in studies carried out in other countries. Fungal invasion seemed more prevalent in our area than in temperate zones. From our results, the need for better education of wearers is obvious. In addition, special measures for the control of fungal growth may be required locally. The high incidence of this type of growth may be partly related to tropical conditions that favor the dispersal of fungal spores.
我们回顾了一年内发送至委内瑞拉加拉加斯一家服务实验室的424例软性隐形眼镜清洁请求。我们认为，该样本代表了一个热带国家（委内瑞拉）问题镜片的横断面。在有数据可用的案例中，送去清洁的长戴型镜片比日戴型镜片更多。大多数镜片佩戴者为女性和/或20岁以上。佩戴者有处理镜片的经验。其中相当高比例的人（184人中的52人；28%）使用自制溶液（未保存的盐水、蒸馏水、自来水和/或婴儿洗发水）护理和清洁镜片。尽管转诊原因与温带地区报告的相似，但我们发现混合沉积物（蛋白质 - 脂质 - 无机物）的发生率比其他国家开展的研究报告的要高得多。真菌侵袭在我们地区似乎比温带地区更普遍。从我们的结果来看，显然需要对佩戴者进行更好的教育。此外，当地可能需要采取特殊措施来控制真菌生长。这种类型生长的高发生率可能部分与有利于真菌孢子传播的热带条件有关。
