Abstract：
The study assessed the contact lens prescribing patterns and associated factors in a university optometry clinic in Trinidad and Tobago. The data relating to habitual or new contact lens (CL) prescribing patterns among wearers over a two-year period were reviewed. Pearson\'s chi-squared test and logistic regression models were used to analyze the findings. The Hosmer-Lemeshow goodness-of-fit test was used to examine the model calibration. A total of 243 CL fits were analyzed, and the Homeshow-Lemeshow goodness-of-fit test indicated a good fit (χ2 (7) = 7.296, p = 0.399). The mean age of lens wearers was 29.6 ± 12.4 (mean ± SD); the majority, 155 (63.8 %) of whom, were 21 to 40 years old. Most lenses were fitted on females (64.2% of fits overall) and about half of the wearers (n = 122, 50.2%) were prescribed lenses for cosmetic purposes. Conventional soft CL were the most prescribed modality of wear, accounting for 129 (53.1%) of the fits. Age from 21 to 40 years was the predictor of lens type prescribed, and those in that age range were four times more likely to be prescribed soft lenses compared to other ages. The patterns of CL prescribing in a university optometry clinic in Trinidad and Tobago are similar to the global market trends with slight variations.
摘要：
该研究评估了特立尼达和多巴哥大学验光诊所的隐形眼镜处方模式和相关因素。回顾了两年内与配戴者习惯或新隐形眼镜（CL）处方模式有关的数据。采用Pearson卡方检验和logistic回归模型进行分析。Hosmer-Lemeshow拟合优度测试用于检查模型校准。总共分析了243个CL拟合，Homeshow-Lemeshow拟合优度检验表明拟合良好(χ2(7)=7.296，p=0.399)。镜片配戴者的平均年龄为29.6±12.4（平均值±SD）；大多数，其中155人（63.8%），21到40岁。大多数镜片都戴在女性身上（占整体镜片的64.2％），约有一半的配戴者（n=122，50.2％）为美容目的规定了镜片。传统的软CL是规定最多的磨损方式，占拟合人数的129人（53.1%）。年龄从21岁到40岁是处方镜片类型的预测指标，与其他年龄相比，在该年龄范围内的人服用软性镜片的可能性是其他年龄的四倍。特立尼达和多巴哥大学验光诊所的CL处方模式与全球市场趋势相似，但略有变化。
