This work set out to investigate if there was an association between subjective comfort and both subjective and measured vision during the use of contemporary daily disposable soft toric contact lenses.
Thirty-eight habitual soft contact lens wearers wore each of three daily disposable toric lenses for one week in a prospective, crossover, randomised, single-masked study. The following clinical measures were recorded at dispensing and follow-up visits: biomicroscopy scores, lens fitting (including rotation and rotational stability), high and low contrast visual acuity, subjective vision quality and subjective ocular surface comfort. Subjective scores were collected using 0-10 numerical grading scales. Comfort scores were analysed using a linear regression model with age, sex, visit, phase of crossover ('phase'), lens type, lens rotation, lens rotational stability, visual acuity, cylinder power and subjective vision quality as factors of interest and then refined using backward stepwise regression.
Thirty six participants (31.1 ± 13.5 years) completed the study. Comfort scores were found to be associated with subjective vision quality (F = 127.0 ; p < 0.0001), phase (F = 7.2; p = 0.001) and lens type (F = 4.9; p = 0.009). Greater comfort scores were observed with greater subjective vision quality scores. Visual acuity was not statistically significant in the model.
This work suggests that symptoms of ocular discomfort may be more intense if there is also perceived visual compromise in daily disposable soft toric lenses. There was a stronger positive correlation between comfort and subjective vision quality compared with comfort and measured visual acuity.
本研究旨在探讨在使用现代日戴型软散光隐形眼镜时，主观舒适度与主观和客观视力之间是否存在关联。
38 名习惯性软性隐形眼镜佩戴者参与了一项前瞻性、交叉、随机、单盲研究，他们在一周内分别佩戴三种日戴型软散光隐形眼镜。在配镜和随访时记录了以下临床测量值：生物显微镜评分、镜片适配（包括旋转和旋转稳定性）、高对比度和低对比度视力、主观视力质量和主观眼部舒适度。主观评分使用 0-10 数字评分量表进行评估。舒适度评分使用线性回归模型进行分析，其中年龄、性别、就诊时间、交叉阶段（“阶段”）、镜片类型、镜片旋转、镜片旋转稳定性、视力、散光度数和主观视力质量作为感兴趣的因素进行分析，然后使用逐步后退回归进行细化。
36 名参与者（31.1±13.5 岁）完成了研究。舒适度评分与主观视力质量（F=127.0；p<0.0001）、交叉阶段（F=7.2；p=0.001）和镜片类型（F=4.9；p=0.009）相关。主观视力质量评分越高，舒适度评分越高。视力在模型中没有统计学意义。
本研究表明，如果日戴型软散光隐形眼镜的主观视觉质量也受到影响，眼部不适症状可能更为严重。舒适度与主观视力质量之间的相关性比舒适度与客观视力之间的相关性更强。
