Surface wettability and hydrophilicity of pHEMA soft contact lenses were investigated utilising adherent liquid/laser method (ALLM) and adherent liquid/balance method (ALBM). The measurements were carried out before and after periods of 15 min to 2 h contact lens wear. Following the lens removal, the wetting angle of the contact lens of the left eyes and hydrophilicity (maximum force) of the contact lens of the right eyes of the five subjects were immediately measured, respectively, without cleaning (one value for pre-lens wear and eight values for post-lens wear). The wettability of soft contact lenses significantly increased after 15 min of wearing and stabilised at a maximum level after 30 min in vivo. Contact lens hydrophilicity was found to decrease as the lens was worn. The reduction continued for up to 1.5 h of wearing, for male cases, and for the female cases, the reduction continued until the end of the experiment.
利用附着液体/激光法(ALLM)和附着液体/天平法(ALBM)研究了聚甲基丙烯酸羟乙酯(pHEMA)软性隐形眼镜的表面润湿性和亲水性。在佩戴隐形眼镜15分钟至2小时的时间段前后进行测量。取下镜片后,立即分别测量五名受试者左眼隐形眼镜的湿润角和右眼隐形眼镜的亲水性(最大力),无需清洗(佩戴前一个值,佩戴后八个值)。软性隐形眼镜的润湿性在佩戴15分钟后显著增加,并在体内佩戴30分钟后稳定在最高水平。发现隐形眼镜的亲水性随着佩戴而降低。对于男性受试者,这种降低持续到佩戴1.5小时;对于女性受试者,这种降低持续到实验结束。
