摘要

傳統上，矯正高度散光可使用普通眼鏡或硬式隱形眼鏡，嚴重者則以手術矯正之，本研究採用重疊型隱形眼鏡組－一片軟式隱形眼鏡加上一片硬式隱形眼鏡來矯正高度散光，可得到手術矯正的程度，卻具備光學矯正法簡便的優點。

A piggy-back contact lens system is one of many possibilities for correcting high and/or irregular astigmatism. It consists of a soft lens put on the cornea and a hard lens fitted onto the soft one. It efficacy is much higher than that of ordinary glasses or hard contact lens, while being safer and easier to use than surgical corrections. We used a modified method of fitting, by J.A. Baldone a modification of the first reported use of piggy-back contact lenses to correct the high astigmatism of 8 patients in 1984. After careful follow ups of at least 6 months, every patient showed better vision than that obtained from glasses correction. There, however, were certain problems with wearing it such as foreign body sensations, difficulties in wearing, time spent on maintenance and unstable vision while blinking. We concluded that piggy-back lenses can offer satisfactory vision, but patient compliance might be poor due to the problems mentioned above.
