AIM: To evaluate the effect of variety factors on the patient's adaptability and subjective evaluation after wearing Menicon-Z rigid gas permeable contact lens(RGPCL).

METHODS: Totally 39 patients were recruited in this study. The clinic data including age, gender, spherical, astigmatism, corneal thickness, corneal curvature, basic tear and living areas were analyzed for their impact. Patients evaluated comfort and visual stability after wearing Menicon-Z RGPCL for a month.

RESULTS: The average adaptation period after wearing RGPCL was 6.41 ± 4.64 days. The age factor had a significant influence of the adaptation period(F=4.07, P=0.025). Patient's discomfort caused by foreign body sensation(0.62±0.71)and eye dry sense(0.64±0.63)after wearing RGPCL for a month.

CONCLUSION: Patients adapted to Menicon-Z RGPCL in about a week. The younger the more easily adapted to the RGPCL. The main impact factor of patient's adaptation period is comfort. Detailed guidance and corresponding treatment is an important means to resolve their symptoms and long-lasting wearing.
