Abstract
To compare the creep mechanical characteristics of the normal cornea and the morbid cornea and provide the biome-chanical parameter for the clinical medicine. 20 corneas were divided into two groups. 10 corneas (the rest part of the cornea after transplantation) belonged to the normal group and the other 10 ones (the abandoned part of the severe ulcer corneal after operation) belonged to the morbid group. The creep experiment was done with the electronic universal testing machine, increasing the stress at the speed of 0. 1 MPa per second. The data with the normalized analysis method was analyzed. The creep quantity of the normal group in 7 200 s was 0. 16% . The creep quantity of the morbid one in 7 200 s was 0. 12%. The creep quantity of the normal group was more than the morbid one and the differences were significant (P < 0. 05). The creep curves of the normal group and the morbid one change exponentially. The creep characteristics of the cornea in the morbid group has changed.关键词
