Objective〓〖WTBZ〗To compare and analyze the clinical effect of new fixed ring combined with amniotic membrane transplantation and traditional amniotic membrane transplantation in the treatment of corneal ulcer

in order to find a more safe

simple and effective way for clinical treatment.〖WTHZ〗Methods〖WTBZ〗〓A total of 64 patients with corneal ulcer who underwent amniotic membrane transplantation in our hospital from February 2016 to October 2018 were selected as the study subjects.According to the different surgical methods

they were divided into observation group and control group

32 cases in each group.The patients in the observation group were treated with new fixed ring combined with amniotic membrane transplantation

while the patients in the control group were treated with traditional amniotic membrane transplantation.The length of the operation

the pain degree score during surgery and on 1st

3rd and 5th day after surgery

and the duration of amniotic membrane survival were compared between the two groups. 〖WTHZ〗Results〖WTBZ〗〓The time of operation of observation group was shorter than that of the control group

the difference was statistically significant(P<0.05).The pain score during surgery and on 1st ，3rd day after surgery were higher in control group than those in the observation group

the difference was statistically significant(P<0.05).But there was no statistically significant difference between the two groups in the 5day postoperative pain score(P>0.05).The average amniotic membrane retention time was (10.82±2.26)days in the observation group and (5.72±1.14)days in the control group

the difference was statistically significant between the two groups(P<0.05). 〖WTHZ〗Conclusion〖WTBZ〗〓The new fixed ring combined with amniotic membrane transplantation can improve the comfort of patients with corneal ulcer

avoid intraoperative and postoperative pain

significantly shorten the operation time

and effectively improve the survival time of amniotic membrane

which is superior to traditional amniotic membrane transplantation methods.
