RESUMO
Objective To observe the effect of postoperative central vault on the anterior chamber after implantation of im-plantable contact lens V4c .Methods To carry out a retrospective study of 56 eyes with implantable contact lens V4c implantation in Chongqing Bright Eye Hospital from November 2 ,2014 to February 5 ,2015 ,examined anterior chamber angle before surgery ,the anterior chamber angular width (ACA) and anterior chamber volume (ACV) were measured by pentacam .the postoperative central vault and ACA and ACV during the first and third and sixth months after surgery were measured ,the pigment grade in anterior chamber after operation were recorded .The change of ACA and ACV of the 56 eyes was correlation analyzed .Results At first month after surgery ,the postoperative central vault was 250 ~ 765 μm ,the reduced amount of ACA was (13 .67 ± 1 .67)° ,the re-duced amount of ACV was (94 .23 ± 17 .02)mm3 .At the third month ,the postoperative central vault of the 55 eyes was 239 ~ 761μm ,the reduced amount of ACA was (13 .70 ± 1 .68)° ,The reduced amount of ACV was (93 .6 ± 17 .48)mm3 .At the sixth month , the postoperative central vault of the 51 eyes was 246 ~ 761 μm ,the reduced amount of ACA was (13 .60 ± 1 .69)° ,the reduced a-mount of ACV was(94 .29 ± 17 .80)mm3 .No case of pigment was found for grade Ⅱ .The statistical comparison of the amount of ACV and ACA decreased in different postoperative central vaults showed that the difference was statistically significant ,there were statistically significant differences in the amount of ACV and ACA between different central postoperative central vault(P< 0 .05) . Conclusion Anterior chamber angle was narrowed and anterior chamber volume decreased in the posterior chamber intraocular lensimplant-ation after implantable contact lens V4c implantation ,the postoperative central vault is related to the change of anterior chamber angle and ACV .Appropriate postoperative central vault has positive clinical significance for keeping anterior chamber angle open .
RESUMO
OBJECTIVE： To observe the therapeutic effects of 0.3％ levofloxacin eyedrops on the acute bacterial conjunctivitis and keratitis.METHODS： The patients were randomly divided into treated group and control group.They were given 0.3％ levofloxacin and 0.3％ ofloxacin eyedrops respectively.The effects were compared between two groups.RESULTS： From April 1998 to December 1998， 132 cases were enrolled in the study： treated group 67 cases， control group 65 cases.The positive rates of bacterial culture were over 80％ in both groups.It showed that there was no significant difference between two eyedrops in the curative and effective rates， but the mean cure day of keratitis in levofloxacin group was significantly shorter than that in ofloxacin group.CONCLUSION： Levofloxacin eyedrops is effective and safe in treating bacterial conjunctivitis and keratitis， and the therapeutic course is short and no obvious ARDs occur.
