AIM:To invest the clinical effect of He-Ne laser on the therapeutic program of the herpes zoster keratitis(HZK).

METHODS: We have set the He-Ne laser and medicine combination therapy as observation while the medicine therapy as contrast according to clinic case-control method. We have calculated the quantity data from both ocular and whole body aspects.

RESULTS:The skin crusts generating rate was better in the observation group at 10^th day of therapeutic program. The pain relief rate was better in the observation at 5^th day of program(χ²=4.03, P<0.05). The difference of the patients' keratitis between both groups was significant(t=4.227, 8.208; P<0.01), the general results of observation group were better( χ²=4.49, P<0.05). We did not found any serious complications during the whole program.

CONCLUSION:The He-Ne laser improves the treatment efficiency of medicine to the HZK.
