pasteur pipette can be use because there is no sharper edge it will be easy

Micropippete can't be used for intra-occular administration as far as animal ethics are concerned. You can use 1 mL syringe (graduated syringe without needle) for intra-occular administration. You can use pasture pippette but it must be graduated otherwise you will not be able to know the volume of test item to be administration in the eye.
