The composition  claim 1  wherein topical administration of one 35 μL drop of said composition to each eye of a female New Zealand white rabbit provides to the corneas of said rabbit at least about 1700 ng·hr of cyclosporin A per gram of cornea of said rabbit over a period of 24 hours after said topical administration. 
     
     
         16 . The composition  claim 2  wherein topical administration of one 35 μL drop of said composition to each eye of a female New Zealand white rabbit provides to the corneas of said rabbit at least about 3300 ng·hr of cyclosporin A per gram of conjunctiva of said rabbit over a period of 24 hours after said topical administration. 
     
     
         17 . The composition of  claim 2  wherein said composition is an aqueous solution containing from 0.005% (w/v) to about 0.04% (w/v) cyclosporin A, wherein topical administration of one 35 μL drop of said composition to each eye of a New Zealand white rabbit provides at least about 17000 ng·hr of cyclosporin A per gram of cornea to the corneas of said rabbit as determined by:
 topically administering said composition to each eye of each of 15 female New Zealand white rabbit test subjects; and determining the amount of cyclosporin A in the corneas of three subjects at times of about 0.5 hours, about 2 hours, about 6 hours, about 12 hours, and about 24 hours after administration to said subject; 
 wherein the amount of cyclosporin A in the cornea is determined by only once for each subject. 
 
     
     
         18 . The composition of  claim 2  wherein said composition is an aqueous solution containing from 0.005% (w/v) to about 0.04% (w/v) cyclosporin A, wherein topical administration of one 35 μL drop of said composition to each eye of a New Zealand white rabbit provides at least about 6000 ng of cyclosporin A per gram of conjunctiva to the conjunctivas of said rabbit as determined by:
 topically administering said composition to each eye of each of 15 female New Zealand white rabbit test subjects; and determining the amount of cyclosporin A in the conjunctivas of three subjects at times of about 0.5 hours, about 2 hours, about 6 hours, about 12 hours, and about 24 hours after administration to said subject; 
 wherein the amount of cyclosporin A in the conjunctiva is determined only a single time for each subject.
