seeking for better solution to change indexed column size

I have a big column with size of 1024. The index (at char size 1000) has been there for the column and there are more than .5 billion data in the table. Now I have to do something to improve the performance.

I evaluated that 200 is good enough. I tried to drop off the index and tried to modify the column size to 200. I am not able to get the process successfully done.

Could someone give a suggestion what else I need to try.

Thanks for any feedback.
