LA200 or 300 SQ for the eye... as a precatution...like 1 cc since she is small... but she also should get some Vit A & D.... vit A is for the eyes and vit D helps with the absorption..... in fact, Multimin would be good since she is so little and it would boost her whole body systems...
The cloudiness like that seems to affect premies and some twins more from my experience... I think that seeing how she was probably abandoned, and found in poor shape... and you getting her going, that she is low on several necessary vitamins and minerals...
Also, we will use some Today or Tomorrow mastitis medicine in the tube, in the eye, a small squirt under the eye lid so it coats the eye as they blink... it doesn't hurt them and it has been our go to for pinkeye and other eye irritations and infections...
You saved her life, not going to hurt to use a little anti-biotic treatment at this point...
