I had gastic sleeve on 10/17/2015 and I'm wondering is it too early to get fillers under my eyes after loosing 65 ?

I'm not sure I understand as the date you mentioned 10/17/2015 has not come yet so I don't know when you had your surgery and how quickly you lost the weight. It would also be helpful to know your age and skin turgor but I don't see any problem with mid face or tear trough volume replacement with HA filler for temporary improvement until your weight stabilizes for at least 6 months and then you can discuss with your surgeon possible advantage of skin tightening by surgical and non-surgical means.

It's a great questioin Kay.  One very common instance of “volume loss” is the area under the eyes. Under eye hollows create a worn-out, tired look. Restylane or other dermal injection products are instant solutions. Because Restylane is made of non-animal-based hyaluronic acid and is fully and safely biocompatible, allergy testing is not required.
