Disclaimer on Cherry Eye Surgeries:

Many Veterinarians will tell you that the removal of  cherry eyes (which we perform) can cause a condition called KCS or dry eye later on in life where the eye does not produce enough tears and may require a treatment.  
Our  clinic has been removing cherry eyes for 40 years and we can honestly state we have not had one client later complain of their dog developing dry eye.  We have easily done over one thousand surgeries in that time, including removing "tucked" cherry eyes from other clinics where the tuck came undone. Again, tucks come undone more than most vets would like to admit.
The eye of the dog gets its tears from many different glands all around the eye, so removal of the cherry eye seldom causes ill effects.  Remember, a cherry eye is a swollen, compromised gland, and even though it is tucked (which is the expensive surgery many vets advocate) is still may not produce normal amount of tears.
In any event, if you are the slightest bit worried about dry eye, then by all means go to a different clinic that "tucks" the eye.  
Even though we have never seen dry eye after our cherry eye removals, our observations are not research quality facts, so take our advice with your own degree of  caution.
