- Sedation can be done to medically widen the pupil, then push the lens into the back of the eye. Dog will need “life-long at least twice daily treatment with a drug that keeps the pupil small – which in turn ‘traps’ the lens in the back of the eye. This treatment approach is believed to be working in 8/10 patients – with an average chance of 50% that the eye will retain sight 12 months down the line,” according to the Eye Veterinary Clinic in Herefordshire, England.
