Your pet has received a contact lens over his or her cornea. This a therapeutic lens only and will not significantly affect your pet's vision. It is used in most cases to aid healing of a corneal ulcer.
A common question is how long will the contact lens remain on the eye. It is our desire that it remain until removed and this is the case for most patients. Therefore, for this (and other) reasons your pet will need at least one recheck examination.
In order for the contact lens to serve its purpose, it needs to remain on the eye for a certain amount of time. This means that your pet cannot rub at the eye or the lens can be dislodged. Use of an Elizabethan collar is usually advised for this reason. Even without self-trauma, pets can occasionally get the lens out. Dogs and cats have a third eyelid and it can play a role in premature lens loss.
In most cases where a lens has been placed on the eye, the cornea was first debrided. Although this is beneficial as it can stimulate ulcer healing, it can also temporarily make your pet more uncomfortable. For this reason, we commonly receive phone calls due to concern that the contact lens is causing pain. In the vast majority of cases, the discomfort is actually due to the condition of the eye or was temporarily exacerbated by the debridement.
We find displacement of the lens on the eye to be a rare complication of lens use. If you are ever concerned about the lens position, please let us know and we are happy to check it out to make sure that there is not a problem.
Last but not least, if you feel that your pet is uncomfortable, please let us know so that the medical plan can be adjusted. We share a common goal of wanting your pet as comfortable as possible as quickly as possible
