What it means when the lens is out of position

Lens Luxation

The lens is normally suspended in about the center of the eye by zonules (tiny strands of tissue).   When the lens moves out of position it can become painful.  This can result in high pressures inside the eye.   When the lens moves to the front of the eye it is called an Anterior Lens Luxation . When it moves to the back of the eye it is called a Posterior Lens Luxation. When it is only partially loose it is called a subluxation. 

Subluxations and posterior lens luxations can be managed medically with topical drops. Our goal is to prevent the lens from moving into the front of the eye and keep pressures in a comfortable range. If your pet suddenly develops squinting seek immediate medical attention with your veterinary ophthalmologist.

Anterior lens luxation is a surgical emergency.  Surgery to remove the lens as soon as possible is imperative to comfort and retaining vision.   About 10-20% of patients develop a complication from surgery (retinal detachment, glaucoma, uveitis), these will be discussed with you prior to surgery.  After surgery your pet will require multiple eye drops and some oral medications.
