Dog Cataract Surgery Before And After

Is My Dog A Candidate For Cataract Surgery

In order to determine the answer to that question, your dog will need to have his/her eyes evaluated by a veterinary ophthalmologist. We need to determine that your pet will have a reasonable chance of vision after the surgery has been performed. In addition to an eye examination, some diagnostic tests may be required. Typically an electroretinogram is performed to assess the function of the retina and occasionally, an ultrasound of the eye may be required.

Treating The Underlying Cause

If your dogs cataracts have developed due to a specific condition, they will need that condition treated to limit further damage to their eyes. It is important to understand that treating the underlying condition may slow the development of your dogs cataracts, but wont get rid of them. The only way to get rid of cataracts is to remove them.

How Are Cataracts Diagnosed In Dogs

If you suspect that your dog is having vision trouble or if you notice that your dog’s eyes appear cloudy see your vet for a thorough examination. Your vet may refer you to a Veterinary Ophthalmic Specialist who will be able to run tests to confirm the diagnosis, and recommend appropriate treatment for your dog.

Some Background Information

A normal young lens is clear like glass. It acts like a magnifying glass to make objects up close appear crisply detailed and clear by focusing near objects accurately onto the retina.

When the normally clear lens inside the eye becomes opaquely cloudy, this impairs vision and is called a cataract.

Cataract Surgery

There are no medications proven to dissolve cataracts in people or in pets. Therefore, the treatment of choice for advanced, vision-impairing cataracts is surgery. The cloudy lens is removed by phacoemulsification technology and a replacement lens is usually surgically implanted.

Here are Three Good Resources on Veterinary Cataract Surgery:

The photo at left shows an operating room at Veterinary Vision where cataract surgery is being performed.

Cataract surgery is performed using phacoemulsification to break up the cloudy lens and aspirate it from the eye.

The replacement lens is made of an inert material which is well tolerated and inhibits cataract regrowth.

Dog Cataract Surgery Considerations

Cataract surgery is the preferred method of curing cataracts in dogs, and its success rates are high. Over 90 percent of dogs will have improved vision after surgery.

Owners should still consider that there is a long recovery period and their dog will need to avoid extreme exercise. But once healed, your dog should benefit from permanent improved vision, unless altered by other conditions. There are risks associated with every surgery and a cataract procedure in dogs is no different. Some side effects include a scar tissue which can limit vision, the risk of eye pressure known as glaucoma, retinal detachment, infection, and anesthesia side effects.

However, for the majority of dogs, the surgery goes smoothly with very few complications, if any at all.

The Surgical Procedure: Phacoemulsification

Niko Before And After Cataract Surgery

Cataract surgery involves removal of the lens fibers. In order to access the lens, an incision is made in the cornea and a round hole is torn in the front of the lens capsule. A small pen-like instrument is introduced into the eye and through the hole in the lens capsule. This instrument produces ultrasonic vibrations that break up the lens material as it simultaneously vacuums this material to remove it from the eye

After the lens fibers are removed, a lens implant may be inserted into the lens capsule. The lens implant is not necessary for vision, but significantly improves near vision. At the completion of the procedure, the cornea is then closed with tiny stitches that absorb over the next four weeks.

Cataract Surgery Procedure In Dogs

Cataracts can be difficult to diagnose by anyone other than a professional vet ophthalmologist. Expertise is needed to distinguish the similarity between a harmless age-related hardening of the lens which does not affect vision, and the visually impairing cataracts. Both give the impression of clouding.

Owners should consider that a successful surgery cannot give the dog perfect vision, but by removing the affected lens and replacing it with an artificial one, it will significantly improve the pet’s vision and quality of life.

If cataract surgery is the best option, your dog will undergo a complete physical exam with blood and urine tests.

Your dog will need to visit the clinic again, once the test results are ready, to have two further tests. Electroretinography, to determine retinal function, and an ultrasound to seek any retinal detachment. If retinal function is reduced or the retina is detached, surgery is unlikely to proceed.

If all test results are satisfactory, your dog will be placed under general anesthesia for the surgery. The procedure for dogs is very similar to the procedure for humans.

The veterinary ophthalmologist will cut into the eye or eyes to make a hole in the capsular bag holding the lens. A special probe will then emulsify and remove the cataract. Then, an intraocular lens commonly known as an artificial lens will be installed in its place. The surgery ends with the eye being sutured shut with absorbable sutures.

How Long Will It Take For A Dog To Recover From Cataract Surgery

The initial healing period after cataract surgery in dogs is approximately two weeks. Your puppy will need to wear an E-collar during that period. Their activity will be limited to leash walking only. You will also need to give your dog several eye drops and oral medications. Following your vets instructions carefully is essential to get a good result for your dogs vision.

Depending on the 2-week follow-up appointment results, your dogs medications may be reduced. However, some puppies will need to remain on medication permanently.

Without surgery, cataracts can grow larger, causing additional loss of sight. Eventually the dog will likely go completely blind, explains Dr. Martins. If, for personal or medical reasons, surgery is not an option for a pet, it is important to control the inflammation in the eye secondary to the cataract. We want to prevent lens shifting or the development of glaucoma.

Dr. Martins notes that a dog can still have a great life without vision, if cataract surgery is not elected, as long as there is appropriate care and monitoring to make sure the animal is not in any pain.

Animals without vision learn to rely on other senses, she notes. However, if surgery is an option, it will significantly improve the animals quality of life.

Dog Cataract Surgery Process

Every veterinary hospital has its own process, but in most cases, you will drop your dog off either the morning of surgery or the night before. While some special care is required for dogs with diabetes, in all cases your vet will provide you with detailed instructions regarding feeding and care leading up to surgery day. Be sure to follow your vet’s instructions carefully.

Pre-Surgery Testing

  • Before the surgery begins your dog will be sedated and an ultrasound will be performed to check for issues such as retinal detachment or rupture of the lens. An electroretinogram will also be done in order to confirm that your dog’s retina is working properly. If these tests turn up any unexpected issues, unfortunately, your dog may not be suitable for cataract surgery.

Surgical Procedure

  • Cataract surgery will be performed under a general anesthetic. A muscle relaxant will also be administered to help your dog’s eye sit in the correct position for the operation. Cataracts in dogs are removed using a technique called phacoemulsification. This procedure uses an ultrasonic device to break up and remove the cloudy lens from the dog’s eye, and is the same procedure that is used in cataract surgery on people. Once the lens with the cataract has been removed an artificial lens implant can then be placed in the eye to allow images to be focused clearly onto the retina.

Post-Surgery

What Are Cataracts In Dogs

A cataract is a common eye disorder that affects humans as well as our furry friends. A cataract is a cloudy area that forms in the lens of the eye, which is normally clear. The clouding prevents light from passing normally through the lens to the back of the eye. As a result, the cataract can cause blurry vision . Dogs can develop a cataract in one or both eyes, but the condition is frequent in both eyes.

What Is Cataract Surgery

Just like a camera, a dog’s eyes contain clear lenses they use to focus. Those clear lenses can sometimes form an opacity that can make it difficult for them to see. It can start with blurred spots and can end with a complete loss of vision.

The best form of treatment for severe cataracts in dogs is surgery, and it’s a common procedure performed routinely by veterinary ophthalmologists. However, not all dogs require surgery since cataracts don’t always affect the dog’s vision. A veterinarian ophthalmologist should be consulted to evaluate the severity of cataracts and decide on the next course of action.

If surgery is the best option, the dog will then undergo a series of tests to confirm whether the procedure would improve the dog’s quality of life.

Are There Any Risks With This Surgery

Dog Cataract Surgery Cost And Time Investment

Cataract surgery for dogs obviously comes at a price, but one that most owners feel is well worth paying. After the initial diagnosis by your regular veterinarian, you will have a consultation with the veterinary ophthalmologist. They will confirm the diagnosis and perform other tests to evaluate the eye.

These tests usually include ultrasound imaging of the eye and an electroretinogram to determine if the retina is still healthy. A pre-op blood panel will be done to rule out serious diseases that might make anesthesia risky. You might need to visit the veterinary ophthalmologist once for diagnostic testing and a physical exam and again on the day of the surgical procedure.

What Is The Treatment For Cataracts In Dogs

In many cases, cataracts in dogs can be surgically removed and replaced with an artificial lens. Unfortunately however, not all dogs with cataracts are suitable candidates for this surgery. If your dog has a pre-existing retinal detachment, retinal degeneration, glaucoma, or severe inflammation of the eyes, cataract surgery may not be an option for your pooch.

When it comes to saving your dog’s vision, early diagnosis of conditions such as cataracts is important. Regular twice-yearly wellness exams give your vet the opportunity to check your dog’s eyes for signs of developing cataracts and recommend treatment before they become more serious.

If your pup has been diagnosed with cataracts and is a good candidate for surgery, the sooner the surgery can be performed, the better the long-term outcome for your pet is likely to be.

Pet parents with dogs who are not suitable for surgery should rest assured that, although their dog will remain blind they can still enjoy a good quality of life. Dogs are very adaptable creatures and with a little practice your dog will adapt and be able to navigate their home environment well by using their other senses to guide them.
