So, without further ado, let’s start with the main thing.

What are Cataracts in Dogs?

Cataracts in dogs refer to the clouding of the lens in their eyes, which leads to impaired vision.

The lens, normally clear and transparent, becomes opaque and obstructs the passage of light, causing vision problems.

Cataracts can range in severity from minor cloudiness to complete opacity, resulting in blindness.

They can occur due to various factors, including age, genetics, diabetes, trauma, inflammation, or certain medications.

Cataracts can develop gradually or rapidly, and they may affect one or both eyes.

What causes cataracts in dogs?

  • Age: Just like humans, dogs can develop age-related cataracts as they grow older

  • Certain dog breeds are more prone to developing cataracts due to genetic predisposition
  • Trauma: Eye injuries or trauma can lead to the formation of cataracts in dogs

  • Underlying health conditions such as diabetes mellitus or hypothyroidism
  • Chronic inflammation in the eyes, often associated with conditions like uveitis

How Can I Know if my Dog has Cataracts?

There are many symptoms but sometimes they cannot be detected so easily, as it is slowly but progressively escalating.

That is why we should always be aware of any slightest change in our pets, they are alerts and can help us to act before it is too late.

In addition, you should go to the veterinarian immediately so that he/she can indicate the steps to follow for treatment.

Signs of cataracts in dogs may include:

  • Cloudy or opaque film covering the pupils

  • Changes in pupil size or shape

  • Difficulty seeing in dimly lit areas

  • Reluctance to climb or jump
  • Rubbing or scratching the eyes often

If you notice any of these symptoms, it is recommended to consult with a veterinarian for proper diagnosis and treatment options.

What are the stages of cataracts in dogs?

The typical stages of cataract in dogs progression are categorized as incipient, immature, mature, and hypermature.

These stages describe the different levels of development and severity of the cataract condition in dogs.

1. Early cataracts in dogs

In the beginning your pet will begin to have blurred vision.

Or may also have double vision.

So it will be very difficult for the dog to distinguish people or objects that are at a considerable distance.

It will begin to develop more his sense of smell and hearing to be able to be guided.

2. Immature cataracts in dogs

Changes in pupil color is the first call for attention so don’t ignore it!

The color of the pupil may become bluish or whitish in color.

This is called mild cataracts, but be careful, because it can evolve over the years.

3. Mature cataracts in dogs

When cataracts are in their most advanced stage is

when we notice that our pet starts to bump into objects.

Get lost while walking or even when we call him he seems disoriented.

4. Hypermature cataracts in dogs

By this last point the cataract has reached its peak.

In other words, the pupil is totally white, which means it has reached blindness.

Regular veterinary examinations and monitoring are crucial for assessing the stage and determining appropriate treatment options.

Are cloudy eyes considered a symptom of cataracts?

Although many people assume that cloudy eyes are a clear symptom of cataracts, it does not occur in all cases.

It is very difficult to detect whether your dog has cataracts or not, since cloudy eyes are due to many other reasons that have nothing to do with cataracts, such as glaucoma or eye ulcer.

Therefore, it is important that you go to a veterinary specialist when you suspect some of these symptoms to have your dog examined and tested to determine the possible existence of cataracts or not.

Will cataracts blind your dog?

Cataracts have the potential to cause blindness in dogs if left untreated.

However, there is still hope for our little furry ones!

With the right treatment for prevention or simply to improve the symptoms your dog will be as good as new, so no more worries!

It depends on which stage of cataracts your dog is in


In this category the cataract is still in its weak point, that is, it is very mild.

It is not detected with the naked eye and does not cause visual impairment.


By this point the cataract has managed to cover more than 15% of the lens.

This means that it causes mild visual problems, although it can develop several layers in the lens.


This is when the cataract covers the entire lens, even making it impossible to see the retina during an eye exam.

By this point your dog will have a noticeable loss of vision and may lead to total loss of vision.

4.Hyper maturity:

This is the final stage, so it is too late to be treated, as blindness is inevitable.

It occurs when the lens becomes deformed, shrinks and wrinkles, causing inflammation.

What Can You Do When Your Dog Has Cataracts?

It is very likely that you will need to make changes in your home.

So that your dog can adapt in a better way and avoid excessive stress.

Cataracts can cause disorientation, confusion, stress or discouragement.

Fortunately, your dog can enjoy his other senses, which he will learn to develop much better.

However, boosting our pets with a little help is not a bad thing.

Your pet will thank you for it.

What measures do we recommend to take if your dog suffers from cataracts?

One of the senses that dogs develop even more when suffering from blindness.

The sense of smell
Touch and hearing

So placing several sensory signals around the house can facilitate their adaptation period.

Here are some simple examples that you can carry out to help your dog and accompany him in this process:

Make changes around the house

Change the position of the furniture if necessary so that he learns where each one is and thus avoids constant stumbling.

After that, minimize changes in the layout of your home to prevent confusion and accidents.

Inspect the pathways in your home to identify any sharp furniture corners or hazardous objects that your dog could potentially collide with.

Take necessary measures such as relocating or covering these items to ensure your dog’s safety in case of accidental impact.

Use scent markers

Fragrances of different smells in each room.

Your dog will quickly create a mental and olfactory map, enabling them to navigate their surroundings.

Introduce scented cues or markers to help your dog identify important areas, such as food and water bowls, their bed, or the door.

Use textured surfaces

Place different textured surfaces, like rugs or mats, to help your dog differentiate between rooms or areas.

Rugs of different textures in separate rooms and if your house has stairs you can also place them there.

A blanket or stuffed animal on your dog’s bed that has its own scent and is always located in one place.

So that when he wants to rest he knows where to go.

Cataract Surgery For Dogs

Surgical intervention for cataract treatment is the most common surgery.

However, this surgery is recommended only if your dog has severely impaired vision.

It can become a high-risk surgery if your dog appears to have glaucoma, dry eyes or inflammation.

In addition, this surgery can cause several pains in the wallet.

Since single eye surgery can cost you around $5,000 (and in fact, that’s just an estimate, it can cost even more).

And that’s not the worst part, but all the cost of post-operative care.

Since your dog will be in a warm, resting state after surgery, he should have the best attention and care.

Dog cataract eye drops lanosterol

Cataracts occur when the lens of the eye becomes cloudy, and surgical removal is typically the most effective way to restore vision.

If your dog’s cataracts are in the early stages or surgery is not a feasible option.

Your veterinarian will let you know, and may recommend the use of other more affordable treatments, such as lanosterol drops.

Lanosterol is a compound that has shown promising results in studies for dissolving cataracts in humans and animals.

The eye drops containing lanosterol are believed to help reduce the cloudiness of the lens and potentially improve vision.

What are Lanosterol Eye Drops?

Lanosterol eye drops are liquid eye drops that medical studies have shown to be effective in reducing, preventing or fighting cataracts.

Lanosterol is a naturally occurring steroid found in all animals. Studies in 2005 and 2016 and 2018 stated that the drops significantly reduced cataracts in dogs.

Since lanosterol is found in all animals, these drops are safe and functional in humans and any kind of animals.

It is for this reason that it began to have a reputation for progressive healing, due to its excellent effectiveness.

However, you must take into account that if your pet presents a type of cataract that is too advanced, lanosterol eye drops will not be able to have any effect.

These drops do not cure the condition, they only have the ability to reduce or prevent it.

What is the function of lanosterol eye drops?

What is the function of lanosterol eye drops?

When the drops are used, they release a small amount of lanosterol.

which acts to slow down the protein aggregations that cause the lens to become cloudy.

This helps to slow the progression of cataracts.

The development of lanosterol under enzyme catalysis results in the primary structure of the steroid. 14-Demethylation of lanosterol by CYP51 ultimately produces cholesterol.

Therapeutic effects of lanosterol drops

Its effect may vary depending on the severity of the cataract.

But with regular use lanosterol can gradually reduce the size of cataracts and prevent new ones from growing.

An official website of the United States government:

“Lanosterol showed a short-term and reliable reversal effect on reducing cataract severity in cortical cataract in the early stages.

Possibly due to the increase in the solubility of lens proteins and changes in the oxidative stress status.”

Does lanosterol cure cataracts in dogs?

Although they have the advantage of significantly reducing cataracts in dogs, some experts have very different opinions.

While there are varying opinions on its effectiveness, it cannot be definitively stated whether lanosterol eye drops can completely cure cataracts in dogs.

However, this does not mean that lanosterol eye drops are without potential benefits.

Even if they may not fully reverse cataract progression, they may still provide some advantages for your dog’s eye health.

Lanosterol eye drops could potentially help in reducing the severity of cataracts, slowing their progression, or improving overall eye condition.

Therefore, further research is needed to get to the bottom of it all.

Benefits of using lanosterol eye drops for canine cataracts

Although the complete elimination of canine cataracts with lanosterol eye drops is not currently achievable.

They can still provide benefits for your dog.

Lanosterol eye drops can be used as a preventive measure to reduce the risk of cataract formation in dogs that are more susceptible to the condition.

Furthermore, lanosterol eye drops can help slow down the progression of cataracts.

Lanosterol eye drops for dogs reviews

Although anecdotes should not replace scientific studies.

Many pet owners have reported positive experiences with lanosterol eye drops.

Some have observed brighter eyes in their dogs within a few weeks of use.

Considering these potential benefits.

There is no harm in trying lanosterol eye drops as a treatment for your dog’s cataracts.

What are the side effects of lanosterol eye drops in dogs?

Since lanosterol is naturally found in all animals, including dogs.

The use of lanosterol eye drops is considered safe and unlikely to cause any adverse reactions.

However, it is worth noting that some dogs may experience a temporary mild stinging sensation upon administration of the drops.

Should not be a cause for concern as the sting will disappear after a few moments.

Best dog cataract eye drops

Before using lanosterol eye drops on your dog, it’s important to consult with your veterinarian for proper guidance.

When selecting lanosterol eye drops, it’s essential to choose a reliable and effective product.

Not all lanosterol eye drops on the market may be effective.

To ensure the best results, it is recommended to use trusted and recommended lanosterol eye drops.

Such as our Advanced Lanosterol Solution + N-Acetylcarnosine.

This product is manufactured using advanced and high-quality automated processes, making it one of the top choices for lanosterol eye drops for your dog.

The dosage may vary according to the following factors:

  • The dog’s size

  • The cataract’s size

  • The cataract’s severity

Prior to administering the eye drops, it is crucial to carefully read the instruction guide and consult your veterinarian for proper guidance.

Final Thoughts

Lanosterol eye drops are a safe and effective treatment for your pets, so don’t worry.

Although surgery will always be the best option, lanosterol eye drops could still offer some relief and potentially prevent the formation of new cataracts.

To ensure the best results, it is recommended to use trusted and recommended lanosterol eye drops.

Such as our Advanced Lanosterol Solution + N-Acetylcarnosine.
