This guide, prepared by a veterinary ophthalmologist, covers the cost range for cataract surgery in dogs at different clinics, the ophthalmic examinations used to determine surgical eligibility, and key management points for each stage of the 4-week postoperative recovery period.

What Are Canine Cataracts? Why Surgery Is Essential

Canine cataracts are a progressive eye condition in which the lens inside the eye becomes cloudy, leading to a gradual decline in vision. Lens opacity progresses through four stages: incipient, immature, mature, and hypermature. The most critical factor is the timing of surgery. Performing phacoemulsification—removing the cataract and implanting an artificial lens—at a relatively early stage, before the lens hardens completely, significantly increases the likelihood of restoring vision. However, the actual success rate depends on retinal function and the presence of any complications. If treatment is delayed, complications such as lens-induced uveitis or secondary glaucoma may develop due to lens proteins, making vision recovery more difficult and increasing both surgical and treatment burdens.

Three Causes of Cataracts

Canine cataracts can be broadly categorized based on their causes and underlying mechanisms. - Hereditary cataracts: This is the most common cause, reported in over 90 breeds including Miniature Poodles, Bichon Frises, Labrador Retrievers, and Miniature Schnauzers. They typically progress in both eyes. - Age-related cataracts: These develop with age and may progress slowly, often alongside nuclear sclerosis, a common condition in senior dogs. - Diabetic cataracts: Diabetes is a leading systemic cause of cataracts, which tend to progress relatively quickly in both eyes. Other potential causes include trauma, electric shock, chronic uveitis, exposure to ultraviolet or ionizing radiation, and nutritional deficiencies.

Five Early Signs of Cataracts to Check at Home

The earlier it is detected, the higher the success rate of surgery. - Changes in pupil color: The center of the eye may appear bluish or milky white. - Difficulty seeing in the dark: Your pet may bump into furniture or walls in dimly lit rooms. - Hesitation on stairs or thresholds: Even in familiar surroundings, your pet may pause or seem unsure. - Reduced response to play: Your pet may struggle to follow a rolling ball. - Eye rubbing or redness: These could be early signs of uveitis, a potential complication.

These Signs Require Veterinary Ophthalmologic Care Within 24 Hours

If one eye suddenly becomes cloudy over just a few days, or if your pet frequently squints and shows increased redness and tearing, seek immediate veterinary ophthalmologic care. Leakage of lens proteins can lead to lens-induced uveitis or secondary (post-uveitic) glaucoma, causing a rapid rise in intraocular pressure that may result in vision loss within a short period. Secondary glaucoma can progress acutely, requiring prompt emergency intervention; sudden vision changes in diabetic dogs are particularly urgent.

Four Ophthalmic Examinations to Determine Surgical Eligibility

What matters most isn’t the cataract itself, but whether the retina is still healthy. - Slit-lamp examination: Assesses the degree of lens opacity and the condition of the posterior capsule. - Intraocular pressure measurement: Checks for concurrent glaucoma. - Electroretinogram (ERG): Measures retinal function—if results are abnormal, vision recovery after surgery is unlikely. - Ocular ultrasound: Detects retinal detachment or posterior capsule rupture behind the lens. All four tests must be passed before a surgery date can be scheduled.

Comparison of Cataract Surgery Costs by Clinic Type

Item	General Animal Hospital Ophthalmology	Specialized Ophthalmology Hospital	University Animal Hospital
Pre-operative comprehensive exam	KRW 200,000–400,000	KRW 400,000–600,000	KRW 300,000–500,000
Single-eye surgery (incl. anesthesia & hospitalization)	KRW 1.5–2.5 million	KRW 2.5–4 million	KRW 2–3.5 million
Simultaneous bilateral surgery	KRW 2.8–4.5 million	KRW 4.5–7 million	KRW 3.8–6 million
Premium intraocular lens add-on	Limited options	+KRW 300,000–600,000	+KRW 300,000–500,000
Post-operative regular checkup (per visit)	KRW 80,000–120,000	KRW 120,000–180,000	KRW 100,000–150,000

These are typical ranges as of May 2026. Actual costs may rise further depending on the presence of complications, surgical equipment (whether phacoemulsification is used), and the type of intraocular lens. For an accurate estimate, receive one directly from the hospital after reviewing the ERG test results.

Step-by-Step Guide to 4-Week Postoperative Recovery Management

The success of the surgery depends more on post-operative care than on the procedure itself. - Days 0–3: Hospitalization for monitoring intraocular pressure and inflammation, with eye drops administered every 2 hours. - Days 4–14: After discharge, wear an Elizabethan collar 24 hours a day. Use four types of eye drops—anti-inflammatory, antibiotic, mydriatic, and artificial tears—every 4 to 6 hours. - Weeks 2–4: Gradually reduce the frequency of eye drop administration and complete two follow-up ophthalmic examinations. Begin with short walks, and bathing is permitted after four weeks.

Home Care Points to Prevent Recurrence and Complications

The most common postoperative complications are posterior capsule opacification and increased intraocular pressure (secondary glaucoma). - Strict adherence to eye drop schedule: Set alarms to administer drops at the prescribed times—missing even one dose can allow inflammation to flare up again. - Prevent head trauma: Block off narrow spaces and stairs to avoid accidental bumps. - Prevent eye rubbing: The neck collar must be worn 24 hours a day for four weeks. - Keep all follow-up appointments: It is crucial to attend every scheduled check-up at one week, one month, three months, and six months post-surgery.

Additional Precautions by Breed and Underlying Conditions

Breed predisposed to hereditary cataracts, such as Poodles, Cocker Spaniels, and Bichon Frises, often develop the condition in both eyes. Therefore, after surgery on one eye, the other eye should be closely monitored, and additional surgery may be considered. In some breeds, there is a risk of secondary glaucoma after cataract surgery, making intraocular pressure monitoring particularly important. For diabetic dogs, it is advisable to schedule surgery only after blood sugar levels have been stably controlled, and insulin dosage adjustments may be necessary before and after the procedure. If underlying health conditions are present, a thorough assessment of the dog’s overall health is essential before anesthesia and surgery.

Frequently Asked Questions About Canine Cataract Surgery

What is the success rate of cataract surgery in dogs?

If surgery is performed at a relatively early stage, such as the immature or early mature phase, the likelihood of regaining vision is high. However, the prognosis worsens if retinal function has declined or if uveitis or glaucoma is present. Electroretinography (ERG) results are the most important indicator for predicting visual recovery.

If only one eye has cataracts, is it okay to operate on just that eye?

Hereditary and diabetic cataracts often progress in both eyes, so treating both simultaneously can be advantageous in terms of reducing anesthesia burden and overall cost. In cases of age-related cataracts affecting only one eye, surgery may be performed on that eye alone. A decision should be made by a veterinary ophthalmologist.

Is surgery possible for senior dogs (12 years and older)?

Anesthesia suitability is more important than age. If heart, kidney, and liver function tests are passed, surgery is possible even in older pets. When life expectancy is sufficient and anesthesia risk is low, the improvement in quality of life from restoring vision is significant.

Is it absolutely necessary to implant an artificial lens?

Even if cataracts are removed without an artificial lens, vision improves to some extent, but the pet will end up with hyperopia (farsightedness) due to poor focusing. Inserting an artificial lens restores vision close to normal. We generally recommend implanting an artificial lens, especially for pets with a longer life expectancy.

Will my pet’s vision remain stable for life after surgery?

After surgery, some pets may develop posterior capsule opacification. In such cases, vision can usually be restored relatively easily with a YAG laser procedure. However, if retinal detachment or glaucoma occurs, there is a risk of permanent vision loss, making lifelong regular check-ups essential.
