Cataract surgery on a cat runs $1,850 to $3,350 for one eye in the US, 1,470 to 2,700 GBP in the UK, and 5,000 to 10,800 CNY in China, and that band is 3 priced items plus 4 rechecks rather than a single fee. The items are the eye workup, the anesthesia block, and the removal of the lens itself. What turns a 1,850 quote into a 4,000 one is rarely the surgery: it is the state of the retina behind the lens, and whether 1 eye or 2 go on the table.
Three items, three currency columns
The figures below are referral-hospital ranges for a cat with a mature cataract and no other eye disease. Every row is a separate line on the estimate, and the shape of that estimate is the same one used for entropion surgery or joint surgery: 1 workup, 1 anesthesia block, 1 procedure, then visits.
| Item | What it covers | US (USD) | UK (GBP) | China (CNY) |
|---|---|---|---|---|
| 1: eye workup | B-scan ultrasound, ERG, pressure, tear test, blood panel | 250-450 | 180-350 | 500-1,500 |
| 2: anesthesia | 45-90 minutes, IV fluids, monitoring, warming | 350-600 | 280-500 | 800-2,000 |
| 3: phaco, 1 eye | 30-50 minutes, lens removal, foldable implant | 1,100-2,000 | 900-1,600 | 3,500-6,500 |
| 3: phaco, both eyes | 2 eyes, 60-100 minutes of table time | 1,900-3,500 | 1,500-2,800 | 6,000-11,000 |
| Rechecks, 4 visits | Day 1, day 7, week 4, month 3 | 150-300 | 110-250 | 200-800 |
Converted at 7.2 CNY to the dollar, the same 3 items and 4 visits cost 2 to 3 times more in the US or the UK than in China, and the gap is widest on the surgery row rather than on the workup. The columns move for a simple reason: the implant, the anesthesia time, and the visit count are counted the same way in all 3 places, but the hourly rate behind them is not.
Item 1: the 250 to 450 workup that can cancel the operation
Three tests carry the decision. A B-scan ultrasound takes 10 to 15 minutes and shows whether the retina is still attached; a detached retina behind a mature cataract is a reason to stop, not to operate. An electroretinogram, run under light sedation, measures whether the retina answers light at all, and a flat trace means a lens swap cannot restore sight. Pressure and tear readings add 5 minutes and rule out the 2 conditions that make a quiet eye worse after surgery. Bloodwork for a cat over 8 years old adds 60 to 120 to the same visit.
Spending 250 to 450 here protects the 1,100 to 2,000 behind it. An owner who skips it and operates on a retina that was already blind pays for a 2,000 procedure and takes home a cat that still cannot see.
Item 2: 45 to 90 minutes under anesthesia
One eye is 30 to 50 minutes on the table, 2 eyes are 60 to 100, and 15 to 20 minutes of preparation and recovery sit on top, so the anesthesia block bills at 350 to 600 in the US. Most practices place an IV catheter, run fluids at 5 to 10 mL per kg per hour, and record heart rate, blood pressure, and end-tidal gas every 5 minutes. A cat with a heart murmur or a kidney value out of range may need a cardiology clearance first, which is another 100 to 250 and 3 to 7 days of waiting.
Item 3: phacoemulsification, or removing the whole lens
Phacoemulsification breaks the lens up through a 2 to 3 mm incision and leaves the capsule standing, so a foldable implant can sit inside it. The machine behind that sentence costs more than most general practices will ever spend on equipment, which is why the row is 1,100 to 2,000 rather than 400. Whole-lens removal, used when the lens has already slipped out of position, takes 20 to 30 minutes and is 200 to 500 cheaper, but the eye comes out of it with no implant and more inflammation in the first 2 weeks. Operating the second eye 2 to 4 weeks after the first is common; doing both at once saves 1 anesthesia and doubles the recovery to watch.
Day case, or 1 night in the building
Most cats go home 2 to 4 hours after they wake, with a cone and 3 days of quiet. A hospital that keeps cats overnight charges 80 to 200 for the night, and a diabetic cat is often held 24 hours so glucose can be read 4 to 6 times. That single line adds 150 to 400 and is the most common reason 2 quotes for the same surgery differ by 300.
The 4 rechecks already inside the price
Eye pressure is read at day 1, day 7, week 4, and month 3, because the main risk in the first 6 weeks is a pressure spike that a cat cannot tell you about. Each visit is 30 to 60 in the US and takes 10 to 15 minutes. Dropping the week 4 visit saves 50 and is how some eyes are lost at week 6 to a problem that was visible at week 4.
What adds 1,000 or more to a quote
- A detached retina on ultrasound: surgery is usually declined, and the 250 to 450 workup becomes the whole bill.
- Lens-induced uveitis: 2 to 4 weeks of treatment before the table, plus 100 to 300 in extra visits.
- Both eyes: 60 to 100% more on the surgery row, and 3 to 4 extra rechecks.
- An implant: 150 to 400 on top, and not every eye qualifies.
- A second procedure for a complication inside the first 30 days: 500 to 1,500.
Five steps before you book
- Ask whether the quote includes the electroretinogram and the ultrasound, not only the surgery.
- Ask how many rechecks sit inside the number. Four is normal; one is not.
- Get the second-eye price in writing, because roughly 1 in 3 cats have both lenses affected by the time of diagnosis.
- Compare the total against our cost calculator before you call a third hospital.
- If a quote under 900 appears, ask what was left out, since anesthesia alone rarely lands under 280.

Frequently asked
Is cataract surgery for a cat worth the cost?
It depends on what the workup shows. If the electroretinogram and the B-scan are normal, most ophthalmologists report useful vision returning within 2 to 4 weeks, and the 1,850 to 3,350 buys 5 to 8 more years of sight in a cat that lives indoors. If the retina is detached or unresponsive, the same money buys pain relief at best, so the 250 to 450 workup is the part that decides whether the rest is worth spending.
Why is the second eye cheaper or more expensive?
Both eyes at once usually cost 60 to 100% more on the surgery line, not 100% more on the total, because the workup and the anesthesia induction are shared. Staging the eyes 2 to 4 weeks apart means paying 2 anesthesia blocks of 350 to 600 each, but it keeps 1 eye able to see while the other heals, which matters for a cat navigating stairs in the first 10 days.
Does pet insurance cover the 5,000 to 10,800 CNY bill?
Most accident-and-illness policies cover it if the cataract was not noted before the policy started, and many reimburse 70 to 90% after a deductible of 100 to 300. Claims usually need the pre-op workup report, the invoice with item lines, and a note that the condition was not pre-existing, so ask the hospital for an itemized bill rather than a single total.
