Cataract Surgery Blindness: Ophthalmologic Malpractice in NY

Excerpt: Cataract surgery is one of the most common procedures in the US — but when errors occur, the result can be permanent blindness. This guide explains cataract surgery malpractice in New York.

Cataract Surgery: Common but Not Without Risk

Cataract surgery is one of the most frequently performed surgical procedures in the United States, with over 3 million operations performed each year. During cataract surgery, the clouded natural lens of the eye is removed and replaced with an artificial intraocular lens (IOL).

While cataract surgery is generally safe — with a success rate exceeding 95% — complications can and do occur. When they result from medical negligence, the consequences can be devastating: permanent vision loss, blindness, loss of the eye itself, or the need for additional surgery.

If you or a loved one suffered vision loss after cataract surgery, this guide explains when it may be medical negligence.

Common Complications of Cataract Surgery

1. Endophthalmitis

Endophthalmitis is a severe infection inside the eye. It is one of the most feared complications of cataract surgery. Symptoms include:

• Severe eye pain
• Decreased vision
• Redness
• Swelling
• Discharge

Endophthalmitis can cause permanent vision loss if not diagnosed and treated within hours. Treatment involves:

• Intravitreal antibiotics — Antibiotics injected into the eye
• Vitrectomy — Surgical removal of the infected vitreous

When Endophthalmitis Is Negligence

• Failure to use sterile technique — Causing the infection
• Failure to recognize symptoms promptly — Delaying treatment
• Failure to administer appropriate antibiotics — Inadequate treatment
• Delay in referral to a retina specialist — If treatment was beyond the surgeon's capability

2. Posterior Capsule Rupture (PCR)

During cataract surgery, the surgeon removes the clouded lens but leaves the posterior capsule — the back of the lens's outer membrane — intact to support the IOL. If the posterior capsule ruptures, the IOL cannot be properly placed, and the vitreous gel can prolapse into the anterior chamber.

PCR can lead to:

• Retinal detachment — The retina peels away from the back of the eye
• Cystoid macular edema (CME) — Swelling in the center of the retina
• Dislocation of lens fragments — Into the vitreous cavity
• Need for additional surgery — To repair the damage

When PCR Is Negligence

• Excessive force during phacoemulsification or IOL insertion
• Improper technique — Causing the capsule to rupture
• Failure to recognize the rupture — And manage it appropriately
• Failure to refer to a retina specialist — For fragments that fell into the vitreous

3. Retinal Detachment

Retinal detachment is a separation of the retina from the back of the eye. It can occur as a complication of cataract surgery — particularly after posterior capsule rupture. Symptoms include:

• Flashes of light
• Floaters
• A curtain or shadow over the visual field

Retinal detachment is a surgical emergency. Delay in treatment can cause permanent blindness.

4. Corneal Edema

Corneal edema is swelling of the cornea that can occur after cataract surgery, particularly if the surgery was difficult or prolonged. While mild edema often resolves, severe or persistent edema may require a corneal transplant.

5. Wrong IOL Power

The intraocular lens (IOL) must be correctly calculated to provide the appropriate refractive power. If the IOL power is miscalculated — or if the wrong IOL is implanted — the patient may have significant refractive error requiring glasses, contact lenses, or additional surgery.

6. Suprachoroidal Hemorrhage

Suprachoroidal hemorrhage is bleeding between the choroid and sclera. It is a rare but catastrophic complication that can cause expulsive hemorrhage (the eye bleeds outward) and permanent vision loss.

When Is a Cataract Surgery Complication Malpractice?

Not every complication is negligence. However, the following may constitute malpractice:

1. Failure to Obtain Proper Biometry

The IOL power calculation requires accurate biometry — measurements of the eye's axial length and corneal curvature. If these measurements were not obtained, were obtained incorrectly, or were not verified, the resulting wrong IOL power may be negligence.

2. Improper Surgical Technique

If the surgeon used excessive force, improper technique, or failed to follow the standard surgical protocol, complications like PCR or corneal damage may be negligent.

3. Failure to Recognize and Manage Complications

If a complication (such as PCR or endophthalmitis) occurred, the surgeon must recognize it promptly and take appropriate action — including referral to a specialist if needed.

4. Failure to Provide Appropriate Follow-Up

The surgeon must provide appropriate post-operative monitoring and instructions. Failure to see the patient for follow-up, or failure to respond to symptoms of complications, may be negligence.

5. Operating on the Wrong Eye

Wrong-eye surgery is a "never event" — it should never happen with proper protocols.

Proving a Cataract Surgery Malpractice Claim

Key Evidence

• Pre-operative records — Including biometry and IOL calculations
• Operative report — Documenting the surgical technique and complications
• Post-operative records — Documenting follow-up and any complications
• OCT and imaging — Showing retinal or corneal damage
• Culture results — If endophthalmitis occurred
• Referral records — If the patient was referred to a retina or cornea specialist

Expert Witnesses

Cataract surgery cases require testimony from:

• An ophthalmologist — On the standard of care for cataract surgery
• A retina specialist — If retinal detachment or vitreous complications occurred
• A cornea specialist — If corneal damage occurred
• A neuro-ophthalmologist — If optic nerve injury occurred

Statute of Limitations

Under CPLR 214-a, the statute of limitations is 2.5 years from the date of the malpractice. The continuous treatment doctrine may extend this if you continued receiving treatment from the same surgeon.

Frequently Asked Questions

Can cataract surgery cause blindness?

Yes. While cataract surgery is generally safe, complications such as endophthalmitis, retinal detachment, or suprachoroidal hemorrhage can cause permanent vision loss or blindness.

What is endophthalmitis?

Endophthalmitis is a severe infection inside the eye that can occur after cataract surgery. It is a medical emergency that requires immediate treatment with intravitreal antibiotics. Delay in treatment can cause permanent blindness.

What is posterior capsule rupture?

Posterior capsule rupture (PCR) is a tear in the membrane that supports the intraocular lens. It can lead to retinal detachment, lens fragment dislocation, and the need for additional surgery. While PCR can be a known risk, it may be caused by improper surgical technique.

Can I sue for wrong IOL power?

Yes. If the IOL power was miscalculated due to improper biometry, or if the wrong IOL was implanted, this may constitute negligence — particularly if it requires additional surgery or causes significant refractive error.

How long do I have to file a cataract surgery malpractice claim?

Under CPLR 214-a, the deadline is generally 2.5 years from the date of the malpractice. The continuous treatment doctrine may extend this.
