The Real Risks of Cataract Surgery — And How the Right Surgeon Changes Everything

Can You Go Blind From Cataract Surgery?

It's one of the first questions patients ask — and one of the most important. Before scheduling a consultation, before researching lenses, before anything else, many people need to know: is this surgery actually safe?

The honest answer is that yes, vision loss from cataract surgery is possible. In the rarest of cases, it is possible to lose an eye. That's not a comfortable thing to read, but it's the truth — and at Cohen Eye Institute, Dr. Ilan Cohen believes patients deserve a real answer, not a reassuring slogan.

What Dr. Cohen also believes, after more than twenty-five years and tens of thousands of surgeries, is that the risk patients fear most is not a fixed number. It is not the same for every patient, in every operating room, with every surgeon. And understanding that distinction is the most important thing anyone facing cataract surgery can know.

The Risks Are Real — Here's What They Are

Rather than minimizing the risks of cataract surgery, Dr. Cohen addresses them directly with every patient. Here is what the most serious complications actually look like.

• Endophthalmitis (Deep Eye Infection)

The most feared complication in cataract surgery is a deep infection inside the eye. Bacteria entering the eye's interior can multiply rapidly in the fluid that surrounds the retina — a chamber with almost no natural ability to fight back. Within a day or two, an eye can deteriorate from clear to painful and clouded. It is rare, but it is real, and it is the complication that keeps experienced surgeons vigilant.

• Suprachoroidal Hemorrhage (Severe Bleeding)

In extremely rare cases during surgery, a blood vessel beneath the retina can rupture, causing the eye to fill with blood while the patient is on the table. In its worst form, this can permanently damage vision.

• Posterior Capsule Rupture

The delicate bag that holds the natural lens in place is thinner than a soap bubble. If it tears during surgery, fragments of the cloudy lens can migrate to the back of the eye, triggering swelling, elevated pressure, and the need for a second procedure.

• Retinal Detachment

The light-sensing tissue at the back of the eye can, in some cases, peel away from its underlying layer — sometimes weeks after surgery appeared to go smoothly. Retinal detachment requires prompt treatment and can threaten vision if not addressed quickly.

These risks are real, and any surgeon who tells a patient otherwise is not being straight with them.

The Most Important Thing Almost Nobody Explains

The consent form a patient signs before cataract surgery lists statistical averages — averages drawn from surgeons at every level of experience, working in facilities of every kind. Those numbers do not represent any individual patient's actual risk.

A patient's real risk is shaped by who is operating on them, and what that surgeon does before, during, and after surgery to prevent complications from occurring. That is the variable that matters most, and it is a variable patients have real power over.

How Dr. Cohen Works to Push Every Risk Toward Zero

At Cohen Eye Institute, the work of preventing complications begins long before the patient reaches the operating room.

• Comprehensive Pre-Surgical Planning

Each eye is mapped using multiple cross-referencing imaging systems, because a single imprecise measurement carries its own risk. The retina is examined for weak spots. Conditions that make surgery more complex — a dense cataract, a small pupil, prior trauma or previous eye surgery — are identified ahead of time, so there are no surprises. In Dr. Cohen's experience, most complications are not bad luck. They are surprises that careful foresight would not have allowed.

• A Multi-Layered Approach to Infection Prevention

Infection is the enemy Dr. Cohen respects most, and his prevention protocol reflects that. Antibiotic drops begin three days before surgery. Sterile preparation is meticulous. Incisions are crafted to be self-sealing, minimizing any pathway for bacteria to enter the eye. Each preventive measure functions as one wall in a structure designed so that an infection would have to breach every single one.

• Gentle, Experience-Guided Technique in the Operating Room

During surgery, delicate structures are protected with a cushioning gel, and the technique used to break up and remove the cataract is designed to apply as little stress to the eye as possible — refined over years of high-volume practice. Perhaps the most important surgical skill of all, however, is knowing the exact moment to change the plan. When an eye behaves unexpectedly, it is experience — having seen that situation many times before — that keeps a deviation from becoming a complication.

What the Statistics Look Like in Experienced Hands

Every one of the complications described above is real. In experienced, careful hands, they are also extraordinarily rare.

Endophthalmitis — the infection that can threaten an eye — occurs in far fewer than one in a thousand surgeries, and even when it does occur, most eyes are saved with prompt treatment. Serious bleeding is rarer still. For the overwhelming majority of patients, cataract surgery is a procedure that takes only minutes, requires no overnight hospital stay, and produces results that feel remarkable: colors that appear brighter, faces and street signs coming into focus with a sharpness patients had forgotten was possible.

The most common thing patients say after surgery isn't that they were frightened. It's that they wish they had done it years earlier.

How to Choose the Right Cataract Surgeon

The fear of cataract surgery is not irrational — it's simply incomplete. The real risk isn't just whether vision loss is possible. The real risk is going through surgery with the wrong evaluation, the wrong preparation, or the wrong hands. And that is a risk patients can actively reduce.

Here are the questions worth asking at any cataract surgery consultation.

• How many cataract surgeries do you perform each year?

Surgical volume is one of the most well-studied predictors of safety in eye surgery. A surgeon who operates at high volume has encountered rare and difficult situations many times, and already knows how to manage them calmly.

• What is your posterior capsule rupture rate?

This is the most common serious intraoperative event in cataract surgery. An experienced surgeon will know their number and won't hesitate to share it.

• What is your infection rate?

Surgeons who track this metric take outcomes seriously. Those who have never considered it are communicating something important.

• How long have you been performing cataract surgery, and are you fellowship-trained?

Fellowship training in cornea and anterior segment surgery represents additional years of focused study in exactly the structures involved in cataract surgery.

• Are you comfortable with complex cases?

Dense cataracts, small pupils, eyes with prior trauma, eyes that have previously had LASIK — comfort with difficult presentations is a sign of genuine command of the procedure.

Signals to Look For — and Warning Signs to Heed

Beyond the consultation, there are things patients can observe and verify on their own.

Look for evidence that other physicians — particularly other eye doctors — trust this surgeon with their own vision. When medical professionals choose a surgeon for themselves, that is a form of validation no marketing can replicate.

Notice whether the practice uses more than one imaging device to measure the eye and cross-checks results. It's a quiet indicator of how seriously the team takes precision.

When reading patient reviews, look past comments about office friendliness and staff warmth. Look for what people say about the surgeon specifically — difficult cases handled well, complications addressed, patients cared for when things were not simple. That is the review that actually tells you something.

And confirm the basics: board certification, and a modern, well-equipped surgical facility.

Take caution if a surgeon:

1. Claims a perfect record or states they have never had a complication
2. Refuses to discuss risks at all
3. Rushes through the consultation
4. Recommends premium lenses before the eye has been fully examined

Honesty about risk is not a weakness in a surgeon. It is one of the clearest signs of real experience. The surgeons who have done the most tend to be the most humble about what can go wrong.

A Final Word on Technology

Every practice will showcase its newest laser, its most advanced imaging system, its latest intraocular lens technology. These tools can be genuinely valuable. But the newest machine in inexperienced hands is far more dangerous than proven technique in experienced ones. The machine does not perform the surgery. The surgeon does. It always comes back to the hands.
