How is cataract surgery performed under anesthesia?

Cataract surgery is one of the most common eye surgeries, especially among elderly patients. However, anesthesia remains one of the main concerns for many patients before undergoing the procedure, especially when they wonder whether they will feel pain or need general anesthesia.

In fact, anesthesia for cataract surgery is simple and safe in most cases. It is usually performed using anesthetic eye drops or local anesthesia, helping the patient go through the surgery comfortably and with reassurance.

In this article, we will explain how anesthesia is used during cataract surgery, whether the patient feels pain during the procedure, the difference between topical, local, and general anesthesia, and the most important instructions to know before and after surgery. We will also refer to the main symptoms of cataracts that may lead the patient to consider surgical treatment.

How Is Cataract Surgery Anesthetized?

Anesthesia for cataract surgery is one of the most common questions patients ask before the procedure, because many people feel anxious about the idea of surgery or wonder: Will I be awake? Will I feel pain? Does cataract surgery require general anesthesia?

In most cases, cataract surgery is performed under topical or local anesthesia, without the need for general anesthesia. The patient remains awake during the procedure but does not feel pain. They may see some lights, shadows, or slight movement, but they do not see the details of the surgery.

The choice of anesthesia depends on the condition of the eye, the patient’s ability to cooperate, the presence of severe anxiety, the patient’s age, and their general health condition. Therefore, there is no single type of anesthesia that suits all patients.

Is There Anesthesia in Cataract Surgery?

Yes, anesthesia is used in cataract surgery, but in most cases it is not general anesthesia. The goal of anesthesia is to keep the eye comfortable during surgery and prevent the patient from feeling pain.

The procedure is usually performed using anesthetic drops applied to the surface of the eye. In some cases, local anesthesia may be added around the eye. General anesthesia is used only in specific cases, such as children or some patients who cannot cooperate or remain still during the procedure.

Types of Anesthesia in Cataract Surgery

The types of anesthesia used in cataract surgery vary according to the patient’s condition and the doctor’s assessment. The most commonly used types include:

Topical Anesthesia With Eye Drops

Topical anesthesia with eye drops is one of the most commonly used types of anesthesia in modern cataract surgery. Anesthetic drops are placed on the surface of the eye before and during the procedure, reducing pain sensation and making the surgery more comfortable for the patient.

With this type of anesthesia, the patient remains awake and can hear the doctor’s instructions, but does not feel pain. They may only feel light touch, slight pressure, or see the microscope light during the procedure.

Topical anesthesia is suitable for many patients, especially if the patient is calm, able to keep the eye steady, and can follow simple instructions during surgery.

Local Anesthesia Around the Eye

In some cases, the doctor may need to use local anesthesia around the eye. This is done by injecting a local anesthetic in the area around the eye or under the surrounding membrane, depending on the method suitable for the case.

This type of anesthesia helps significantly reduce pain sensation and may also help reduce eye movement during the procedure. Therefore, it may be used in cases that require greater eye stability or when the doctor believes that anesthetic drops alone may not be enough.

The patient remains awake with this type of anesthesia as well, but does not feel pain during the surgery.

General Anesthesia

General anesthesia is not usually used for cataract surgery in adults, but it may be suitable in special cases, such as:

• Children.

• Some patients with special needs.

• Patients who are unable to remain still or cooperate during surgery.

• Severe anxiety cases that cannot be controlled with simple sedation.

• Certain medical or surgical cases determined by the surgeon and anesthesiologist.

With general anesthesia, the patient is completely asleep during the procedure, and this is done under the supervision of an anesthesiologist.

Does the Patient Feel Pain During Cataract Surgery?

In most cases, the patient does not feel pain during cataract surgery. They may feel slight pressure, a mild sensation of touch on the eye, or see lights and colors during the procedure, but pain is not expected with proper anesthesia.

If the patient feels any discomfort during the procedure, they can inform the doctor, and it will be managed immediately. That is why clear communication between the doctor and the patient before surgery is important, so the patient knows what to expect during the procedure.

Does the Patient Need a Sedative Before Cataract Surgery?

Some patients may need a mild sedative before or during the procedure, especially if they feel tense or very anxious about surgery.

A sedative does not mean general anesthesia. It simply helps the patient relax during the procedure. The decision to use it is based on the assessment of the doctor and anesthesiologist, the patient’s health condition, the medications they take, and their level of anxiety.

How Is Cataract Surgery Performed After Anesthesia?

After the eye is anesthetized, the steps of cataract surgery and lens implantation usually proceed as follows:

• The doctor makes a very small incision in the cornea.

• The cloudy lens is broken up using a phacoemulsification device with ultrasound waves.

• The pieces of the cloudy lens are removed from inside the eye.

• A clear artificial intraocular lens is implanted inside the eye in place of the natural lens.

• The small incision usually does not need stitches, as it heals on its own.

The procedure usually takes a short time, and the patient often leaves the center or hospital on the same day after being checked.

Can Cataract Surgery Be Performed With Laser?

Femto laser may be used in some steps of cataract surgery, such as creating precise incisions or assisting in lens fragmentation.

However, phacoemulsification with ultrasound remains one of the most commonly used methods in modern cataract surgery. Not every patient needs femto laser, as the choice depends on the condition of the eye, the type of cataract, test results, and the surgeon’s assessment.

The most important point is choosing the method that best suits the patient’s condition, along with selecting the appropriate artificial lens for their visual needs.

Is Anesthesia in Cataract Surgery Safe?

Yes, anesthesia for cataract surgery is safe in most cases, especially because it is usually topical or local anesthesia, not general anesthesia.

However, like any medical procedure, the patient must be evaluated before surgery to choose the most suitable anesthesia method.

The patient should inform the doctor before surgery if they have chronic conditions such as heart disease, high blood pressure, diabetes, or if they take blood thinners, have allergies to certain medications, or have previously experienced a problem with anesthesia.

Before Cataract Surgery: What Should You Tell Your Doctor?

Before cataract surgery, it is important to tell your doctor about all details that may affect anesthesia or the procedure, including:

• The medications you take, especially blood thinners.

• Chronic diseases such as diabetes, high blood pressure, heart disease, or breathing problems.

• Any allergy to certain medications or eye drops.

• Any previous eye surgeries.

• If you cannot lie on your back.

• If you have tremors or difficulty staying still.

• If you feel very anxious about the procedure.

• If you have previously had any problem with anesthesia during another surgery.

This information helps the doctor choose the most suitable type of anesthesia and reduce any potential risks.

Does Cataract Surgery Require General Anesthesia?

No, in most cases cataract surgery does not require general anesthesia. Most procedures are performed using topical anesthetic drops or local anesthesia around the eye, and the patient remains awake without pain.

General anesthesia is used only in special cases, such as children, some patients with special needs, or patients who cannot cooperate or remain still during the procedure.

After Surgery: Does the Anesthesia Wear Off Quickly?

Yes, the effect of anesthetic eye drops usually wears off shortly after the procedure. The patient may feel mild burning, a foreign body sensation, or tearing during the first few hours, and this is usually normal.

After surgery, the patient must use the prescribed eye drops carefully, avoid rubbing the eye, attend follow-up appointments with the doctor to ensure eye safety and stability of the implanted lens, and follow the precautions after cataract surgery according to the doctor’s instructions.

Can Cataracts Come Back After Surgery?

After the cloudy natural lens is removed and replaced with an artificial lens, cataracts do not return in the natural lens because it has already been removed.

However, in some patients, clouding may occur behind the artificial lens after months or years. This is a different and relatively common condition. It is usually treated with a simple laser session in the clinic called YAG laser capsulotomy if the patient needs it.

Cost of Cataract Surgery and Whether It Differs According to Anesthesia

Cataract Surgery Cost and Does It Vary According to Anesthesia?

The cost of cataract surgery in Egypt starts from EGP 19,500 per eye, including phaco cataract surgery with a foldable intraocular lens. The cost may vary depending on the type of lens used, the eye condition, and the required examinations. Some advanced lenses, such as trifocal or EDOF lenses, may cost up to EGP 66,000 per eye.

Cataract surgery cost does not depend only on the type of anesthesia, but is affected by several factors, including:

• The type of implanted intraocular lens.
• The eye condition and the complexity of the procedure.
• The examinations required before surgery.
• The surgical technique used.
• The operating room equipment and sterilization standards.
• The surgeon’s experience and post-operative follow-up.
• The patient’s need for additional anesthesia or a special anesthesia assessment in some cases.

Therefore, the cost of cataract surgery is accurately determined after examination, not only based on the type of anesthesia.

Important note: All mentioned prices are estimated starting prices and may vary according to each patient’s condition. The final cost is only determined after consultation and medical examination.

Conclusion

Anesthesia for cataract surgery is simple and safe in most cases. It is usually performed using anesthetic eye drops or local anesthesia around the eye.

The patient is usually awake during the procedure but does not feel pain. They may only see lights or slight movement without seeing the details of the surgery.

General anesthesia is not the usual option in cataract surgery for adults. It is used only in special cases such as children, patients with special needs, or those who cannot cooperate during surgery.

Choosing the right type of anesthesia is done after a complete assessment of the case. The goal is always to perform the procedure with the highest possible level of comfort and safety for the patient.
