Who Invented Cataract Surgery?

When Was Cataract Surgery Invented?

The History of Eye Surgery

Eye surgery has been around for centuries, with ancient civilizations such as the Egyptians and Greeks performing crude procedures to treat eye conditions. These surgeries were often more dangerous than the diseases they were attempting to cure, due to the lack of knowledge about anatomy and the absence of modern surgical tools.During the Middle Ages, Arab physicians developed new techniques for eye surgery, including the use of retractors and probes to remove cataracts. However, these procedures were still very risky, with many patients suffering from infections or even blindness as a result.

The Earliest Recorded Cataract Surgery

The first recorded instance of cataract surgery took place in India in the 5th century BCE. The surgeon, Susruta, used a curved needle to push the clouded lens of the eye out of the way and then removed it with a spatula. He then allowed the eye to heal, leaving the patient with improved vision.This procedure became known as couching, and it remained the standard method for cataract surgery for centuries. However, it had a number of drawbacks. It only improved distance vision, leaving patients with blurry near vision, and it often caused other complications such as glaucoma or infection.During the 18th and 19th centuries, new surgical techniques were developed, including extracapsular cataract extraction (ECCE) and intracapsular cataract extraction (ICCE). These techniques involved removing the entire lens of the eye and replacing it with an artificial lens.

Modern Advancements

In the 20th century, cataract surgery underwent a revolution with the introduction of new technology and techniques. Small-incision cataract surgery (SICS) allowed surgeons to remove the cataract through a tiny incision, resulting in less trauma to the eye and quicker recovery times.In the 1960s, an American ophthalmologist named Charles Kelman developed phacoemulsification, a technique that involved using ultrasonic waves to break up the cataract into tiny fragments, which could then be removed through a small incision. This method was less invasive than previous techniques and allowed for a faster recovery time.Today, cataract surgery has reached new heights with the advent of laser-assisted cataract surgery (LACS). This technique uses a laser to make precise incisions and soften the cataract, allowing for easier removal.In conclusion, cataract surgery has a long and storied history, with new techniques and technologies constantly being developed to improve the safety and effectiveness of the procedure. Whether it is performed using the ancient technique of couching or the cutting-edge technology of LACS, cataract surgery remains one of the most widely performed surgical procedures in the world today, restoring the vision and quality of life of millions of patients every year.

When Was Cataract Surgery Invented?

Cataract surgery is a medical procedure that involves the removal of the natural lens of the eye when it becomes cloudy or opaque. This condition, called cataract, is a common eye problem that affects millions of people worldwide. Fortunately, cataract surgery has come a long way since its invention over 2,000 years ago.

Types of Cataract Surgery

Phacoemulsification Surgery

Phacoemulsification is a minimally invasive type of cataract surgery that uses ultrasound waves to break the lens into tiny pieces that can be easily removed from the eye. The procedure is performed through a small incision in the cornea using a phacoemulsification probe that emits ultrasonic waves to liquefy the lens material. The cloudy lens is then aspirated out of the eye through the same incision using a suction catheter.

This procedure has become the most common type of cataract surgery worldwide due to its many advantages. Phacoemulsification is generally safer, faster, and requires less downtime compared to traditional cataract surgery. Patients can usually return to their usual activities within a day or two after the procedure.

Extracapsular Cataract Surgery

Extracapsular cataract surgery is a more traditional type of cataract surgery that involves removing the cloudy lens as a single unit through a larger incision in the cornea. During this procedure, the surgeon removes the anterior capsule of the lens and manual dissects the cloudy lens out of the eye using forceps. The remaining posterior capsule of the natural lens is left intact and an intraocular lens (IOL) is then implanted into the eye to replace the natural lens.

Extracapsular cataract surgery is usually performed under local anesthesia and requires several sutures to close the incision. The recovery process is longer compared to phacoemulsification and patients may need to avoid strenuous activities for several weeks after the procedure.

Intracapsular Cataract Surgery

Intracapsular cataract surgery is a rare type of cataract surgery where the entire lens and capsule are removed together. During this procedure, the surgeon makes a large incision in the cornea and removes the cloudy lens and the entire capsule around it. The removal of the capsule requires a larger incision, which can lead to higher risks of complications and a longer healing time.

With the invention of new surgical techniques and technology over the centuries, cataract surgery has evolved into a safe and effective procedure that can improve vision and quality of life for many people. Today, cataract surgery is one of the most commonly performed surgical procedures in the world, with millions of surgeries performed every year.

Cataract Surgery: A Historical Overview

Cataract surgery has come a long way since its early days. Today, it is one of the most commonly performed surgeries in the US. However, this was not always the case. In this article, we will take a closer look at when cataract surgery was invented and how it has evolved over time.

The Early Days of Cataract Surgery

It is believed that cataract surgery was first performed in ancient India around 800 BCE. This involved a procedure known as couching, where a sharp instrument was used to push the cloudy lens aside and out of the visual axis. While this technique was successful in restoring sight, it was not without risks. Complications such as infection and damage to the eye were common.

Over the centuries that followed, various other techniques were developed to remove cataracts. These included suction, use of a sharp needle to puncture the eye and suck out the cloudy lens, and placing a heated needle through the sclera to dissolve the cataract. However, all these procedures were fraught with numerous risks.

Modern Cataract Surgery

It was not until the mid-20th century that modern cataract surgery was developed. In 1949, Sir Harold Ridley, an ophthalmologist from the UK, noticed that pilots who had been hit by shattered windscreens during World War II did not suffer adverse reactions when tiny fragments of plastic entered their eyes. This led him to develop the idea of intraocular lens implants, or IOLs.

With the invention of IOLs, cataract surgery was revolutionized. Instead of removing the diseased lens and leaving patients with thick eyeglasses or contact lenses, surgeons could now insert an artificial lens into the eye, restoring vision more effectively than ever before.

Preparing for Cataract Surgery

Pre-Operative Testing

Before cataract surgery, your surgeon will perform a number of tests to determine the extent of the cataract and assess your overall eye health. These tests include measuring the curvature of your cornea, determining the shape and size of your eye, and testing your visual acuity. Your surgeon may also perform imaging tests such as ultrasound or optical coherence tomography (OCT) to get a more detailed view of the inside of your eye.

To prepare for pre-op testing, your doctor may ask you to avoid wearing contact lenses for several days before your appointment. If you currently wear glasses, be sure to bring them with you to the testing.

Medications to Avoid

Before cataract surgery, you will need to stop taking certain medications and supplements that can increase the risk of bleeding or interfere with anesthesia. These include blood thinners such as aspirin and warfarin, nonsteroidal anti-inflammatory drugs (NSAIDs), and certain herbal supplements such as ginkgo biloba and garlic. Your surgeon will give you a complete list of medications and supplements to avoid, and you should follow these instructions carefully to ensure a safe and successful surgery.

Pre-Operative Instructions

Your surgeon or healthcare provider will give you instructions to follow before your cataract surgery. These may include fasting for a certain amount of time before the surgery, stopping certain medications, and arranging for transportation to and from the surgical center. You may also be asked to use prescription eye drops for several days before the surgery to minimize the risk of infection. Be sure to follow these instructions carefully to avoid any complications and ensure a smooth recovery.


Over the centuries, cataract surgery has come a long way. From early methods involving sharp needles and heated instruments to the invention of IOLs, modern cataract surgery has become safer and more effective. Pre-op testing, medication changes and pre-operative instructions are all essential steps in ensuring a successful and comfortable cataract surgery experience. With proper preparation and a little patience, cataract surgery can restore your vision and allow you to enjoy the world around you.

When Was Cataract Surgery Invented?

Cataract surgery is a procedure that involves removing the cloudy lens of the eye and replacing it with an artificial lens. It is one of the most commonly performed surgeries in the world and has been helping people improve their vision for centuries.

The history of cataract surgery dates back to ancient times when people used a needle to pierce the eye and then push the cloudy lens out of the way to make the vision clearer. This method was risky and often led to infection, blindness, or even death.

In the 18th century, Jacques Daviel, a French ophthalmologist, developed a safer method for cataract surgery. He used a curved needle to puncture the eye and then pushed the lens toward the back of the eye where it could be absorbed.

In the 20th century, cataract surgery became more advanced with the introduction of new technologies such as the use of microscopes, intraocular lenses, and phacoemulsification.

Phacoemulsification is a technique that uses ultrasound to break up the hard center of the lens into small pieces, which are then suctioned out through a tiny incision. This method has revolutionized cataract surgery and has made it more efficient and safer.

Benefits of Cataract Surgery

Cataract surgery is typically performed on an outpatient basis, which means that the patient can go home the same day. The recovery time is relatively short, and most people can resume their normal activities within a few days.

Cataract surgery has numerous benefits, such as improving vision, reducing glare, and enhancing the quality of life. It can also help to prevent falls, which are a common cause of injury in older adults with vision loss due to cataracts.

In addition to these benefits, cataract surgery has been shown to improve overall well-being, including improving mood, reducing anxiety, and enhancing social interactions.

What to Expect During Cataract Surgery

Cataract surgery is a relatively straightforward procedure, but it can be intimidating if you don't know what to expect. Here is a step-by-step guide of what happens on the day of surgery:

Day of Surgery

When you arrive at the surgery center or hospital, you will be checked in and asked to change into a hospital gown. You will then undergo a series of preoperative tests, including blood work, an electrocardiogram, and a physical exam. You will also be given eye drops to dilate your pupils, which will help your surgeon see the lens more clearly.

Before the surgery begins, you will be given either local or general anesthesia, depending on your preference and your surgeon's recommendation. Local anesthesia involves numbing only the eye being operated on, while general anesthesia will put you to sleep during the procedure.

Your surgeon will then make a small incision in the cornea and use a special tool to break up the cloudy lens. They will then remove the pieces of the lens and insert a new, clear intraocular lens in its place. The incision will be closed with a tiny stitch or glue.

The procedure typically takes less than an hour to complete, and you will be able to go home the same day. Your surgeon will give you specific instructions on how to care for your eye during the recovery period.

Anesthesia Used

There are several types of anesthesia that can be used during cataract surgery, including:

  • Local anesthesia: This involves numbing only the eye being operated on using eye drops or an injection around the eye. You will be awake during the procedure, but you will not feel any pain.
  • Topical anesthesia: This involves applying numbing eye drops to the surface of the eye. It is often used in combination with local anesthesia.
  • General anesthesia: This involves putting you to sleep during the procedure using medications administered through an IV.

Your surgeon will discuss the pros and cons of each type of anesthesia with you and help you choose the best option for your needs.

Length of Procedure

Cataract surgery typically takes less than an hour to complete, but the exact length of the procedure can vary depending on several factors, including:

  • The severity of the cataract
  • The technique used
  • The type of anesthesia used
  • Whether any complications arise during the surgery

Your surgeon will give you an estimate of the length of the procedure before the surgery so that you can plan accordingly.

In conclusion, cataract surgery has a long and rich history, and it has evolved into a safe and effective procedure that can improve the quality of life for millions of people worldwide. If you are considering cataract surgery, talk to your eye doctor to learn more about the benefits, risks, and options available to you.

When was Cataract Surgery Invented?

In ancient times, people believed that cataract, a clouding of the eye's natural lens, was caused by the wrath of gods or demons. They thought the only cure was to sacrifice an animal or pray for divine intervention. However, as human knowledge and medical technology advanced, people began to search for more effective cures. So, when was cataract surgery invented, and how has it evolved over the centuries?

Early Cataract Surgery Techniques

Cataract surgery originated in India around 6th century BCE. Susruta, an Indian physician and surgeon, described a technique called "couching" in his book Susruta Samhita, in which he used a sharp instrument to push the cloudy lens into the vitreous cavity. The lens would then fall to the bottom of the eye, where it would no longer obstruct vision. Unfortunately, the procedure also carried the risk of complications, such as retinal detachment, hyphema, and infection.In the 10th century, the Arab physician Al-Zahrawi introduced a modified couching technique called "needling," where a needle was used to puncture the lens and break it into small pieces. However, it was still an invasive and risky procedure that often led to blindness and other severe complications.

Modern Cataract Surgery

Thanks to medical technology advancements, cataract surgery has become a safe and straightforward procedure. In 1949, Sir Harold Ridley pioneered the use of intraocular lenses (IOL) to replace the natural lens removed during cataract surgery. After his surgery, the patient's vision improved significantly, and the IOL remained implanted for life.In the early days of modern cataract surgery, the procedure involved making a large incision and manually removing the clouded lens. Nowadays, cataract surgery is mostly performed using a technique called phacoemulsification. A tiny incision is made in the cornea, and a probe with a vibrating tip is inserted to emulsify and remove the cataract in fragments. Then, an IOL is implanted to restore the eye's vision.

Post-Operative Care and Recovery

After cataract surgery, patients need to follow specific guidelines for post-operative care and recovery. Here are some of the things they should keep in mind:

After Surgery Care

After surgery, the patient's eye may feel sore and itchy for a few days. They should avoid touching or rubbing the eye, as well as activities that could strain it, like lifting heavy objects. Eye drops may be prescribed to reduce inflammation and prevent infection. Antibiotics and anti-inflammatory medications may also be prescribed.

Return to Normal Activities

The patient should avoid any activities that could potentially harm the eye for at least a week after surgery. This includes swimming, bending over, and engaging in strenuous exercise. They should also avoid dusty or dirty environments that could cause irritation. After a week, most patients can resume their normal activities.

Follow-Up Appointments

Follow-up appointments are essential to ensure proper healing and check for any complications. Patients should attend all post-operative appointments scheduled by their ophthalmologist. During these visits, the surgeon will examine the eye, monitor the healing process of the incision, and adjust medications if needed.


Cataract surgery has come a long way since ancient times. Over the centuries, different techniques and instruments were developed, some of which were more successful than others. Nowadays, cataract surgery is a safe and effective procedure that has helped millions of people around the world to recover their vision. With proper post-operative care and follow-up appointments, patients can expect a successful outcome after surgery.
