Jacques Daviel: The Man Who Revolutionized Cataract Surgery

On July 28, 1851, a remarkable event took place that revolutionized the field of ophthalmology and paved the way for modern cataract surgery. On this day, French ophthalmologist Jacques Daviel successfully performed the first extracapsular cataract extraction, a groundbreaking surgical technique that involved removing the cloudy lens of the eye while leaving the capsule intact.

Prior to Daviel's innovation, the standard treatment for cataracts was a procedure called couching, which involved using a sharp instrument to push the cloudy lens back into the vitreous humor, allowing light to enter the eye. However, this method often led to complications such as infection, inflammation, and even blindness.

Daviel's extracapsular cataract extraction technique was a significant advancement. He made an incision in the cornea, carefully opened the anterior capsule of the lens, and extracted the cataractous lens material. This approach allowed for better visual outcomes and reduced the risk of complications.

Daviel's first successful surgery took place in Paris, France, on a 50-year-old man who had been blind for several years due to cataracts. The operation lasted about 15 minutes, and the patient's sight was successfully restored. News of Daviel's achievement spread quickly throughout Europe, and his technique soon became the standard method for cataract surgery.

Daviel's contributions to ophthalmology extended beyond his surgical innovation. He also designed several instruments that improved the precision and safety of eye surgery, including a special knife for making corneal incisions and a curved needle for suturing the eye.

The impact of Daviel's work cannot be overstated. Before his breakthrough, cataracts were a leading cause of blindness worldwide, and treatment options were limited and often dangerous. Daviel's extracapsular cataract extraction technique laid the foundation for modern cataract surgery, which has restored sight to millions of people around the globe.

Today, cataract surgery is one of the most common and successful surgical procedures performed, with over 10 million surgeries conducted annually worldwide. Advances in technology, such as the use of ultrasound (phacoemulsification) to break up and remove the cataractous lens and the development of intraocular lenses (IOLs) to replace the removed lens, have further improved outcomes and recovery times.

In honor of Jacques Daviel's pioneering work, July 28 is celebrated as Cataract Surgery Day in some parts of the world. His legacy serves as a reminder of the transformative power of scientific innovation and the importance of continually striving to improve patient care and outcomes.

As we commemorate this significant event in science history, it is worth reflecting on the countless individuals whose lives have been changed by Daviel's groundbreaking work and the many ophthalmologists who have followed in his footsteps, dedicating their careers to preserving and restoring sight.

Welcome to This Moment in Science History podcast. On July
twenty eighth, eighteen fifty one, a remarkable event took place
that revolutionized the field of optomology and paved the way
for modern cataract surgery. On this day, French optomologist Jacques
de Villelle successfully performed the first extracapsular cataract extraction, a

groundbreaking surgical technique that involved removing the cloudy lens of
the eye while leaving the capsule intact. Prior to Deville's innovation,
