We can often take eye care innovations for granted. Many common surgeries today took hundreds of years to get to the point they are today. For instance, advanced surgery for the removal of cataracts to restore patient vision can trace its roots back almost 2,000 years.
The team at Choate Eye Associates would like to go over some of the key moments in the history of cataract surgery. If you want more information about modern cataract removal techniques and live in the Nashville, TN area, Dr. Walter Choate would be happy to discuss them with you during a consultation.
The earliest cataract surgery can be traced back to Greece in the 2nd century AD. The physician Galen of Pergamon removed a cataract from a patient’s eye using a needle-shaped instrument. Galen of Pergamon developed his understanding of the eye thanks to animal research and his work on humans.
Around the 2nd century AD, another Greek physician named Antyllus developed an instrument made from bronze that could remove a cataract through the use of oral suction.
In India during the 3rd century AD, eye doctors would perform couching in order to remove cataracts. This dangerous technique used a sharp object to dislodge the cataract. The Indian physician Sushruta spread this technique to other countries in the region. Unfortunately, an estimated 70 percent of couching procedures resulted in blindness.
Cataract surgery techniques spread to to China and experienced significant improvements in the Sui Dynasty (581-618) and Tang Dynasty (618–907).
In addition to preserving and translating many Ancient Greek and Roman texts, the Islamic world also contributed to cataract surgery and eye care.
Improving on techniques that came before, 10th century Persian physician Muhammad ibn Zakariya al-Razi developed a cataract removal technique that involved the use of Antyllus’ suction equipment. The 10th century Iraqi ophthalmologist Ammar Al-Mawsili also performed a similar cataract surgery that involved suction. The 14th century Egypt oculist Al-Shadhili noted different take on this oral suction instrument; this new device used a screw to produce suction rather than the mouth.
There were a number of important medical innovations from the 1600s to the 1800s. Some highlights released to cataract removal include:
Modern cataract surgery began around the 1940s thanks to innovations in materials and medical knowledge. During the 1940s, English ophthalmologist Sir Nicholas Harold Lloyd Ridley created the intraocular lens (IOL). This implantable lens replaced the clouded lens once it was removed, leading to improved vision for patients following surgery.
In 1967, a new method of cataract removal was developed that improved comfort, safety, and effectiveness. American ophthalmologist Charles D. Kelman created a technique known as phacoemulsification. This broke up the lens of the eye into smaller pieces so it could be removed easier without a large incision.
The last important development we'll cover is in 1978. In that year, Chinese eye surgeon Kai-yi Zhou successfully placed the first foldable IOL. This foldable lens allowed eye surgeons to place an IOL using a small incision. This again improved patient comfort and overall effectiveness of surgery.
