From Ancient Efforts to Modern Miracles: The Ever-Evolving Story of Cataract Surgery

Yesterday, my wife Susie had cataract surgery. When the process was explained it stimulated many questions. How did doctors learn how to do this, to remove the lens in an eyeball and replace it with a better lens? When did people first begin to have cataracts and how did they deal with it? 

For what it's worth, a cataract is a cloudy area in the lens of the eye. The formation of cataracts is a natural phenomenon in the aging process. It's different from glaucoma, an eye disease which damages the optic nerve.

The history of cataract surgery spans thousands of years. As you can imagine, humankind's earliest attempts to solve this eye problem were quite crude, especially compared to our modern advancements. I asked ChatGPT to outline the history of cataract surgery. I'm sure the earliest efforts would make you wince. 

Here's an outline of this eye surgery's key milestones:

  • Ancient Times: Cataract surgery has ancient origins, with evidence of attempts to treat cataracts found in Egyptian and Indian texts dating back to 29–30 BCE. Ancient surgeons often attempted to dislodge cataracts from the eye using sharp instruments.
  • Medieval Arab Surgeons: During the medieval period, Arab physicians made significant contributions to ophthalmic surgery. They developed techniques such as couching, where a needle or sharp instrument was used to displace the clouded lens to the bottom of the eye, allowing some vision to be restored. However, this method did not restore clear vision and carried a high risk of complications.
  • 16th to 18th Centuries: European surgeons continued to refine techniques for cataract surgery, but outcomes remained poor, often resulting in blindness or severe complications.
  • 18th Century: The introduction of the extracapsular cataract extraction technique by French surgeon Jacques Daviel in the 18th century marked a significant advancement. This technique involved making an incision in the eye and removing the lens while leaving the lens capsule intact.
  • 19th Century: The development of anesthesia and a better understanding of antiseptic techniques in the 19th century led to safer cataract surgeries. Surgeons began to experiment with intraocular lens implantation, but initial attempts were largely unsuccessful due to issues with biocompatibility and rejection.
  • 20th Century: The 20th century saw significant advancements in cataract surgery techniques and technology. In the 1940s, Sir Harold Ridley pioneered the use of intraocular lenses (IOLs), which are now a standard part of modern cataract surgery. The introduction of phacoemulsification in the 1960s revolutionized cataract surgery by allowing the lens to be broken up and aspirated through a tiny incision, leading to quicker recovery times and fewer complications.
  • 21st Century: Cataract surgery continued to evolve in the 21st century with the introduction of femtosecond laser-assisted cataract surgery, which offers greater precision and customization. Additionally, advancements in IOL technology have led to improved outcomes, including multifocal and toric lenses that can correct presbyopia and astigmatism.

Today, cataract surgery is one of the most commonly performed surgical procedures worldwide, with a high success rate and minimal risk of complications. As you can see, dealing with cataracts has certainly come a long way. Today it has become a cornerstone of modern ophthalmic practice.
