Harold Ridley attempted to replace inner eye lenses in cataract patients. Though these efforts were unsuccessful for the most part, Ridley introduced the idea of lens replacement, a method that changed the course of history. A process known as phacoemulsification was developed by Dr. Charles Kelman in This technique used ultrasonic vibrations to break cataracts into smaller segments. Once this step was complete, the particles were removed with a small probe. While this procedure was helpful for removing cataracts, doctors still needed a way to effectively replace the lens.
Kai-yi Zhou placed the first foldable eye implant in Crafted from silicone, this device could be rolled or folded up, which made insertion through smaller openings possible. One of the most important discoveries in the field of ophthalmology was made by Dr. Patricia Bath in She invented the laserphaco probe, which used light energy to ablate and remove cataracts. This treatment was revolutionary and helped Dr.
Bath restore vision in patients who had been blind for more than three decades. Today, over 25 million Americans suffer from cataracts.
Fortunately, due to the research and developments of those who came before us, we now have lenses that offer a 98 percent success rate. If your vision is clouded due to cataracts, our team can help improve your quality of life. Fortunately, because of advances in technology, cataracts can now be removed and replaced with an intraocular lens IOL with a low complication rate.
However, the lack of aseptic technique and rough nature of the procedure resulted in poor outcomes [4]. Some common complications include secondary glaucoma, hyphema, endophthalmitis, and often results in blindness. Unfortunately, couching is a traditional procedure that is still used today in parts of the world like Northern Nigeria and West Africa due to a multifactorial combination of unfamiliarity of modern procedures, fear of surgery, and preference of relying on traditional methods [4] [5].
While many used the couching technique, there are texts as early as BC that document the use of a primitive extracapsular cataract extraction ECCE - meaning the lens is removed and the lens capsule is left in place - by an Indian surgeon named Sushruta.
A translation of the original text in Sanskrit discloses the following operative technique: a sharp needle punctured the eye through the aqueous humor until reaching the capsule of the lens where the surgeon would make an incision. Postoperatively, indigenous roots and leaves were applied in a bandage and the patient was instructed to lie flat and avoid strenuous activities including cough and sneezing [6].
For centuries despite some documentation of primitive ECCE, couching was the main procedure for cataracts until when French surgeon Jacques Daviel, often credited as the father of modern cataract extraction surgery, performed an ECCE.
Post operative care included dressing the eye with a cotton dressing soaked in wine and lying in a darkened room for a few days. Although this was a great advancement from couching, significant complications were prevalent such as posterior capsular opacification, retained cataracts, and infection [4] [7].
While Daviel was credited as the first to perform ECCE, in a London surgeon by the name Samuel Sharp is the earliest documented to perform intracapsular cataract extraction ICCE , this involves the removal of the opacified lens and the surrounding capsule in one piece. There are different variations to this method but essentially all of them require lysing the zonular fibers that support the lens capsule and followed by subsequent removal of the lens-bag complex through a large limbal incision.
Unfortunately, because the lens capsule acts as a barrier between the anterior and posterior chamber, its removal often causes vitreous prolapse and subsequent retinal detachments among other complications. Furthermore, removing the lens and capsule in one piece requires a large incision, resulting in longer healing times and higher infection rate [4].
An important function of the natural lens is to refract light waves so that they are focused on the retina, providing a clear image. Patients without such lenses are considered aphakic and before the advent of intraocular lenses IOLs required often high-powered, bulky spectacles, which often led to poor visual quality. Ridley observed that one of the Royal Airforce pilots had sustained shrapnel ocular trauma from plastic and despite having a foreign body, remained largely asymptomatic for years.
In Dr. Ridley was credited to perform the first IOL operation at St. His work was met with disdain as this was a revolutionary idea of inserting a foreign object inside the eye. Further criticism stemmed from complications such as glaucoma, inflammation, inability to individualize the refractive strength of the IOL, and frequent dislocation of the IOL.
Ridley admits that further work was necessary to address many of the complications, but his innovative work paved the way for modern advancements in IOL and cataract surgery [4] [8].
Some of the benefits of the foldable IOL are easier implantation and a small incision, resulting in less induced astigmatism, faster healing and fewer infections [9]. The conglomeration of foldable IOL, use of topical anesthetics in by Fischman, and the introduction of phacoemulsification in by Dr.
Charles Kelman allowed for the modern extraction of cataracts to be effective and safer [10]. Phacoemulsification uses ultrasound to break up the cataract and then subsequently the cataract is aspirated from the eye.
This development allowed surgeons to decrease the incision in the eye from 10mm to typically less than 3mm, which has the benefits of shorter recovery times, more stable surgery, and lower complication rate.
