Cataract surgery has been known to humanity for ages. The first documented cataract surgical procedure dates back to the fifth century BC. Today, the advanced and sophisticated technologies used in cataract surgery have made it incredibly useful and virtually painless. History and Types of Cataract Surgery The surgery for cataracts is one of the oldest. The ancient Indian doctors used a technique called ‘couching’ to perform cataract surgery. In this technique, the surgeon would dislodge the cataractous lens into the back of the eye, thus removing it from the visual axis and enabling light to enter the eye. Ancient Greeks and Egyptians used a similar method called “needling”. In this method, the cataract was sliced into multiple particles. The small particles were then allowed to be easily absorbed by the body. Although these techniques did not remove the cataract from the eye, they purposefully dislodged the mature cataract out of the visual axis. Thus, couching and needling techniques helped in restoring limited but unfocused vision. Later, cataract extraction surgery replaced the couching technique. The ancient literature suggests that an Indian surgeon, named Sushruta, is the first surgeon to perform extracapsular cataract extraction as early as 600 BC. The first recorded surgical cataract extraction from the West was performed successfully in Paris in 1747 by the French surgeon Jacques Daviel. Evolution of Cataract Surgery Fortunately, cataract removal surgery in recent times has come a long way. Modern cataract surgery, which involves Intraocular Lens Implants (IOL), did not occur until the mid-20th century. Dr Harold Ridley researched replacing cataractous eye lenses with an artificial lens made of polymethyl methacrylate. With some failed attempts, he could establish the use of implants for replacing the natural lens of the eyes. Here are some cataract surgery techniques which are widely used today: Extracapsular cataract extraction: This is not a widely practised technique and involves a 6mm limbal incision (incision at the junction of the cornea and sclera) with the delivery of the cataractous lens in toto, implantation of an intraocular lens and closing the incision with 5 or 6 sutures. The disadvantages of this technique are slow healing, suture-induced astigmatism, and average refractive outcomes. Small Incision Sutureless Cataract Surgery: This technique involves a scleral tunnel incision. However, it is a stitchless surgery. Small incision sutureless cataract surgery is the best choice of procedure in certain advanced cases of cataracts where phacoemulsification is not possible or the patient is at risk of corneal damage. cataract surgery Small incision sutureless cataract surgery Phacoemulsification: Charles Kelman developed a groundbreaking phacoemulsification technique in 1967. In this, ultrasonic vibrations are used to break the cataract into smaller particles, which are then removed by aspiration. Today, this is the most commonly performed technique for cataract extraction. Micro-Incision Cataract Surgery: It’s a modern approach to cataract surgery. In this surgery, a small incision of less than 1.8 mm to 2.0 mm is made to reduce surgical invasiveness and to improve refractive outcomes. Phacoemulsification Phacoemulsification procedure Laser-assisted Cataract Surgery: Laser-assisted surgery is the latest advancement. In this method, the ophthalmologist uses a laser to create the corneal incision. This bladeless incision offers unparalleled accuracy and precision. With the help of Optical Coherence Tomography, the eye surgeon plans out a 3D image of the eye and carries out the surgery.
