RESUMEN
The history of the cataract operations dates back to thousands of years ago. Initially, surgery was carried out using rudimentary operating techniques resulting in the loss of many eyes. Cataract surgery has evolved immersely and now it is a highly refined surgical practice. Evolution of the cataract surgery was closely linked to broadening of anatomical-pathological knowledge and to the development of the instruments applied. Although Daviel performed the first intentional cataract removal in 1747, almost one hundred years passed before the extracapsular cataract extraction method finally replaced the old couching technique. By the middle of the 20th century, with the progression of the operation techniques and instruments, different forms of intracapsular cataract extraction methods became prevalent. Introduction and widespread use of the artificial intraocular lenses from the second half of the 20th century led to the rediscovery and further perfection of the extracapsular cataract extraction technique. Today, phacoemulsification through small incision, along with the foldable intraocular lenses is the gold standard of cataract surgery. The aim of this study is to present the different cataract surgery methods applied throughout the centuries, as well as the difficulties encountered. It discusses pioneering steps of each era, in order to give a closer look at the most frequently performed surgical intervention in ophthalmology.

Charles David Kelman was born in Brooklyn, New York, USA, on 23 May 1930 and passed away in Boca Raton, Florida, USA, on 1 June 2004 at the age of 74 years after a long battle with cancer. He received a Bachelor of Science degree from Tufts University in 1950 and completed medical studies at the University of Geneva, Switzerland, in 1956. He was Clinical Professor of Ophthalmology at New York Medical College and an Attending Surgeon at New York Eye and Ear Infirmary and Manhattan Eye, Ear and Throat Hospital. Although a prolific inventor, he will be best remembered for developing phacoemulsification, following his realization while sitting in a dentist's chair, that ultrasonic vibrations could be used to emulsify the aged crystalline lens through a very small incision. His pioneering work revolutionized cataract surgery. He also pioneered cryo-extraction of cataracts, the use of freezing for the repair of retinal detachments and designed numerous ophthalmic instruments and intraocular lenses. Dr Kelman received numerous awards, including the American Academy of Ophthalmology Achievement Award (1970), the Ridley Medal from the International Congress of Ophthalmology (1990), and the Inventor of the Year Award from The New York Patent, Trademark and Copyright Law Association (1992). Most recently (2003), Dr Kelman was honoured by the American Academy of Ophthalmology with the Laureate Recognition award. Dr Kelman was also an accomplished Broadway producer, composer and jazz saxophonist. With his demise, the ophthalmic and medical community lost a famed inventor with multifaceted talents and one of the great ophthalmologists of the twentieth century.

Even though cataract surgery has been practiced for over 2000 years, modern cataract surgery started just some 50 years ago. with the first IOL implantation by Sir Harold Ridley. The development of intraocular lenses was accompanied by great successes and disasters. With the fast development of cataract surgical techniques over the past 15 years (ECCE, Phacoemulsification, Capsulorhexis) a successful marriage between IOL-developments and surgery was established. Indication profiles for cataract surgery and IOL implantation extended to more and more patient groups. At this time classical cataract surgery is further developing into refractive intraocular lens surgery to correct higher ametropia in clear lens or phakic eyes. This development was only possible because of the improvements of surgical techniques and implants in classical cataract surgery.

The techniques and results of cataract surgery have changed dramatically during the past three decades. In the USA, we have moved from intracapsular cataract extraction as the preferred technique to almost exclusively extracapsular techniques. Smaller incisions have become the standard, with phacoemulsification now being the method of choice for most surgeons. Along with these advances have come improved intraocular lens materials and designs, especially well suited for use with smaller incisions. Phacoemulsification as a method to remove the cataractous lens was first proposed more than 20 years ago. Advances in techniques and equipment have led to a dramatic increase in the popularity of phacoemulsification with increased safety and efficiency. Viscoelastic agents have been developed synchronously with modern phacoemulsification techniques, playing an integral role in the success of this new technology. Improved surgical techniques for removing the anterior lens capsule have decreased the incidence of both intraoperative and postoperative capsular complications. Nucleus removal, formerly performed primarily in the anterior chamber, is now performed in the posterior chamber, decreasing damage to the corneal endothelium. Improved wound construction allows many wounds to be left unsutured, and smaller wounds allow shorter recovery time and greater intraoperative control and safety. Intraocular lenses can have smaller optic sizes and still maintain accurate centration. Foldable intraocular lenses can take advantage of the smaller incision, even further shortening the time to visual recovery. Continual evolution of this technology promises to further improve patient outcomes after cataract surgery.

Phacoemulsification procedures with topical anesthesia, performed with small corneal incisions and 4% lidocaine hydrochloride methylparaben-free eye drops, have very high patient satisfaction rates because patients do not experience intraoperative pain, do not require sutures or eye patches, and have immediate improvements in their vision. Phacoemulsification procedures with topical anesthesia are cost-effective for surgery departments because patients have shorter hospitalizations and require fewer chargeable items. The perioperative nursing role is essential to the success of phacoemulsification procedures with topical anesthesia.
