Who Invented Laser Eye Surgery

Advancing Into The 19th Century

Who invented laser eye surgery?

As advances in glasses manufacturing continued, contact lenses, while actually theorised by Leonardo Da Vinci in 1508, didnt arrive in practice until 1888 when Adolf Gaston Eugene Pick designed the first lenses to be placed on the surface of the eye to correct vision. These heavy glass lenses could only be worn for a few hours at a time. In the 1960s, softer plastic and also gas permeable lenses were developed that allowed the more modern lenses we know now which can be worn on the surface of the eye for an entire day.

Role Models Who Fueled Her Passions

Dr. Bath revealed that mentors played a crucial role throughout her life. She pointed to multiple individuals who encouraged her at various stages from planting the first seeds of inspiration to helping her make specialized career decisions.

Born on November 4, 1942, in Harlem, NY, Patricia Bath grew up in a predominantly Black community. As a result of a racist housing policy known as redlining, her community included people from many economic classes.

One of her neighbors, Dr. Cecil Marquez, was her family physician, and his influence first gave her the motivation to go into medicine.

On the recommendation of her high school teacher, Dr. Bath applied and was accepted to conduct research through the National Science Foundation. This opportunity served as the groundwork for her continued explorations in scientific research.

She continued on this path to medicine, and, in 1968, she received her medical degree at Howard University College of Medicine in Washington, D.C.

In a conversation with Dr. Eve Higginbotham, a Black colleague who specializes in glaucoma, Dr. Bath highlighted two women who offered her concrete direction in pursuing a career in ophthalmology.

The first was Dr. Lois A. Young, who served as the Acting Chief of Ophthalmology during Dr. Baths time at Howard.

She was also the first Black woman to join the faculty of the University of Maryland as an ophthalmologist, where she was well-loved by her patients, and people knew her for her trailblazing work.

What Makes Lasik Such A Popular Choice

LASIK is currently the most commonly performed type of refractive surgery. Its also the most popular form of elective surgery in the world! There are number of factors that make it the go-to choice for patients:

  • Its generally less painful and more comfortable than alternatives like LASEK
  • Recovery is quick
  • The risks associated with the procedure are small.

Its important to note, though, that everyone is different. Some patients may be more suited to LASEK or other refractive surgical procedures. For example, if you have thin corneas, LASIK may not produce the best results for you.

If you opt for LASIK with OCL, youll benefit from the most advanced laser technology currently available. Combined with the skill and experience of surgeons at the forefront of their field, youre in safe hands!

Refining Lasik And Creating New Procedures

In the present day, LASIK eye surgery is still on a path of innovation, as scientists and eye doctors continue to develop new technology. Patients can now choose unique options like , which relies on a laser to create the flap, rather than a blade. The excimer laser remains a key part of laser eye surgery, and continues to be optimized over time.

Advances in the technology used to map the eye before surgery have also been a big part of the LASIK story, with procedures like Custom LASIK and Topography-Guided LASIK providing more precise data than ever to help plan your procedure. The detailed data helps surgeons customize your procedure to deliver the best results for your unique vision care needs. LASIK patients truly now have more options than ever before.

If the history of laser eye surgery tells us anything, its to expect LASIK technology to continue evolving. Procedures like Bladeless all-laser LASIK , Topography-Guided LASIK, and Custom LASIK each offer unique benefits, but none of it would have been possible without the many people who contributed to the development of laser eye surgery.

Racial Injustice And Discrimination

Dr. Baths accomplishments and titles are admirable. However, her numerous firsts as a Black woman also underscore the structural and institutional racism that prevent other women of color from joining her in these achievements.

These structures were prevalent from Dr. Baths roots in Harlem, an area that endured a long history of racist policies that limited access to resources, such as financial programs and education.

Even once she reached the reputable positions of leadership, Dr. Bath continued to face sexism and racial discrimination.

In 1975, Dr. Bath joined the Jules Stein Eye Institute at the University of California, LA, as the first woman on the faculty in the Department of Ophthalmology.

Despite usually assigning office spaces according to academic rank, the Institute offered her an office in the basement next to the lab animals, which she refused.

Medical schools and societies, such as the American Medical Association, have a history of refusing to admit Black students. Even once these institutions opened their doors to them, these students faced constant discrimination and a lack of support.

Why Laser Eye Surgery

Laser eye surgery today, is the best option to lead a free and comfortable life without glasses. Many have chosen to take the laser way of life, and have been leading quite a happy life with fully corrected vision.However, even though rare, there are risks of over or under corrections in laser. And this is where you would need to choose the right surgeon for yourself, someone who has a time tested record in the field of laser eye surgery, and will be capable of gifting you your eyes without the glasses.

Brief History Of Laser Eye Surgery

Laser eye surgery has come a long way since its very beginnings in the 1940s. From new research and technology, laser eye surgery has become very effective, safe and routine now for millions of individuals around the world that undergo the procedure each year. If you are looking to rid yourself of the hassle of glasses or contacts, you are able to today very easily thanks to the doctors and surgeons who paved the way to allow a safe surgical method to correct a variety of vision problems. Even now, there are new device advancements, techniques and methods coming out all the time to improve upon what already is available. Here is a brief history of refractive laser surgery and how it developed into what it is today.

1948- Father Waclaw Szuniewicz, Polish missionary, and ophthalmologist

  • Considered to be the pioneer of refractive surgery, Father Szuniewicz came to the United States in 1948 to continue pursuing his experimentation of corneal reshaping at Yale University in New Haven, CT.

1964- Professor Jose Ignacio Barraquer

1970- Svyatoslov N. Fyodorov, MD

  • Dr. Fyodorov invented radial keratotomy, which decreases nearsightedness by a series of incisions into the patients cornea at specified depths. The location and number of incisions was dependent upon the amount of nearsightedness.

1973-1983- Excimer Laser

1991- Stephen Slade, MD and Dr. Stephen Brint, MD

What Is The Future Of Lasik

Dr. Patricia Bath: Inventor For Laser Eye Surgery

At the University of Maryland, researchers are looking to remove the surgery element of LASIK. They are looking at a microscopy technique that would eliminate surgeons from making approximations. Instead, they will use measurements that are precise regarding how the eye focuses light.

This technology would allow doctors to map the variations and distribution of the eyes local refractive index. As a result, they would have the precise degree of corneal refraction. With this advancement, surgeons could more definitively provide patients with 20/20 or greater vision. It could also potentially eliminate the need to cut into the cornea to perform LASIK.

Some scientists are trying to find ways to eliminate the need to use lasers for LASIK. Instead, they are brainstorming ways to use eyedrops to correct refractive errors. While this advancement could be possible, it is still believed to be decades away.

Understanding Laser Eye Surgery

Laser eye surgery has helped millions of people be able to eliminate the need for cumbersome glasses or contacts. There are several types of laser vision corrections, such as LASIK,PRK, and SMILE®, which reshape the cornea to allow better focus. Laser eye surgery commonly corrects long and short-sightedness, astigmatism, cataracts, and presbyopia. The surgery is essentially painless and requires no stitches or bandages. Patients will see a nearly immediate improvement in vision.

Today: Continuing To Evolve

While technology has improved drastically over the last two decades, the basic concept of LASIK is still the same. The efficacy of LASIK has improved dramatically. The understanding of who makes for a good candidate has expanded. The accuracy of visual outcomes has increased. And the future of this simple, yet life-changing, the procedure is even brighter now than it was for the ground-breaking innovators of the past 65 years.

S The Origins Of Refractive Surgery

Refractive surgery had its beginning in 1948 when Father Waclaw Szuniewicz, a Polish missionary and ophthalmologist experimented with changing the shape of the cornea and the impact it had upon eyesight. From 1931 to 1949 he served as a missionary and as the head of the Department of Ophthalmology at a hospital in Shuntehfu, China and then in 1949 continued his research at Yale University.

S Prk And Development Of The Flap

Dr Patricia Bath: "  She

The first laser vision correction procedure took place in 1988 at the Louisiana State University Eye Center in New Orleans, when a 60-year old woman allowed surgeon Marguerite McDonald to perform the first photorefractive keratectomy procedure on her damaged eye. PRK surgery was approved by Canada in 1991, approved by the US in 1995, and remains in use to this day.

While the results of the first PRK surgery helped allow the procedure to reach the wider market, European eye doctors Ioannis Pallikaris and Lucio Burrato were busy working on ways to optimize laser eye surgery. They made the discovery that creating a flap in the cornea, rather than removing the epithelium layer, helped to reduce post-surgical discomfort and accelerate the healing process. The flap allowed surgeons to gain access to the cornea, perform the shaping and replace when complete thereby aiding the healing process. This innovation signaled the dawn of modern day LASIK eye surgery and was approved by the FDA for use in the United States in 1999.

A Brief History Of Lasik Eye Surgery

Laser-assisted in situ keratomileusisâbetter known as LASIKâuses lasers to subtly reshape the cornea. This changes the way the eye refracts light, and can help a person see better.

More than 10 million people have had LASIK since its approval by the U.S. Food and Drug Administration in 1999. So how did this relatively new procedure begin shaping not just eyes, but lives and appearances?

The history of LASIK dates all the way back to 1948.

Who Invented Lasik And When A Brief History Of Laser Eye Surgery

To the average observer, it seems as if LASIK exploded onto the scene as an accepted and routine procedure. In many respects, it did. But if we look back at its development, we will see that it is more like an explosion that happened in slow motion.

Timeline Of Events Leading To Laser Eye Surgery

1896 An ophthalmology teacher, Dr Lendeer Jans Lans, published a paper discussing methods of rectifying corneal curvature, and curing astigmatism . He theorised that making cuts in the cornea could smooth out the surface of the eye and improve a patients vision. This research provided crucial insights for the first surgeries on the cornea, decades later.

1930 Tsutomu Tsato, a Japanese ophthalmologist practised eye surgery on war pilots. He made incisions, or small cuts, into the cornea to dramatically improve the pilots vision sometimes by up to 6 Dioptres! While his technique initially worked in the period following the surgery, it caused the patients corneas to deteriorate quickly, overall damaging their vision.

1948 Next came a Polish ophthalmologist, Father Waclaw Szuniewicz, who was a pioneer in changing corneal curvature through surgery. He travelled to the US and experimented with refractive surgery at Yale University.

1963 Professor Jos-Ignacio Barraquerr, a Columbian ophthalmologist, was the first to develop a technique called keratomileusis, which involved reshaping the cornea. To do this, Barraquerr removed a layer of the cornea, froze it to reshape it, and then re-implanted it. Although this method brought some success, it wasnt considered very precise for achieving exact prescriptions.

Different Types Of Laser Eye Surgery

Dr. Patricia Bath invented and received patents for laser eye surgery. She holds 4 patents.

Not all laser eye surgery is the same. Depending on your current eyesight, age, lifestyle, shape of the cornea, and a number of other factors, your doctor can recommend any one of the different kinds of refractive operations.

Other similar procedures include EpiLASIK presbyopic lens exchange , where a natural lens that is too rigid is replaced with a multifocal, flexible lens to help patients focus better and Intacs, also known as intracorneal ring segments or ICR, where two crescent-shaped plastic rings are placed at the outermost edge of the cornea to flatten it, which allows for light rays to be refocused onto the retina. ICR has been mostly replaced by laser-based operations in the treatment of myopia.

The First Human Laser Eye Surgery

On March 25th, 1988 the very first live human laser eye surgery took place in Louisiana. The surgeon, Marguerite B. McDonald, along with her research team including Stephen Trokel, performed a PRK procedure on a 62-year-old woman with cancer. The success of this first operation spurred the FDA to start allowing trials to be performed on blind humans.

In 1995, a commercial version of laser eye surgery was approved by the FDA.

The First Laser Vision Correction Procedure

Getting Ready For Laser Eye Surgery

How do you know if laser eye surgery is for you? There are a few ways to determine if you meet the qualifications to get refractive surgery. To start, talk with your eye doctor or primary care physician to find out if you would benefit from the procedure and if you have any medical conditions that might impact the effectiveness of the procedure and the progression of recovery. This might entail answering questions about your familys medical history, your lifestyle, and your general health.

If you use contact lenses, you should switch to glasses for a bit. Contact lenses can change the shape of the cornea, and the eyes need to return to their normal shape in order for the laser eye surgery to be effective. Your eye surgeon will need to take exact measurements of your eyes to prepare for your surgery, and wearing glasses will ensure that the measures are as precise as possible. These measurements include examining corneal thickness, vision and prescription testing, eye pressure, and pupil dilation, among others. These tests are quite easy to conduct, but wearing contact lenses will deprive your doctor of the accurate information they need.

Patients who wear soft contact lenses should not wear them for a week before the surgery. Patients with hard contact lenses should use glasses for up to a month before the surgery.

Laser Eye Surgery Research In The 1970s

The History Lasers timeline

The story of LASIK begins long before the first procedure was performed, in the research halls of major universities and businesses. Throughout the late 1970s, a procedure called Radial Keratotomy , which shares similarities with LASIK, was performed in the United States. A major breakthrough came in 1980, when IBM researcher Rangaswamy Srinivasan discovered that the excimer laser initially developed for computer chip production was able to remove living tissue without causing thermal damage. Surgeon Steven Trokel of Columbia University published a key study in 1985 detailing the effectiveness of the excimer laser for RK surgery, which helped pave the way for LASIK eye surgery.
