Key takeaways

  • Tibor Juhasz belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Tibor Juhasz to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Tibor Juhasz from memory before moving on to harder problems.

Reference excerpt

Tibor Juhasz is an American-Hungarian physicist and entrepreneur. He is a professor of ophthalmology and biomedical engineering at the University of California, Irvine School of Medicine, as well as the President and CTO of the medical device company ViaLase. Juhasz is best known for his work on medical applications of lasers. He and ophthalmology professor Ron Kurtz are the inventors of IntraLASIK, a device which uses femtosecond lasers to prepare the eye for LASIK surgery. IntraLASIK has since become standard procedure when performing LASIK surgery. Juhasz has also developed similar devices to treat cataracts and glaucoma. Juhasz has also founded several companies to commercialize his inventions. Two of his companies, IntraLase and LenSx, were later acquired by major medical device companies for hundreds of millions of dollars. His third, ViaLase, is currently active; its product, a device which uses femtosecond lasers to treat glaucoma, is currently in the final stages of clinical trials. Juhasz is the recipient of the 2002 Berthold Leibinger Innovation Prize for the development and commercialization of femtosecond laser surgical technology. He also received the 2022 Golden Goose Award from the American Association for the Advancement of Science and Association of American Universities for introducing femtosecond laser technology to ophthalmology.

Education Juhasz completed his Diploma in Physics from the University of Szeged in 1982. Four years later, he received a Ph.D. in Physics from the same institution. He completed his postdoctoral education at the Department of Physics and Astronomy at the University of California, Irvine from 1987 to 1990. Later, in 2001, he obtained a Doctor of Sciences degree from the Hungarian Academy of Sciences.

Career

Early career Juhasz began his academic career in 1982 as a research assistant in the Department of External Physics at the Technical University of Budapest (BME). In 1985, was made an assistant professor. He stayed at BME for two more years, before leaving in 1987 to complete a postdoc with the Department of Physics at the University of California, Irvine. It was during this time that Juhasz began to investigate the interactions between ultrashort laser pulses and matter. Three years later, in 1990, he was promoted to the role of Assistant Researcher Physicist.

Femtosecond lasers in corneal surgery Juhasz left UC Irvine in 1994. Two years later, in 1996, he met ophthamologist Ron Kurtz at a conference in Toronto. At the time, Kurtz was collaborating with a team of researchers at the University of Michigan (UMich) on a project investigating the potential applications of femotsecond lasers in ophthalmology. Juhasz, who was investigating the use of picosecond lasers for eye surgery, struck up a conversation with Kurtz, and soon Juhasz was invited to join the UMich team. Juhasz remained at UMich for eight more years, rising to the rank of associate professor in 1998. During his time at the university, he and Kurtz developed a device that used femotsecond lasers to create a flap in the cornea, a necessary first step for many kinds of eye surgery, including LASIK. At the time, corneal flaps had to be created surgically with a microkeratome knife, a process that was both painful for the patient and had an extended recovery period. Their invention, which they named IntraLASIK, allowed the procedure to be performed bladelessly, greatly reducing both the pain involved and the recovery period afterwards. Juhasz would go on to win the Berthold Leibinger Innovation Prize for his work in 2002. In 1997, the two men founded the company IntraLase to commercialize IntraLASIK. Upon receiving FDA approval, the device became the first commercially available ophthalmic femtosecond laser. Juhasz initially served as the company's vice president for R&D until 2002, when he became its chief technology officer (CTO). During this time, Juhasz returned to UC Irvine, accepting the role of professor at the Gavin Herbert Eye Institute in the Department of Biomedical Engineering in 2004. His research there showed that IntraLASIK offered enhanced safety and yields superior refractive outcomes in comparison to the conventional microkeratome method. Furthermore, his work established that employing femtosecond laser technology for corneal transplantation offers distinct benefits in comparison to conventional methods.

Femtosecond laser cataract surgery In 2007, IntraLase was acquired by Advanced Medical Optics for $808 million. After its sale, Juhasz and Kurtz began investigating other potential ophthalmic applications of femtosecond lasers. The two collaborated with Hungarian researcher Zoltan Nagy to design and develop the first clinical cataract femtosecond laser. Later research by Juhasz would demonstrate that the mechanical strength of femtosecond laser capsulotomy is on par with that of manual capsulotomy, but with a significantly reduced variability in strength. Consequently, these studies significantly decreased the likelihood and rate of capsular tears and other complications. Juhasz and Kurtz once again founded a company, LenSx Lasers, to commercialize their new invention. LenSx Lasers would eventually be acquired by Alcon for $316.5 million in 2010. Juhasz stayed on after the sale, serving as vice president of R&D for Alcon's LenSx division until 2016. During this time period, Juhasz also contributed to research in the field of corneal biomechanics and in the field of the treatment of keratoconus.

Worked examples

Example 1 — a first encounter with Tibor Juhasz

Start with the simplest possible case. Write down what Tibor Juhasz claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tibor Juhasz before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tibor Juhasz ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tibor Juhasz

In research
Tibor Juhasz appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Tibor Juhasz in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Tibor Juhasz is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century American scientists, 21st-century Hungarian scientists, Academic staff of the Budapest University of Technology and Economics, so understanding it makes those chapters shorter.
In everyday life
Look for Tibor Juhasz outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
