Hace poco un equipo de investigadores españoles era galardonado por sus trabajos en el desarrollo de una lente de contacto que elimina la hipermetropía sin cirugía. Este blog se felicita de ver como los trabajos de nuestros investigadores alcanzan una resonancia mundial y aparecen en medios tan prestigiosos como la Web www.sciencedaily.com.
Este artículo no va a describir sus trabajos, en el caso de no haberlos leído podréis encontrar un exhaustivo resumen en el siguiente link: Diseñada en la Escuela de Óptica y Optometría de la UPC una lente de contacto que elimina la hipermetropía sin cirugía.
Yo estoy convencido desde hace mucho tiempo que la Investigación y el Desarrollo son el mejor medio para que los países y los sectores progresen. Espero que a este trabajo le sigan muchos otros, tanto en España como en toda América, para que los optometristas hispanos vayan convirtiéndose en referencias dentro del sector del cuidado de la visión.
Aquí os dejo la noticia en inglés:
Contact Lens Capable of Correcting Hyperopia Without Surgery
Jaume Pauné, a graduate of the Master’s Degree in Optometry and Vision Sciences at the UPC-Barcelona Tech’s College of Optics and Optometry, has designed an innovative new contact lens that will improve the vision quality of thousands of people without surgery.
The Spanish Association of Opticians and Optometrists has granted its National Award to Mr. Pauné for his innovative work in this field.
Pauné’s design is the first contact lens capable of correcting hyperopia without refractive surgery by means of corneal reshaping, also known as orthokeratology or ortho-K. This technique uses rigid gas-permeable contact lenses to reshape the cornea to correct vision defects such as myopia, stigmatism and mild to moderate hyperopia without surgery. Each patient is fitted with unique lenses that are custom-made for his or her eyes.
Perfect vision, without surgery
For the sake of comfort, the patient wears the contact lenses only at night. The lens works by applying pressure to the tear film that coats the outside of the cornea. This pressure changes the shape of the cornea by about 20 µm, or about half the width of a strand of human hair. In the morning, the patient removes the lenses and is able to see perfectly. The results are the same as with refractive surgery, but are temporary. These new contact lenses, developed as part of a master’s thesis by Jaume Pauné, are being sold at an initial price of €1000, which includes the cost of designing unique lenses to fit each cornea, and €400 for annual replacement lenses.
The lenses are being marketed in collaboration with Atenas Vision, the distributor for Spain and Portugal, and the French laboratory Precilens, which manufactures the lenses under the name PauneLens.
Jaume Pauné developed this innovative new contact lens using existing ortho-K technology. In 2005, at an international contact lens conference in the United States, Pauné saw the presentation of the first ortho-K lens to be developed for, which ultimately was never introduced on the market. His interest piqued, Pauné began experimenting with the idea of manufacturing such a lens. In 2008, he enrolled in the UPC-Barcelona Tech’s Master’s Degree in Optometry and Vision Sciences, which required him to complete a master’s thesis.
In the course of his research for the thesis, he reviewed the literature and decided to design and manufacture a new model of contact lens, which he tested on ten people. One of these patients, an individual determined to find a solution to ongoing vision problems, tried six different models of the lens, each for a period of one week. With this patient, Pauné found the key to developing the first effective contact lens for hyperopia. In the process, he discovered that his technical and scientific principles were different from those of models used for myopia.
