In 1998, with its focus on keratoconus patients, the Ferrara Ring ™ presented itself as an alternative treatment to thousands of people who saw corneal transplantation as their only option.
In 1981, Dr. Paulo Ferrara, under the supervision of the late Professor Emir Soares, defended his Doctoral Thesis on the theme: Adaptation of Contact Lenses for Keratoconus ”, by Hospital São Geraldo, in Belo Horizonte.
Noting the high degrees of myopia and difficulties in adjusting to corrective lenses, he proposed the technique known today as Ferrara Ring Implant ™ (ICRS - Intra Corneal Rings Segments). The patent application was filed in 1987.
After 4 years of animal studies to evaluate the tolerance and behavior of the cornea to the implants, as well as to determine the shape and size, aiming at the creation of a nomogram, the first implants were performed in high myopic patients using the microkeratome keratectomy technique.
In 1994, he developed the tunneling technique that presented significant advantages over the previous technique, such as preservation of the corneal optic zone, shorter recovery time and easier implantation.
Improvement of nomogram.
In 2004, when Dr. Paulo Ferrara suggested the 4th generation of nomograms to choose positioning, segment size and thickness according to each keratoconus pattern observed. The choice of asphericity allowed the use of thinner segments with better and more predictable results.
RING PRODUCTION IN SPAIN
In 2006 Ferrara Ring segments started to be produced by AJL in Spain. The PMMA Yellow Anti Glare filter has brought more technology to the Ferrara ™ Ring segments and more patient comfort.
Today Ferrara Ophthalmics has accumulated more than two decades of technology transfer in the treatment of keratoconus. Approximately 600,000 implants have been performed worldwide.
