FERRARA RING ™
Created by Dr. Paulo Ferrara in 1987 for the correction of high myopia.
In 1996, with the advent of Excimer Laser, the Ferrara Ring™ started to be employed in the treatment of patients with keratoconus.
In 1998, Dr. Paulo Ferrara taught the first Course on Intrastromal Corneal Ring Segment (ICRS) Implantation for the correction of keratoconus.
Nowadays, this technology is present in 87 countries amounting to over 600.000 eye implants.
FEATURES
Manufactured with PMMA, it is fully / well tolerated by the cornea.
Available in two models, the Premium Ferrara RingTM is manufactured with Yellow PMMA (Polymethyl methacrylate – the same material used in intraocular lenses), thus providing an additional filter to blue light, which is predominantly nocturnal and can cause haloes and glare.
Throughout over 30 years of existence, knowledge built up on the mechanism of action undergone by the rings allied to new semiologic techniques and the use of Femtosecond Laser for ring implantation made the method safer and more predictable.
HISTORY FERRARA RING ™
INDICATION FOR USE
In addition to Keratoconus treatment, the Ferrara Ring™ is also indicated for the following ectasias:
Keratoconus patients who present with evident progression are the best candidates for the implant of Ferrara Ring™ segments.
In 85% of the cases, Ferrara Ring™ implants stabilize keratoconus evolution and allow proper vision correction with the use of contact lenses or glasses.
Improved quality of life is reported by most of the patients who have undergone Ferrara Ring™ implants.
Contact lens intolerance constitutes a formal indication for ring implant, in so far as patients do not achieve good visual acuity by wearing glasses, thus becoming unable to perform their habitual tasks.
Ferrara Ring™ implants can be combined with the adaptation of rigid, gelatinous or scleral contact lenses, with the correction of post corneal transplant astigmatism and with Crosslinking.
POST-KERATOPLASTY ASTIGMATISM
POST LASIK ECTASIA
PELLUCID MARGINAL DEGENERATION (PMD)
Characterized by progressive peripheral thinning in the inferior region of the cornea, PMD causes high irregular astigmatisms, which makes it difficult to correct eyesight with the use of contact lenses or glasses.
PMD is more common in young people and 20-to-30-year-old adults; there is no preventive treatment for the disease, its progression is slow and continuous. Constanteye rubbing can aggravate DMP and must be avoided.
Ferrara Ring™ implantation reduces irregular astigmatism and facilitates vision rehabilitation with the help of corrective lenses.
ADVANTAGES
NOMOGRAM
Given the individuality of each keratoconus case, the nomogram, or the way to use the Ferrara Ring™, is a suggestion for choosing segments and surgical planning. The nomogram derives from statistics of implants performed in the past 20 years.
After observing results, we currently use Asphericity as the main parameter for indicating position, arc size and thickness of Ferrara Ring™ segments.
MECHANISMS OF ACTION
- Studies have additionally shown the following:
- Interruption or delay of Keratoconus evolution
Reduction of related symptoms such as itching, photophobia and pain and/or ocular discomfort; - Decrease in the depth of the anterior chamber as observed via Ultrasound Biomicroscopy;
- Flattening
Central and peripheral flattening with improvement of asphericity; - Corneal Surface Regularization
by means of a “couppling” effected caused by segment shape; - UCVA
No correspondence has been found between postoperative UCVA and residual ametropia. At times, improvement of visual acuity has been observed while coexisting with residual refractive errors; - Prismatic Effect
The prismatic effect generated by the triangular cross section eliminates halos and glare which can be caused by small orthosis diameter; - Yellow Filter
The yellow filter prevents blue light from entering human eyes thus reducing sensation of halos and nocturnal glare/night reflections.
