CORNEA RESTORE TREATMENT
PROSTHETIC SCLERAL LENSES
What's a Scleral Lens?
Prosthetic Scleral Lenses are medical devices for functional restoring of Cornea and Ocular Surface and could be considered as the maximum expression of ultra-specialistic contactology and ocular prosthetic. Due to its large diameter, a Scleral Lens can cover not only the total corneal extension but a part of anterior segment too and this permits to achieve different goals. Big experience and carefulness are required to fit properly this kind of lens and to control clinical-fitting conditions during the time, because of the many parameters to consider expecially in very complicated cases management.
CORNEA RESTORE Method is focused on fitting a Device with the caractheristics of an Artificial Ocular Surface, with the ability to give the best functional restore and the less invasivity on ocular tissues.
CORNEA VISUAL RESTORE
Thank to the unique features of Prosthetic Scleral Device, it's possible to recreate an artificial corneal surface to restore Visual Acuity, even in theses clinical cases with an extremely irregular morphology . CORNEA RESTORE Method permits to reduce the incidence of some optical aberrations and to obtain a controlled dynamics of the Device; in this way we can act where other kind of lenses could be failing, not reccomended or not safe.
MECHANICAL PROTECTION AND CORNEAL STRUCTURES LUBRICATION
A Scleral Lens can be easily compared to a "shell" that cover, enclose and protect corneal surface and part of scleral conjunctiva; this feature make this device a medical indication in each clinical case where we can found an excessive corneal vulnerability and where corneal tissues exposure could be problematic. In the same way, cause of the liquid solution that fill the lens, it's possible to restore corneal lubrication in all patients affected by dry eye disease to alleviate symptoms on ocular surface.
EPITHELIUM CORNEAL SURFACE RECONSTRUCTION
The protection and the constant lubrication due to the liquid solution in Scleral Device can encourage the epithelium reconstruction process in all those patients with persistent damages of the corneal surface due to pathological conditions, consecutive to surgical treatments or related to a prolonged mechanical stress (e.g. in Contact Lenses wearer).
Patient treated at Center. Right side picture shows the results after 90 days of Scleral Device wearing. Cornea has partially recovered its transparency and superficial structures regularity, becoming reflective again and giving an appreciable visual restore. We can notice a regression of neovascularization.
Two different patients treated at Center. To notice the strongly irregular profile of cornea. Prosthetic Scleral Device has "replaced" the vey extremely altered morphology of cornea, restoring effectively the visual function.
Patient treated at Center. Paziente trattato presso il Centro. Scans demonstrate the complete recovery of epithelium tissue after 60 days since the beginning of treatment with Prosthetic Scleral Lens. The patient, affected by Keratoconus, showed a drastic reduction of epithelium tissue consecutive to RGP lenses-related abrasions.
When to fit a Scleral Lens?
First of all, it's necessary to underline that a Prosthetic Scleral Lens is a medical indication and a rehabilitative option intended for those extreme cases where other surgical or therapeutic possibilities don't exist or have to be delayed.
Frequently it's possible to fit a Scleral Device as an alternative to Cornea Transplant o as a temporary solution for delaying surgical act.
In some cases a Scleral Lens fitting is required when other tipologies of lenses result to be inadequate or dangerous cause of fitting complications or bad side effects on corneal tissues.
Among the clinical conditions that can benefit from Prosthetic Scleral Lenses fitting, we can find the following:
Corneal Degenerations in every stage of evolution (Keratoconus, Pellucid Marginal Degeneration, Terrien Marginal Degeneration)
Complications and/or ourcomes Post Corneal Transplant (Keratoplasty)
Severe diseases of Ocular Surface ( Stevens-Johnson Syndrome, Lyell Syndrome, Cicatricial Pemphigoid, Sjogren Syndrome, Corneal Anesthesia, Salzmann Degeneration, Rosacea Keratitis, Recurrent Ulcerative Keratitis)
Complications Post Contact Lenses wearing
Complications Post Refractive Surgery
GVHD Graft Versus Host Disease
Corneal Trauma outcomes
CORNEA RESTORE Method
CORNEA RESTORE Method represents the desire to create a fitting procedure intended for patients with extremely delicate clinical conditions of cornea; in these cases our main goal is to respect and protect compromised corneal tissues in long term period reducing the risks of complications.
The definition of this method has been made possible thanks to studies and monitorings of Devices dynamics in time in relation to the features of each area of ocular surface for several kind of clinical conditions.
This permits to understand the evolution of the dynamics of Scleral Lenses according to the characteristics of each patient, allowing to completely customize the Prosthetic Devices fitting and significantly reducing its invasiveness.
