As part of the HDE approval, Addition Technology, the manufacturer of Intacs, has implemented an extensive training program in which each surgeon will be required to participate. The humanitarian device regulations were first established in October Humanitarian Use Devices HUDs are medical devices specially designated by the FDA for use in the treatment of fewer than patients per year with rare medical conditions.

It is up to the insurance company to determine the amount to be paid. This procedure involves placing the plastic inserts just beneath the surface of the eye in the periphery of the cornea. Topical anesthetic drops are used to numb the eye, and a clamp is used to hold the eye open throughout the procedure to prevent blinking. Instead of using mechanical cutting, some surgeons may use a laser to make the incision. During this time, the corneal layers are gently separated in a narrow circular band on the outer edge where the Intacs will be placed.

Once this insertion is completed, the small opening in the cornea is closed with a suture. Follow-up visits will be required to monitor the healing process and to evaluate the visual benefits of the procedure. Even after a successful procedure, glasses or contacts may be required. As with any surgical procedure, there are some risks, including infection. Some patients experience visual symptoms including difficulty with night vision, glare, halos, blurry and fluctuating vision.

Intacs are thin plastic, semi-circular rings inserted into the mid layer of the cornea. When inserted in the keratoconus cornea they flatten the cornea, changing the shape and location of the cone. The placement of Intacs remodels and reinforces the cornea, eliminating some or all of the irregularities caused by keratoconus in order to provide improved vision. This can improve uncorrected vision, however, depending on the severity of the KC, glasses or contact lenses may still be needed for functional vision.

Intacs Surgery Procedure This procedure involves placing the plastic inserts just beneath the surface of the eye in the periphery of the cornea. Provided by:.

What are corneal implants? Intacs can be very effective at changing the shape of the cornea and flattening the cone caused by keratoconus. Archives of Ophthalmology. January During the procedure, your surgeon creates a tunnel between layers of the corneal stroma , outside of the central optical zone.

Intacs cornea implants. What Are Intacs Corneal Implants Used For?

It is typically not correctable with glasses, requiring specialty contact lenses, or in severe cases if left untreated, a corneal transplant. During the consultation, we will ask you about your eye health history and your medications, and perform some tests.

Your personal Patient Counselor will help you throughout the process. Your Counselor can review insurance and payment options and schedule you for surgery and related appointments, such as post-operative exams. You will need to discontinue the use of contact lenses leading up to the procedure and start the use of eye drops.

Plan to be at the center for two to three hours the day of your procedure. This allows for pre procedure preparations including taking some medication in advance of your procedure. Keratoconus surgery is an outpatient procedure that takes about 15 minutes per eye. After numbing the eye and making a small laser tunnel in the periphery of the cornea your surgeon then inserts the Intacs segment.

The day of your procedure should be a day of rest. Your Patient Counselor will give you detailed post-operative instructions and eye drop regimen for your recovery. Belmont administers topical anesthetic eye drops, so you do not feel a thing for the duration of surgery. She then inserts the Intacs into the tunnel, choosing the Intacs level of thickness that will most effectively treat your unique vision problem.

Once the Intacs have been inserted, the procedure is complete. Intacs corneal implants are intended for long-term use. Only about 4 percent of Intacs patients are not satisfied with the results of their procedure. If you are in this small group, Dr.

Belmont can remove the Intacs implants, and either replace them with implants of a different thickness level or leave them out for good. In the latter case, your eyesight will return to how it was before the procedure within about three months. She can also replace your current Intacs with new ones if your prescription changes. If you suffer from keratoconus and can no longer wear contact lenses but are also not ready for corneal transplant surgery, Intacs might be right for you.

To find out if you are a suitable candidate for Intacs corneal implants, schedule an appointment with Dr. She will assess your situation and establish how far your keratoconus has progressed.

Depending on her assessment, you may be able to postpone or eliminate your need for a cornea transplant, with Intacs treatment. To schedule a comprehensive consultation with Dr. Belmont to determine your candidacy for Intacs treatment, please contact Belmont Eye Center by calling or by clicking here. Intacs Corneal Implants. Intacs for the Treatment of Mild to Moderate Keratoconus As keratoconus progresses, it makes it increasingly difficult to wear contact lenses and can ultimately impair vision significantly.

How Intacs Corneal Implants Work For the treatment of keratoconus, Intacs corneal implants work by flattening the cone, or the steep section of the cornea, to decrease vision distortions.

The Intacs Procedure The Intacs procedure is a minimally invasive, outpatient procedure that only takes about 15 minutes. Long-Term Vision Correction Intacs corneal implants are intended for long-term use. Postpone or Eliminate Your Need for a Cornea Transplant If you suffer from keratoconus and can no longer wear contact lenses but are also not ready for corneal transplant surgery, Intacs might be right for you.

Intrastromal Corneal Ring Segments (ICRS) - EyeWiki

Corneal thinning disorders often lead to protrusion, irregular astigmatism, and even perforation. Corneal ectatic disease may impair vision which can be restored by optical means such as glasses, soft, or rigid gas permeable contact lenses. However, severe cases may require correction or restoration of tectonic integrity of the cornea by surgical means. Although PKP can be very successful in this subset of patients, limitations of PKP can include high post-op cylinder, side effects from chronic topical steroids, corneal rejection, and recurrence of keratoconus in the donor cornea.

Intracorneal ring segments are a new modality in the treatment of corneal ectactic disorders. They are implanted in the deep corneal stroma to modify the corneal curvature. This procedure does not involve corneal tissue nor does it invade the central optical zone. The intrastromal ring concept was proposed by Reynolds in [3]. It was first evaluated as a treatment for myopia by Keravision. This technology was then adopted for the treatment of keratoconus.

In , the exemption was extended to include the 0. Colin et al were the first to report the use of these rings in keratoconus [5]. Intracorneal ring segments may be indicated for patients with low myopia The indications for implantation of ICRS are clear central cornea and contact lens intolerance. The insertion is performed under topical anesthesia. The pupillary center or the geometric center of the cornea is marked with a Sinsky hook.

This is the reference point. This is facilitated by intra-operative ultrasonic pachymetry. Pocketing hooks are used to create corneal pockets on each side of the radial incision. Then a semi-automated suction ring is placed around the limbus. After the suction is increased to mbar, two semicircular dissectors are advanced into the lamellar pocket by rotating clockwise and counterclockwise. Two semicircular tunnels are then created. The suction device is removed and the ring segments are inserted into the channels [7].

The infrared Nd:Glass laser wavelength nm can create channels at desired depth with a high degree of precision. Carrasquillo and Rabinowitz showed similar visual and refractive outcomes with either mechanical or laser-assisted procedures in keratoconus and post LASIK ectasia. There are no prospective randomized controlled studies with ICRS. This is associated with the low incidence of these conditions and there are no well-established surgical nomograms.

Different approaches in ICRS implantation in keratoconus were based on either spherical equivalent refraction or topographic values. In all of the studies in keratoconic eyes, statistically significant central flattening of the cornea were reported. ICRS reduced the sphere, cylinder and the spherical equivalent in keratoconus.

A regression in the spherical correction was observed in the medium and long-term. There are conflicting results in terms of reduction of corneal higher order aberrations, especially of the coma type. ICRS is also found to be useful in improving the contact lens tolerance for the residual refractive error.

Ertan et al showed a mean reduction of 1. Complications are rare as ICRS implantation is reversible, no corneal tissue is removed, and the central optical zone is not invaded. Intraoperative complications are epithelial defects at the keratotomy site, extension of the incision towards the central visual axis or towards the limbus, inadequate channel depth, superficial channel dissection, segment decentration, asymmetry of implants, and anterior chamber perforation.

Patients should be presented with realistic expectations to avoid disappointment. Well-designed, prospective, comparative studies are needed to establish accurate nomograms for ICRS implantation.
