Discover cTen®

The most advanced Trans-PRK available

“No eye is equal to another”
This indisputable statement is the foundation of our research into the customization of corneal surgery, that led to the introduction of cTen® procedure. cTen® customizes your treatment to optimize the quality of vision, minimizing invasiveness and reducing the risk of complications for the patient.

“Reaching your destination requires knowing your starting point”
The iVis Suite™, the platform conceived for the execution of cTen®, integrates the leading diagnostic devices Precisio® and pMetrics®, to acquire, with unmatched accuracy , the data needed to improve the vision and treat even what was previously classified as untreatable.

cTen®, our proprietary, customized, no-touch procedure, blends the core principles of the iVis philosophy based upon respecting your eyes!

cTen® philosophy

cTen transPRK femto touch free

cTen® (Customized, Trans-Epithelial No-Touch) is our exclusive refractive and therapeutic surgery procedure

cTen® is Customized to each eye, to optimize your vision with Low Invasiveness of the treatment.

cTen® is Trans-epithelial and, unlike LASIK, gently re-shapes only the anterior surface of the cornea, in a fully automatic and No-touch procedure.

The laser will remove, in one single step, only the needed amount of epithelium and stroma, according to the planned ablation profile to optimize your vision. This smooth process allows the execution of a fully No-Touch laser procedure, Painless during the treatment and free from complications.

No-Touch means that the restoration of your vision is Fast and fully-automatic. Thus cTen® is Safe, as it eliminates all manipulations of your eye that causes intraoperative discomfort and are an unpredictable source of intraoperative risks that could affect your final quality of vision.

In this way, your eyes are respected with the lowest possible interference!

cTen® can bring solutions to a wide variety of ordinary refractive disorders, such as Myopia, Hyperopia, Astigmatism Presbyopia. Additionally, cTen® can effectively treat more complex refractive disorders, such as mixed or irregular astigmatism, tilting and high-order aberrations always minimizing invasiveness.

cTen® can address complex refractive disorders, complications induced by previous corneal surgeries, such as decentred ablations and central islands, as well as complications induced by a trauma such as corneal scars, or by congenital errors .

The superior therapeutic capabilities of cTen® make also possible to treat degenerative corneal pathologies, like Keratoconus, thanks to innovative techniques which combine trans-epithelial corneal regularization and cross-linking, or Pterygium, thanks to a customized corneal-scleral regularization.

To date, more than 500,000 patients have recovered their ideal vision thanks to cTen®, in some of the worldwide most prestigious hospitals that have embraced the iVis philosophy, thus eliminating the risks associated with LASIK and its complications. To fully discover the capabilities of cTen® and its scope, we invite you to contact your closest iVis Centre.

Although cTen® is a patient-friendly and intraoperatively no-touch procedure you may experience post-operatively some degree of discomfort or even pain depending upon your own sensitivity. This pain normally is well managed with the drugs prescribed by your Ophthalmologist and disappears by the second day after surgery.

Postoperative vision may fluctuate until the complete stabilization that generally occurs within 20 days after surgery.

cTen® was developed to offer permanent results and to minimize the risk of overcorrection or undercorrection. However, even if rarely, due to a possible different corneal response to the laser ablation, unexpected overcorrection or undercorrection may result.

Corneal healing after surgery may vary from patient to patient. This variation possibly may impact the final visual result. For example, a regression of the refractive outcomes may occur soon after the treatment, or within several months.

cTen® was created to minimize all possible complications associated with refractive surgery by reducing invasiveness and automatizing the execution of the treatment. However, as a surgical procedure, cTen® may, even if rarely, present complications and varying results from patient to patient.

Postoperative vision may fluctuate until complete stabilization that generally occurs within 20 days after surgery.

cTen® does not require the creation of a corneal flap, like in LASIK treatment. Therefore, the risk of insurgence of all visual complications commonly associated with the flap is absent.

Some patients, because of healing may experience, rarely, clouded vision to some degree, often referred to as haze. In these cases, haze normally clears within 12 months, with the help of some eyedrops prescribed by your Ophthalmologist. Haze is often linked to UV exposures, for example sunbathing. Therefore, it is recommended to avoid direct sunlight exposure for a minimum of six months after your cTen® treatment and to wear sunglasses with a total UV-filter.

Other rare visual complications may include halos, a shimmering circle around light sources such as car headlights, glare or increased sensitivity to bright light, and/or double vision (diplopia), described as “ghosting” around an object.

If any of these unexpected outcomes and/or complications occur, your cTen® Ophthalmologist will support you discussing and treating them.

My Surgery day

before, during and after my Surgery

If you have decided in favour of the cTen® low invasiveness approach, you will have to book a consultation with one of the Ophthalmologists that use the iVis Suite™. You will find the closest one in the section “Find your cTen® Surgeon″.

During the consultation, your Ophthalmologist will acquire your Real Shape™ corneal maps with Precisio®, and your Ideal Pupil™ with pMetrics®. Your visual defect will be measured and other necessary checks for cTen® will be performed.

Once your suitability has been confirmed, your Ophthalmologist will design on his computer your customized cTen® plan ahead of the surgery day.

As opposed to a standard LASIK procedure, your cTen® takes on average 30 seconds, thus minimizing your time in the surgery room.

You will be asked to lie on the patient bed under the iRes™ laser arm. eye-drops will be placed by your Ophthalmologist in the eye to be treated, ahead of placing an eyelid speculum, a tiny metal clip, to ensure your eyelid will remain open during treatment.

Then, laser pulses will quickly and automatically reshape the cornea with micrometric precision to achieve your customized Ideal Shape™, the optimal corneal profile planned by your Ophthalmologist with the CIPTA® software.
During the surgery, you will be asked to keep focusing on a red light, and in case you move your eye or your head, the eye-tracker system of iRes™ will follow the eye movements and adjust the direction of the laser beam with a real-time response.

Once completed, after about 30 seconds , some eye-drops will be placed in your eye together with a protective contact lens, and your Ophthalmologist will remove the speculum.

Normally, you will be asked to wait in the clinic for at least 30 minutes after the surgery, and you will be given a prescription for the drugs to be taken in the days following the treatment.

Patients normally are advised to come accompanied by a relative or a friend on the day of your cTen® treatment, as your Ophthalmologist will almost certainly ask you to refrain from driving a car for a minimum of 72 hours.

After cTen®, you may experience a moderate discomfort, like sand in your eyes, with decreasing intensity for around 48 hours after the treatment. Make sure to follow carefully your cTen® post-treatment care plan, as advised by your Ophthalmologist.

You may expect to go back to work within three days and your vision will improve gradually in the next 20 days after the treatment.

Please make sure to attend the follow-up appointments scheduled by your Ophthalmologist to ensure proper stabilization of your vision.
