Intacs Corneal Inserts: A Game-Changer for Keratoconus and Nearsightedness Correction

INTACS CORNEAL INSERTS: A REVOLUTIONARY TREATMENT FOR KERATOCONUSImagine living with a condition that gradually deteriorates your vision, making it difficult to carry out daily tasks. This is the reality for individuals living with keratoconus, a progressive eye disease that affects the shape and stability of the cornea.

Fortunately, there is hope in the form of Intacs corneal inserts. In this article, we will explore how Intacs can treat keratoconus, their FDA approval, and other treatment options available.

Intacs Corneal Inserts – A Breakthrough in Keratoconus Treatment

Keratoconus occurs when the cornea, the clear front surface of the eye, thins and bulges into a cone shape instead of having a normal rounded shape. This can cause irregular astigmatism, nearsightedness, and visual distortion.

Intacs corneal inserts are a revolutionary treatment designed to address these issues. These inserts are small, crescent-shaped pieces of medical-grade plastic that are inserted into the cornea.

Their purpose is to reshape the cornea, improving vision and reducing the need for glasses or contact lenses. By providing structural support, Intacs stabilize the cornea and enhance its regular shape.

FDA Approval and Other Treatment Options

The use of Intacs corneal inserts for the treatment of keratoconus was approved by the Food and Drug Administration (FDA) in 1999. This approval means that Intacs have undergone rigorous clinical trials and met the necessary safety and effectiveness standards.

While Intacs have proved to be a successful treatment option for many individuals with keratoconus, it’s important to note that they are not the only option available. Other treatments include corneal cross-linking, a procedure that strengthens the cornea using UV light and riboflavin, as well as specialty contact lenses designed to improve vision and increase comfort.

How Intacs Work – Restoring Vision Through Precision

Intacs work by reshaping the cornea, improving its curvature and visual quality. The process begins with a comprehensive eye examination, where the ophthalmologist determines the severity of keratoconus and evaluates a patient’s suitability for Intacs.

During the procedure, a small incision is made in the cornea, and the Intacs inserts are placed. The precise positioning of the inserts is crucial, as it determines the desired corneal shape.

Once in place, the Intacs exert gentle pressure on the cornea, flattening the cone shape. This process restores the cornea to a more regular curvature, leading to improved vision.

Safety and Potential Side Effects – Prioritizing Patient Well-being

Intacs have been demonstrated to be safe and effective in treating keratoconus. However, as with any medical procedure, there are potential side effects to be aware of.

These include temporary dryness, glare, halos, and difficulties with night vision. These side effects are generally mild and resolve within a short period as the eyes adjust to the inserts.

It is vital for individuals considering Intacs to consult with a trusted ophthalmologist who can assess their eye health and discuss potential risks and benefits. Each case is unique, and the doctor can provide personalized information to help make an informed decision.


Living with keratoconus can be challenging, but thanks to technological advancements and FDA-approved treatments like Intacs corneal inserts, individuals with this condition can find relief. By reshaping the cornea and improving vision, Intacs provide hope and improved quality of life for those affected by keratoconus.

Procedure Process, Anesthesia, and Recovery Time – A Precise Technique

The process of having Intacs corneal inserts inserted is a relatively simple and precise technique. The procedure begins with the administration of local anesthesia to numb the eye, ensuring that the patient remains comfortable throughout the process.

General anesthesia is typically not required, as patients can remain awake during the procedure. Once the eye is numbed, the ophthalmologist makes a small incision in the cornea, creating a tunnel-like pocket.

This pocket is where the Intacs inserts will be placed. The inserts are carefully guided into the pocket using a specialized instrument, ensuring correct placement within the cornea.

After the inserts are successfully positioned, the incision is closed with a tiny suture or using a self-sealing technique. The entire process typically takes around 15 to 20 minutes per eye.

Patients are often advised to arrange for someone to drive them home after the procedure, as their vision may be temporarily blurry. Recovery time after Intacs insertion is relatively quick.

Most patients experience improved vision within the first few days, with their vision stabilizing over the following weeks. It is common for patients to experience some mild discomfort, such as temporary dryness or scratchiness, during the healing process.

These symptoms can be managed with prescribed eye drops and typically resolve within a few weeks.

Vision Improvement and the Need for Additional Correction – A Worthwhile Investment

Intacs corneal inserts have been shown to significantly improve vision in individuals with keratoconus. While the inserts alone can improve visual acuity for many patients, some may still require additional vision correction in the form of glasses or contact lenses for optimal vision.

However, the amount of additional correction needed is often significantly reduced after Intacs placement. The goal of Intacs is to improve the corneal shape enough to reduce astigmatism and nearsightedness caused by keratoconus.

While this treatment does not guarantee perfect vision or completely eliminate the need for corrective eyewear in all cases, it often leads to a substantial improvement in visual acuity. Many patients are able to achieve functional vision without the reliance on thick glasses or specialty contact lenses.

It is important for patients to have realistic expectations regarding the results of the Intacs procedure. Depending on the severity of keratoconus, some individuals may still require low-powered glasses or contact lenses for certain activities such as reading or driving at night.

However, the reduction in vision correction needed is often a significant improvement in comparison to their pre-Intacs vision.

Combination Treatment with Corneal Cross-Linking – Strengthening the Cornea

In some cases, a combination treatment approach involving Intacs corneal inserts and corneal cross-linking may be recommended. Corneal cross-linking is a procedure that uses UV light and riboflavin to strengthen the cornea, slowing down or halting the progression of keratoconus.

Corneal cross-linking is typically performed before the insertion of Intacs, as it stabilizes the cornea and prepares it for reshaping. The cross-linking procedure involves applying riboflavin eye drops to the cornea, followed by exposure to UV light.

The UV light activates the riboflavin, which creates bonds within the cornea, increasing its strength and stability. By combining Intacs with corneal cross-linking, patients can experience a more comprehensive treatment approach.

The cross-linking procedure strengthens and stabilizes the cornea, while the Intacs reshape it to improve vision. This combination approach has shown promising results in clinical trials and has become a preferred treatment option for many ophthalmologists.

Clinical Trial Results and Success Rates – Promising Outcomes

Numerous clinical trials have been conducted to evaluate the safety and effectiveness of Intacs corneal inserts for the treatment of keratoconus. These studies have consistently shown positive outcomes and high success rates.

One study published in the Journal of Cataract & Refractive Surgery followed patients with keratoconus who underwent Intacs insertion. The study reported that 85% of the patients experienced improved uncorrected visual acuity, and 89% experienced improved best-corrected visual acuity.

Additionally, the study noted that 96% of patients achieved stabilization or improvement in their keratoconus over a three-year follow-up period. Another clinical trial, published in the American Journal of Ophthalmology, found that 88% of patients who received Intacs implants experienced improved vision and achieved a reduced reliance on glasses or contact lenses.

Similar positive results have been reported in various other clinical trials, further highlighting the effectiveness of Intacs as a treatment option for keratoconus.


In conclusion, Intacs corneal inserts offer a breakthrough treatment for individuals with keratoconus. By reshaping the cornea and improving its curvature, Intacs provide a means of improving vision and reducing the reliance on glasses or contact lenses.

With the potential for a quick recovery and promising success rates, Intacs, alone or in combination with corneal cross-linking, have changed the lives of many who struggle with keratoconus.
