Which Laser Is Used in Contoura?

Contoura procedure, also known as Contoura Vision or topography-guided LASIK (Laser-Assisted In Situ Keratomileusis), is an advanced refractive surgery technique. It corrects irregularities in the cornea and improves visual acuity. This scientific note aims to provide a comprehensive overview of the Contoura procedure, including its principles, methodology, clinical outcomes, and potential advantages over conventional LASIK techniques.

Contoura procedure utilizes a highly precise topography-guided ablation technique, which considers each patient’s unique corneal irregularities. It aims to optimize visual outcomes by customizing the laser treatment based on corneal topography measurements rather than relying solely on refractive errors.


Methodology-Which Laser Is Used in Contoura?

The Contoura procedure involves several key steps:


a. Preoperative Evaluation:
The patient undergoes a thorough assessment, including a detailed analysis of corneal topography, thickness, and refraction. Advanced diagnostic devices like corneal topographers create a high-resolution cornea map.


b. Topography-Guided Treatment Planning:
The acquired corneal topography data creates a personalized treatment plan. The system identifies irregularities and creates a customized ablation profile to correct both low- and high-order aberrations.


c. Laser Ablation:
The treatment plan transfers to the excimer laser. After that, it delivers precise laser pulses to reshape the cornea. The personalized corneal topography guides the ablation pattern, resulting in a more accurate and customized treatment.


d. Postoperative Care:
Patients are monitored postoperatively to ensure proper healing and to evaluate visual acuity outcomes.


Clinical Outcomes-Which Laser Is Used in Contoura?

Numerous studies have investigated the efficacy and safety of the Contoura procedure, reporting favorable visual outcomes and patient satisfaction. These studies have shown that Contoura can effectively reduce both refractive errors and corneal irregularities, leading to improved visual acuity and quality of vision.


Advantages over Conventional LASIK

The Contoura procedure offers several advantages over conventional LASIK techniques:


a. Personalized Treatment:
By utilizing corneal topography data, Contoura allows for a more customized treatment approach compared to traditional LASIK procedures, which primarily correct refractive errors based on manifest refraction.


b. Enhanced Visual Quality:
Contoura’s topography-guided ablation targets low- and high-order aberrations, leading to improved visual quality, reduced glare, and improved contrast sensitivity.


c. Reduction of Induced Corneal Irregularities:
The Contoura procedure has shown promising results in minimizing corneal irregularities induced during surgery, reducing the risk of postoperative visual disturbances.


d. Potential for Regression Prevention:
By addressing irregular corneal surfaces, the Contoura procedure may reduce regression risk and enhance visual outcomes’ long-term stability.

Thus Contoura procedure represents a significant advancement in refractive surgery, providing a personalized and precise approach to corneal reshaping. With its ability to target refractive errors and corneal irregularities, Contoura has demonstrated improved visual outcomes and patient satisfaction compared to conventional LASIK techniques. Further research and long-term studies are warranted to validate its effectiveness and assess its potential applications in various refractive conditions.
