LASIK Eye Surgery Technology Revealed

LASIK (Laser-Assisted In Situ Keratomileusis) surgery continues to redefine ophthalmology, offering a transformative solution for refractive errors like myopia, hyperopia, and astigmatism. One of the key factors behind the success of LASIK is the ongoing technological advancements, with two standout innovations being the Wavelight laser and the Contoura Vision system. In this article, we explore the intricacies of LASIK technology, shedding light on the principles underlying the Wavelight laser and the groundbreaking Contoura Vision system.

LASIK, a revolutionary surgical procedure, enhances vision by reshaping the cornea, the transparent part of the eye. A laser creates a precise corneal flap, followed by another laser sculpting the corneal tissue to correct refractive errors.

Decoding the Wavelight Laser

Wavelight lasers mark a significant leap in LASIK technology, employing wavefront-optimized technology. Unlike traditional LASIK, which addresses basic vision aspects, wavefront-optimized treatments aim to maintain corneal asphericity by delivering more laser energy in the corneal periphery, reducing higher-order aberrations (HOA) associated with visual symptoms after conventional refractive surgery.

Introducing the Contoura Vision System

Contoura Vision, a revolutionary LASIK technology developed by Alcon, takes personalization to new heights. Integrating corneal topography and wavefront-guided technology, this system creates a detailed, individualized treatment plan.

Corneal topography maps the cornea’s curvature, providing insights into shape and irregularities. Combined with wavefront measurements, Contoura Vision produces a 3D map, enabling the laser to address not just refractive errors but also subtle corneal irregularities, enhancing visual outcomes.

The system’s proficiency in handling higher-order aberrations contributes to improved vision, especially in low-light conditions, with patients reporting sharper, clearer vision and reduced halos and glare.

Distinguishing Visx and Wavelight Lasers

Visx and Wavelight lasers, distinct brands of excimer lasers in LASIK surgery, differ in technologies and features. Wavefront technology, eye tracking systems, treatment speed, FDA approval, and treatment capabilities are factors differentiating them. Both brands boast FDA approval, with Wavelight often praised for precision and customization, while Visx has a long history of successful LASIK procedures.
