Lens CGVL - Good

Categories: Ophtalmology


The CGVL lens from Haag-Streit is a vitrectomy contact lens designed to enhance laser performance by increasing the laser beam angle and enlarging the beam diameter. This effectively reduces the laser focal point by minimizing spherical aberrations and coma.

Description

The Haag-Streit CGVL Lens - Enhancing Laser Performance in Vitrectomy.

This special lens is designed to increase the angle of the laser beam, thereby enlarging the beam diameter over areas outside of the focus while reducing the laser focal spot size. This reduction in laser focal spot size is achieved by minimizing spherical aberrations and coma.

The design of the CGVL Lens is optimized to ensure optimal results. The center of curvature of the entrance surface, which is free from spherical aberrations or coma, coincides with the center of curvature of the retina, allowing for precise focusing. Additionally, the other aplanatic point of the entrance surface is positioned on the retina to ensure exceptional performance when using the laser.

The CGVL Lens offers a dioptric power of -33 D in air, making it a high-precision tool for ophthalmic laser procedures. This dioptric power allows for precise adjustments for personalized and effective treatments.

By using the CGVL Lens, eye health professionals can achieve optimal laser focusing, thereby reducing the risk of undesirable aberrations and ensuring high-quality treatment outcomes.
