Introduction
Since 1858, HAAG-STREIT SURGICAL has been at the forefront of developing innovative and reliable products, driven by visionary thinking and a fascination with technology. The TOCULAR device is designed to enhance the quality of life by improving the precision of toric intraocular lens (IOL) implantation.

Product Overview
The TOCULAR is a rotatable wide-angle ocular with an integrated reticle, specifically designed for the precise angle alignment of toric IOLs during implantation. It features:

• Ocular parameters: 10x 21B
• Reticle markings: Large (180° steps), Medium (10° steps), Small (5° steps)
• Rotation capability: +/-180°
• Positioning: Left or right ocular

The device allows for an IOL alignment accuracy of better than +/- 2°.

Working Principle
Pre-operative Work: The astigmatic angle is determined using a keratoscope or biometer, such as the Haag-Streit LENSTAR LS 900. The eye is then ink-marked with a sterilizable pre-marker, like the Davis pre-marking system.
During Surgery: After IOL implantation, the microscope zoom is adjusted to display the ink-marking. The TOCULAR's reticle is rotated to align with the ink-marks, allowing the IOL to be positioned accurately using the reticle's medium and small markings.

Technical Specifications
The TOCULAR is equipped with a sterilizable knob for manual rotation of the reticle, ensuring clear visibility in the center of the visual field.

Conclusion
The TOCULAR device by HAAG-STREIT SURGICAL offers a precise and reliable solution for the alignment of toric IOLs, enhancing surgical outcomes and patient satisfaction.
