Abstract
Purpose :
Vitreoretinal (VR) surgery relies heavily on visualization, predominantly facilitated by wide-angle lens systems. Traditionally, these systems are bifurcated into contact and non-contact types, each with distinct advantages and limitations. Contact systems provide superior resolution and a broader field of view but necessitate a skilled assistant, while non-contact systems are independent of such assistance but offer limited visual quality.
Methods :
This study introduces a novel hands-free, wide-angle contact lens system for VR surgery, integrating the benefits of both contact and non-contact systems. It allows adaptation to popular non-contact systems like the Resight 700, offering flexibility between the two modalities. The system comprises an aspheric panfundoscopic lens and an adaptive lens holder ( fig.1) , designed for easy integration with existing surgical setups
Results :
The new system, compatible with the Resight 700, (fig.2) allows seamless switching between contact and non-contact modes. It provides a wide field of view with enhanced resolution and stereopsis, overcoming the optical limitations of non-contact systems. The design ensures minimal interference with surgical instruments and has been successfully utilized in 220 VR surgeries, including complex procedures, without any complications
Conclusions :
The innovative integration of contact and non-contact lens systems in VR surgery marks a significant advancement in surgical visualization. This hybrid system offers the wide field of view and high-resolution imaging of contact systems while mitigating the need for an assistant and reducing the risk of corneal injury. Its successful application in various surgeries underscores its potential to revolutionize visual capabilities in VR surgical practices, enhancing both surgeon experience and patient outcomes
