Video Resources for OVD-Free ICL Implantation

I cannot provide video links or locate specific videos, as I am a text-based medical consultant without the ability to search or access video databases, YouTube, or other multimedia platforms.

However, I can guide you on what to search for and provide the technical details of the procedure based on the available evidence.

What to Search For

Search terms to use on medical video platforms:

  • "OVD-free ICL implantation technique"
  • "Viscoelastic-free implantable collamer lens surgery"
  • "Non-OVD EVO-ICL implantation"
  • "BSS-only ICL implantation technique"

Recommended platforms for surgical videos:

  • JCRS (Journal of Cataract & Refractive Surgery) video library
  • ASCRS (American Society of Cataract and Refractive Surgery) video archives
  • EyeTube.net
  • YouTube channels of refractive surgery specialists
  • Manufacturer training materials (STAAR Surgical for ICL)

Technical Overview of the OVD-Free Technique

The OVD-free technique has been validated as safe and effective for ICL implantation 1, 2, 3.

Key Technical Steps:

Anterior chamber maintenance:

  • Balanced salt solution (BSS) is used instead of viscoelastic to load the ICL and maintain the anterior chamber 1
  • The technique eliminates OVD-related complications, particularly early postoperative IOP elevation 2, 3

Surgical efficiency:

  • The OVD-free technique significantly reduces surgical time compared to conventional OVD-based procedures 1, 2
  • Success rates of 94.5% have been reported for the pure viscoelastic-free technique 3

Safety profile:

  • No significant differences in visual outcomes, endothelial cell density, or percentage of hexagonal cells compared to OVD technique 1
  • Mean endothelial cell density loss was only 1.9% at 2 years with OVD-free technique 1
  • IOP remains significantly lower in the early postoperative period (1-3 hours) with OVD-free technique 2

Critical Advantages:

  • Reduced IOP spikes: The non-OVD technique completely eliminates viscoelastic-related IOP elevation in the immediate postoperative period 2, 3
  • Faster recovery: Corneal densitometry values are significantly lower with OVD-free technique, indicating less corneal trauma 2
  • Cost-effectiveness: Eliminates the cost of viscoelastic agents 1

Common Pitfalls to Avoid

When learning this technique, be aware that:

  • Approximately 5.5% of cases may require conversion to using viscoelastic for lens alignment 3
  • Maintaining adequate anterior chamber depth with BSS alone requires careful technique 1
  • The learning curve exists, with initial success rates around 55% improving with experience 2
