Viscoelastic fluids protect endothelial cells better than air during intraocular lens implants. Hydroxypropylmethylcellulose (HPMC) is a cost-effective alternative to sodium hyaluronate for this purpose.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Biomaterials

Background:

  • Posterior chamber intraocular lens (PCIOL) implantation is a common surgical procedure.
  • Maintaining corneal endothelial cell viability is crucial for successful PCIOL outcomes.
  • Current endothelial cell protection methods vary, necessitating comparative studies.

Purpose of the Study:

  • To compare the efficacy of three different endothelial cell protection strategies during PCIOL implantation.
  • To evaluate viscoelastic fluids versus air for protecting endothelial cells.
  • To assess the cost-effectiveness of different viscoelastic agents.

Main Methods:

  • A randomized controlled trial was conducted.
  • Patients undergoing PCIOL implantation were assigned to receive one of three endothelial cell protection methods.

  • Endothelial cell counts were assessed post-operatively.

    • Main Results:

    • Viscoelastic fluid demonstrated superior endothelial cell protection compared to air.
    • No statistically significant difference in endothelial cell protection was observed between sodium hyaluronate and hydroxypropylmethylcellulose (HPMC).
    • The high cost of sodium hyaluronate was noted as a significant factor.

    Conclusions:

    • Viscoelastic fluids are recommended over air for endothelial cell protection during PCIOL surgery.
    • HPMC presents a viable, cost-effective alternative to sodium hyaluronate for endothelial cell protection.
    • A manufacturing technique for HPMC is provided to facilitate its use.
