Healon GV, a new viscous Sodium hyaluronate preparation, simplifies and enhances safety in posterior segment eye surgeries like epiretinal membrane dissection. This study found no adverse effects, indicating its potential as an effective surgical aid.

Area of Science:

  • Ophthalmology
  • Biomaterials Science

Background:

  • Sodium hyaluronate preparations are used in posterior segment surgery.
  • Increased viscosity may improve efficacy in procedures like epiretinal membrane dissection.

Purpose of the Study:

  • To evaluate the safety and efficacy of Healon GV, a new high-viscosity Sodium hyaluronate preparation.
  • To assess Healon GV's utility in specific posterior segment surgical procedures.

Main Methods:

  • An open clinical study involving 24 adult patients undergoing posterior segment surgery.
  • Healon GV was used for membrane dissection, hemostasis, and retinal reattachment.
  • Postoperative monitoring included intraocular pressure, vitreous clarity, anterior chamber flare, and visual acuity over three months.

Main Results:

  • Healon GV facilitated simpler and safer surgical procedures.
  • No significant inflammatory reactions or increases in intraocular pressure were observed.
  • The preparation was effective in separating membranes, controlling bleeding, and repositioning detached retinas.

Conclusions:

  • Healon GV is a safe and effective viscoelastic agent for posterior segment eye surgery.
  • Its high viscosity offers advantages in managing complex retinal conditions.
