    Using hyaluronate sodium during extracapsular cataract extraction significantly reduces endothelial cell loss compared to traditional methods. This technique offers better protection for the corneal endothelium.

    Area of Science:

    • Ophthalmology
    • Surgical Techniques
    • Biomaterials

    Background:

    • Extracapsular cataract extraction (ECCE) is a common procedure.
    • Potential complications include cystoid macular edema and corneal endothelial damage.
    • Protecting the corneal endothelium is crucial for surgical success.

    Purpose of the Study:

    • To evaluate the efficacy of 1% hyaluronate sodium (Healon) as an irrigating vehicle during ECCE.
    • To compare the protective effects of hyaluronate on the corneal endothelium versus balanced salt solution (BSS).

    Main Methods:

    • A comparative study involving 40 eyes undergoing ECCE.
    • Group 1 (20 eyes): Traditional ECCE using BSS.
    • Group 2 (20 eyes): ECCE using 1% hyaluronate sodium as the irrigating vehicle.

    Main Results:

    • Postoperative endothelial cell counts were significantly higher in the hyaluronate group.
    • Hyaluronate's high viscosity potentially prevented posterior capsule rupture.
    • Hyaluronate demonstrated a protective coating effect on the corneal endothelium.

    Conclusions:

    • 1% hyaluronate sodium is a safe and effective irrigating vehicle for ECCE.
    • Using hyaluronate significantly reduces corneal endothelial cell loss.
    • This technique may improve outcomes in cataract surgery.
