    Summary

    Oculopressure significantly reduced vitreous loss during cataract surgery, decreasing complications from 11% to 6.2%. Combining it with other methods offered minimal additional benefit but is still recommended for routine use.

    European review for medical and pharmacological sciences·2016

    Area of Science:

    • Ophthalmology
    • Surgical Techniques
    • Patient Safety

    Background:

    • Vitreous loss is a known complication during cataract surgery.
    • Preoperative interventions aim to minimize intraoperative complications.

    Purpose of the Study:

    • To compare the incidence of vitreous loss before and after implementing oculopressure.
    • To evaluate the efficacy of combined oculopressure, mannitol, and alphachymotrypsin in reducing vitreous complications.

    Main Methods:

    • Comparative study analyzing vitreous loss rates in cataract surgeries.
    • Introduction of oculopressure (Vörösmarthy method) as a preoperative intervention.
    • Evaluation of a combined approach including oculopressure, mannitol infusions, and alphachymotrypsin zonulolysis.

    Main Results:

    • Oculopressure reduced vitreous loss from 11% to 6.2%.
    • A combined approach (oculopressure, mannitol, alphachymotrypsin) showed a marginal decrease in vitreous complication rate from 6.2% to 5.5%.

    Conclusions:

    • Oculopressure is an effective method for reducing vitreous loss in cataract surgery.
    • Routine application of oculopressure, mannitol, and alphachymotrypsin is recommended despite minimal additional benefit in this study.
