    Summary

    A small-incision technique for phacoemulsification and intraocular lens (IOL) implantation resulted in lower postoperative astigmatism and faster visual recovery compared to a larger incision. This demonstrates the benefit of minimally invasive cataract surgery.

    Area of Science:

    • Ophthalmology
    • Surgical Techniques
    • Refractive Error Correction

    Background:

    • Phacoemulsification with intraocular lens (IOL) implantation is a standard cataract surgery.
    • Postoperative astigmatism can affect visual outcomes.
    • Minimally invasive surgical approaches are being developed to improve patient recovery.

    Purpose of the Study:

    • To compare the incidence of postoperative astigmatism and visual rehabilitation between two phacoemulsification techniques.
    • To evaluate the impact of incision size on refractive outcomes after IOL implantation.

    Main Methods:

    • Two groups of patients underwent phacoemulsification and IOL implantation (IOGEL, Alcon).
    • Group 1: 6.5 mm scleral pocket incision.
    • Group 2: 3.5 mm incision using a novel instrument.

    Main Results:

    • Group 2 patients exhibited significantly lower postoperative astigmatism.
    • Refractive stability was achieved earlier in Group 2 compared to Group 1.
    • Minimal refractive changes were observed by three weeks postoperatively in most patients.

    Conclusions:

    • A small-incision technique (3.5 mm) for phacoemulsification and IOL implantation leads to reduced postoperative astigmatism.
    • Minimally invasive cataract surgery accelerates visual rehabilitation.
    • The new instrument facilitates smaller incisions, improving patient outcomes.
