    Summary
    This summary is machine-generated.

    Keratophakia surgery for aphakia correction achieved good visual acuity in most patients. This extraocular procedure is a viable option for unilateral aphakia and young patients despite its complexity.

    Area of Science:

    • Ophthalmology
    • Corneal Surgery

    Background:

    • Surgical aphakia, a condition of lens absence post-surgery, presents challenges in visual rehabilitation.
    • Keratophakia, an intraocular lens implantation procedure, offers a surgical solution.

    Purpose of the Study:

    • To evaluate the visual outcomes and complications of keratophakia in patients with surgical aphakia.

    Main Methods:

    • A retrospective analysis of 23 patients who underwent keratophakia for surgical aphakia.
    • Visual acuities, refractive errors, and astigmatism were assessed over a 12 to 48-month follow-up period.

    Main Results:

    • 17 out of 23 patients achieved visual acuity of 20/40 or better.
    • Average residual overrefraction was 1.87 +/- 1.79 diopters, with increased astigmatism of 1.70 +/- 1.33 diopters.

  • Complications were generally minor, with few requiring lenticule removal or further surgery.

    • Conclusions:

    • Keratophakia provides good visual results for surgical aphakia correction.
    • Despite procedural complexity and recovery time, it is a preferred alternative to secondary intraocular lens implantation, especially for unilateral aphakia and young patients.
