    Summary
    This summary is machine-generated.

    Anterior keratotomy improved vision in 51% of myopic eyes initially. However, only 40% maintained 6/6 vision at three months due to corneal flattening, indicating limited long-term effectiveness.

    Area of Science:

    • Ophthalmology
    • Refractive Surgery

    Background:

    • Myopia management is a significant challenge in ophthalmology.
    • Anterior keratotomy has been explored as a surgical option for myopia correction.

    Purpose of the Study:

    • To evaluate the long-term efficacy and visual outcomes of anterior keratotomy in myopic eyes.

    Main Methods:

    • Analysis of 200 myopic eyes undergoing anterior keratotomy.
    • Postoperative follow-up included daily checks for two weeks, then weekly for four months, and monthly thereafter.

    Main Results:

    • Initial visual acuity improvement of 51% within the first week post-surgery.
    • At three months, only 40% of cases retained 6/6 visual acuity, linked to reduced corneal flatness.

  • Vision loss was proportional to the degree of corneal flattening; no changes in visual field, accommodation, or corneal thickness were noted.

    • Conclusions:

    • Anterior keratotomy shows initial visual improvement but limited long-term success in myopia correction.
    • The procedure is considered useful in only 40% of cases due to progressive corneal flattening and associated vision reduction.
