Hexagonal keratotomy effectively corrected mild hyperopia (3.50 D or less) in a small patient group. However, due to variable outcomes and potential complications, this procedure is no longer recommended.

Area of Science:

  • Ophthalmology
  • Refractive Surgery

Background:

  • Presents a limited, positive experience with hexagonal keratotomy for hyperopia.
  • Highlights the use of this surgical technique in 1993.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of hexagonal keratotomy for hyperopia correction.
  • To assess the need for enhancement procedures and their impact on refractive outcomes.

Main Methods:

  • Eighteen eyes of 12 patients underwent hexagonal keratotomy using an open pattern.
  • Surgical planning was based solely on refractive data.
  • Fourteen enhancement procedures were performed for astigmatism and undercorrection.

Main Results:

  • Successful correction of mild hyperopia (≤3.50 D) and presbyopia.

  • Average preoperative hyperopia of +2.22 D corrected to +0.11 D; near vision correction achieved J1 reading.
  • No significant loss of visual acuity or sight-threatening complications were reported.

    • Conclusions:

    • Hexagonal keratotomy can correct mild hyperopia, but results can be variable.
    • Conservative surgical approach with potential for reoperation is suggested.
    • The procedure is no longer performed or recommended due to variable results and reported complications.
