Hexagonal keratotomy--should we still be trying?
1Department of Ophthalmology, University of Virginia, Charlottesville 22904, USA.
Summary
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.
