Summary
Arcuate keratotomy using the Terry astigmatome effectively reduced corneal astigmatism, improving uncorrected visual acuity. This procedure proved to be a safe and reliable surgical option for patients with astigmatism.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Surgery
Background:
- Astigmatism is a common refractive error impacting visual quality.
- Surgical correction of astigmatism aims to restore clear vision.
- Arcuate keratotomy is a surgical technique to correct astigmatism.
Purpose of the Study:
- To evaluate the refractive outcomes of arcuate keratotomy for astigmatism.
- To assess the safety and efficacy of the Terry astigmatome in astigmatism correction.
Main Methods:
- The study included 16 eyes from 11 patients with astigmatism.
- Arcuate keratotomy was performed using the Terry astigmatome.
- Preoperative and postoperative assessments included visual acuity, corneal topography, and pachymetry.
Main Results:
- Mean preoperative corneal astigmatism was -4.0 D, reduced to -1.8 D postoperatively.
- Mean uncorrected visual acuity improved significantly from 0.74 to 0.18 logMAR.
- No intraoperative or postoperative complications were reported.
Conclusions:
- Arcuate keratotomy with the Terry astigmatome is a safe and reliable treatment for corneal astigmatism.
- The procedure leads to significant reduction in astigmatism and visual acuity improvement.
