Objective:
To assess the long-term stability of astigmatism correction using femtosecond laser-created arcuate incisions.
Key Findings:
- Preoperative astigmatism reduced significantly from 0.62±0.37 D to 0.32±0.27 D at 4 to 6 weeks postoperatively.
- More than 90% of eyes achieved a surgically induced astigmatism within 0.5 D of the target.
- Mean UCVA was maintained from 0.09±0.11 logMAR at 4 to 6 weeks to 0.08±0.09 logMAR at 24-36 months.
- 95.5% of eyes achieved postoperative UCVA of 20/30 or better.
Interpretation:
The study demonstrates the long-term stability and effectiveness of femtosecond laser-created beveled arcuate incisions for managing low-to-moderate astigmatism.
Limitations:
- Small sample size of 20 eyes.
- Lack of control group for comparison.
Conclusion:
Femtosecond laser arcuate incisions provide a precise and durable option for astigmatism correction, especially when toric IOLs are not suitable.
