Summary
The Amadeus microkeratome is safe and effective for laser in situ keratomileusis (LASIK) procedures. Corneal thickness and blade reuse influence flap thickness, indicating a learning curve for optimal results.
Area of Science:
- Ophthalmology
- Surgical Technology
- Corneal Surgery
Background:
- Assessing the safety and efficacy of the Amadeus microkeratome.
- Identifying factors for optimizing surgical outcomes.
- Evaluating microkeratome performance in refractive surgery.
Purpose of the Study:
- To evaluate the safety and efficacy of the Amadeus microkeratome.
- To report on lessons learned for optimizing surgical results.
- To analyze flap-related complications in LASIK procedures.
Main Methods:
- Retrospective review of 2000 LASIK procedures using the Amadeus microkeratome.
- Analysis of flap-related complications.
- Preoperative and intraoperative pachymetry in 100 cases to assess flap thickness determinants.
Main Results:
- Low rates of epithelial defects (1.8% minor, 0.2% major).
- No suction loss, buttonholes, or incomplete/damaged flaps.
- Thinner flaps correlated with thinner corneas (P < 0.0001) and blade reuse (P = 0.0001).
Conclusions:
- The Amadeus microkeratome is a safe and reliable instrument for LASIK.
- A learning curve exists for optimizing its use.
- Corneal thickness and blade reuse significantly impact flap thickness.
