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.
