Purpose:
To evaluate the incidence of intraoperative complications using the NIDEK MK-2000 microkeratome during flap creation in LASIK.
Methods:
The incidence of intraoperative flap complications during LASIK using the NIDEK MK-2000 microkeratome was retrospectively studied in 26,600 procedures performed in 5 outpatient excimer laser surgery centers.
Results:
A total of 65 (0.244%) complications were identified: 23 (0.086%) eyes had free caps, 13 (0.049%) eyes had an incomplete pass, 13 (0.049%) eyes had an epithelial defect, 11 (0.041%) eyes had buttonhole, and 5 (0.019%) eyes had irregular flap. The remaining 26,535 (99.756%) eyes had uneventful flap creation.
Conclusions:
Use of the NIDEK MK-2000 microkeratome resulted in a low incidence of intraoperative complications, making it a safe and reliable device for creating flaps during LASIK.
Insights
The NIDEK MK-2000 microkeratome demonstrated a low incidence of intraoperative complications during LASIK flap creation. This study confirms its safety and reliability for refractive surgery procedures.
Area of Science:
- Ophthalmology
- Surgical Technology
- Refractive Surgery
Background:
- Laser-Assisted In Situ Keratomileusis (LASIK) is a common refractive surgery.
- Microkeratomes are essential for creating corneal flaps during LASIK.
- Evaluating device-specific complication rates is crucial for surgical safety.
Purpose of the Study:
- To assess the rate of intraoperative complications associated with the NIDEK MK-2000 microkeratome.
- To determine the safety and reliability of this specific microkeratome in LASIK procedures.
Main Methods:
- Retrospective analysis of 26,600 LASIK procedures.
- Data collected from 5 outpatient excimer laser surgery centers.
- Focus on intraoperative flap complications using the NIDEK MK-2000.
Main Results:
- A total of 65 (0.244%) intraoperative complications were recorded.
- Specific complications included free caps (0.086%), incomplete passes (0.049%), epithelial defects (0.049%), buttonholes (0.041%), and irregular flaps (0.019%).
- The vast majority of procedures (99.756%) had uneventful flap creation.
Conclusions:
- The NIDEK MK-2000 microkeratome exhibits a low incidence of intraoperative complications.
- The device is deemed safe and reliable for LASIK flap creation.
- Findings support the continued use of the NIDEK MK-2000 in refractive surgery.
