Summary
The Nidek MK-2000 microkeratome is safe for laser in situ keratomileusis (LASIK) procedures. It consistently creates corneal flaps of predictable thickness, minimizing complications during surgery.
Area of Science:
- Ophthalmology
- Surgical Technology
- Corneal Surgery
Background:
- Laser in situ keratomileusis (LASIK) is a common refractive surgery.
- Accurate corneal flap creation is crucial for LASIK outcomes.
- Microkeratome performance directly impacts flap characteristics.
Purpose of the Study:
- To evaluate the flap thickness accuracy of the Nidek MK-2000 microkeratome.
- To assess the safety and performance of the Nidek MK-2000 during LASIK.
- To analyze flap characteristics using different depth plates and model numbers.
Main Methods:
- Subtractive pachymetry was used to measure flap depth in 370 eyes.
- The Nidek MK-2000 microkeratome, with 130-µm and 160-µm depth plates, was utilized.
- Microkeratome-induced complications were systematically recorded.
Main Results:
- No buttonhole or free flaps were observed.
- One short flap and two instances of suction loss occurred.
- Mean flap thicknesses ranged from 129 ± 21.8 µm to 173 ± 26.9 µm, depending on the model and depth plate.
Conclusions:
- The Nidek MK-2000 microkeratome demonstrates a high safety profile.
- The device produces corneal flaps with predictable and reliable thickness.
- This microkeratome is suitable for LASIK procedures requiring precise flap creation.
