Summary
This study presents a new positioning dot method for accurately repositioning laser in situ keratomileusis (LASIK) corneal flaps created without alignment marks. This technique ensures proper flap orientation on the stromal bed, crucial for successful refractive surgery outcomes.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Corneal Surgery
Background:
- Repositioning free laser in situ keratomileusis (LASIK) corneal flaps without fiduciary marks presents a surgical challenge.
- Accurate flap alignment is critical for optimal visual outcomes after LASIK surgery.
Purpose of the Study:
- To describe a novel protocol for the adequate repositioning of free LASIK corneal flaps.
- To evaluate the efficacy of a positioning dot method for flap alignment using the Moria M2 microkeratome.
Main Methods:
- A protocol was developed involving the placement of a positioning dot on the free flap before its retrieval from the microkeratome.
- Surgical landmarks were utilized to guide the correct alignment of the flap to the stromal bed.
- The technique was tested on enucleated porcine eyes using a Moria M2 microkeratome.
Main Results:
- The positioning dot method successfully achieved adequate orientation of the free LASIK corneal flap to the stromal bed in 9 porcine eyes.
- The protocol demonstrated effectiveness in repositioning flaps created without the need for pre-existing fiduciary marks.
Conclusions:
- A positioning dot method provides an effective means for repositioning free LASIK corneal flaps created by the Moria M2 microkeratome.
- This technique is specific to the Moria M2 microkeratome and requires validation for other microkeratome systems.
