Summary
The IntraLase FS laser created laser in situ keratomileusis (LASIK) flaps with reduced thickness variation and fewer complications than mechanical methods. This laser technology allows for safer correction of myopia.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Laser Technology
Background:
- Laser in situ keratomileusis (LASIK) is a common refractive surgery.
- Traditional LASIK flap creation uses mechanical microkeratomes.
- Improving flap accuracy and reducing complications are key goals in LASIK.
Purpose of the Study:
- To measure the dimensions of LASIK flaps created using the IntraLase FS (IL) laser.
- To compare IL laser flap characteristics with published data from mechanical microkeratomes.
Main Methods:
- Consecutive LASIK flaps were created with the IL laser.
- Flap dimensions were measured using subtraction ultrasound.
- Data were analyzed using statistical software.
Main Results:
- The IL laser produced flaps with a smaller standard deviation in thickness compared to mechanical methods.
- Achieved flap thickness varied, but was consistent.
- Complications like diffuse lamellar keratitis and slipped flaps were eliminated with experience.
Conclusions:
- The IL laser offers improved flap thickness consistency and range compared to mechanical microkeratomes.
- It eliminates physical complications associated with mechanical flap creation.
- This technology enables safer correction of myopia by reducing risks associated with deep ablations.
