Safety and Effectiveness of Thin-flap LASIK Using a Femtosecond Laser and Microkeratome in the Correction of High Myopia in Chinese Patients

Abstract

Thin-flap LASIK with a femtosecond laser and microkeratome are both safe and effective for the correction of high myopia in Chinese patients. Femtosecond laser shows similar predictability, stability, and induction of higher order aberrations to the microkeratome.

Long-term comparison of corneal aberration changes after laser in situ keratomileusis: Mechanical microkeratome versus femtosecond laser flap creation

“…Table 4 shows the main outcomes in these studies. 6,7,9,[14][15][16][17][18][19] The visual and refractive outcomes in the studies, including ours, were similar. The small differences between the studies may arise from those at the time of postsurgery examinations, the degree of myopia corrected, or which excimer laser or mechanical microkeratome was used.…”

“…Although studies have analyzed changes in the short and medium term after LASIK (3 to 36 months), 6,7,9,[14][15][16][17][18][19] to our knowledge, there are no long-term studies of the differences between LASIK flap creation with a femtosecond laser and LASIK flap creation with a microkeratome. The purpose of this randomized study was to assess the differences in visual and optical performance 4 years after LASIK in which the flap was created with 1 of these methods.…”

“…6,7,9,[14][15][16][17][18][19] Comparative studies of visual acuity between the 2 methods of flap creation found no differences for 1 year 16,17 to 3 years 19 after surgery. Table 4 shows the main outcomes in these studies.…”

Effect of scanning patterns on the results of femtosecond laser lenticule extraction refractive surgery

“…These parameters are used for patient selection in regular practice at the study clinic and are similar to parameters used in other recent studies. 10,11 These parameters are also based on the risk factors for keratectasia. 12 Some eyes were not fully corrected to allow monovision treatment, to delay the onset of near vision correction, or because the software did not allow treatment of spherical equivalent more than À10.00 D.…”

Long-term comparison of laser in situ keratomileusis versus laser surface ablation in corneas thinner than 470 μm

“…26 Li et al 27 found that thin-flap LASIK with femtosecond laser and microkeratome was safe and effective for the correction of high myopia in Chinese patients. The safety of the techniques for creating very thin flaps described here should be verified in studies with larger samples.…”
