Laser-Assisted In Situ Keratomileusis (LASIK) using a thinner 130-microm microkeratome head is as effective and safe as using a thicker 160-microm head. This thin-flap LASIK procedure demonstrates comparable visual outcomes and minimal complications.

Area of Science:

  • Ophthalmology
  • Refractive Surgery

Background:

  • Laser-Assisted In Situ Keratomileusis (LASIK) is a common refractive surgery procedure.
  • Microkeratome head thickness is a critical parameter influencing flap creation and surgical outcomes.

Purpose of the Study:

  • To compare the visual effectiveness and safety of LASIK utilizing a 130-microm microkeratome head (thin-flap LASIK) versus a 160-microm head.

Main Methods:

  • A comparative study evaluated postoperative day 1 uncorrected visual acuity (UCVA) and flap complications.
  • Eyes undergoing myopic LASIK with either a 130-microm or 160-microm head using the BD K-3000 microkeratome were analyzed.

Main Results:

  • The mean preoperative myopia was -5.00 D for the 130-microm group and -3.78 D for the 160-microm group.

  • Postoperative day 1 UCVA was 20/25 for the 130-microm head group and 20/26 for the 160-microm head group.
  • Only one partial flap complication occurred, in the 160-microm head group.

    • Conclusions:

    • LASIK with a 130-microm head (thin-flap LASIK) is as visually effective as using a 160-microm head.
    • Thin-flap LASIK with the BD K-3000 microkeratome demonstrates comparable safety to the standard 160-microm head.
