PURPOSE: The evaluation of the safety, efficacy, and long-term stability of LASIK procedures utilizing novel platform comprising a femtosecond and excimer laser and multiple networked diagnostics.
SETTING: Private clinical ophthalmology practice.
PATIENTS AND METHODS: In consecutive cases of myopic LASIK procedure with a novel refractive platform (FS200 Femtosecond and EX500 Excimer Laser), 190 eyes (from 109 different patients) were evaluated pre- and postoperatively for the following parameters: refractive error, best corrected distance visual acuity, uncorrected distance visual acuity, topography (Placido-disc based) and tomography (Scheimpflug-image based), wavefront analysis, pupillometry, and contrast sensitivity. Follow-up visits were conducted for at least 12 months.
RESULTS: The change from pre- to postoperative mean refractive error was from -5.29 ± 2.39 diopters (D) (range -8.0 to -0.50 D) to -0.27 ± 0.09 D at the 3-month visit, -0.27 ± 0.10 D at the 6-month visit, and -0.39 ± 0.08 D at the 1-year visit. The change from pre- to postoperative refractive astigmatism was -1.07 ± 0.91 D (range -4.25 to 0 D) to -0.14 ± 0.04 D at 3 months, -0.15 ± 0.04 at 6 months, and -0.16 ± 0.04 at the 1-year visit. The proportion of the eyes with postoperative astigmatism within 0.5 D ranged between 95.6% and 99%. The proportion of eyes achieving uncorrected distance visual acuity of 1.0 (decimal) was 93.0%.
CONCLUSION: The myopic LASIK clinical results with the FS200 Femtosecond Laser and EX500 Excimer Laser showed outstanding efficacy, great safety, and long-term stability.
