A Prospective Randomized Clinical Trial of Laser In Situ Keratomileusis With Two Different Lasers

Retrospective comparison of 3 laser platforms to correct myopic spheres and spherocylinders using conventional and wavefront-guided treatments

“…22,23 This study is unique in that a femtosecond laser was used to create all flaps, eliminating the use of different microkeratomes as a source of potential HOA variability. Recent data 24 suggest that for flap creation, the femtosecond laser creates fewer HOAs than the mechanical microkeratomes used in these previous studies.…”

Sensitivity of the National Eye Institute Refractive Error Quality of Life instrument to refractive surgery outcomes

“…Patients were required to be at least 21 years of age and have myopic refractive error between ÿ1.00 and ÿ7.00 diopters (D), with less than ÿ3.00 D of astigmatism (measured via cycloplegic subjective refraction). 7 Patients were excluded from participating in this trial if (1) they had a difference in high-contrast visual acuity of 4 or more letters between eyes, (2) visual acuity worse than 20/32 in either eye, (3) spherical anisometropia more than 1.00 D, (4) cylindrical anisometropia more than 0.75 D, (5) an intended ablation that would leave an estimated corneal thickness less than 250 mm, (6) anterior segment pathology or previous ocular surgery, or (7) a history of systemic autoimmune disease or immunosuppressive therapy, or were pregnant or lactating. Hydrogel lens wearers were required to discontinue lens wear 2 weeks before surgery, and rigid gas-permeable lens wearers were required to discontinue wear 3 weeks before surgery.…”

Prospective randomized trial of wavefront-guided laser in situ keratomileusis with the CustomCornea and CustomVue laser systems

“…[1][2][3][4] Wavefront-guided systems increase the predictability of visual outcomes and may reduce the amount of induced aberrations compared with conventional LASIK surgery. [4][5][6][7][8][9][10][11] One important question is whether there are differences in visual outcomes between the available wavefront-guided systems.…”
