Visumax femtolasik versus Moria M2 microkeratome in mild to moderate myopia: efficacy, safety, predictability, aberrometric changes and flap thickness predictability

“…After 3 months, all eyes had CDVA of 20/25 and UDVA of 20/40, 91% of eyes reached UDVA of 20/20 or better, 94% of eyes were within ±0.50 D of the planned correction. Similar results reported by Issa A et al [19]Due to variable results obtained by comparison of different MKs and different femtolaser systems, in a recent study in 2012, Chen S et al [14] conducted a comprehensive literature search to identify relevant trials comparing IntraLase FSL to LASIK with MKs for the correction of myopia. They found 15 articles describing a total of 3679 eyes.…”

Transitioning from mechanical microkeratome to femtosecond laser flap creation: Visual outcomes of an experienced and a novice LASIK surgeon

“…All treatments were performed as bilateral simultaneous LASIK using the Visumax femtosecond laser [15][16][17][18] and the MEL 80 excimer laser. 13 A nomogram based on previous treatments was used to calculate the laser data entry; both surgeons used the same nomogram.…”

Optimal parameters to improve the interface quality of the flap bed in femtosecond laser-assisted laser in situ keratomileusis

“…[4][5][6] Various clinical studies have reported a smaller variation in the targeted flap thickness with the femtosecond laser than with the microkeratome 7,8 as well as a more regular flap thickness profile. 9 However, irregularities of the stromal interface, even after femtosecond laser flap creation, have also been described. 10 The femtosecond laser can create, with high accuracy, flaps thinner than those created by the microkeratome, allowing the surgeon to treat eyes whose corneal thickness might be a contraindication to LASIK surgery.…”

“…10 The femtosecond laser can create, with high accuracy, flaps thinner than those created by the microkeratome, allowing the surgeon to treat eyes whose corneal thickness might be a contraindication to LASIK surgery. 8,9 Controversies remain concerning the advantages of the femtosecond laser over the microkeratome in improving clinical outcomes, such as postoperative visual performance and corneal higher-order aberrations (HOAs). Calvo et al 11 report that the planar configuration of the femtosecond laser flap does not offer any advantage in corneal HOAs or visual acuity over a 3-year follow-up, whereas Lim et al 5 report a smaller degree of postoperative spherical aberration in patients who had femtosecond LASIK than in those who had LASIK with a mechanical microkeratome.…”
