Reported Advantages of SBK Compared to conventional LASIK

• Less weakening of corneal biomechanics, less risk of ectasia, better stability.
• Faster visual recovery.
• Better quality of vision: fewer higher order aberrations, better contrast sensitivity.
• Fewer complications, less glare, fewer halos.
• Less incidence of postoperative dry eye.
• Reduced loss of corneal sensitivity.
• Greater flap thickness predicatibility.
• Ability to treat more patients, and higher levels of myopia.
• Can treat thinner corneas.
• Reduced enhancement rate.

Planar, Predictable Flaps and Stromal Beds of Unrivaled Smoothness

• Thin flaps with planar architecture.
• Beveled edges.
• Customized diameters.
• Unrivalled bed smoothness.
• Accuracy and predictability equivalent to Femto SBK.

Outcomes of wavefront-optimized Sub-Bowman Keratomileusis (SBK) Malhotra et al. (Chandigarh, India)

In their article 1, Malhotra et al. (Chandigarh, India) performed a prospective comparative clinical study in order to compare the outcomes of wavefront-optimized Sub-Bowman Keratomileusis (SBK) performed using:

 

· One Use-Plus SBK (OUP)(Moria SA, Antony, France) automated microkeratome in 25 myopic patients with astigmatism up to a maximum of 2 D;

 

· and the latest generation 150 kHz IntraLase® (iFS) femtosecond laser (Abbott Medical Optics, Santa Ana, CA, USA) in another group of 25 myopic patients with astigmatism up to a maximum of 2 D;

 

All treatment parameters were the same, and all suitable patients were followed up at 1 day, 1 week, 1 month and 3 months after surgery. Postoperative refraction and wavefront measurements were conducted by optometrists who were blinded to the method of flap creation.

 

Authors found that:

 

· efficacy, refractive stability, predictability, and safety profiles were comparable between the two groups;

 

· visual acuity outcomes were similar irrespective of whether flaps were made by a femtosecond laser or by the Moria automated microkeratome;

· although higher order aberrations (HOAs) increased significantly in both groups after SBK, the iFS group was associated with a significantly higher induction of both total HOAs and spherical aberrations compared to the OUP group;

 

Based on their prospective clinical study, Malhotra et al. therefore concluded:

 

“flaps created using the Moria One Use-Plus SBK microkeratome were associated with significantly lower induction of total HOAs and spherical aberrations as compared with 150 kHz iFS flaps at the end of 3 months follow-up

Keep your LASIK in mechanical microkeratome
James Lewis, MD (Elkins Parks, PA - USA)

"Click-Free LASIK": have you already heard of a SBK procedure without any click-fees? compared to elevated cost associated of the routinely use of a femtosecond laser. In addition of that cost point of view, Dr. Lewis highlighted the efficacy of the Moria One Use-Plus SBK microkeratome to create 100-micron flaps with a high degree of accuracy, predictability and reproducibility. AS-OCT pictures show the perfect architecture of mechanically created sub-Bowman's flaps. Get the whole story here...
