CIPTA™

Corneal Interactive Programmed Topographic Ablation CIPTA is a synthesis of high definition shape, detailed refractive and dynamic pupil data.

Built of a strong basis of physiological optics while respecting corneal physiology, CIPTA has demonstrated excellent clinical results in delivering custom refractive surgery to primary through complex secondary cases. CIPTA is a fundamental departure from refractive-only approaches marketed with wavefront treatments. Rather than using only refractive data available only through the pupil, CIPTA incorporates a synthesis of refractive, high definition elevation, and pupillometry data. Importantly, surgery is executed on the surface that is mapped in high definition to a 3 micron accuracy. This sharply contrasts to etching a lens / aberration map on a surface thusly altering shape, but without regard or knowledge of its shape. Strong science, excellent results.

 

The Technology
CIPTA’s unique patented process incorporates the following core concepts:
  • The CIPTA's ablation volume is defined by the intersection of Ideal Shape and anterior corneal surface.
    volume
    of the
    ablation
    is defined
    by the intersection of the existing, detected anterior surface of the cornea and the ideal corneal surface. The ablation takes into account the patient’s real anterior corneal surface and it is not derived from a mathematical calculation based upon a lens application.
  • The intersection of the measured surface and the ideal aconic surface must be as large as the ideal pupil seen projected at the anterior surface of the cornea. The optimum ablation dimension minimizes the volume of tissue to be ablated, while assuring that this refractive area completely covers the Ideal Pupil™.

  • The center of the ablation is determined automatically, with the surgeon defining the reference axis of the ideal aconic surface, which by default is the Morphological axis. This can have significant impact on tissue sparing and is a CIPTA exclusive feature.

  • cTEN™ the new custom transepithelial "all laser, no touch" treatment strategy may be performed to eliminate additional keratome induced aberrations that are unmeasured and unaccounted for with LASIK..

  • The variable width transition zone guarantees a constant slope in all radial directions. This constant slope physiologically significantly moderates the risk of regression.

Importantly, CIPTA does not apply a lens without regard to the underlying structure.

 

 

 

 

CIPTA's ablation diameter is delimited by the Ideal Pupil dimension derived from dynamic pupilometry.

CIPTA utilizes a constant slope transition zone / variable width transition zone. This may only be accomplished with detailed knowledge of the shape of the cornea to be reshaped by CIPTA.
