CIPTA® – Corneal Interactive Programmed Topographic Ablation
Applying more than 2 decades of Experience in Customized Corneal Surgery.
CIPTA® advanced planning software was born in 1996 to plan fully customized refractive and therapeutic treatments, by means of the definition of the Ideal Shape, thus optimizing the patient’s quality of vision and minimizing the surgical invasiveness.
CIPTA® is the ultimate tool for the Ophthalmic Surgeons, dedicated to plan the customized treatment by combining Precisio® morphological and refractive data with the Ideal Pupil computed by pMetrics® and the refractive error to be corrected.
CIPTA® is granting, as the natural consequence of the corneal regularization, by means of the Ideal Shape, a great vision for each patient.
CIPTA® planning incorporates a variable-width transition zone, in order to maintain a constant slope with linear variation of the corneal curvature and thus minimizes the risks of regression and of post-op halos and starbursts.
CIPTA® supports and delivers customized treatment plans for :
- Therapeutic ectatic cases by means of a combined technique which provides corneal regularization and cross linking.
- Therapeutic stable cases such as irregular astigmatism, decentrations, central islands and refractive errors induced by previous refractive surgery.
- Primary refractive disorders.
CIPTA® features our unique cTen® (Custom Trans Epithelial No-touch) one-step approach as well as all common refractive strategies such as Lasik, Lasek, PRK.
CIPTA® proprietary surgical process incorporates the following core concepts:
– The ablation volume is defined by the intersection of the Ideal Shape that is the regular aberration free surface designed on patient’s refractive needs, and the real corneal surface as acquired by Precisio® tomographer.
– The refractive zone is limited by the diameter equal to the sum of the projected ideal pupil, as identified by pMetrics® pupillometer, onto the ideal corneal shape added of the distance included between the centre of the treatment and the pupil centroid.
– The connecting zone between the refractive zone and the remaining untouched surface of the cornea is designed to grant a constant slope in each radial direction.
The default planning strategy is automatically presented. The Surgeon may customize each single parameter.

Discover the CIPTA® advantages
CIPTA® is the synthesis of high-definition corneal morphology and refractive data, dynamic pupil assessment and aimed refractive error.
CIPTA® demonstrated excellent clinical results in delivering custom refractive surgery to primary refractive cases through complex therapeutic cases.
CIPTA® is a fundamental departure from refractive-only approaches marketed with Wavefront measurements. Rather than using only refractive data available through the pupil, CIPTA® incorporates a synthesis of Precisio® morphological and refractive data with the Ideal Pupil computed by pMetrics® and the refractive error.
Importantly, surgery is executed on the surface that is detected in high-resolution by Precisio®. This sharply contrasts with the widespread approach to etching a lens, thus producing an aberration map on an unknown surface.
CIPTA® vs. Wavefront Ablations
iVis believes a Wavefront approach is technically limited.
The philosophy that drives CIPTA® states that the refractive outcome is the natural consequence of the modifications of the corneal morphology.
Customised ablations based only on aberrometric data deduced by Wavefront devices and/or topographers attempt to directly compensate for the refractive error under the assumption that there is no need to know the corneal morphology.
Wavefront ablation profiles are based on a lens to be applied onto the cornea with no consideration of the corneal morphology.
CIPTA®, in order to optimize the quality of vision, regularizes the anterior surface of the cornea by defining the ideal surface, thus removing only the limited portion of stromal tissue included between the anterior corneal profile and the ideal surface.
CIPTA®, thanks to the principle of the intersection between the anterior corneal profile and the ideal surface, proportionally requires less tissue ablation as the irregularities of the cornea increase, as opposed to Wavefront-guided ablations which require a higher amount of tissue as irregularities increase.
Discover iVis exclusive No-Touch procedure for custom refractive and therapeutic corneal surgery.
cTen® is a Trans-epithelial treatment which implies that the laser will remove, in one single step, only the necessary fraction of epithelium and stroma, according to the planned ablation profile to optimise the quality of vision. This smooth process allows for the execution of a fully No-Touch laser procedure, free from intraoperative risk of complications which does not require any eye manipulation.
cTen® dramatically reduces patients’ and surgeons’ time in the operating theatre being a Fast one-step surgery.
cTen® thanks to its gentle laser ablation limited to the treatment zone, dramatically accelerates corneal healing.
Discover Asphericity Interactive – “AI”
The AI function interactively compensates for multiple, interdependent factors affecting asphericity.
CIPTA® includes our exclusive algorithm AI. Only AI fully and interactively compensates for multiple factors each affecting and affected by asphericity.
AI is an easy to use, Surgeon-friendly surgical design tool that eliminates the need for very complex, multi-factored compensation calculations with variable interdependencies on:
– Corneal curvature
– Photopic pupil dimensions
– Refractive power change
– Asphericity change
AI is truly customised asphericity.
