The 3C Calculator is meant to serve as an adjunct tool (IOL calculator, SIA calculator, Constant calculator, SIRC Calculator) to assist physicians in selecting the appropriate IOL for a particular patient (virgin eyes and after refractive surgery).

It is intended to be used in conjunction with a comprehensive ophthalmic examination (biometry) and the appropriate diagnostic tests and measurements necessary for cataract surgery candidates with/without a history of prior refractive surgery (IOL calculator after refractive surgery).

The results obtained by the IOL calculator are not intended to serve as medical or surgical instruction, or be definitive; nor can SEKAL Micro Chirurgia Rovigo guarantee that the results will be accurate in every case.

Physicians who use the IOL calculator must arrive at their own independent determinations regarding the proper treatment for their patients and are solely responsible for the refractive outcome.

By using the 3C Calculator, you agree to waive and hold SEKAL Micro Chirurgia Rovigo and authors harmless from any claims you may have arising out of your use of this tool.

You can request access to 3C Calculator by Terms and Conditions which implies full approval of the terms and conditions that SEKAL Micro Chirurgia Rovigo imposes on those who will use it.
