Once you have the subject you can start to insert Exams, a subject can have as many exams as protocols created. A protocol is an uniform way to act for a sample of patients. For instance, you can have a protocol for all the right eyes, another for left eyes, right eyes measured with Ksim, Right eyes measured with total corneal power, right eyes with incision at 180º, and right eyes with incision at steep axis,... The most important thing here is that you have to classify each exam in a specific protocol and you don't have to mix data, for instance patients measured with Ksim y TCRP in the same protocol. Furthermore, maintain the same devices for the measurement preoperative and postoperative

BigSIA

The incision that is required for IOL implantation during cataract surgery induces astigmatism —this is referred to as surgically induced astigmatism (SIA)— so the total amount of astigmatism to be corrected with the toric IOL must consider the flattening (FE) or steepening (SE) effect on the meridian of the preoperative corneal astigmatism on which the IOL is going to be aligned. The SIA will depend on several factors, including incision type, location and size, and its design or architecture.
