There is not good analysis without reliable data and for this purpose Protocols are the Key point. A Protocol is an uniform way to act in all the cases to minimize the bias in the results. In order to design a good Protocol for organizing your data ask you the following questions:

1. What is the eye operated on?
2. Which procedure I have followed for the incision, femtosecond or keratome?
3. Has been the IOL inserted preloaded?
4. Where is the incision located?
5. Which system / parameter I have used for measuring the corneal power?

When all the questions match for a serie of patients you have followed a Protocol, but If one answer is different between patients, you are adding noise into your data. Remember, it is the similar a small sample and reliable data than BigData with poorer reliability, if you start to do the data collection in a right way you will achieve your purpose earlier.

Here you have a sample for a protocol:

1. What is the eye operated on? Right eye
2. Which procedure I have followed for the incision, femtosecond or keratome? Femtosecond
3. Has been the IOL inserted preloaded? Yes
4. Where is the incision located? Temporal (0-180º)
5. Which system/parameter I have used for measuring the corneal power? IOL Master 500 SimK

For this protocol I have selected the Title: RE-Femto-temp-500
