A Study of Artificial Intelligence Assisted Small Incision Lenticule Extraction (SMILE) for Surgical Design and Influencing Factors

Artificial Intelligence Assisted Small Incision Lenticule Extraction (SMILE) for Surgical Design and Nomogram Predicting and Related Influencing Factors to Surgical Outcomes

The goal of this observational study is to learn about the difference of refractive outcomes between Artificial Intelligence and experienced surgeon predicting Nomogram assist SMILE surgical design and the influenced factors of refractive outcomes in patients who underwent Small Incision Lenticule Extraction(SMILE) at the Refractive Surgery Center of Tianjin Eye Hospital. The main questions it aims to answer are:

• Compare the difference of refractive outcomes between Artificial Intelligence and experienced surgeon predicting Nomogram assist SMILE surgical design
• Analysis the influenced factors of refractive outcomes

In this ambispective observation study, to compare the difference of refractive outcomes between Artificial Intelligence and experienced surgeon predicting Nomogram assist SMILE surgical design and Analysis the influenced factors of refractive outcomes, patients have been continuously recruited and the data can then be used for further case-control and cohort studies.

Inclusion Criteria:

• Age of 18 years and older
