Artificial Intelligence Assisted Small Incision Lenticule Extraction (SMILE) for Surgical Design and Nomogram Predicting and Related Influencing Factors to Surgical Outcomes
Status: Recruiting
Location: See location...
Intervention Type: Procedure
Study Type: Observational
SUMMARY
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

Treatments
Experienced-nomogram Group
Patients who underwent Small incision lenticule extraction (SMILE) from March 2014 to October 2018 in Refractive Surgery Center of Tianjin Eye Hospital and had at least three months of postoperative follow-up were included in this group. The Nomogram were based on experience of the surgeon.
AI-nomogram Group 1
Patients who underwent Small incision lenticule extraction (SMILE) from November 2018 to May 2021 in Refractive Surgery Center of Tianjin Eye Hospital and had at least three months of postoperative follow-up were included in this group. AI-predicted nomogram was obtained and used on patients who underwent surgery.
AI-nomogram Group 2
Patients who underwent Small incision lenticule extraction (SMILE) from January 2023 in Refractive Surgery Center of Tianjin Eye Hospital and had at least three months of postoperative follow-up were included in this group. The datasets used to train AI(Artificial Intelligence) models have been continuously updated for better accuracy since 2018, the newest AI-predicted nomogram was obtained and used on patients who underwent surgery.
