Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

No interventions assigned to this group

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.

Intervention Type PROCEDURE

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.
