What this trial studies

This observational study aims to compare the refractive outcomes of Small Incision Lenticule Extraction (SMILE) surgery when assisted by Artificial Intelligence versus predictions made by experienced surgeons. It will analyze various factors that influence these outcomes in patients who have undergone the procedure at the Refractive Surgery Center of Tianjin Eye Hospital. Data collected from participants will also be utilized for future case-control and cohort studies to enhance understanding of surgical design and effectiveness.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 18 and older with stable refraction and good corrected distance visual acuity.

Not a fit: Patients with abnormal corneal features, severe dry eye, or a history of eye surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes for patients undergoing myopia correction.

How similar studies have performed: While the use of AI in surgical design is a growing field, this specific approach comparing AI predictions to experienced surgeons is relatively novel.
