Refractive Errors, Cycloplegic Refraction
ML Models Predicting Cycloplegic Refractive Error Based on Non-Cycloplegic Parameters in Myopic Adults
This study presents a machine learning model that predicts cycloplegic refraction in adults with myopia using standard non-cycloplegic eye measurements, aiming to reduce the need for cycloplegic drops while still identifying…

Cataract (Post-operative Cataract Surgery Follow-up), Refraction Error
Can Tailored Surgical Incisions Reduce Refractive Error and Dependence on Glasses After Cataract Surgery?
Astigmatism is a common cause of continued dependence on glasses after cataract surgery and may lead to patient dissatisfaction with surgical outcomes.

- Testing
- Adapted clear corneal incisions
- Volunteers
- 100 people
