Intelligent Cataract Screening With Portable Slit-lamp

• Conditions: Catarct Screening; Artificial Intelligence
• Interventions: Device: Portable slit-lamp photography

• Registration Number: NCT05204095
• Lead Sponsor: Sun Yat-sen University

Brief Summary

Based on the portable slit-lamp connected to the smartphone, the artificial intelligence machine learning algorithm is used to establish a cataract screening model by prospectively collecting the anterior segment photographic data, and a portable slit lamp intelligent screening referral model based on the smartphone connection is also established.

Arm && Interventions

Group	Intervention	Description
Referral group	Portable slit-lamp photography	The patients with severe cataracts in this group need a referral to a higher-level hospital for further treatment.
Observation group	Portable slit-lamp photography	The patients with mild cataracts or transparent lenses in this group do not need a referral to a higher-level hospital for further treatment and keep regular examinations.

Primary Outcome Measures

Name	Time	Method
The accuracy of referral	Baseline	The accuracy of referral of AI model will be calculated with the decisions based on the portable slit-lamp images with reference to the ground truth.

Secondary Outcome Measures

Name	Time	Method
The accuracy of cataract diagnosis	Baseline	The accuracy of cataract diagnosis of AI model will be calculated with the decisions based on the portable slit-lamp images with reference to the ground truth.
