1：Experimental Design and Method Selection:

The study involved performing anterior and posterior capsulotomies using a femtosecond laser in pediatric patients with PHPV syndrome. The surgical technique included setting specific laser parameters for capsulotomy diameter, laser power, resection height, and velocity.

2：Sample Selection and Data Sources:

Twelve pediatric patients (12 eyes) with congenital cataracts and PHPV syndrome were included. Preoperative examinations included biomicroscopy, ophthalmoscopy, keratometry, intraocular pressure measurement, A and B ultrasound scanning, ultrasound biomicroscopy, and electroretinography (ERG).

3：List of Experimental Equipment and Materials:

A mobile femtosecond laser system (FEMTO LDV Z8, Ziemer Ophthalmic Systems) was used for the capsulotomies. Other equipment included a Centurion Vision System (Alcon) for phacoaspiration and an ophthalmic viscosurgical device.

4：Experimental Procedures and Operational Workflow:

The procedure involved vacuum-docking the patient interface to the eye, setting laser parameters, performing the capsulotomies, and completing the surgery with phacoaspiration and intraocular lens (IOL) implantation.

5：Data Analysis Methods:

Statistical analyses were performed using SPSS software. The normality of data was assessed using the Shapiro-Wilks test, and differences were analyzed using paired-samples t test or Mann-Whitney U test.
