Brief Summary

Lens capsular often changes after pediatric cataract surgery,causing complications such as anterior capsulerhexis shrinkage, visual axis opacification (VAO), zonular dehiscence and so on. The aim of study was to prospectively investigate the capsular outcomes of pediatric cataract surgery with primary intraocular lens (IOL) implantation.

Outcome Measures

Primary Outcomes (2)

  • PCOA

    A comparison of posterior capsular opening areas at the corresponding time points

    20.74 ± 7.89 months

  • VATA

    A comparison of visual axis transparent areas at the corresponding time points

    20.74 ± 7.89 months

Secondary Outcomes (1)

  • axial length growth

    20.74 ± 7.89 months

Study Arms (1)

pediatric cataract group

Children who underwent cataract surgery and primary IOL implantation at the Eye Hospital of Wenzhou Medical University (Hangzhou, China) between 2016 and 2019 were included in the study. Every surgery included posterior capsulorhexis or capsulotomy and anterior vitrectomy. Patients accept slit-lamp-adapted anterior segmental photography at 1 week, 2 weeks, 1 month, 3 months, and 6 months postoperatively.

Study Population

Patients (age:0.5\~8.0 years)with congenital cataract

You may qualify if:

  • Children (age 0.5\~8 years) who underwent cataract surgery, posterior capsulorhexis or capsulotomy and anterior vitrectomyand primary IOL implantation at the Eye Hospital of Wenzhou Medical University (Hangzhou, China). The follow-up period was at least 1 year.

You may not qualify if:

  • Patients with ocular trauma, corneal disorders, glaucoma, preoperative lens luxation or subluxation, membranous cataract, persistent hyperplastic primary vitreous, surgical or postoperative complications such as glaucoma or suspect-glaucoma and synechia, pupils that could not be sufficiently dilated, and those who could not complete follow-ups or did not have clear digital photographs.
