Summary
Surgical techniques can reduce visual axis opacification in children with bilateral congenital cataracts. Further research is needed on optimal timing, lens implantation, and long-term complications.
Area of Science:
- Ophthalmology
- Pediatric Surgery
- Clinical Trials
Background:
- Congenital cataracts are a leading treatable cause of childhood vision loss, presenting unique surgical challenges.
- Key complications include intense inflammation, amblyopia, and posterior capsule opacification, impacting treatment outcomes.
- Lensectomy and lens aspiration are common surgical considerations for pediatric cataracts.
Purpose of the Study:
- To evaluate surgical treatments for bilateral symmetrical congenital cataracts.
- To assess treatment success based on visual outcomes and adverse event occurrence.
Main Methods:
- Systematic review of prospective, randomized controlled trials (RCTs) in children aged 15 or younger.
- Searched multiple databases (CENTRAL, MEDLINE, EMBASE, LILACS) and contacted experts.
- Included trials comparing different cataract surgeries or surgery versus no surgery.
Main Results:
- Four RCTs met inclusion criteria, focusing on preventing visual axis opacification (VAO).
- Techniques like anterior vitrectomy or optic capture effectively reduced VAO.
- Posterior capsulotomy alone was insufficient, except in older children.
Conclusions:
- Evidence supports interventions to reduce VAO in bilateral congenital cataracts.
- Further RCTs are necessary to guide practice on surgical timing, intraocular lens implantation, and managing long-term complications like glaucoma and retinal detachment.
