Summary
Lensectomy and lens aspiration for congenital cataracts show similar visual outcomes. However, lensectomy results in significantly less secondary opacification compared to lens aspiration in children.
Area of Science:
- Ophthalmology
- Pediatric Surgery
- Clinical Trials
Background:
- Congenital cataracts affect vision in children, posing unique surgical challenges like inflammation and amblyopia.
- Cataract surgery in children requires careful consideration of treatment methods.
- Lensectomy and lens aspiration are common surgical options for pediatric cataracts.
Purpose of the Study:
- To evaluate surgical treatments for bilateral symmetrical congenital cataracts.
- To compare visual outcomes and adverse events between different surgical approaches.
- To inform best practices for managing pediatric cataracts.
Main Methods:
- Systematic review of prospective, randomized controlled trials in children aged 15 or younger.
- Inclusion of trials comparing cataract surgery types or surgery versus no surgery.
- Data extraction by two reviewers; no meta-analysis performed.
Main Results:
- One trial involving 65 children met the criteria, randomizing 130 eyes.
- No significant difference in visual acuity was found between lensectomy and lens aspiration with primary capsulotomy at three years.
- Secondary opacification occurred in 66% of lens aspiration cases versus 2% in lensectomy cases.
Conclusions:
- Both lensectomy and lens aspiration offer good visual results for bilateral congenital cataracts.
- Lensectomy demonstrates a lower incidence of secondary opacification compared to lens aspiration.
- Further randomized trials are needed to guide optimal surgical strategies for congenital cataracts.
