Key Takeaway

Consider capsular bag fixation as the preferred approach due to higher risk of secondary glaucoma in ciliary sulcus.

This meta-analysis evaluates the safety and efficacy of ciliary sulcus fixation compared to capsular bag fixation in children with cataracts. The analysis included a total sample size of 843 patients to assess primary outcomes and several secondary outcomes including postoperative BCVA, spherical equivalent, and inflammation incidence.

The synthesis indicates no significant differences between the two techniques regarding postoperative BCVA, spherical equivalent, visual axis opacity, or inflammation incidence (p > 0.05). However, ciliary sulcus fixation was associated with a significantly higher risk of secondary glaucoma (RR = 0.43; 95%CI 0.20-0.96, p = 0.04). Additionally, myopic shift and uveitis incidence were reported as higher in the ciliary sulcus group.

The authors note that the finding of a higher risk of secondary glaucoma was not robust in sensitivity analysis. Despite this limitation, the study suggests that capsular bag fixation is the preferred approach for these patients. Clinical application should consider these findings while acknowledging the lack of robustness in the specific glaucoma risk finding.

How this fits prior evidence

This meta-analysis addresses a gap in surgical technique selection for pediatric cataract cases. While previous evidence has explored surgical interventions to improve refractive error in short eyes and combined phacoemulsification with angle filtering to reduce intraocular pressure in glaucoma patients, this study specifically compares fixation methods. It confirms the preference for capsular bag fixation over ciliary sulcus fixation, which showed a significantly higher risk of secondary glaucoma (RR = 0.43).

This review looked at the safety and effectiveness of two different surgical techniques for treating cataracts in children. Researchers compared capsular bag fixation with ciliary sulcus fixation to see which method provided better outcomes for young patients.

While both methods showed similar results for vision clarity, inflammation, and eye shape, one method showed specific risks. The study found that ciliary sulcus fixation was linked to a higher risk of secondary glaucoma. Additionally, patients who underwent ciliary sulcus fixation showed more frequent cases of uveitis and a more pronounced myopic shift in certain cases.

Because of these risks, capsular bag fixation is currently recommended as the preferred approach for children. However, it is important to note that the finding regarding glaucoma risk was not robust in some sensitivity analyses. Patients and families should discuss these specific surgical risks with their eye specialist to choose the safest path for a child's eye health.

What this means for you:

Capsular bag fixation is the preferred method for pediatric cataracts due to lower risks of glaucoma and uveitis.

Common questions

Is one surgery safer for children with cataracts?

Capsular bag fixation is recommended as the preferred approach. While both methods showed similar results for vision and inflammation, ciliary sulcus fixation was linked to a higher risk of secondary glaucoma and more frequent uveitis in children.

What are the risks of ciliary sulcus fixation?

Ciliary sulcus fixation showed a significantly higher risk of secondary glaucoma (RR = 0.43). It was also associated with a higher incidence of uveitis and a more pronounced myopic shift in cases of acquired cataracts.

How do the two methods compare for vision results?

The study found no significant differences between the two methods regarding postoperative best-corrected visual acuity (BCVA), spherical equivalent, or visual axis opacity. Both methods performed similarly in these specific areas.

PURPOSE: To systematically compare the safety and efficacy of ciliary sulcus versus capsular bag fixation in pediatric intraocular lens implantation. METHODS: We searched observational studies and RCTs in databases from inception until March 2025. Statistical analysis was performed using RevMan 5.4. RESULTS: Eight studies (843 patients) were included. No significant differences were found in postoperative BCVA, spherical equivalent, visual axis opacity, or inflammation incidence (p > 0.05). Ciliary sulcus fixation showed a significantly higher risk of secondary glaucoma (RR = 0.43, 95%CI 0.20-0.96, p = 0.04). However, this finding was not robust in sensitivity analysis. In acquired cataract cases, myopic shift was more pronounced in the ciliary sulcus fixation group; worse visual outcomes were observed in the capsular bag fixation group among patients without amblyopia therapy. Uveitis incidence was higher in the ciliary sulcus group. CONCLUSION: While both techniques show comparable efficacy, ciliary sulcus fixation significantly increases risks of secondary glaucoma and uveitis, and is associated with myopia progression. Capsular bag fixation is recommended as the preferred approach, with enhanced postoperative amblyopia treatment and long-term monitoring.
