Consensus has not been established regarding an effective surgical method for preventing secondary visual axis opacification (VAO) in pediatric cataract surgery. This retrospective, observational, clinical study aims to elucidate the efficacy of optic capture (OC) without anterior vitrectomy in pediatric cataract surgery.
We conducted a chart review of 34 eyes of 24 children with congenital or developmental cataract who had undergone cataract surgery with intraocular lens (IOL) implantation. There were 16 boys (21 eyes) and 9 girls (15 eyes) aged 1–14 (mean ± SD: 7.6 ± 3.9) years. Eighteen eyes of 12 children (mean age, 6.5± 3.5) underwent cataract surgery, including anterior capsule curvilinear capsulorhexis (ACCC), lens aspiration, posterior CCC (PCCC), and optic capture without anterior vitrectomy (OC group). While, 16 eyes of 12 children (mean age, 9.2 ± 4.0) underwent cataract surgery similar to those in the OC group, but without OC (No OC group). We compared post-operative VAO and visual acuity.
The mean follow-up was 34.8 ± 27.6 months. We observed a significant VAO in 0 and 5 eyes in the OC and No OC groups, respectively (P = 0.016; Fisher Exact Test). Post-operative mean best-corrected visual acuities (BCVAs) were logMAR 0.025 and 0.004 in the OC and No OC groups, respectively (P = 0.041; Mann–Whitney rank-sum test).
Optic capture without anterior vitrectomy appears to be beneficial in preventing VAO in pediatric cataract surgery.
