Optic Capture Without Anterior Vitrectomy in Pediatric Cataract Surgery.

Purpose: To compare outcomes of 2 surgical techniques in children undergoing cataract surgery with intraocular lens (IOL) implantation: optic capture of IOL without anterior vitrectomy (AV) or in-the-bag IOL with AV.

Design: Prospective randomized controlled trial.

Methods: Patients were randomized to 2 groups: optic capture without AV (group 1) or in-the-bag implantation with AV (group 2). The following variables were compared: visual axis opacification (VAO), inflammatory deposits on IOL surface, anteroposterior synechia, IOL tilt and decentration, lenticular astigmatism, refractive prediction error, and posterior segment complications.

Results: Fifty-one eyes of 37 children were investigated with a mean follow-up of 20.1±8.5 months. Group 1 and group 2 had mean ages of 59.2±32.6 and 46.5±21.9 months, respectively (P = .104). Three eyes in group 1 and 2 eyes in group 2 developed VAO (P = .656). Two eyes in group 1 and 5 eyes in group 2 developed anteroposterior synechia (P = .291). Six eyes in group 1 and 11 eyes in group 2 had inflammatory deposits on the IOL (P = .233). Both groups had similar IOL tilt and decentralization (for all meridians, P > .05). The absolute refractive prediction error was 0.55±0.34 diopter (D) and 0.53±0.3 D, respectively (P = .294). Each group had 1 eye with intraocular hypertension (P = .932).

Conclusion: The optic capture method was similar to the conventional technique in the quantitative evaluation of comprehensive data such as visual axis opacification, inflammatory sequelae, refractive outcomes, and IOL stability. The optic capture technique is an appealing option for pediatric cataract surgery because it eliminates the requirement for vitrectomy.
