Abstract
UBM measured changes in anterior chamber depth following pediatric IOL surgery with optic capture
Highlights
The technique of posterior capture with optic capture was first described by Gimbel and DeBroff in 1994.1 The main principle of this technique involves capturing the IOL optic through a posterior continuous curvilinear capsulorhexis (PCCC) opening leaving the haptics in the capsular bag.[1]
This study is a prospective evaluation of three patients with developmental cataracts who underwent cataract surgery consisting of posterior curvilinear capsulorhexis with optic capture and anterior vitrectomy
All Ultrasound Biomicroscopy (UBM) measurements were performed by the same operator: JC Ramos-Esteban
Summary
The technique of posterior capture with optic capture was first described by Gimbel and DeBroff in 1994.1 The main principle of this technique involves capturing the IOL optic through a posterior continuous curvilinear capsulorhexis (PCCC) opening leaving the haptics in the capsular bag.[1]. By placing the IOL optic posterior to the posterior capsulorhexis opening an increase in anterior chamber depth may require an adjustment in IOL power calculation. Anterior chamber depth determined by postoperative IOL position can lead to an error in IOL power calculation and has been shown to be one of the principal errors in IOL power calculations.[7,8] The purpose of this paper is to study changes in anterior chamber depth (ACD) with Ultrasound Biomicroscopy (UBM) before and after pediatric cataract surgery with the technique of posterior curvilinear capsulorhexis with optic capture and anterior vitrectomy, and compare to the fellow eye in which no surgery or an IOL was positioned in-the-bag without capture
