Binocular Vision after Cataract Surgery in Children - Long Term Follow up

Overview

Purpose:
Toevaluate quality of binocular vision in dependence ontype of cataract,time of surgery and type of aphakic correction with minimal 5 years follow up.Methods: 127 children divided into 3 groups: Group A - 24 children with monolateral congenital cataract, Group B - 56 children with bilateral congenital cataract,Group C -47 children with traumatic cataract. Binocular vision results wereevaluated 5-10 years after cataract surgery subordinated on the type of aphakic correction- PC IOL, contact lenses, spectacles, type of cataract (congenital monoor bilateral, traumatic) and time of cataract surgery.Results: Group A: Binocular vision in 56% children with cataract surgery in thefirst 3months of age and only 20% of binocular vision in children operated later.Binocular vision results in dependence on aphakic correction (46% in contact lenssubgroup, 44% in PCIOL subgroup without statistically significant diferences.Group B: Binocular vision in 76% of children operated in the first 3months of age,and 79% of children operated later. Binocular vision in 68%of children in spectacleaphakic correction subgroup, 67% of children in contact lenses subgroup, and 75%of children in primary or secondary implanted PC IOL subgroup.Group C: Binocular vision in 80% of children with contact lenses subgroup, andin 84% of children with implantation PC IOL.Conclusion: Better results of binocular vision quality have children with cataractextraction in the first three months of age then children operated later in groupwith monolateral congenital cataract.Primary or secondary implantation of PC IOL was find to the better aphakiccorrection for the binocular visual results in the groups with bilateral congenitalcataract andtraumaticcataract thanothertypes of aphakiccorrection. Amblyopiais a major determinate of visual outcome in childhood cataract. The timing ofsurgery - the early cataract removal will continue to be more important than themethod of aphakic optical correction, especially in the case of monolateral congenital cataract.
