Participants
Participants included 71 infants who were diagnosed with a unilateral dense congenital cataract during the first 2 weeks of life, of whom 5 received a primary IOL and 66 were fitted with an aphakic contact lens after cataract extraction. Of the 66 who received an aphakic contact lens, 15 had an IOL implanted as a secondary procedure at a later date. In addition, 31 children with developmental cataracts participated, of whom 9 developed dense cataracts during infancy and had surgery by 6 months
Primary IOLs for Unilateral Dense Congenital Cataracts
Visual acuity maturation for pseudophakic and fellow eyes of infants who received a primary IOL after extraction of a unilateral dense congenital cataract at 3.8 ± 3.1 month of age is shown in Figure 1. At 6 months of age, the mean pseudophakic eye visual acuity was 0.925 logMAR (20/170). Visual acuity in the pseudophakic eye improved rapidly to 0.628 logMAR (20/85) by 1 year of age, when it approached the visual acuity of the fellow eye (0.530 logMAR, 20/70). After 1 year of age, visual acuity
Discussion
IOLs and aphakic contact lenses support similar visual acuity development in infants and young children treated for unilateral dense congenital cataracts. Contact lenses are the most common mode of aphakic optical correction in infants because they generally are well tolerated and because the power of the aphakic contact lens can be changed frequently to keep pace with the rapidly changing refractive error of the maturing aphakic eye. The data presented here suggest that IOLs, used in

Updates on managements of pediatric cataract
2019, Journal of Current OphthalmologyCitation Excerpt :Unlike adult cataract surgery, lens aspiration without instant IOL implantation is usual in infants, and most surgeons prefer not to implant IOL in this age group.60 Hypermetropic refractive error as a result of aphakia following a lensectomy in infancy requires contact lens correction or thick spectacle lenses to prevent amblyopia, especially in unilateral cataract.61,62 Some studies reported that visual outcome following primary IOL implantation in unilateral cataracts appear to be better compared with aphakia and contact lens correction, but this technique needs more secondary interventions than aphakic patients.63
