Congenital cataract is a major cause of visual impairment in children, with a prevalence of 3 to 4.5 in 10,000 live births. Without immediate treatment, visual prognosis is poor due to the effects of deprivation amblyopia.
Early removal of congenital cataract (before 6 weeks of age for unilateral and 10 weeks of age for bilateral) and aggressive treatment for amblyopia provides the best visual outcome. Current options for vision correction after cataract removal are implantation of intraocular lenses (IOLs) or leaving the infants aphakic and correcting them optically with glasses or contact lenses.
High plus spectacles are heavy and awkward on the small faces of infants and children. Moreover, the optics decrease the visual field and cause prismatic effects, resulting in poor vision. Aphakic glasses are reserved for when parental cooperation with contact lenses is suboptimal (Baradaran-Rafil et al, 2014).
IOLs Versus Contact Lenses
The implantation of IOLs for treatment of aphakia is controversial in younger children and infants). The infantile eye requires a smaller-diameter IOL that may lead to IOL luxation into the vitreous cavity during growth. Additionally, there is uncertainty in predicting the correct power of the IOL in rapidly growing eyes.
Contact lenses are a great choice for correction if aphakic because they are easily changed to accommodate fast-growing eyes of children. Types of contact lenses that are available to fit pediatric aphakia include GP, hydrogel, silicone hydrogel, and silicone elastomer lenses.
