Purpose: A review of the results of intraocular lens implantation in a series of 21 infants under 12 months of age with congenital cataract
Methods: 26 eyes of 21 infants were reviewed all had undergone lensectomy and lens implant within a four year period Each had lensectomy by one surgeon IC Lloyd with biometry at the time of surgery. Long term follow up of visual, refractive and axial length changes are reported.The complete abscence of early onset glaucoma is encouraging
Results:Our results indicate that implantation to produce hypermetropic under-correction modified for age at surgery compensates for subsequent eye growth and in the long term approximates well to emmetropia in otherwise normal eyes. Under and over estimates of lens power are observed particularly in eyes with coexisting anomalies.The complete abscence of early onset glaucoma is encouraging.The main obstacle to successful visual outcome remains occlusion compliance. Capsule fibrosis and lens fibre proliferation may require secondary surgery
Conclusion:Ocular growth continues as expected following early surgery in otherwise normal eyes.Our longitudinal data shows near emmetropia by 24 months. With increasing raw data the development of formulae to calculate intraocular lens power should become possible. The future prospects for infant cataract management appear promising.
