A cataract in a baby or young child is a paediatric ophthalmic emergency. Unlike cataract in adults, the issue is not just the opacity — it is what the opacity does to the developing visual system. Any prolonged obstruction of light reaching the retina during the first years of life can cause amblyopia (lazy eye) that no later surgery will fully reverse. Suraj Eye Institute has long offered specialist paediatric cataract care to children from Vidarbha and Central India.

Classification of Paediatric Cataract

By timing

• Congenital — present at birth or within first 3 months
• Infantile — developing in the first year of life
• Juvenile — developing later in childhood

By morphology

• Nuclear cataract
• Lamellar (zonular) cataract — the commonest hereditary type
• Sutural and Y-sutural cataract
• Polar (anterior or posterior) cataract
• Posterior lentiglobus — often unilateral, progressive
• Membranous and persistent fetal vasculature (PFV) associated cataract
• Traumatic and rubella-associated cataract

Causes

• Genetic — autosomal dominant inheritance is common; often bilateral
• Intrauterine infection — TORCH (particularly rubella), can be associated with microphthalmos and cardiac anomalies
• Metabolic — galactosaemia (urgent to diagnose), hypoglycaemia, hypocalcaemia
• Syndromic — Down syndrome, Lowe syndrome, Alport, Hallermann-Streiff and others
• Prematurity and its complications
• Trauma — important cause in older children
• Idiopathic — about one-third have no identifiable cause

Detection — the Red Reflex Test

Every newborn should have a red reflex test — shining a bright light at both pupils from arm’s length. A clear, symmetrical red reflex is normal; absence, whiteness or asymmetry warrants specialist referral. Suraj Eye Institute supports paediatricians and neonatologists across Nagpur with urgent paediatric ophthalmic review.

Timing of Surgery

The visual system is most sensitive in the first few months of life. Recommended timing for dense, visually significant cataract:

• Unilateral dense cataract — ideally operated within the first 4–6 weeks
• Bilateral dense cataract — within the first 8–10 weeks, both eyes operated close together
• Partial / non-visually significant cataract — observation with refraction, occlusion therapy and monitoring

Surgical Approach

Paediatric cataract surgery differs significantly from adult surgery. Standard steps include anterior capsulotomy, lens aspiration, posterior capsulotomy (PCCC) and anterior vitrectomy — because unlike in adults, the posterior capsule almost always opacifies rapidly in children. Decisions on primary or secondary IOL implantation are individualised based on age, ocular size and expected growth. More detail on our paediatric cataract surgery page.

After Surgery — the Long Road Back to Good Vision

Surgery is only the beginning. Paediatric cataract outcomes depend heavily on:

• Accurate refraction — appropriate glasses or contact lens correction
• Amblyopia therapy — occlusion (patching) of the better eye
• Monitoring for glaucoma — a known late complication of infant cataract surgery
• Monitoring for posterior capsule opacification (in secondary IOL cases)
• Long-term follow-up — lifelong, ideally with the same specialist team
