D After 4 years when entire ocular and orbital growth becomes normal

Ans. A [Immediately] Q

Congenital cataract - Timing of surgery

1. Bilateral dense - cataract requires early surgery (i.e. by 6 weeks of age Q) to prevent the development of stimulus deprivation amblyopia

2. Bilateral partial- cataract may not require surgery until later

3. Unilateral dense - cataract merits urgent surgery (within days Q) followed by aggressive anti-amblyopia therapyIt if the cataract is detected after 16 weeks of age then surgery can be delayed a lre because amblyopia is refractory

4. Partial unilateral - cataract can usually be observed or treated non surgically with pupillary dilatation and possibly part-time opposite eye occlusion to prevent amblyopia
