**Core Concept**
Treatment of cataract in infants involves addressing the visual deprivation caused by the opacity in the lens, which can lead to amblyopia (lazy eye) and lifelong visual impairment. This requires a pharmacological and surgical approach to restore vision and promote normal visual development.

**Why the Correct Answer is Right**
In infants, cataract surgery is typically performed under general anesthesia, and an intraocular lens (IOL) is implanted in the capsular bag to correct refractive errors. The goal is to remove the opaque lens and replace it with a clear one to allow light to pass through and reach the retina, promoting normal visual development. The surgery is often accompanied by topical corticosteroids and antibiotics to prevent inflammation and infection.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not address the underlying issue of cataract in infants. Infants with cataracts require surgical intervention to remove the opaque lens and restore vision.
**Option B:** This option is incorrect because it refers to a treatment for other conditions, such as glaucoma or uveitis, which are not relevant to cataract treatment in infants.
**Option C:** This option is incorrect because it is a treatment for adult cataracts, which may involve phacoemulsification, but is not suitable for infants.

**Clinical Pearl / High-Yield Fact**
Infants with cataracts require prompt surgical intervention to prevent amblyopia and promote normal visual development. A delay in treatment can lead to irreversible visual impairment.

**Correct Answer: A. Surgery with intraocular lens implantation**
