**Core Concept**
The initial management of congenital lens dislocation or subluxation due to congenital lens antigen (also known as Marfan syndrome or homocystinuria) involves careful consideration of the underlying genetic disorder and its implications on ocular and systemic health. **Congenital lens dislocation** is often associated with Marfan syndrome, a genetic disorder affecting the body's connective tissue.

**Why the Correct Answer is Right**
The primary concern in managing congenital lens dislocation is to prevent further eye complications, such as cataract formation, secondary glaucoma, and retinal detachment. **Surgical intervention** is often necessary to stabilize the lens and restore vision. In cases of Marfan syndrome, a thorough ophthalmological examination and genetic counseling are essential to understand the prognosis and potential complications. The management of congenital lens dislocation typically involves **phacoemulsification or extracapsular cataract extraction**, followed by intraocular lens implantation.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not address the underlying congenital condition.
**Option B:** This option is incorrect because it does not consider the specific needs of patients with Marfan syndrome or homocystinuria.
**Option C:** This option is incorrect because it may not be appropriate for all cases of congenital lens dislocation, especially those requiring more complex surgical intervention.

**Clinical Pearl / High-Yield Fact**
When managing congenital lens dislocation, it is essential to consider the potential for systemic complications, such as aortic root dilation, and to refer patients to a multidisciplinary team, including ophthalmologists, geneticists, and cardiologists.

**Correct Answer: C. Phacoemulsification or extracapsular cataract extraction.**
