Which procedure allows for iris opening improvement as per CPT code 66762?

1. Iridotomy

2. Iridoplasty

3. Evisceration

4. Enucleation

The correct answer is: Iridoplasty

Iridoplasty is a procedure specifically designed to improve the iris opening, which is crucial for managing certain types of conditions affecting the eye. This procedure involves the use of laser surgery to modify the shape of the iris and can help to reduce issues such as peripheral anterior synechiae or other conditions that cause the iris to close off, impairing the flow of aqueous humor. The designation of CPT code 66762 specifically refers to iridoplasty, emphasizing its role in enhancing the size of the iris opening. This is particularly beneficial when there is a requirement for improved fluid drainage within the eye, thus potentially helping to prevent elevated intraocular pressure. Other listed procedures do not directly relate to iris opening improvement. Iridotomy is aimed at creating a hole in the peripheral iris to allow fluid to flow between the anterior and posterior chambers, which is different from modifying the iris size. Evisceration refers to the removal of the contents of the eye while leaving the scleral shell intact, often performed for severe intraocular disease, and enucleation is the complete removal of the eyeball. These procedures do not pertain to enhancing the iris opening as iridoplasty does. Understanding the distinctions among these procedures is essential for accurate coding and effective communication in
