Which statement about radial keratotomy is FALSE?

Which statement about radial keratotomy is FALSE?

• A. Incisions are superficial
• B. It requires careful incision placement
• C. It involves excision of the corneal tissue
• D. It does not involve grafting with donor corneal tissue

Answer: (C)

Radial keratotomy is a surgical procedure aimed at correcting vision issues, particularly myopia. In this procedure, several radial incisions are made in the cornea to change its shape and improve focusing. The correct response identifies a statement that inaccurately represents the nature of the procedure. The specific statement regarding the excision of corneal tissue is false because radial keratotomy does not involve the removal of corneal tissue, but rather, it creates incisions that alter the shape of the cornea without excising tissue. These incisions are designed to be superficial and strategically placed to modify corneal curvature effectively. The absence of tissue removal distinguishes radial keratotomy from other procedures that might involve resecting or excising corneal tissue, such as laser-assisted surgeries. Additionally, the procedure does not require grafting with donor corneal tissue, as it is intended to modify the existing cornea rather than replace it. Understanding these distinctions is crucial when assessing the principles and techniques involved in radial keratotomy versus other surgical interventions for refractive errors.
