In ocular surgery, which of the following sutures is commonly avoided due to high tissue reaction?

In ocular surgery, polyester sutures are often avoided due to their tendency to provoke a significant tissue reaction. This is primarily due to the synthetic nature of polyester, which can elicit a more pronounced inflammatory response compared to other suture materials. The body's immune response to this type of suture may result in increased scarring and delayed healing, which are critical factors to consider in delicate ocular procedures where minimizing tissue trauma and optimizing healing are paramount.

On the other hand, silk sutures, while having their own disadvantages, are known for their excellent handling and knot security but can also induce a moderate tissue reaction. Vicryl and polydioxanone sutures are generally favored in ocular surgery due to their absorbable nature and the minimal inflammatory response they provoke, making them more suitable for intraocular and delicate tissues. Therefore, polyester’s high tissue reactivity makes it less desirable for use in ocular surgical procedures.
