The correct choice of synthetic sutures is based on their unique properties that allow for predictable tensile strength. Synthetic sutures are designed using materials like nylon or polypropylene, which can provide consistent and reliable strength during the healing process. This predictability is crucial in ophthalmic procedures, where the integrity of the closure and the potential for healing complications can significantly affect patient outcomes.

In contrast, plain gut sutures, which are derived from animal tissue, can have variable tensile strength due to their biological nature and can absorb at different rates, leading to unpredictability in how long they maintain their holding strength. Absorbable sutures also vary in their absorption rates and tensile strength, making their predictability less reliable compared to synthetic options. Non-absorbable sutures, while providing strong support, may not always be suited for specific ophthalmic applications where prolonged tensile strength is not necessary and could complicate future surgeries.

Overall, synthetic sutures offer a balance of strength, predictability, and suitability for delicate surgical procedures, making them the preferred choice for ensuring proper tissue approximation and healing.
