What is TRUE about the use of plain gut sutures?

  1. The sutures have a low tendency toward tissue vascularization

  2. The sutures provide strong tensile strength predictability

  3. The sutures are absorbable

  4. The sutures are synthetic

The correct answer is: The sutures are absorbable

Plain gut sutures are absorbable sutures made from the submucosal layer of sheep intestines. This means that over time, the body will naturally break down and absorb the suture material, eliminating the need for suture removal. This property makes them a convenient choice for ophthalmic surgeries.
