To compare the advantages and disadvantages of continuous suture with suture and conventional Suture in primary pterygium surgery for autologous conjunctival graft fixation

Conditions

Primary Pterygium

Keywords

Outcome Measures

Primary Outcomes (4)

• Duration of surgery

  The date on which the surgery was performed

  Intraoperative

• Implant stability

  Whether the conjunctival graft is loose or detached

  Postoperative follow-up was performed 1 day and 1 week after surgery

• Postoperative discomfort

  The degree of discomfort after surgery was evaluated using the VAS Pain score Scale

  Postoperative follow-up was performed 1 day and 1 week after surgery

• Stitch removal time

  The date when the stitches were removed

  Postoperative follow-up was performed 1 week after surgery

Study Arms (2)

Continuous suture group

OTHER

Pterygium excision combined with autologous conjunctival transplantation was performed

Procedure: Compression continuous suture with suture crimping

Intermittent suture group

OTHER

Pterygium excision combined with autologous conjunctival transplantation was performed

Procedure: Conventional Suture with suture crimping

Interventions

Compression continuous suture with suture crimping PROCEDURE

Pterygium excision combined with autologous conjunctival transplantation was performed, and the continuous suture method with pressure lines was adopted during the operation

Continuous suture group

Conventional Suture with suture crimping PROCEDURE

Pterygium excision combined with autologous conjunctival transplantation was performed, and the traditional suture method was adopted during the operation

Intermittent suture group
