[Suture technic in perforating keratoplasty and postoperative astigmatism]

Area of Science:

• Ophthalmology
• Corneal Surgery

Context:

• Perforating keratoplasty involves corneal transplantation.
• Suture techniques significantly impact surgical outcomes.
• Astigmatism is a common complication affecting visual acuity post-keratoplasty.

Purpose:

• To compare the efficacy of interrupted versus continuous diagonal stitches in perforating keratoplasty.
• To evaluate the impact of different suturing methods on postoperative astigmatism and vision.

Summary:

• A study of 25 patients undergoing perforating keratoplasty compared interrupted and continuous diagonal stitches.
• Continuous diagonal suturing resulted in more uniform corneal adaptation, less trauma, and easier stitch removal.
• This technique also facilitates better management of postoperative astigmatism.

Impact:

• Recommends continuous diagonal sutures for improved outcomes in corneal transplantation.
• Highlights the importance of suture technique in minimizing astigmatism and optimizing visual results.
• Provides insights for surgical technique refinement in keratoplasty procedures.
