The absorbable sutures in cataract surgery.

Area of Science:

• Ophthalmology
• Surgical Materials Science

Background:

• Cataract extraction is a common surgical procedure to restore vision.
• Suture materials are crucial for wound closure and healing post-surgery.
• Chronic catgut sutures have been considered for their potential benefits in ocular surgery.

Observation:

• A case involving 6-0 chronic catgut sutures persisting for over 2 years and 8 months after cataract extraction is detailed.
• The persistent sutures led to recurrent episodes of conjunctival inflammation and iritis.
• This prolonged presence highlights a significant complication associated with chronic catgut.

Findings:

• Chronic catgut sutures are unsuitable for routine cataract surgery due to their prolonged persistence.
• The persistent sutures can elicit chronic inflammatory responses, impacting ocular health.
• Despite complications, chronic catgut offers distinct advantages in specific surgical scenarios.

Implications:

• The use of chronic catgut sutures in cataract surgery should be carefully considered and limited to selected cases.
• Patients with anxiety or those for whom suture removal is challenging may benefit from these sutures.
• Further research into alternative long-lasting, biocompatible suture materials for ophthalmic procedures is warranted.
