Objective:

To discuss the surgical techniques for pterygium removal and their outcomes, particularly focusing on a combined approach using conjunctival autograft and amniotic membrane graft.

Approach:

• Surgical Techniques: The article emphasizes the use of a combined conjunctival autograft (CAG) and amniotic membrane graft (AMG) approach for pterygium excision, detailing the procedure and materials used.
• Pre- and Postoperative Management: It outlines the importance of managing inflammation pre- and postoperatively with topical steroids and antibiotics, as well as patient counseling on sun protection and eye care.

Key Findings:

• Recurrence rates for pterygium excision can be as high as 18%, influenced by surgical technique and patient demographics.
• The combined CAG and AMG approach has shown recurrence rates of around 1% and excellent cosmetic outcomes in nearly 90% of patients.
• Preoperative inflammation management is crucial for minimizing recurrence risk.

Interpretation:

The combined CAG and AMG approach is preferred for its low recurrence rates and favorable cosmetic results, although caution is advised in specific patient populations.

Limitations:

• The study does not provide a comprehensive analysis of all surgical techniques available for pterygium removal.
• Specific patient conditions, such as glaucoma or double pterygium, may limit the applicability of the combined approach.

Conclusion:

Pterygium excision requires a meticulous approach tailored to individual patient needs to achieve optimal outcomes.
