Ophthalmic Surgery
|January 1, 1976
Summary
This study presents a lamellar corneoscleral keratoplasty technique to prevent pterygium recurrence. The method proved effective in fifteen eyes, showing no regrowth after up to four years.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Corneal Surgery
Background:
- Recurrent pterygium poses a significant challenge in ophthalmic surgery.
- Existing treatments have varying success rates in preventing regrowth.
- The need for effective surgical strategies to manage severe recurrent pterygium is critical.
Purpose of the Study:
- To describe a lamellar corneoscleral keratoplasty technique for recurrent pterygium.
- To evaluate the efficacy of this technique in preventing pterygium regrowth.
- To postulate the role of graft placement and barrier function in preventing recurrence.
Main Methods:
- A lamellar corneoscleral keratoplasty technique was employed.
- Graft placement accuracy was emphasized.
- The graft's function as a tissue barrier was assessed.
Main Results:
- Fifteen eyes with severe recurrent pterygium were followed for six months to four years.
- No further pterygium recurrences were observed in any of the treated eyes.
- The technique demonstrated a high success rate in preventing regrowth.
Conclusions:
- Lamellar corneoscleral keratoplasty is a viable surgical option for recurrent pterygium.
- Accurate graft placement and its barrier function are key to preventing recurrence.
- This technique offers a promising solution for managing severe recurrent pterygium.
