Scleral ring as template for corneoscleral graft
American Journal of Ophthalmology
|February 1, 1978
Summary
A corneoscleral graft using a scleral ring template was performed for a patient with severe corneal ectasia. The procedure resulted in a retrograft membrane and corneal edema, with limited visual recovery.
Area of Science:
- Ophthalmology
- Regenerative Medicine
Background:
- Corneal lacerations can lead to bacterial keratitis and subsequent corneoscleral ectasia.
- Corneoscleral ectasia poses a significant challenge in restoring ocular integrity and visual function.
Observation:
- A 19-year-old female presented with corneoscleral ectasia in the right eye following treatment for bacterial keratitis.
- A 15-mm diameter scleral ring was utilized as a template for creating uniform donor and host corneoscleral buttons.
Findings:
- The corneoscleral graft was successfully performed using the scleral ring template.
- Postoperative examination revealed a retrograft fibrous membrane with corneal edema.
- Visual acuity was recorded as 6/60 (20/200) with an intraocular pressure of 16 mm Hg one year after surgery.
Implications:
- This case highlights a potential surgical approach for managing corneoscleral ectasia.
- Further research is warranted to optimize graft outcomes and minimize complications like fibrous membrane formation.
- The technique demonstrates the feasibility of using templated grafts for complex ocular surface reconstruction.
