Visual results in repeat penetrating keratoplasty.

Summary
Visual prognosis after repeat penetrating keratoplasty (corneal transplant) is limited. Most eyes needing one regraft achieved good vision, but multiple repeat transplants rarely restored sight to 20/100 or better.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Visual Rehabilitation
Background:
- Repeat penetrating keratoplasty is performed when initial corneal grafts fail.
- Understanding visual outcomes after regrafts is crucial for patient counseling and surgical planning.
Purpose of the Study:
- To evaluate the visual prognosis following repeat penetrating keratoplasty.
- To compare visual acuity outcomes between single and multiple regrafts.
Main Methods:
- Retrospective chart review of patients undergoing repeat penetrating keratoplasty.
- Analysis of best corrected visual acuity (BCVA) at follow-up.
- Categorization of eyes based on the number of regrafts (one vs. multiple).
Main Results:
- 18 of 29 eyes required one regraft; 11 required multiple regrafts.
- Six of 18 eyes (33.3%) with one regraft achieved BCVA of 20/100 or better after 15.7 months.
- Only one of 11 eyes (9.1%) with multiple regrafts achieved BCVA of 20/100 or better after 27.5 months.
Conclusions:
- Single repeat penetrating keratoplasty offers a reasonable chance of visual recovery.
- Multiple repeat penetrating keratoplasties have a significantly lower success rate for achieving good visual acuity.
