Summary
This study analyzed 19 emergency corneal transplants (penetrating keratoplasties à chaud) in patients with severe corneal issues. While most infections were cleared, outcomes varied, with many patients achieving limited or poor visual acuity post-surgery.
Area of Science:
- Ophthalmology
- Transplantation Surgery
Background:
- Corneal perforation and imminent perforation pose significant risks to vision.
- Emergency corneal transplantation (penetrating keratoplasty à chaud) is a critical intervention for such cases.
Purpose of the Study:
- To evaluate the outcomes of emergency penetrating keratoplasty in patients with imminent or perforated corneas.
- To assess the success rates and complications associated with this urgent surgical procedure.
Main Methods:
- Analysis of results from 19 penetrating keratoplasties à chaud.
- Involved 18 patients with imminent perforation or perforated corneas.
- Infection eradication and graft survival were key parameters monitored.
Main Results:
- Infectious agents were eradicated in most cases, except for Acanthamoeba keratitis.
- Three grafts experienced secondary bacterial infections.
- Six eyes required repeat keratoplasty, with two ultimately enucleated.
- Visual acuity outcomes were varied: 32% achieved 5/10-10/10, 21% achieved 1/10-5/10, and 47% had less than 1/10.
Conclusions:
- Emergency penetrating keratoplasty can be sight-saving but carries substantial risks.
- Acanthamoeba keratitis presents a particular challenge for infection eradication.
- A significant proportion of patients experience suboptimal visual outcomes, necessitating further management or resulting in graft failure.
