Purpose:
To examine the collection of data from the corneal grafts performed between 1995 and 2000, thus providing a long term follow-up.
Methods:
Records of corneal grafts were made according to the following design and divided into three basic groups: 1a) donor data: age, storage time, endothelial density, ABO group; 1b) recipient data: age, ABO group, sight threatening pathology, diagnosis, visual acuity, corneal oedema, inflammation, vascularisation; 2) surgery data: surgery type, graft size, suture, intraocular lens, vitrectomy, complications; 3) data at first month and at each year follow-up: visual acuity, astigmatism, endothelial density, graft rejection and complications. A retrospective study of data collection percentage was performed.
Results:
Although 100% of data from donors and recipients was collected, some data such as ABO group was not available in all cases. First indication was keratoconus and bullous keratopathy. Mean visual acuity at first year was 0.31, collected in 60% and endothelial density, 2,223 cls/mm2, available in 26.6 percent.
Conclusions:
A good basic data collection improves the long-term follow-up for corneal grafts. Further analysis in the future of this data will be helpful for clinical audit.
