A study to evaluate the keratoanalyzer in success of penetrating kertoplasty

Abstract

Aims: To evaluate donor cornea by using eye bank specular microscope and evaluate outcome of keratolplasty according to the graft condition. Materials and Methods: This was a prospective study of 30 patients who undergone keratoplasty. Donor cornea was evaluated by slit lamp biomicroscopy and after preservation in MK media, evaluated using eye bank specular microscope. Final decision of transplantation was made on grading of specular microscopy. All patients undergone penetrating keratoplasty and post-operative outcome was measured. Results: In our study majority of donors were in age group of 21-40 years. Endothelial cell count of >3000 cells/mm 2 was observed in 60% cases, while 2500-3000 cells/mm 2 in 26.67% cases. The reason for penetrating keratoplasty were corneal opacity or scarring (40%), PBK (23.33%), acute infective keratitis (13.33%), regraft due to graft failure (10%), ABK (10%) and corneal dystrophy (3.33%). Postoperative clear graft was seen in 60% cases while cloudy in 20% and opaque in 20% cases. It was observed that large number of recipients (46.66%) had post-operative visual acuity more than 6/60. Conclusions: Though tissue utilization can be optimized with the use of eye bank specular analyzer, final outcome depends on multiple factors. Few tissues of older age can be utilized if having good endothelial count.
