Aim: The aim of the study was to analyse the effect of various donor parameters on visual outcome after optical penetrating keratoplasty (OPK). Methods: Data were reviewed retrospectively for the patients who underwent OPK. Donor factors which included the age and sex of the donor, cause of death, death to enucleation time (DET), death-to-preservation time (DPT), enucleation to utilisation time (EUT), total time (TT) in hours and recipient factors like age, sex, intraocular pressure (IOP) and best corrected visual acuity (BCVA) were analysed from preoperative and postoperative visits at range of 7-9 months. According to BCVA patients were divided into three groups as group 1,2 and 3 with BCVA of ≥6/18 ,6/24-6/60 and <6/60 respectively. Results: Donor variables like gender, cause of death, EUT and TT did not show any effect on the BCVA. The difference between DET of ≤3, >3hours and DPT of ≤4, >4 hours showed significant effect on BCVA with p value of 0.024 and 0.050 respectively. Average logarithm of minimal angle of resolution (log MAR) BCVA at last follow up was 0.75. According to BCVA maximum patients 55 (60.43%) fell into group 2. BCVA improved from the pre operative status in 81 (89.01%) of eyes. Conclusions: Donor variables shows impact on the visual outcome during short span of post OPK follow ups till nine months. Both donor and eye bank variables influence quality of donor corneas, outcome and complications of PK. |
