Abstract Details
Purpose:
Anatomical and functional results of posterior lamellar keratoplasty performed in patients between 2006-2015 in Department of Ophthalmology in Lublin, Poland
Setting:
Department of Ophthalmology, Medical University, Lublin, Poland
Methods:
Retrospective analysis of patients medical charts. Parameters evaluation: graft survival, early and late complications, surgery indications, visual acuity, endothelial cell loss and analysis of changes due to the method modification
Results:
Among 838 transplantation lamellar keratoplasty was done in 24,11%, full-thickness grafts in 53,94%, tectonic patch in 6,44%, anterior lamellar keratoplasty in 6%, combined procedure in 9,11%.Endothelial cell loss after 3 months-43,75%. Along 10 years technique was modified by introducing suturing incisions and 6 o’clock iridotomy- drop in rebubbling rate from 35,7% to 4,3% and no pupillary block. In 2014 microkeratome dissection was introduced. In 68,42% of cases transplantation was done in bullous keratopathy after cataract extraction, trabeculectomy, Ahmed valve implantations and pars plana witrectomy.VA before surgery: HM to 0,4, at the follow-up: CF to 1,0. Early complications: graft failure, graft detachment, pupillary block; late complications: anterior synechiae, endothelial cell loss, graft rejection.
Conclusions:
Compared to full thickness graft posterior lamellar keratoplasty is characterised by lower rate of serious complications such as graft rejection and faster visual rehabilitation. However this procedure might be modified along the time due to new techniques and equipment possibilities what can lead to different results. Moreover very high endothelial cell loss up to 50% within first 3 months after surgery requires very good or excellent endothelium in the donor cornea.
