Long-term outcomes of endothelial keratoplasty in Chinese eyes at a University Hospital

Background Endothelial keratoplasty (EK) is used increasingly for the management of cases with endothelial dysfunction. Long-term outcomes of the surgery are not widely reported in the literature. We report our experience of EK in Chinese eyes at a University teaching hospital. Methods Retrospective...

520			\|a Background Endothelial keratoplasty (EK) is used increasingly for the management of cases with endothelial dysfunction. Long-term outcomes of the surgery are not widely reported in the literature. We report our experience of EK in Chinese eyes at a University teaching hospital. Methods Retrospective analysis was performed for all cases of EK performed between 2005 and 2009. Data analyzed included indication for surgery, associated surgical procedures, complications, best-corrected visual acuity (BCVA) and overall graft survival. Results Overall, 22 eyes of 21 patients underwent EK (13 males, 8 females, mean age 71.8 ± 11.3 years). Pseudophakic bullous keratopathy was the leading indication for surgery (n = 12) followed by Fuchs’ endothelial dystrophy (n = 4), or both (n = 3). Other indications for surgery included failed penetrating keratoplasty (n = 2) and endothelial decompensation due to multiple surgeries (n = 1). Triple procedure was performed in 5 (22.7%) cases. Complications were noted in the form of postoperative interface hemorrhage (n = 2, 9%) and graft dislocation (n = 1, 4.5%). The mean postoperative endothelial cell density was 1069 ± 585.8 cells/$ mm^{2} $. The mean postoperative pachymetry was 675.8 ± 108.5 μm. The mean preoperative and postoperative intraocular pressure was 11.3 ± 3.2 and 13.9 ± 4.5 mmHg respectively. At the last follow-up (mean, 47.4 ± 13.7 months), BCVA was ≥20/70 in 9 (40.9%) cases. Causes of poor BCVA included primary graft failure (n = 4), graft decompensation (n = 4), advanced glaucoma (n = 2) and irreversible graft rejection (n = 2). Graft remained clear in 12 (54.5%) cases at the last follow-up. Average graft survival was 19.7 ± 17.7 months (median 17.5 months). Conclusions Nearly half of the EK grafts in our study survived over a period of five years. Graft failure, glaucoma and graft rejection were the main causes of poor graft survival.

The mean postoperative endothelial cell density was 1069 ± 585.8 cells/$ mm^{2} $. The mean postoperative pachymetry was 675.8 ± 108.5 μm. The mean preoperative and postoperative intraocular pressure was 11.3 ± 3.2 and 13.9 ± 4.5 mmHg respectively. At the last follow-up (mean, 47.4 ± 13.7 months), BCVA was ≥20/70 in 9 (40.9%) cases. Causes of poor BCVA included primary graft failure (n = 4), graft decompensation (n = 4), advanced glaucoma (n = 2) and irreversible graft rejection (n = 2). Graft remained clear in 12 (54.5%) cases at the last follow-up. Average graft survival was 19.7 ± 17.7 months (median 17.5 months).

Long-term outcomes of the surgery are not widely reported in the literature. We report our experience of EK in Chinese eyes at a University teaching hospital. Methods Retrospective analysis was performed for all cases of EK performed between 2005 and 2009. Data analyzed included indication for surgery, associated surgical procedures, complications, best-corrected visual acuity (BCVA) and overall graft survival. Results Overall, 22 eyes of 21 patients underwent EK (13 males, 8 females, mean age 71.8 ± 11.3 years). Pseudophakic bullous keratopathy was the leading indication for surgery (n = 12) followed by Fuchs’ endothelial dystrophy (n = 4), or both (n = 3). Other indications for surgery included failed penetrating keratoplasty (n = 2) and endothelial decompensation due to multiple surgeries (n = 1). Triple procedure was performed in 5 (22.7%) cases. Complications were noted in the form of postoperative interface hemorrhage (n = 2, 9%) and graft dislocation (n = 1, 4.5%). The mean postoperative endothelial cell density was 1069 ± 585.8 cells/$ mm^{2} $. The mean postoperative pachymetry was 675.8 ± 108.5 μm. The mean preoperative and postoperative intraocular pressure was 11.3 ± 3.2 and 13.9 ± 4.5 mmHg respectively. At the last follow-up (mean, 47.4 ± 13.7 months), BCVA was ≥20/70 in 9 (40.9%) cases. Causes of poor BCVA included primary graft failure (n = 4), graft decompensation (n = 4), advanced glaucoma (n = 2) and irreversible graft rejection (n = 2). Graft remained clear in 12 (54.5%) cases at the last follow-up. Average graft survival was 19.7 ± 17.7 months (median 17.5 months). Conclusions Nearly half of the EK grafts in our study survived over a period of five years. Graft failure, glaucoma and graft rejection were the main causes of poor graft survival.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Endothelial keratoplasty</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Keratoplasty</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Long-term outcomes</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kwok, Rachel PW</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Jhanji, Vishal</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cheng, Lulu L</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Rao, Srinivas K</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Eye and Vision</subfield><subfield code="d">London : BioMed Central, 2014</subfield><subfield code="g">1(2014), 1 vom: 01.
