ABSTRACT
AIMS:
To report the 25-year longitudinal trends in indications and corneal transplantation techniques in New Zealand.METHODS:
Statistical analysis of prospectively acquired New Zealand National Eye Bank (NZNEB) electronic database from 1991 to 2015 inclusive. Subjects were recipients of corneal transplants in 62 centres supplied by the NZNEB. Main outcome measures were indications, recipient age and transplantation techniques.RESULTS:
From January 1991 to December 2015, NZNEB supplied tissue for 5574 corneal transplants, increasing annually from 89 (1991) to 290 (2015). Penetrating keratoplasty remained the most commonly performed technique throughout the 25-year period, although it decreased from 98.9% of all transplants in 1991 to 60.3% in 2015. There was a corresponding increase in deep anterior lamellar and endothelial keratoplasty over the most recent decade from 2.5% to 7.2% and 4.9% to 31.4%, respectively. Keratoconus remained the leading indication for keratoplasty through to 2015 (34.5%). Regrafts (23.1%) and Fuchs endothelial corneal dystrophy (17.0%) have become more common indications, while bullous keratopathy has become less common (10.8%). There was a bimodal distribution in age with peaks at 20-29 and 60-79â years. There was a reduction in recipients under age 40 and corresponding increase in the percentage of recipients aged 40-69.CONCLUSION:
Changing indications and increasing uptake of lamellar keratoplasty have been significant international trends over the last 25â years. However, New Zealand's corneal disease and population characteristics create unique longitudinal trends, with keratoconus remaining the leading indication and penetrating keratoplasty the leading technique from 1991 to 2015.Palavras-chave
