Tion for PK nationally (23.5 ) (table three), it was the second most typical indication within this series (15 ) as it was previously amongst 1975 and 1990 (16.8 ).four Keratoconus was far more frequent in males in our series and equivalent preponderance has been reported previously,20 26 although female predominance has also been described.278 Keratoconus has and continues to be a leading indication for PK elsewhere1 three 5 9 21 290; on the other hand, together with the resurgence of interest in lamellar techniques314 also because the introduction of intracorneal rings,35 this may decrease in time. Fuchs’ endothelial dystrophy was the third most typical indication at 9.3 . The reported rates of Fuchs’ endothelial dystrophy are hugely variable3 8 102 367 and almost certainly as a result of distinct demographic pools and referral patterns.

While bullous keratopathy (aphakic and pseudophakic) has drastically declined nationally from 20 in 1990 to 9 in 1998 (table 3), this has not changed substantially as an indication for PK at our institution. Nevertheless, as anticipated with increased use of intraocular lenses in cataract surgery inside the mid 1980s, aphakic bullous keratopathy declined and PBK enhanced in our series (fig three). The incidence of PBK inside the UK has been markedly reduced than North America. Sharif et al4 reported two among 1975 and 1990.Aripiprazole Involving 1990 and 1999, PBK accounted for 7.6 within the UK (table 3) as well as the figure was identical in our series.PMID:28440459 In North America PBK became a leading indicator for PK in some series (Wills Eye Hospital 22.9 ,12 Doheny Eye Institute 24.8 eight) and was a result on the initial enthusiasm for lens implantation in cataract surgery, specifically with anterior chamber closed loop implants and iris clip lenses. The UK, in its very conservative strategy and slower acceptance of intraocular lenses, avoided this epidemic. Interestingly, despite the fact that the national rate of PBK remained precisely the same over the 10 year period (table three), at our institution the rate of PBK enhanced (fig 2B)–possibly reflecting a rise in referral of postcataract extraction complications requiring anterior segment reconstruction.
