متن کاملPenetrating keratoplasty for keratoconus: complications and long-term success.
A series of 100 penetrating keratoplasties for keratoconus performed between 1968 abd 1986 were reviewed for long-term results. The mean follow-up was 6.1 years with a range of 4-16 years. The systemic associations and the postoperative complications were analysed. Grafting in cases associated with Down's syndrome had a higher incidence of complications. 93% of grafts remained clear and 81% ach...
