SUMMARYWe have analysed the refractive results of corneal triple procedures (penetrating keratoplasty with extracapsular cataract extraction and posterior chamber intraocular lens implantation) in 52 ey es of 47 patients with a mean follow-up of 39 months. The patients were predominantly old and female and most received unilateral surgery. The contralateral acuity was 6/24 or worse in more than 50%
1985.The hospital records were examined and data extracted to a spread-sheet. Data sought were (1) patient identifiers, (2) epidemiological data including age, sex and distance from home address to Moorfields, and (3) cause of corneal opacity, refractive outcome, complications and rejection episodes, and whether further surgery was required.Where the data was available, pre-morbid refractions were noted. Pre-operative acuity of both eyes and details of bio metry (if any) were noted, as was suture technique and other operative details. Post-operatively, the numbers of clinic visits during the first year's trimesters and second year's semesters were recorded. 'Final' refraction was defined as a stable refraction (less than 0.5 dioptre change) for two successive clinic visits, or the latest refraction if follow-up exceeded 2 years. This data-base included the parameters shown in Table 1. The data were then analysed.
