Abstract
PURPOSE: To assess the vision-related quality of life (VQoL) for patients with advanced keratoconus (KC) after primary keratoplasty. METHODS: This was a cross-sectional study, undertaken at the King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia, in December 2015. Adults (aged 22-75 years) were interviewed via telephone with regard to their VQoL, on the average, 5 years after undergoing primary keratoplasty for advanced KC. VQoL was measured using the Visual Functioning Index (VF-14, Arabic version). The relationship between VQoL and different demographic and clinical factors was evaluated using linear regression. RESULTS: Ninety-five adults participated in the study (54.7 % males; mean age at the interview = 32.05 ± 7.18 years). Eighty-seven (91.6%) of them had undergone PKP. The overall mean VF-14 score was 86.19% (SD: 12.91). VF-14 score was significantly lower for individuals with higher log average K (beta coefficient, -28.32; 95% confidence interval [CI], -55.59 to -1.04; p = 0.042) and hazy graft (beta coefficient, -12.76; 95% CI, -21.16 to -4.36; p = 0.003) adjusting for the effect of keratoplasty technique and BCVA in the better eye at the last follow up. CONCLUSION: This study suggests that most patients with advanced keratoconus had satisfactory VQoL after primary keratoplasty. Certain subgroups may benefit less substantially than others and would need a particular attention.
