Quality of life and its infuencing factors in patients after keratoprosthesis implantation

Objective To determine the quality of life (QOL) and influencing factors in patients after keratoprosthesis(KPro) implantation using the National Eye Institute Visual Function Questionnaire25 (NEI-VFQ-25). Methods Clinical data about 99 patients underwent KPro implantation in our hospital from December 2005 to December 2015 were retrospectively analyzed. They were divided into 3 groups according to visual acuity (VA) (≥ 0.3, 0.05-0.3, < 0.05) on the basis of the vision injury criterion noted by WHO in 1973. Results The total QOL score were 65.63±13.35 in patients with vision better than 0.3, 44.23±10.61 in low vision group, and 20.97±5.77 in blind patients. Conclusion It suggests that QOL of patients underwent KPro implantation is poor and it is signifcantly correlatied with visual acuity and personal income.
