Abstract

Background
This study was done to assess the relationship among multiple patient outcomes of cataract surgery perioperatively, 3-4 months and 12 months after surgery. The patient outcomes include changes in visual acuity(operated eye, better eye), visual function(VF-14), patient satisfaction, subjective satisfaction with vision, and subjective overall health status.
Methods
For the assessment of relationship, prospective study was performed with 92 patients who had undergone either one or both eye cataract surgery by 3 ophthalmologists practicing at a university hospital. Patients were interviewed. and clinical data were obtained. Doctors were questioned with self-entered questionnaire forms. Medical record was examined to understand surgery process. The survey was conducted at 4 stages : preoperatively, perioperatively, postoperative 3-4 months, and postoperative 12 months.
Results
The correlations within patient outcomes at 4 stages - the visual acuity of operated eye and that of better eye, patient satisfaction and VF-14, subjective overall health status and relative health status as against others - were found to be positively correlated. The change in the visual acuity of operated eye and better eye was correlated with VF-14 as well as with patient satisfaction. The change was also correlated with overall health status. However, the correlations between variables were decreased as the postoperative period got longer.
Conclusion
As for the postoperative clinical patient outcomes, VF-14 is acted to linker between visual acuity - clinical outcomes and overall health status - endpoint outcomes. Therefore. VF-14 is the index of patient-sided and disease-specific outcome for cataract surgery.
