Distance vision, near vision and quality of life between preferred emmetropia and residual myopia in monofocal intraocular lens implantation- A Comparative study.

INTRODUCTION

This study was done to evaluate the visual acuity and quality of life in predicted emmetropia (EM) and predicted residual myopia (RM) patients following phacoemulsification with monofocal intraocular lens implantation.

MATERIALS AND

METHODS

This prospective comparative study was conducted in the ophthalmology clinic of the Universiti Sains Malaysia Hospital, Kelantan, Malaysia. Overall, 139 patients with senile cataract were randomised into EM and RM groups. At three months post-operatively, patients were assessed for distance and near vision, as well as quality of life using a modified VF-14 questionnaire.

RESULTS

Thirty-six patients (64.3%) in the EM group and 30 patients (52.6%) in the RM group (p = 0.209) showed good distance vision (LogMAR 0.3 or better). Fifty patients (87.7%) in the RM group and 27 patients (48.2%) in the EM group gained significantly higher satisfactory near vision (p < 0.05). The quality of life in both groups was good, with a mean modified VF-14 score of 94.5 (SD 2.68) for the EM group and 95.1 (SD 3.19) for the RM group (p = 0.286). Female patients scored significantly higher than males for total activities (p = 0.010) and distance vision-related activities (p = 0.001). The RM group had significantly better patient satisfaction for near vision-related activities compared to the EM group (p = 0.001). In particular, the item 'reading small print' was significantly better in the RM group (p = 0.003).

CONCLUSION

Patients in the predicted RM group gained more satisfactory near vision than patients in the EM group, with significantly better quality of life for near vision activities.
