Abstract

PURPOSE
In this study, the visual performance and patient satisfaction one year after monovision cataract surgery and the results after 2 months.
METHODS
Thirty patients who had bilateral cataract surgery between February 2010 and January 2014 treated with monovision therapy and received postoperative examinations for at least one year after surgery were enrolled in the present study. The eye with the more severe cataract had the surgery first and was corrected for distance vision targeted at emmetropia. The fellow eye was operated for near vision targeted to -1.50~-2.50 diopter (D) range considering the patient's need for near task and preoperative refractive errors 2-4 weeks after the first operation. Binocular uncorrected distance visual acuity (UCDVA), uncorrected near visual acuity (UCNVA), spherical equivalent, anisometropia, stereopsis, patient satisfaction for far and near distance, and spectacle dependence were evaluated preoperatively and two months and one year postoperatively.
RESULTS
The mean age of patients was 71.9 years. Two months and one year after the surgery, the binocular UCDVA (log MAR) were 0.03 ± 0.10 and 0.08 ± 0.14, UCNVA were 0.21 ± 0.15 and 0.25 ± 0.14, anisometropia were 1.28 ± 0.68 and 1.29 ± 0.76 D, and stereopsis were 301.67 ± 251.28 and 251.67 ± 269.28 arcsec, respectively. One year after the surgery, the number of patients answering "˜Better' or "˜Much better' for distant vision was 27 (90%) and for near vision 22 (73.3%); 11 patients (36.7%) answered "˜Not dependent on spectacles at all'.
CONCLUSIONS
Monovision is an effective method to correct presbyopia after bilateral cataract surgery. Visual performances and patient satisfaction at one year after cataract surgery were not different compared with those at two months.
