Abstract Details


To find out the visual performance and patient satisfaction after 1 year of monovision cataract surgery and compare them with the results after 2 months of surgery. Then to compare the differences between conventional monovision and crossed monovision group.


Department of Ophthalmology, Konkuk University Medical Center, Seoul, Republic of Korea.


Patients had bilateral cataract surgery between February 2010 and January 2014, using the monovision therapy and received postoperative examination for at least one year after surgery. The eye with the more severe cataract had the surgery first and was corrected for distance vision targeted to 0 ~ -0.50D range. The fellow eye was operated for near vision targeted to -1.50 ~ -2.50D range considering patients’ near task 2~4 weeks after the first operation. Binocular uncorrected distance visual acuity(UCDVA), uncorrected near visual acuity(UCNVA), refractive error, stereopsis, patient satisfaction, and spectacle dependence were examined preoperatively, 2 months and 1 year postoperatively.


The study enrolled 23 patients with a mean age of 71.8 years. A year after the surgery, the binocular UCDVA(logMAR) was 0.09±0.15, UCNVA was 0.27±0.15, stereopsis(seconds of arc) was 196.09±214.66. The rate ‘Better’ or ‘Much better’ for distant vision were 22(96%), for near vision were 16(70%). The rate of ‘Do not dependent to spectacles’ were 7(31%). There were no significant differences in postoperative UCDVA, UCNVA, refractive error, and stereopsis between conventional monovision(N=10) and crossed monovision(N=13).


Monovision is an effective method to correct presbyopia after bilateral cataract surgery. Visual performance and patient satisfaction at 1 year after cataract surgery were not different compared with those at 2 months. There were no significant differences between conventional and crossed monovision group.
