AIM:To investigate the influence of monovision design of cataract surgery on the prognosis visual quality in cataract patients.

METHODS: Totally 84 cases cataract patients(168 eyes)who receiving cataract surgery were enrolled from February 2016 to February 2017 in our hospital to conduct a prospective study. According to the different near addition in the monovision design, patients were divided into low near addition group(1.25D-1.75D)and high near addition group(2.25D-2.75D), each group was 42 cases. At postoperative 6mo, the binocular uncorrected near visual acuity, uncorrected intermediate visual acuity, uncorrected distance visual acuity and stereoscopic vision were compared between two groups. The visual function survival quality score before and after treatment were compared.

RESULTS: The binocular uncorrected intermediate and distance visual acuity in the low near addition group respectively was 0.27±0.20, 0.09±0.08, and that in the high near addition group respectively was 0.29±0.25, 0.10±0.07, which had no statistically significant difference between two groups(P>0.05). The binocular uncorrected near visual acuity in the high near addition group was 0.03±0.06, which was significantly better than the low near addition group 0.07±0.04, the difference was statistically significant(P<0.05). Before the treatment, the visual function-14(VF-14)score in each two group respectively was 27.93±4.52, 28.24±4.91; after the treatment, VF-14 score in each two group respectively was 82.04±14.31, 81.22±13.70, which had no statistically significant difference between two groups(P>0.05). After treatment, the VF-14 score both significantly increased in the two groups(P<0.05). The proportion of patients with the normal stereoscopic vision, peripheral stereovision and macular stereovision in the low near addition group respectively was 47.6%, 31.0%, 21.4%; and that in the high near addition group respectively was 42.9%, 23.8%, 33.3%, which had no statistically significant difference between two groups(P>0.05).

CONCLUSION: Two kinds of near addition have similar advantages to cataract patients after cataract surgery on uncorrected visual acuity, the quality of visual function and stereopsis.
