| Summary: | AIM: To compare the visual related quality of life between patients who underwent binocular and unilateral AT LISA tri 839MP intraocular lens(IOL)implantation.METHODS: A prospective observational study. Forty-five patients with cataract phacoemulsification combined with IOL implantation were collected in our hospital from may 2018 to August 2019 were collected. According to whether trifocal intraocular lens(AT LISA tri 839MP)was implanted in both eyes, it was divided into two groups. For bilateral group(24 people), patients accepted AT LISA tri 839MP IOL in both eyes. For unilateral group(21 people), patients accepted AT LISA tri 839MP IOL in one eye and an aspheric monofocal IOL in the other eye. After follow-up 3mo, the binocular uncorrected distant, intermediate and near visual acuity(bUCDVA, bUCIVA, bUCNVA), visual function questionnaire, daily life degroscopy rate and satisfaction degree of the two groups were compared and analyzed. RESULTS: Three months after operation, there was no significant difference in bUCDVA, bUCIVA, bUCNVA between two groups(P>0.05). And also, there were no significant difference in VF-14-CN questionnaire score(96.2±0.50, 92.43±1.32), degroscopy rate(96%, 90%)and satisfaction(96%, 95%)between the two groups(P>0.05).CONCLUSION: Patients who accepted AT LISA tri 839MP IOL in both eyes and who accepted AT LISA tri 839MP IOL in one eye and an aspheric monofocal IOL in the other eye, share excellent bUCDVA, bUCIVA, bUCNVA. There was no significant difference in postoperative vision-related QoL, spectacle independency and satisfaction between the two groups. For patients who are not suitable for the implantation of trifocal IOL at one eye or who have had the aspheric single-focus IOL implanted at the previous eye, trifocal IOL implantation at another eye can be considered to meet the requirements of the whole binocular vision.
