Purpose: To analyze patient satisfaction and difficulties with bilateral multifocal intraocular lenses (IOLs) implantation and aspheric monofocal IOLs implantation using monovision, after cataract surgery.
Materials and methods: A total of 61 participants were included in the study, 29 with monovision and 32 with multifocal lenses. The inclusion criteria were patients undergoing phacoemulsification for bilateral visual impairment due to cataracts and presenting with postoperative visual acuity of 20/30 or better for distance and line J3 or better for near vision.
Results: The 2 groups had similar results regarding difficulties with daily activities such as distance vision, near vision, watching television, reading, cooking, using a computer or cellphone, shaving/putting on makeup and shopping. There were differences in responses between the groups regarding difficulty with night vision (P=0.0565) and night driving (P=0.0291). Degree of satisfaction in terms of distance vision without glasses was statistically significantly better in monovision group (P=0.0332), but not for near (P=0.9101).
Conclusion: Both techniques yielded satisfactory results regarding visual acuity for different activities without the need to use glasses. Multifocal lenses are a good option for patients with the exception of night driving, and who desire independence from glasses.
