Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Multifocal intraocular lenses were introduced in the 1980s and have the benefit of promoting near and far vision simultaneous. However, these multifocal lenses have the disadvantages, including lower contrast sensitivity(CS) and visual discomfort, such as halos, glares and starburst, et al. Therefore, careful patient selection is crucial to achieve good postoperative results. The purpose of this study was to compare the visual outcomes and subjective visual quality between bifocal intraocular Lens(ReSTOR +2.5/+ 3.0D and Diff-aay) and trifocal intraocular Lens(AT Lisa tri 839MP). This prospective, nonrandomized, consecutive, comparative study included the assessment of 60 patients implanted with multifocal intraocular lens. visual acuity was tested in all cases. Ophthalmological evaluation included the measurement of uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA), and uncorrected intermediate visual acuity (UIVA), the analysis of contrast sensitivity (CS), visual defocus curve, spectacle independence, patient satisfaction, residual sphere, spherical equivalent (SE), cylinder and complications.
