Detailed Description
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.

Outcome Measures
Primary Outcome Measures
- Uncorrected distance visual acuity [3 months after surgery]
Uncorrected distance visual acuity (4m) were measured using the reading table model of the Early Treatment Diabetic Retinopathy Study charts (ETDRS; Vector Vision, Ltd, Greenville, OH, USA).
- Uncorrected near visual acuity [3 months after surgery]
Uncorrected near visual acuity (40cm) were measured using the reading table model of the Early Treatment Diabetic Retinopathy Study charts (ETDRS; Vector Vision, Ltd, Greenville, OH, USA).
- Uncorrected intermediate visual acuity [3 months after surgery]
Uncorrected intermediate visual acuity (60cm) were measured using the reading table model of the Early Treatment Diabetic Retinopathy Study charts (ETDRS; Vector Vision, Ltd, Greenville, OH, USA).
Other Outcome Measures
- Quality of vision [3 months after surgery]
Quality of vision was measured using the National Eye Institute Visual Function Questionnaire (NEI VFQ)-25. The NEI-VFQ was developed at the RAND under the sponsorship of the NEI; it provides a self-reported measure of visual function.
