Brief summary
The investigators are going to Investigate the comparative efficacy of the patients who underwent cataract surgery with three different multifocal IOLs.
Detailed description
Going to analyze the clinical results of 60 patients who underwent bilateral cataract surgery and multifocal IOL implantation. The patients were divided into the following three groups: Mix-and-Match, EDOF, and Trifocal. The clinical assessments included uncorrected near, intermediate, distance and best corrected distance visual acuity, defocus curves, contrast sensitivity, and reading speed. Patient satisfaction was evaluated by questionnaire. All outcomes were compared among the three groups.
Interventions
DEVICETrifocal
Phacoemulsification and implantation of FineVision PodFT IOLs (PhysIOL SA) in both eyes.
DEVICEMix-and-Match
Phacoemulsification and implantation of Tecnis ZKB00 multifocal IOL with +2.75 D add power (Abbott Medical Optic Inc., Santa Ana, CA) in the dominant eye, and a Tecnis ZLB00 multifocal IOL with +3.25 D add power (Abbott Medical Optics Inc.) in the non-dominant eye.
DEVICEEDOF
Phacoemulsification and implantation of Tecnis Symfony ZXR00 trifocal IOLs (Abbot Medical Optics Inc.) in both eyes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative uncorrected near, intermediate, and far visual acuity. | At 1month and 3months after surgery | logMAR |
| Postoperative contrast sensitivity in the three groups. | Postoperative 3 months | 3, 6, 12, and 18 cycles per degree using a CSV-1000 chart (Vector Vision, reenville, OH) under photopic (85 cd/m2), mesopic (\ 3 cd/m2), and mesopic with glare conditions |
| Postoperative satisfaction questionnaire. | Postoperative 3 months | patients were shown images and asked to rate the frequency, degree, and discomfort related to the visual artifacts as none, minimal, moderate, or severe (0, 1, 2, or 3 points for the respective levels). The mean score was calculated. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative refractive outcome | Postoperative 3 months | Diopter |
