Objective: To compare visual function and patient satisfaction in patients with bilateral diffractive multifocal intraocular lenses (IOL) and patients with monofocal IOL monovision.
Methods: Prospective nonrandomized controlled study. This study comprised consecutive bilateral cataract patients 45 cases (90eyes) between January 2011 and March 2012. All cases were divided into two groups: multifocal IOL group (23 patients) having implantation of AcrySof ReSTOR +3D(SN6AD1) multifocal IOL, monovision group (22 patients) having implantation of AcrySof IQ (SN60WF) IOL. Parameters analyzed 3 months postoperatively included binocular uncorrected distance, intermediate, and near visual acuities; stereo vision;photopic and mesopic contrast sensitivity function without glare. Parameters analyzed 6 months postoperatively included spectacle independence; subjective visual symptoms; and patient satisfaction. The independent-samples t test were used to compare the measure data which met normal distribution. The chi-square test was applied to compare categorical variables.
Results: There were no significant differences between groups in bilateral uncorrected distance vision (0.13 ± 0.06, 0.17 ± 0.19; Z = 1.755, P = 0.086) , intermediate (0.34 ± 0.05,0.33 ± 0.06; Z = -0.821, P = 0.416) , and near vision (0.35 ± 0.06, 0.41 ± 0.09; Z = 2.117, P = 0.051) . There were significant differences between groups in stereo vision (Median: 150″, 525″; Z = -2.092, P = 0.036) . Percentage of patients wearing spectacle were less than 10% in all groups [91.3% (21/23), 90.9% (20/22) ].On the questionnaire, patients in multifocal IOL group complained with double vision, trouble in night vision and halo(21.7%).
Conclusions: Pseudophakic monovision and MIOL achieved distance vision, intermediate vision and near vision. But monovision was no risk for disturbing visual symptoms associated with multifocal IOL.

Purpose: To evaluate the predictive value of the preoperative orientation and offset of angle alpha(chord alpha) and angle kappa(chord mu) for visual outcomes in patients who underwent trifocal intraocular lens (IOL) implantation.
Methods: Patient records of eyes that underwent AT LISA tri 839MP implantation were retrospectively collected and grouped according to the preoperative offset and orientations of chord alpha and chord mu. The two-dimensional location of each angle was described by the interaction of the orientation and offset.

Purpose: To assess differences in intraocular lens (IOL) power calculation prediction error (PE) considering the manufacturing tolerance or exact power (EP) versus labeled power (LP), and to compare accuracy using the Barrett formula with optimized constant versus a thick-lens formula.
Methods: The PE and absolute PE were calculated for a random eye of patients implanted with the multifocal Liberty Q-Flex 640PM IOL (Medicontur Ltd) considering the LP and the EP provided by the manufacturer. The outcomes for the Barrett with optimized constant formula and a thick-lens formula personalized for the surgeon, biometer, and IOL were compared.

Intraocular repair for subluxation of a multifocal intraocular lens (MFIOL) can be challenging, especially in toric models. Herein, we report a case of a 43-year-old man with a subluxated toric-type single-piece trifocal intraocular lens (IOL) with a C-loop that was spared using suture repositioning. Pars plana suturing was performed using the haptic externalization technique, and the tram-track suture technique was employed to flatten the tilted toric MFIOL.

Phacoemulsification with intraocular lens (IOL) implantation has become the standard method for cataract extraction regardless of its etiology. In modern phaco surgery, implantation of multifocal IOLs is considered the most advanced method for correcting aphakia following lens extraction. The wide range of available multifocal IOLs is promoting the ongoing discussion regarding the advantages of each type, as well as potential strategies for optimizing surgical outcomes.
