Since position and centration have shown to affect the effectiveness of multifocal intraocular lenses (MFIOLs), some authors have proposed using the "coaxially sighted IOL light reflex" as a landmark to allow consistent centration of MFIOLs. Postoperatively, assessing the location of the intraocular lens with respect to the visual axis is also important. Centration of the MFIOLs can be identified postoperatively by slit lamp biomicroscopy, but it is still a qualitative method. The Nidek OPD Scan III is used. The instrument obtains retro illumination images, which allows the observation of the diffractive rings of the multifocal intraocular lenses implanted following phacoemulsification. The retro illumination image describes the location of the visual axis (white cross with blue borders +), the center of the photopic (pink cross) and mesopic (turquoise cross) pupil, quantifies the distance between the center of the pupil and the visual axis, and places the visual axis in degrees. It is attempted to match the rings of the lens with that of the acetate grid. Once the best possible equidistance between the lens and grid rings has been achieved. This method can be useful to be able to have reference of a real value of decentration of the lenses and thus have a surgical plan and try to center the lenses. We are also creating a technique to properly center the lenses, in addition to performing an analysis of the results in terms of postoperative visual quality in relation to the lens's decentration and thus see how this really affects.

Objective To evaluate and compare the objective and subjective outcomes after the bilateral implantation of a diffractive bifocal and trifocal intraocular lens. Methods This is a case–control, single-center observational study which included 27 patients; 16 patients were implanted bilaterally with the bifocal AcrySof IQ ReSTOR+3.0D and 11 patients with the trifocal AT LISA tri 839MP. Uncorrected visual acuity at distance, intermediate, and near under mesopic and photopic conditions using ETDRS charts with 10% and 100% contrast, corrected distance visual acuity, and binocular defocus curve in photopic conditions; binocular contrast sensitivity under mesopic and photopic conditions for far and near distances were assessed. The Visual Function Questionnaire-25 questionnaire was used to assess patients' satisfaction. All the measurements were performed 6–24 months after cataract surgery. Results The ReSTOR group had better binocular uncorrected near visual acuity in photopic conditions with low and high contrast charts ( p = 0.040 and p = 0.033, respectively), as well as in far contrast sensitivity measurement under mesopic conditions with a spatial frequency of 3 cycles per degree ( p = 0.034). There was not a significant difference between the two study groups in uncorrected near, intermediate or distance vision under mesopic conditions. The AT LISA tri study group had better subjective outcomes. Conclusion Both intraocular lenses restore visual acuity after cataract surgery. The ReSTOR intraocular lens provides better objective outcomes than the AT LISA tri, although the latter provides better subjective outcomes. The relevance of this study is the evaluation of both objective and subjective outcomes.

AbstractThis meta-analysis aimed to evaluate the clinical outcomes following implantation of trifocal intraocular lenses (IOLs) or a hybrid multifocal-extended depth of focus (EDOF) IOL in cataract or refractive lens exchange surgeries. We examined 13 comparative studies with bilateral implantation of trifocal (898 eyes) or hybrid multifocal-EDOF (624 eyes) IOLs published through 1 March 2020. Better uncorrected and corrected near visual acuity (VA) were observed in the trifocal group (MD: − 0.143, 95% CI: − 0.192 to − 0.010, P < 0.001 and MD: − 0.149, 95% CI: − 0.217 to − 0.082, P < 0.001, respectively), while the hybrid multifocal-EDOF group presented better uncorrected intermediate VA (MD: 0.055, 95% CI: 0.016 to 0.093, P = 0.005). Trifocal IOLs were more likely to achieve spectacle independence at near distance (RR: 1.103, 95% CI: 1.036 to 1.152, P = 0.002). The halo photic effect was generated more frequently by the trifocal IOLs (RR: 1.318, 95% CI: 1.025 to 1.696, P = 0.031). Contrast sensitivity and subjective visual quality yielded comparable results between groups. Trifocal IOLs demonstrated better performance at near distance but apparently led to more photic disturbances. Our findings provided the most up-to-date and comprehensive evidence by comparing the benefits of advanced IOLs in clinical practice.

Objective. To evaluate the postoperative visual quality of cataract patients with extreme myopia after implantation of aspheric intraocular lenses (IOLs). Methods. Thirty-three eyes were enrolled in this prospectivestudy. Eighteen eyes with an axial length longer than 28 mm were included in the extreme myopia group, and the other 15 eyes were included in the nonextreme myopia group. Phacoemulsification and aspheric IOL implantation were performed. Six months after cataract surgery, best-corrected visual acuity (BCVA), contrast sensitivity, and wavefront aberrations were measured, and subjective visual quality was assessed. Results. The BCVA improved significantly after surgery for both groups, and patients in the nonextreme myopia group achieved better postoperative BCVA due to better retinal status of the eyes. The evaluation of contrast sensitivity without glare was the same in both groups, whereas patients in the nonextreme myopia group performed better at intermediate spatial frequencies under glare conditions. The two groups did not show a significant difference in high-order aberrations. With regard to subjective visual quality, the composite scores of both groups did not differ significantly. Conclusions. Aspheric IOLs provided good visual outcomes in cataract patients with extreme myopia. These patients should undergo careful evaluation to determine the maculopathy severity level before surgery.

AbstractThe accuracy of intraocular lens (IOL) calculations is suboptimal for long or short eyes, which results in a low visual quality after multifocal IOL implantation. The purpose of the present study is to evaluate the accuracy of IOL formulas (Barrett Universal II, SRK/T, Holladay 1, Hoffer Q, and Haigis) for the Acrysof IQ Panoptix TFNT IOL (Alcon Laboratories, Inc, Fort Worth, Texas, United States) implantation based on the axial length (AXL) from a large cohort of 2018 cases and identify the factors that are associated with a high mean absolute error (MAE). The Barrett Universal II showed the lowest MAE in the normal AXL group (0.30 ± 0.23), whereas the Holladay 1 and Hoffer Q showed the lowest MAE in the short AXL group (0.32 ± 0.22 D and 0.32 ± 0.21 D, respectively). The Haigis showed the lowest MAE in the long AXL group (0.24 ± 0.19 D). The Barrett Universal II did not perform well in short AXL eyes with higher astigmatism (P = 0.013), wider white-to-white (WTW; P < 0.001), and shorter AXL (P = 0.016). Study results suggest that the Barrett Universal II performed best for the TFNT IOL in the overall study population, except for the eyes with short AXL, particularly when the eyes had higher astigmatism, wider WTW, and shorter AXL.

Drops of lens nucleus/cortex particles into the vitreous cavity or dislocations of intraocular lenses (IOLs) are one of the serious complications of cataract surgery with an increasing relative frequency with the increase in the number of cataract surgeries. In addition, spontaneous and traumatic dislocations are other common case groups that should be treated. In this article, the vitreous dislocations of nucleus/cortex residues or IOL dislocations are discussed with different vitreoretinal surgical techniques.
