“…9,21 Our study suggests that there may be an additional role of misalignment between the visual and pupillary axis in the occurrence of photic phenomenon after multifocal IOL implantation. Further studies will be required to analyze the effect of the same on induced higher order aberrations, and contrast sensitivity after multifocal IOL implantation.…”

“…Walcow and Klemen had findings similar to that seen by us with UCVA in a questionnaire-based study on a diffractive IOL, however, they found cylindrical power to be an additionally important independent predictor of dissatisfaction. 21 The reason for this difference can be in our exclusion of high cylinders from the preoperative data and the low postoperative cylinders. We agree that high cylinders and induced higher order aberration (acquired aberropia) may have an impact on the final satisfaction of the patients.…”

“…[7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] Causes associated with photic phenomena noted in previous studies have included IOL decentration, retained lens fragment, posterior capsular opacification, dry-eye syndrome, uncorrected visual acuity (UCVA), use of spectacles for distance purposes, postoperative astigmatism, and postoperative spherical equivalent. 9,21 However, none of the studies in published literature have evaluated the role of misalignment between the visual axis and the pupillary axis, or the angle kappa, as a specific predictor for patient symptoms. The current study evaluates the visual acuity and quality-related satisfaction of patients implanted with a multifocal IOL, and evaluates the factors predicting it including angle kappa.…”

Purpose To evaluate the visual acuity and quality-related satisfaction of patients implanted with a refractive design multifocal intraocular lens (IOL), and evaluate the factors predicting it including angle kappa. Setting Dr Agarwal's Eye Hospital and Eye Research Centre, Chennai. Methods In this prospective trial, 50 eyes of 44 consecutive patients were included. All patients underwent phacoemulsification with multifocal IOL implantation (Rezoom IOL, Abbott Medical Optics). The preoperative and postoperative assessment included slit lamp biomicroscopy, uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA) and kappa angle assessment. At 1 year, 37 patients (43 eyes), who finished follow-up, were asked to rate their symptoms on a graded questionnaire (0-5 for five queries). Results The decimal scores for UCVA and BCVA were 0.38 ± 0.21 and 0.47 ± 0.17 (preoperative), and 0.75 ± 0.22 and 0.99 ± 0.11 (postoperative), respectively. Symptom scores were haloes 0.98 ± 1.7, glare 0.69 ± 1.48, blurred distance 1.0 ± 1.7, intermediate 1.34 ± 1.6, near 1.06±1.8. On regression analysis haloes depended on angle kappa and distance UCVA (R 2 ¼ 0.26, P ¼ 0.029), and glare on angle kappa (R 2 ¼ 0.26, P ¼ 0.033). Poor satisfactions with distance, intermediate, and near vision were linked with distance UCVA (R 2 ¼ 0.17, P ¼ 2.3 Â 10 À4 ), distance UCVA (R 2 ¼ 0.1, P ¼ 0.04), and near UCVA (R 2 ¼ 0.12, P ¼ 0.03), respectively. The strongest predictor, however, for overall visual discomfort was distance UCVA (R 2 ¼ 0.1, P ¼ 0.04).Conclusions Our study suggests that there may be a role of misalignment between the visual and pupillary axis (angle kappa) in the occurrence of photic phenomenon after refractive multifocal IOL implantation.

“…[1][2][3][4][5][6] The use of multifocal IOLs offers a significant opportunity to improve distance and near vision. However, these improved IOL designs are insufficient if the lens does not suit the lifestyle of patients recovering their vision at all distances, including intermediate distance.…”

he implantation of a multifocal intraocular lens (IOL) after the extraction of cataract has been reported as an alternative to improve the near vision performance and the quality of life of some patients. [1][2][3][4][5][6] The use of multifocal IOLs offers a significant opportunity to improve distance and near vision. However, these improved IOL designs are insufficient if the lens does not suit the lifestyle of patients recovering their vision at all distances, including intermediate distance.4-8 Many IOL technologies are commercially available for implantation after cataract surgery and several studies have reported that diffractive multifocal IOLs with an aspheric profile perform better than refractive multifocal or accommodating IOLs in terms of near visual acuity. On the other hand, aspheric profiles give better optical quality in comparison to spherical profiles. [8][9][10][11][12][13] Recently, a new multifocal model IOL has been introduced in clinical practice combining two diffractive apodized profiles that can provide three foci for distance, near, and intermediate vision.14 There are few publications describing the outcomes after the implantation of a trifocal intraocular lens and some of these have limited samples. [15][16][17] Additionally, this new IOL offers the possibility to be implanted through a sub-2-mm incision, accomplishing the advantages of microincisional cataract surgery (MICS).The aim of the current study was to evaluate the visual and the intraocular performance of this new trifocal IOL in eyes implanted following cataract surgery performed through MICS. PATIENTS AND METHODS PatientsIn this prospective, consecutive, non-comparative interventional study, we included 40 eyes of 20 patients with T ABSTRACT PURPOSE: To evaluate the visual outcomes of patients with a new diffractive trifocal intraocular lens (IOL). METHODS:A trifocal diffractive Fine Vision IOL (Physiol, Liege, Belgium) was implanted after microincision cataract surgery (MICS) in 40 eyes of 20 patients with bilateral cataract. The monocular and binocular visual performance and the refractive status were assessed, as well as the defocus curve and contrast sensitivity at 1 and 6 months postoperatively. RESULTS:The monocular visual outcomes (logMAR) at 6 months postoperatively were uncorrected distance visual acuity 0.18 ± 0.13, uncorrected near visual acuity 0.26 ± 0.15, and uncorrected intermediate visual acuity 0.20 ± 0.11. With the best distance correction, the visual outcomes were 0.05 ± 0.06 for corrected distance visual acuity, 0.16 ± 0.13 for distance corrected near visual acuity, and 0.17 ± 0.09 for distance corrected intermediate visual acuity. Binocular defocus curve at 6 months shows a wide range of useful vision with 0.19 ± 0.08 (logMAR) at -1.50 diopter defocus. The monocular contrast sensitivity under scotopic conditions (3 cd/m 2 ) was within normal range for a population older than 60 years. CONCLUSION:The trifocal Fine Vision IOL can restore vision at different distances after cataract surgery, specifically...
