“… 10 Best results appear to be achieved when the lowest add, or lens most resembling a monofocal IOL, is implanted in the dominant eye with the higher add lens in the non-dominant eye. 11 , 12 Previous studies have reported on the combination of the low-add (+2.75 D at the IOL plane) and moderate add (+3.25 D at the IOL plane) diffractive IOLs mentioned above. Results showed the combination provided a broader range of vision for patients.…”

Purpose To evaluate the vision, defocus curve, reading speed and patient satisfaction after implantation of an extended depth of focus (EDOF) IOL in one eye and a diffractive multifocal in the fellow eye. Setting One clinical practice in the USA. Design Prospective unmasked non-randomized clinical trial. Methods Subjects presenting for routine cataract surgery interested in reducing their dependence on spectacles were enrolled. Study endpoints included uncorrected and distance-corrected binocular distance (4 m), intermediate (66 cm) and near (40 cm) visual acuity at 3 months. Additional endpoints included the residual refraction, spectacle independence, overall satisfaction with vision, visual symptoms, reading speed and defocus curve. Results With a best distance correction, 77% (30/39) of subjects had 20/25 or better VA at distance, intermediate and near and nearly all subjects had 20/32 or better VA at all three distances. Defocus curve results showed mean continuous vision of 20/25 or better from plano to −2.50 D. Nearly 80% (31/39) of subjects had 20/25 visual acuity from 0.00 D to −2.50 D. The critical print size was between 0.3 and 0.4 logMAR (20/40 to 20/50 Snellen Equivalent). Spectacle independence was 100% at distance, 95% at intermediate and approximately 70% at near. The percentage of subjects who were “not at all” or “slightly” bothered by visual disturbances ranged from 64% (16/25) for Halos to 88% (22/25) for Starbursts. Conclusions EDOF/bifocal IOL blended implantation results in at least 20/25 mean visual acuity from distance to near with good spectacle independence and low reports of severe visual disturbances.

“…[10][11][12] Nevertheless, despite the continuous evolution of those implants, patients might present visual disphotopsia which may be a cause of discomfort, such as halos, glare, starburst, reduced contrast sensitivity and unsatisfactory uncorrected distance visual acuity (UDVA); accordingly, accurate patient election must be taken to accomplish acceptable postoperative outcomes. [13][14][15][16][17] The Acrysof IQ PanOptix ® IOL (Alcon Laboratories, Inc., Fort Worth, TX, USA) has a unique quadrafocal IOL design; however, in terms of function, it acts as a trifocal intraocular lens. It is a single-piece hydrophobic acrylic IOL and has a diffractive kinoform profile.…”

“…11,15,16,[18][19][20][21] This technology is called Enlighten ® Optical Technology by the manufacturer (Alcon Laboratories, Inc.) and there has been a great acceptance and patient satisfaction with this intraocular lens as the intermediate vision is very comfortable and sharp. 11,15,16,[19][20][21][22][23][24][25][26][27][28][29][30] The diffractive zone is also in the central portion and occupies 4.5 mm of the optical zone. It adds a negative spherical aberration of −0.1 μm on the anterior face of the lens to compensate the positive spherical aberration generated by the average human cornea.…”

The aim of this study was to compare the visual outcomes and subjective visual quality between bilateral implantation of an extended depth of focus intraocular lens, J&J Vision Tecnis Symfony ® ZXR00 (Group A) and bilateral implantation of a diffractive trifocal intraocular lens, Alcon Acrysof IQ PanOptix ® TNFT00 (Group B). Methods: This prospective, nonrandomized, comparative study of consecutive cases assessed 52 eyes of 26 patients operated on by the same surgeon (WTH) and binocularly implanted with multifocal intraocular lenses between May 2016 and July 2018. Binocular visual acuity for far, intermediate and near was tested in all cases. Ophthalmological evaluation included the measurement of binocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected near visual acuity (UNVA) at 40 cm, uncorrected intermediate visual acuity (UIVA) at 70 cm, monocular visual defocus curve and the quality of life (QoL) questionnaire, National Eye Institute Visual Functioning Questionnaire-25 (NEI-VFQ 25). Results: Postoperative UDVA was 0.00 and 0.09 logMAR (P<0.001), UIVA was 0.20 and 0.39 logMAR (P<0.001) and UNVA was 0.16 and −0.01 logMAR (P<0.001) in groups A and B, respectively; postoperative CDVA was −0.05 and 0.06 logMAR (P<0.001) in groups A and B, respectively. Conclusion: Both groups reported good subjective quality of vision regarding long, intermediate and short distances. Group A had a better performance for binocular UDVA, UIVA at 70 cm and CDVA, while regarding the monocular defocus curve, Group A outperformed Group B for long distances. Furthermore, Group B surpassed it in the short to very short distances, between the range of ≥2.00 D to 5.00 D of vergence. While Group A had a better performance regarding the vergences between 0.00 and 1.00 D (P<0.05) and at the vergence of +2.50 D (P=0.007). Group B outran Group A for UNVA at 40 cm.

“…Outcomes after implantation of the nontoric low-add lens in one eye and the higher-add lens in the other eye have successfully increased the range of vision compared to bilateral implantation of one or the other model. [12][13][14][15] In the blended bifocal studies, the average binocular uncorrected VA was −0.02 14 to 0.1 15 logMAR at distance, −0.02 14 to 0.22 12 logMAR at 60 cm and 0.07 12 to 0.5 14 logMAR at near. The binocular defocus curves with best distance correction have shown good distance VA (around 0.0 logMAR), intermediate and near VA (around 0.1 logMAR).…”

“…The binocular defocus curves with best distance correction have shown good distance VA (around 0.0 logMAR), intermediate and near VA (around 0.1 logMAR). [12][13][14][15] Using a validated quality of vision test, 90% of those implanted with the blended bifocal IOLs rated visual disturbances as not bothersome. 13 The objective of the current study was to provide a normative standard for refractive and visual outcomes and normative data related to quality of vision in eyes with significant corneal astigmatism undergoing cataract surgery with blended implantation of apodized diffractive toric IOLs.…”

Purpose: To review refractive, visual acuity, defocus curve and subjective visual quality results after bilateral implantation of an apodized diffractive toric intraocular lens (IOL) with a moderate add in the dominant eye and a higher add in the non-dominant eye. Setting: One site in Gainesville, GA, USA. Design: Single arm, non-randomized prospective study. Methods: This was a single-arm prospective study of visual acuity and subjective visual quality after implantation of a toric low-add apodized diffractive multifocal IOL in the dominant eye and a higher add IOL of the same type in the non-dominant eye three months after surgery. Binocular visual acuity at 4 m, 60 cm and 40 cm was tested. Other tests included refraction, defocus curve measurement and evaluation of the quality of vision. Toric IOL orientation was also measured. Results: A total of 29 subjects were enrolled. There were no statistically significant differences in the mean keratometry, corneal astigmatism or IOL sphere power implanted in the dominant and non-dominant eyes. Vision was preferred without any correction in more than half of the eyes tested (32/58, 55%). The residual refractive astigmatism was ≤ 0.50 D in 100% of eyes. Seventy-five percent of subjects (22/29) had 0.10 logMAR (20/25 Snellen) binocular uncorrected visual acuity at all tested distances. Glare and haloes were the most common visual disturbances, but most subjects (22/29, 76%) reported that they were not bothered by any visual disturbances. In 97% of eyes (56/58), the measured difference in orientation between 1 month and 3 months was less than 5 degrees, with no change more than 14 degrees. Conclusion: This blended bifocal IOL modality appears to be well-tolerated by subjects with a good range of vision and minimal bother from visual disturbances.
