Purpose
The Tecnis Odyssey is a diffractive presbyopia-correcting IOL. Limited data exists on its outcomes in post-refractive and non-post-refractive patients in clinical practice. Our clinic has a high degree of patients interested in spectacle independence, so we have set out to perform a review of outcomes in patients utilizing this new lens technology.
Methods
This retrospective case series will examine patients who received the Tecnis Odyssey lens at a single center, with a minimum follow-up period of one month post-operatively (POM1). Patient and lens selection will be determined by the treating surgeon. The analysis will include pre- and post-operative measures such as spherical equivalent (SE), uncorrected distance visual acuity (UCDVA), uncorrected near visual acuity (UCNVA), history of refractive surgery, and pre-existing retinal conditions (e.g., epiretinal membrane, retinal detachment repair, age-related macular degeneration).
Results
289 patients met criteria: 49 were status-post LASIK/PRK. The average spherical equivalent at pre-op/POM1 for post-myopic LASIK/PRK was -0.691/-0.273 (UCDVA Pre 20/50; UCDVA POM1 20/25,UCNVA POM1 J1); for non-refractive patients ??-2.49/-0.072 (20/80; 20/23, J1). There was a statistically significant difference between these groups for distance (p=0.008, alpha=0.05), but there was not at near (p=0.418, alpha 0.05). Overall, 80.6% were happy with their vision at POM1; near vision was the most cited reason for dissatisfaction (59.5%), followed by haloes (9.8%).
Conclusion
Refractive outcomes for the Tecnis Odyssey lens were excellent. Most patients have been pleased with postoperative results, though some were dissatisfied with near vision. While there is a statistical difference between post-refractive and non-refractive patients' distance visual outcomes, there was no clinical difference between the groups.

Purpose
To evaluate the postoperative visual performance of patients after bilateral implantation of the Zeiss AT ELANA 841P lens, a new hydrophobic trifocal intraocular lens (IOL).
Methods
This ongoing prospective clinical study includes a total of 29 patients scheduled for bilateral implantation of the AT ELANA 841P (Carl Zeiss Meditec AG, Jena, Germany) IOL following cataract or refractive lens exchange surgery. Follow-up visits are scheduled for 1-month, 3-months, and 12-months and include monocular and binocular uncorrected and distance-corrected visual acuities (VA) for far (UDVA, CDVA), intermediate (UIVA, DCIVA), and near (UNVA, DCNVA), subjective refraction, defocus curve, photopic and mesopic contrast sensitivity, patient satisfaction in terms of visual disturbance and spectacle independence, and the evaluation of posterior capsule opacification.
Results
To date, 7 patients with a mean age of 62 � 6 years have been enrolled in the study. At 1 month postoperative, binocular visual acuity exhibited UDVA/CDVA of -0.09/-0.16, UIVA/CIVA (80 cm) of 0.04/0.01, UIVA/CIVA (66 cm) of 0.03/0.02 and UNVA/CNVA (40 cm) of -0.01/-0.04 in logMAR units. Further detailed evaluations are ongoing.
Conclusion
Our initial results indicate that the AT ELANA allows full range of uncorrected vision over a wide range of distances and is a safe, predictable, and effective treatment option in the course of cataract or refractive lens exchange surgery. Further results regarding spectacle independence, photic phenomena and contrast sensitivity are pending.

Purpose
This study evaluates the perception of visual quality and dysphotopsias through various types of intraocular lenses as viewed through a simulator. The results are analyzed according to patient age, gender, and eye dominance. The primary goal of this study is to improve prediction of patient satisfaction with premium lens technology.
Methods
The SimVis Gekko (2 EyesVision, Madrid, Spain) headset is a novel way to quantitate perception of vision with various lenses prior to cataract surgery. Sixty healthy volunteers (aged 15-70) with clear lenses or mild cataracts (BCVA of 20/40 or better) will be enrolled. Patients will be asked to look at the Snellen visual acuity chart and they will also be shown a series of nighttime glare images (at 20 feet) and asked to rate the quality of their vision and severity of dysphotopsias in each scenario: Scenario 1-bilateral monofocal lenses, Scenario 2-bilateral extended depth of focus (EDOF) lenses and Scenario 3- bilateral multifocal (MF) lenses.
Results
23 patients have completed testing (26% male, 74% female). Thus far, there is an correlation between gender and visual satisfaction with males ranking image quality better than females with all scenarios (3.11 versus 2.46, T value =1.2, p>0.05). In scenario 1 (bilateral monofocal) there was an insignificant correlation between satisfaction and Snellen acuity (R=-0.3352). In scenario 2 (bilateral EDOF) there was a positive correlation (R=0.1819) and in scenario 3 (bilateral MF), there was an inverse correlation with satisfaction (R=-0.1207). In scenario 3, there is a trend toward increased dysphotopsia ratings in younger patients (less than age 30). Data analysis is ongoing.
Conclusion
Quality of vision and perception of dysphotopsias associated with premium lenses may be correlated with patient age, gender and eye dominance. The lack of direct correlation between Snellen acuity and visual satisfaction indicates that Snellen acuity does not fully reflect overall satisfaction with vision.

Purpose
To compare the visual function of continuous-focus IOLs, Synergy (DFR) and Oddysey (DRT).
Methods
A model eye with 24.0 mm axial length, 7.4 mm corneal curvature, and 0.20 ?m 4th order spherical aberration was used. Pupil diameters of 2, 3, and 4 mm were set. 20.0D DFR and DRT were inserted and the visual acuity chart was photographed from a distance of 63 cm, corrected to infinity in the distance, from which the chart was photographed in 0.25D increments from +2D to -4D.
Results
Focal peaks were observed at 0D and -3D, +0.5D and -2.0D for ?3mm, 0D and -2.75D for ?4mm, and 0D and -2.75D, 0D and -2.0D for ?2mm (DFR, DRT order). DRT was better at ?4mm, and DFR was better at ?2mm. The range of logMAR 0.1 or less in far visual acuity was 0.3D and 0.75D at ?3mm, 0.4D and 0.5D at ?4mm, and 0.6D and 1.1D at ?2mm.
Conclusion
DFR had better near visual acuity; DRT had a more farsighted distance visual acuity peak with increasing pupil diameter. In addition, the distance visual acuity peak was slightly wider for DRT.

Purpose
The ARTIS Symbiose intraocular lens (IOL) system (Cristalens Industrie, France) offers a multifocal approach: one lens enhances intermediate vision (ARTIS Symbiose MID), the other near vision (ARTIS Symbiose PLUS), both maintaining distance focus. This study compares visual acuity with ARTIS Symbiose to the AcrySof IQ PanOptix IOL (Alcon, USA).
Methods
Bilateral implantation of AcrySof IQ PanOptix or ARTIS Symbiose IOLs was randomly assigned to 100 eyes of 50 patients. Visual acuity at far, intermediate, and near distances, as well as defocus curve, were compared between ARTIS MID, ARTIS PLUS IOLs, and AcrySof IQ PanOptix IOL. Postoperative follow-up at 1, 6, and 12 months included assessment of uncorrected (UDVA) and corrected (CDVA) distance visual acuity, uncorrected (UIVA) and distance-corrected intermediate (DCIVA) visual acuity at 80 cm. Additionally, defocus curve testing with distance correction and monocular and binocular contrast sensitivity testing were conducted as part of the one-month follow-up visit.
Results
To date, 50 patients with a mean age of 70 � 8 years have been enrolled in the study. At 1 month postoperative, binocular visual acuity for ARTIS Symbiose IOL exhibited UDVA/CDVA of 0.02/-0.06 and UIVA/CIVA of 0.00/0.03 in logMAR. The AcrySof IQ PanOptix lens showed comparable results with UDVA/CDVA of -0.04/-0.10 and UIVA/CIVA of 0.01/0.02. At 1 month postoperative, the binocular distance-corrected defocus curve for the ARTIS Symbiose lens system exhibited continuous visual acuity of 0.10 logMAR or better within the range of +0.75 to -2.75 diopters of defocus. AcrySof IQ PanOptix demonstrated visual acuity of 0.10 logMAR or better within the range of +0.75.0 to -3.00 diopters of defocus.
Conclusion
Both the complementary diffractive lens system and conventional diffractive multifocal IOL show promising results in providing functional outcomes across distance, near, and intermediate vision. Additionally, the continuous improvement in binocular visual acuity highlights the efficacy of ARTIS Symbiose lens system.

Purpose
This study aims to evaluate the different management options for post-operative intolerance to presbyopia correcting intraocular lenses
Methods
Retrospective chart review of patients who were managed by Dr. Randleman for intolerance to presbyopia- correcting intraocular lenses at Cole Eye Institute. The primary outcomes are change in visual acuity, change in visual symptoms, and patient satisfaction.
Results
This study analyzed 109 eyes from 73 patients intolerant to presbyopia-correcting intraocular lenses (IOL). The most common IOLs were trifocal (54.6%) and extended depth of focus (EDOF) (30.6%). The average age was 66.3 years, with 41.1% males. The main complaints were blurry vision (74%) and photic phenomena (44.6%). Nearly half of the patients had multiple complaints. After treatment, 42.5% of patients reported symptom resolution. Laser vision correction (LVC) had the highest success rate (70%-80%), while IOL exchange improved symptoms in 57.1%-67%. All IOLs were exchanged to a monofocal IOL. Uncorrected visual acuity significantly improved after treatment (p=0.049).
Conclusion
In our patient group, the main cause of IOL intolerance was blurry vision, followed by photic phenomena. Multiple treatments were often needed, with laser vision correction showing the highest rate of resolution. Symptom improvement didn�t appear directly linked to changes in refractive parameters.

Purpose
To evaluate the mesopic monocular and binocular visual acuity outcomes following implantation of either a novel Full Range of VIsion (FRoV) enVista intraocular lens (IOL) or monofocal enVista IOL in US subjects undergoing cataract surgery.
Methods
This prospective, multicenter, randomized, controlled study included cataract subjects who underwent bilateral implantation of either enVista Envy FRoV IOL (study group, n=284) or enVista monofocal IOL (control group, n=142). Outcome measures included assessment of the monocular and binocular distance-corrected visual acuity at intermediate (DCIVA, 66 cm) and near (DCNVA, 40 cm) under mesopic conditions at postoperative 120�180 days.
Results
Postoperatively, the FRoV group showed significantly better mean mesopic DCIVA (monocular 0.29 � 0.14 vs 0.46 � 0.16 logMAR and binocular 0.21 � 0.12 vs 0.39 � 0.13 logMAR) compared to the monofocal group (both p<0.0001). similarly,="" the="" mesopic="" dcnva="" was="" also="" statistically="" significantly="" better="" in="" the="" frov="" group="" (monocular="" 0.35="" �="" 0.15="" logmar="" vs="" 0.66="" �="" 0.18="" logmar="" and="" binocular="" 0.26="" �="" 0.13="" logmar="" vs="" 0.59="" �="" 0.15="" logmar)="" compared="" to="" the="" monofocal="" group="" (both="" p="">0.0001).>< />
Conclusion
The Envy FRoV IOL showed good binocular mesopic DCIVA (20/32) and DCNVA (20/37), suggesting that the FRoV IOL had good efficacy even under mesopic conditions. While the Envy FRoV group demonstrated a mean binocular DCIVA of more than 2 lines better, the mean DCNVA was approximately 4 lines better than the monofocal group.

Purpose
To compare the visual performance and defocus curve of three trifocal intraocular lenses: Liberty (Medicontur), FineVision (PhysIOL) and AT Lisa Tri (Zeiss).
Methods
150 eyes of 75 patients were included in this prospective and observational study of which 25 patients were implanted bilaterally with the Liberty intraocular lens, 25 patients with FineVision and 25 patients with AT Lisa. Defocus curve (+3.00 to -5.00D) were obtained monoculary under photopic conditions at three months after surgery. The optotype used was ETDRS. Furthermore, postoperative refraction and visual acuity at distance, intermediate and near distances were measured both a month and three months. Paired t-test were used to assess differences in visual acuity.
Results
Three months after surgery, the Liberty group exhibited a mean corrected distance visual acuity (CDVA) of -0.03�0.08, corrected intermediate visual acuity (CIVA) of 0.25�0.17, and corrected near visual acuity (CNVA) of 0.09�0.19. The FineVision group showed a mean CDVA of 0.04�0.04, CIVA of 0.12�0.05, and CNVA of 0.09�0.05. The AT Lisa group had a mean CDVA of 0.05�0.05, CIVA of 0.19�0.03, and CNVA of 0.13�0.15. In the defocus curve, the Liberty group showed -0.03�0.08 at distance, 0.14�0.14 at intermediate, and 0.04�0.11D at near. FineVision recorded 0.01�0.03D, 0.31�0.08D, and 0.20�0.02D, and AT Lisa group 0.04�0.05D, 0.14�0.04D, and 0.15�0.04D, respectively.
Conclusion
All three lens groups had good refractive results. The Liberty group achieved the best visual acuity for distance and near vision, while Liberty and AT Lisa excelled in intermediate vision. The defocus curve showed that the Liberty lens offered the best visual performance across the full range. Overall, the Liberty lens was slightly superior.

Purpose
To evaluate the visual performance and to obtain the defocus curve following cataract surgery and implantation of a new trifocal diffractive intraocular lens (IOL).
Methods
A total of 25 patients were enrolled in this observational prospective study after implantation of the Acriva Trinova Pro IOL (VSY Biotechnology). Defocus curve (+3.00 to -5.00) was obtained monoculary under photopic conditions at three months after surgery and the optotype used was ETDRS. Furthermore, postoperative refraction and visual acuity at distance, intermediate and near distances were measured both a month and three months.
Results
One month and three months after surgery, the spherical equivalent was -0.05 � 0.32 D and -0.01 � 0.51 D respectively. Corrected distance visual acuity corrected distance visual acuity (CDVA) of 0.01�0.10 LogMAR, corrected intermediate visual acuity (CIVA) of 0.18�0.16 LogMAR, and corrected near visual acuity (CNVA) of 0.16�0.13 LogMAR after one month. After 3 months the CDVA was 0.04�0.23 LogMAR, CIVA of 0.19�0.13 LogMAR, and CNVA of 0.13�0.15 LogMAR. The results on the defocus curve at three months were in far distance -0.05 � 0.32 LogMAR, intermediate 0.19 � 0.12 LogMAR and near 0.20 � 0.23 LogMAR.
Conclusion
Patients implanted with the Acriva Trinova Pro IOL showed a significant improvement in visual acuity in different distances. The results obtained show that this lens is predictable.

Purpose
To compare uncorrected visual acuity and patient-reported near and distance vision outcomes using a validated near activity visual questionnaire (NAVQ) in patients undergoing cataract surgery with implantation of a small aperture intraocular lens (IOL) or a trifocal IOL in at least one eye.
Methods
This multicenter, retrospective chart review included real-world data of patients who had undergone implantation of PanOptix trifocal IOL (N = 37) or IC-8 Apthera IOL (N = 40) in at least one eye. In the IC-8 IOL group, 53% of patients had ocular comorbidities such as prior LASIK, PRK, RK, KCN, and EBMD, whereas in the PanOptix group, none (except one) had ocular comorbidities (LASIK). Outcome measures were monocular uncorrected visual acuities at distance (UDVA), intermediate (UIVA), and near (UNVA), with subjective evaluation of patient experience with near vision tasks using a validated NAVQ questionnaire.
Results
Postoperatively, mean UDVA was comparable between the IC-8 and PanOptix groups (0.04�0.10 vs 0.00�0.08 logMAR). Mean UIVA was also comparable between the IC-8 and PanOptix groups (0.02�0.06 vs 0.02�0.13 logMAR). Mean UNVA trended to be better in the PanOptix group than IC-8 (0.05�0.07 vs 0.11�0.17 logMAR). For most of the near-vision activities, the proportion of patients reporting �no or a little difficulty� was similar, with less than 5% difference between the two groups. The proportion of patients who were �completely to moderately satisfied� with overall vision and vision at night was better in the IC-8 group than PanOptix (95.0% vs 83.8%).
Conclusion
Despite a higher proportion (>50%) of IC-8 IOL patients having preexisting ocular comorbidities, IC-8 group showed comparable UDVA and UIVA to the PanOptix group. UNVA was better in the PanOptix group. Satisfaction with the overall vision and vision at night was higher in the IC-8 group compared to the PanOptix group.

Purpose
To compare the visual and refractive outcomes of a capsulotomy fixated versus in the bag multifocal toric IOLs
Methods
Prospective, interventional, randomized study with 50 patients in each group. Complete ocular examination conducted on postoperative day 1, 1 week,1 month and 3 months, assessing uncorrected and corrected distance and near vision (33 cm), intermediate visual acuity (60, 80 cm), contrast sensitivity (FACT), Defocus curves, postoperative refractive cylinder, rotational stability and overall patient satisfaction.
Results
The capsulotomy fixated IOL group showed significantly better UDVA at all postoperative visits (p<0.004). while="" both="" groups="" had="" comparable="" near="" vision,="" intermediate="" vision="" and="" defocus="" curves,="" capsulotomy="" fixated="" iol="" group="" demonstrated="" significantly="" better="" residual="" refraction="" (p-value:="" 0.019)="" and="" superior="" contrast="" sensitivity="" at="" higher="" spatial="" frequencies.="" rotational="" stability="" (mean="" rotation)="" in="" the="" capsulotomy="" fixated="" toric="" iol="" group="" was="" 2�="" �="" 1.73�="" as="" compared="" to="" 3.9�="" �="" 2.46�="" in="" capsular="" bag="" toric="" iol="" group="" at="" postop="" 3="" months.="" overall="" patient="" satisfaction="" scores="" were="" found="" to="" be="" higher="" in="" the="" capsulotomy="" fixated="" iol="" group="" in="" terms="" of="" night="">0.004).>
Conclusion
Both capsulotomy fixated IOLs and in-the-bag IOLs provided good distance, intermediate and near visual acuity. However, compared to the in-the-bag IOL group, the capsulotomy-fixated IOL group performed significantly better in terms of residual refraction, contrast sensitivity, rotational stability, and patient satisfaction.

Purpose
To evaluate the visual outcomes and stability of the Femtis Mplus IOL in a young patient with bilateral congenital posterior polar cataract and posterior capsule dehiscence
Methods
A 28 year old male patient with bilateral congenital posterior polar cataract and posterior capsule dehiscence underwent cataract surgery via phacoemulsification. A premium IOL, Femtis Mplus was implanted with anterior capsular fixation in both eyes, with a toric IOL in the left eye. Visual outcomes were assessed on postop days 1 and 15.
Results
On postoperative day 1, uncorrected visual acuity in both eyes was 6/6P, improving to 6/5 on day 15, with uncorrected near vision of N5. No IOL rotation was observed in the left eye at any visit. Intermediate vision at 60 cm and 80 cm was N5 on both post operative visits with good contrast sensitivity.
Conclusion
In young patients with posterior capsule dehiscence, anterior capsular fixated IOL gives excellent visual outcomes at all distances with great stability.

Purpose
This study aims to compare the postoperative clinical outcomes in patients who underwent phacoemulsification followed by implantation of one of three types of intraocular lenses: an extended depth of focus intraocular lens (AcrySof� Vivity), a trifocal intraocular lens (Tecnis� Synergy), or a trifocal intraocular lens (AcrySof� PanOptix).
Methods
A retrospective analysis was conducted on patients who received bilateral implantation of one of the following IOLs after phacoemulsification at Samsung Medical Center between February 2021 and August 2024: AcrySof� Vivity, Tecnis� Synergy, or AcrySof� PanOptix. Preoperative and postoperative assessments included refraction, refractive error, uncorrected distance visual acuity (UDVA), and corrected distance visual acuity (CDVA). Additional evaluations included binocular defocus curves, contrast sensitivity, spectacle independence, patient satisfaction, and visual symptoms at 1, 3, 6, and 12 months postoperatively.
Results
The study included 44 eyes (22 patients) in the Vivity group, 22 eyes (11 patients) in the Synergy group, and 54 eyes (27 patients) in the PanOptix group. There were no significant differences in UDVA, CDVA, and refractive outcomes among the groups postoperatively. In the defocus curve analysis, the PanOptix and Synergy groups showed no difference at 1 month, but Synergy demonstrated better near visual acuity at 3, 6, and 12 months. The Vivity group consistently showed lower intermediate and near visual acuity compared to the trifocal IOL groups. Spectacle independence and near vision satisfaction were lower in the Vivity group, while the two trifocal groups showed no significant difference.
Conclusion
Both the Synergy and PanOptix IOLs provided good intermediate and near visual acuity, with the Synergy IOL showing superior performance at specific defocus levels over time. The Vivity IOL demonstrated relatively lower intermediate and near visual acuity compared to the trifocal IOLs.

Purpose
It is well known that glistening a are vacuoles that are pressent within an IOL and may induce clinical effects, such as decreased visual acuity. the purpose of this study is to assess the clinical effects of glistenings in a patient whose had chosen a multifocal IOL, in terms of visual acuity and contrast sensitivity values.
Methods
We studied a cohort of patients whose had cataract surgery with multifocal intraocular lens implantation during the period of 2011 to 2019, we randomly selected 55 patients, the following data was captured, days from surgery, multifocal IOL type, grade of glistenings ) Miyata subjective scale, distance uncorrectted visual acuity, near uncorrected visual acuity, contrast sensitivity values at different frequencies, comorbidities, age,and sex. a multi variate analysis was performed, we excluded patients which had ocular any ocular pathology after the implantation of the multifocal IOL.
Results
We found 45.4% for men, 54.55% for women, mean age 56, the groups were classified according to the the Miyata grading scale, the most prevalent grade was group II, no significant association between visual acuity, contrast sensitivity values and grades I and II of the Miyata scale, we found a significant correlation between decreased visual acuity and decreased contrast sensitivity values in high frequencies (<0.05) no="" correlation="" was="" found="" between="" time="" of="" iol="" implantation="" and="" grade="">0.05)>
Conclusion
Glistenings are prevalent in some IOL platforms, however it seems that visual acuity is decreased when the presence of glistenings is significant (grade 4 of the Miyata scale). No association was found between time of implantation and grade of glistenings.

Purpose
Standard straylight assessment at 7 degrees for glare quantification shows similar straylight values across different multifocal diffractive intraocular lenses (IOLs). This study explores whether modifying the test procedure can enhance the sensitivity of glare measurements.
Methods
This clinical comparative study evaluated patients implanted with Clareon PanOptix (Alcon), TECNIS Synergy (J&J) diffractive multifocal IOLs, and monofocal controls, with a total of 35 patients included. Straylight measurements were performed in each eye at 7 and 2.5 degrees using the standard and modified C-Quant (Oculus) device. The straylight values (expressed as logs) between the groups were compared using the Kruskal-Wallis test, with a P-value of <0.05 considered="" statistically="">0.05>
Results
At 7 degrees, straylight measurements were 1.10�0.10 for eyes implanted with Clareon PanOptix, 0.98�0.16 for TECNIS Synergy, and 1.06�0.24 for monofocal IOLs (P=.24). At 2.5 degrees, using the modified C-Quant, straylight was 1.35�0.10 for Clareon PanOptix, 1.56�0.08 for TECNIS Synergy, and 1.28�0.24 for monofocal IOLs (P<.001). a="" difference="" of="" 0.3="" indicates="" a="" doubling="" of="" glare="" effects.="" at="" 2.5="" degrees,="" the="" tecnis="" synergy="" group="" showed="" the="" highest="" increase="" in="" straylight,="" with="" statistically="" significantly="" higher="" values="" compared="" to="" clareon="" panoptix=""><.001) and="" monofocal="" iols="" (p=".001)." no="" significant="" difference="" was="" found="" between="" clareon="" panoptix="" and="" the="" monofocal="" iols="" at="" 2.5="" degrees="" (p="">
Conclusion
Straylight measurements at 2.5 degrees were higher for both multifocal and monofocal IOLs compared to those at 7 degrees, with the most pronounced increase observed in the TECNIS Synergy group. Testing at lower angles can better identify multifocal IOL designs that may increase the risk of photic phenomena in pseudophakic patients.
