Methods for evaluating quality of life and vision in patients undergoing lens refractive surgery

The Effect of Blue-light Filtering Intraocular Lenses on the Development and Progression of Macular Atrophy in Eyes With Neovascular Age-related Macular Degeneration

PURPOSE

To assess the effect of blue-light filtering (BLF) intraocular lenses (IOLs) on the development and progression of macular atrophy (MA) in eyes with neovascular age-related macular degeneration (nAMD).

DESIGN

Retrospective, clinical cohort study.

METHODS

The study included patients with nAMD with anti-vascular endothelial growth factor (VEGF) injections who underwent uneventful cataract surgery between 2007 and 2018 with follow-up until June 2023. Subsequent MA rates were compared between subjects who received a BLF IOL or a non-BLF IOL. All optical coherence tomography scans were manually reviewed in a masked manner regarding patient baseline variables and IOL status by an experienced research technician. By using Heidelberg software, the area of MA was manually evaluated and calculated (mm2) by the program. The overall risk of developing new-onset MA and the effect of IOL type on disease progression were assessed. Death was included as a censoring event.

RESULTS

Included were 373 eyes of 373 patients (mean age, 78.6 ± 6.7 years at surgery; 67.4% were female). BLF IOLs were implanted in 206 eyes, and non-BLF IOLs were implanted in 167 eyes with comparable follow-up times (3164 ± 1420 days vs 3180 ± 1403 days, respectively, P = .908) and other baseline parameters (age, gender, corrected distance visual acuity, macular thickness, cumulative number of anti-VEGF injections). Nine preexisting and 77 new-onset MA cases were detected, with similar distribution between BLF and non-BLF eyes (P = .598 and P = .399, respectively). Both univariate Kaplan-Meier (P = .366) and multivariate Cox regression analyses adjusted for age and gender showed that BLF-IOLs were comparable to non-BLF IOLs regarding hazard for new-onset MA (hazard ratio [HR], 1.236; 95% CI, 0.784-1.949; P = .363). Final MA area at the last visit was 5.14 ± 4.71 mm2 for BLF IOLs and 8.56 ± 9.17 mm2 for non-BLF IOLs (P = .028), with the mean annual MA area increase of 0.78 ± 0.84 mm2 and 1.26 ± 1.32 mm2, respectively (P = .042).

CONCLUSIONS

BLF IOLs did not show added benefit over non-BLF IOLs in terms of MA-free survival but were associated with less progression over time in a cohort of patients with nAMD.

Three Patient-Reported Outcomes Questionnaires in Japanese Patients Undergoing Cataract Surgery with Trifocal IOL Implantation

Purpose

To analyze the patient-reported-outcomes obtained after trifocal intraocular lens (IOL) bilateral implantation in Japanese patients using three different validated questionnaires.

Methods

Fifty-three patients implanted with the FineVision HP IOLs (Beaver-Visitec International, Inc. USA) were enrolled in this prospective-study. At 3-months, refraction (spherical equivalent [SE] and cylinder), logMAR uncorrected distance visual acuity (UDVA), and corrected distance visual acuity (CDVA) were obtained. Specifically, patient-reported-outcomes were evaluated using the NEI VFQ-25, the Catquest-9SF, and the PRSIQ questionnaires.

Results

The mean SE and refractive cylinder were 0.00±0.22D and -0.07±0.23D, respectively. A 98.11% of eyes were within ±0.50D and 100% were within ±1.00D of the SE. A 93.40% of the eyes showed equal or less than 0.50D of astigmatism and 100% of eyes equal or less than 1.00D. The mean value for monocular UDVA was -0.05±0.07 logMAR and the mean value for monocular CDVA was -0.07±0.06 logMAR. 87.74% and 92.45% of the eyes showed 20/20 or better monocular UDVA and CDVA, respectively, with 97.17% and 98.11% showing 20/25 or better for UDVA and CDVA, respectively. The NEI VFQ-25 outcomes showed very high scores across all categories, with mean general vision, distance and near activities values of 86.70±6.35, 96.23±7.72 and 92.14±10.74, respectively. The outcomes for the Catquest-9SF questionnaire showed that 90.57% of patients did not report difficulty in their everyday-life with their sight, and 100% of them were "very or quite satisfied" with their sight at present. The PRSIQ outcomes revealed that 100%, 98.11% and 98.11% of patients did not need glasses or contacts for far, intermediate and near vision, respectively.

Conclusion

The results of the patient-reported-outcomes questionnaires indicated that patients implanted bilaterally with the FineVision HP IOL have high vision and health related quality-of-life scores, with a high spectacle independence rate and high patient satisfaction.

Quality of Life after Cataract Surgery

Background: The impact of medical intervention on a patient's quality of life (QoL) is more and more important. Treatment success is defined not only in terms of the success of the procedure performed but also with regard to its impact on different areas of the patient's life. The aim of the study was to assess the QoL of patients after cataract surgery and identify factors that affect it. Methods: Between January and March 2018, a survey was carried out among 100 patients who had undergone cataract surgery with intraocular lens implantation at the 'Spektrum' Clinical Ophthalmology Centre in Wrocław. The World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire and Illness Acceptance Scale (AIS) were used. Results: Most respondents (67%) rated their overall health as very good. The median score on the AIS was 34 (31.5-39), indicating a high level of illness acceptance. There was no statistically significant relationship (p > 0.05) between sex and QoL nor between the level of illness acceptance and QoL. We found no statistically significant relationships between place of residence and QoL (p > 0.05) nor between place of residence and AIS. Conclusions: The respondents reported the highest QoL scores for the environment domain and the lowest QoL scores for the social relationships domain. QoL had a positive impact on illness acceptance among the study patients. Younger patients (aged 50 or under) reported significantly higher scores for all the domains of QoL. Being employed was found to be associated with better QoL and greater illness acceptance.

Risk Factors for Corneal Monochromatic Aberrations and Implications for Multifocal and Extended Depth-of-Focus Intraocular Lens Implantation

PURPOSE

To discuss factors influencing corneal aberrations that might influence the optical quality after intraocular lens (IOL) implantation.

METHODS

PubMed and Scopus were the main resources used to search the medical literature. An extensive search was performed to identify relevant articles concerning factors influencing the level of corneal aberrations as of August 27, 2023. The following keywords were used in various combinations: corneal, aberrations, defocus, astigmatism, spherical aberration, coma, trefoil, quadrafoil, intraocular lens, and IOL.

RESULTS

Conclusive evidence is lacking regarding the correlation between age and changes in corneal aberrations. Patients with astigmatism have greater corneal higher-order aberrations than those with minimal astigmatism, particularly concerning trefoil and coma. Increased levels of corneal higher-order aberrations are noted following contact lens wear, in patients with dry eye disease, and with pterygium. Increased higher-order aberrations have been reported following corneal refractive surgery and for 3 months following trabeculectomy; regarding intraocular lens surgery, the results remain controversial.

CONCLUSIONS

Several factors influence the level of corneal higher-order aberrations. Multifocal and extended depth-of-focus IOLs can share similarities in their optical properties, and the main difference arises in their design and performance with respect to spherical aberration. Preoperative evaluation is critical for proper IOL choice, particularly in corneas with risk of high levels of aberrations. [J Refract Surg. 2024;40(6):e420-e434.].

The influence of personality on the quality of vision after multifocal intraocular lens implantation

OBJECTIVE

To assess the possible correlation between patients' personality traits and subjective perception of quality of vision (QoV), after multifocal intraocular lens (mIOL) implantation.

METHODS

patients who had bilateral implantation of a non-diffractive X-WAVE or a trifocal lens were assessed 6 months postoperatively. Patients answered the NEO-Five Factor Inventory (NEO-FFI-20) questionnaire ("Big Five five-factor personality model") to examine their personality. Six months following surgery, patients were asked to fill a QoV questionnaire where they graded the frequency of 10 common visual symptoms. Primary outcomes were to evaluate the correlation between personality scores and the reported frequency of visual disturbances.

RESULTS

The study comprised 20 patients submitted to bilateral cataract surgery, 10 with a non-diffractive X-WAVE lens (AcrySof® IQ Vivity) and 10 with a trifocal lens (AcrySof® IQ PanOptix). Mean age was 60.23 (7.06) years. Six months following surgery, patients with lower scores of conscientiousness and extroversion reported a higher frequency of visual disturbances (blurred vision, P  =  .015 and P  =  .009, seeing double images P  =  .018 and P  =  .006, and having difficulties focusing, P  =  .027 and P  =  .022, respectively). In addition, patients with high neuroticism scores had more difficulty focusing (P  =  .033).

CONCLUSIONS

In this study, personality traits such as low conscientiousness and extroversion and high neuroticism significantly influenced QoV perception 6 months after bilateral multifocal lens implantation. Patients' personality questionnaires could be a useful preoperative assessment test to a mIOL.

Comparison of visual outcomes in adult patients with different types of developmental cataracts after toric multifocal intraocular lenses implantation

PURPOSE

 To analyze and compare the visual performance and patient satisfaction following the implantation of toric multifocal intraocular lenses (TMIOLs) in adult patients with different types of developmental cataracts (DC) accompanied by corneal astigmatism (CA).

METHODS

 This is a prospective observational cohort study. Patients diagnosed with DC aged 18-30 years were divided into three groups according to the anatomic location of the lens opacity: cortical, nuclear, and posterior subcapsular (PSC) groups, and implanted with TMIOLs. Visual acuity (VA), postoperative refractive astigmatism (RA), intraocular lens (IOL) rotation, high-order aberrations (HOAs), modulation transfer function (MTF) curve, and Strehl ratio were compared. The functional vision and incidence of photic phenomena were surveyed using questionnaires.

RESULTS

 Fifty-five eyes of 37 patients were enrolled and completed a 1-year follow-up. The mean CA was 2.06 ± 0.79 D preoperatively, and the mean RA was 0.29 ± 0.30 D 3-month postoperatively. The IOL rotation was 2.48° ± 1.89°, with no deviation > 10°. At 12 months, mean uncorrected distance VA improved from 0.93 ± 0.41 preoperatively to 0.08 ± 0.08 logarithm of the minimum angle of resolution (logMAR), mean uncorrected near VA increased from 0.45 ± 0.30 preoperatively to 0.12 ± 0.11 logMAR, and mean uncorrected intermediate VA was 0.14 ± 0.08 logMAR. The cortical and nuclear groups displayed better improvements in uncorrected near and intermediate VA than that in the PSC group. Similar results were observed in the 3-month defocus curves, HOAs, MTF curve, halo incidence, and near vision satisfaction.

CONCLUSION

In adult patients with DC accompanied by CA, TMIOLs implantation achieved good postoperative visual outcomes and significantly reduced glasses dependency. Patients with cortical or nuclear lens opacity showed better whole-course VA and quality of vision, while patients with PSC opacity showed unsatisfactory near vision and suffered more photic phenomena.

Spherical aberrations and their role in modern ophthalmology

Spherical aberration is an imperfection of the optical system of the human eye. The role of spherical aberration of the human eye in the quality of vision and pseudoaccommodation is reviewed. Spherical aberration is an imperfection of the optical system of the human eye. In most cases, due to well-developed neuroadaptation, it is insignificant for the perception of the image. Nevertheless, its role in modern ophthalmology is far from straightforward. On the one hand, there are clinical scenarios in which an excess of spherical aberration degrades the retinal image and leads to a high dissatisfaction rate among patients.©Recently, there is a growing interest in the modulation of spherical aberration in the clinical setting. Modern intraocular lenses as well as laser refractive procedures are aimed at interfering with spherical aberrations of the optical system in order to increase range of pseudoaccommodation. Here, we review the role of spherical aberration of the human eye in the quality of vision and pseudoaccommodation.

Risk evaluation of carbapenem-induced liver injury based on machine learning analysis

INTRODUCTION

Information regarding carbapenem-induced liver injury is limited, and the rate of liver injury caused by meropenem (MEPM) and doripenem (DRPM) remains unknown. Decision tree (DT) analysis, a machine learning method, has a flowchart-like model where users can easily predict the risk of liver injury. Thus, we aimed to compare the rate of liver injury between MEPM and DRPM and construct a flowchart that can be used to predict carbapenem-induced liver injury.

METHODS

We investigated patients treated with MEPM (n = 310) or DRPM (n = 320) and confirmed liver injury as the primary outcome. We used a chi-square automatic interaction detection algorithm to construct DT models. The dependent variable was set as liver injury from a carbapenem (MEPM or DRPM), and factors including alanine aminotransferase (ALT), albumin-bilirubin (ALBI) score, and concomitant use of acetaminophen were used as explanatory variables.

RESULTS

The rates of liver injury were 22.9% (71/310) and 17.5% (56/320) in the MEPM and DRPM groups, respectively; no significant differences in the rate were observed (95% confidence interval: 0.710-1.017). Although the DT model of MEPM could not be constructed, DT analysis showed that the incidence of introducing DRPM in patients with ALT >22 IU/L and ALBI scores > -1.87 might be high-risk.

CONCLUSIONS

The risk of developing liver injury did not differ significantly between the MEPM and DRPM groups. Since ALT and ALBI score are evaluated in clinical settings, this DT model is convenient and potentially useful for medical staff in assessing liver injury before DRPM administration.

EVO/EVO+ Visian Implantable Collamer Lenses for the correction of myopia and myopia with astigmatism

INTRODUCTION

Intraocular lens implantation in phakic eyes for the correction of refractive error is currently a widespread procedure. The EVO and EVO+ Visian Implantable Collamer Lenses (ICL) are two of the most prevalent lenses implanted. They incorporate a central orifice to avoid the need for iridotomy. The main difference between both ICL is the higher optical diameter zone provided by the EVO+, allowing a better quality of vision at night. This review aims to provide an overview of the current ICL models available for correcting myopia and myopic astigmatism.

AREAS COVERED

During the last decade, more than 100 scientific papers analyzing the performance of EVO and EVO+ lenses have been published. This review describes the objective visual performance achieved with the implantation of central hole ICL lenses and the subjective perception of the patients implanted with these lenses. In addition, the safety and the potential complications associated with undergoing an EVO and EVO+ ICL implantation have been addressed.

EXPERT OPINION

Refractive surgeons and candidates to undergo ICL implantation should be aware of the excellent safety and visual outcomes provided by the implantation of central hole ICL lenses. However, future research could address minor issues currently not resolved.

Latest Development in Extended Depth-of-Focus Intraocular Lenses: An Update

In recent years, there has been an overwhelming influx of different types of intraocular lenses (IOLs) as treatment for presbyopia. The extended depth-of-focus (EDOF) technology creates a single elongated focal point to enhance depth of focus, in contrast to the multiple foci of multifocal (MF) lenses. In this way, the EDOF lenses aim to reduce photic phenomena, glare, and halos, which have been reported in MF IOLs. A potential disadvantage of this is a blur due to decreased retinal image quality when the amount of the aberrations is increased excessively. Multifocality and EDOF characteristics are not exclusive of each other. Frequently, EDOF IOLs are combined with MF optical designs, a bifocal IOL may exhibit EDOF characteristics, likewise an aspheric monofocal IOL or a diffractive or refractive trifocal IOL. Thus, EDOF lenses are commonly subjected to confusion. A wide range of different types of EDOF lenses are available on the market to surgeons. In this practical update, we aim to clarify what is a true EDOF lens, classify the different types of the EDOF lenses based on their optical principle and review their recently reported outcomes. Comprehensive patient examination and selection, combined with knowledge of the most updated options and adequate patient counseling, can avoid dissatisfaction and yield the desired outcomes.

Association of Blue Light-Filtering Intraocular Lenses With All-Cause and Traffic Accident-Related Injuries Among Patients Undergoing Bilateral Cataract Surgery in Finland

IMPORTANCE

Blue light-filtering (BLF) intraocular lenses (IOLs) have been widely used in clinical practice for more than 20 years and have been implanted in millions of patients with cataracts worldwide. However, little evidence on the association of BLF IOLs with injuries is available.

OBJECTIVE

To assess the association of BLF IOLs with all-cause and traffic accident-related injuries and quality of vision while driving after bilateral cataract surgery.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective registry-based cohort study included patients who underwent bilateral cataract surgery between September 3, 2007, and December 14, 2018, and were followed until December 14, 2021. Surgery was performed at the Department of Ophthalmology, Kymenlaakso Central Hospital, Kotka, Finland. The 4986 participants received non-BLF IOLs (n = 2609) or BLF IOLs (n = 2377) in both eyes. Patients undergoing bilateral surgery between 2015 to 2016 with non-BLF IOLs (n = 102) or BLF IOLs (n = 91) and currently driving a car were interviewed using a structured questionnaire for visual performance while driving.

EXPOSURES

Follow-up for a mean (SD) of 2166 (1110) days after second eye surgery.

MAIN OUTCOMES AND MEASURES

Kaplan-Meier and multivariable Cox proportional hazards regression analyses for the risk of all-cause and traffic accident-related injuries after surgery in the second eye obtained from the patient medical records were assessed. To improve follow-up precision, both death and the end of the follow-up were used as censoring events.

RESULTS

A total of 4986 patients were included in the analysis (1707 [34.2%] men and 3279 [65.8%] women; mean [SD] age, 73.2 [8.6] years at the first surgery and 74.3 [8.8] years at the second). Injury-free survival rates preceding the first eye surgery were comparable between the non-BLF and BLF IOL groups (hazard ratio adjusted for age and sex, 0.95 [95% CI, 0.81-1.13; P = .57]). In multivariable Cox proportional hazards regression analysis controlling for age and sex, the use of BLF IOLs showed no advantage in overall injuries compared with the use of non-BLF IOLs (hazard ratio, 0.99 [95% CI, 0.88-1.11]; P = .85) or in any injury subtype. Subjective visual performance parameters for driving were all comparable between the non-BLF and BLF IOL groups except for glare when driving in the dark (evening or night), which occurred among 9 of 80 patients with BLF IOLs compared with 0 of 83 non-BLF IOLs (P < .001).

CONCLUSIONS AND RELEVANCE

The findings of this cohort study suggest that use of BLF IOLs was not associated with reduced risk of injuries, whereas glare during nighttime driving was significantly worse in the BLF IOL group with pseudophakia.

A Comparison of Visual Quality and Contrast Sensitivity between Patients with Scleral-Fixated and In-Bag Intraocular Lenses

Purpose: To analyze visual quality and contrast sensitivity in patients after intraocular lens (IOL) implantation with sutured scleral fixation. Setting: Chang Gung Memorial Hospital, Taoyuan, Taiwan. Design: Retrospective observational study. Methods: Data on the refractive outcome, visual acuity, and subjective visual symptoms in patients with scleral-fixated or in-bag IOL implantation were collected from September 2019 to March 2020. We also investigated patients’ postoperative higher-order aberrations (HOAs) and dysphotopsia using a wavefront aberrometer and glaretester, respectively. The following values were compared: corrected distance visual acuity, spherical equivalent, root mean square values for aberrations, and contrast sensitivity. Results: A total of 23 eyes implanted with scleral-fixated IOL and 74 eyes with in-bag IOL were studied. The mean postoperative spherical equivalent and logarithm of the minimum angle of resolution after scleral fixation were −1.09 ± 3.32 D and 0.20 ± 0.17, respectively. The ocular HOAs were higher in the scleral-fixation group than in the in-bag group (p = 0.001). Contrast sensitivity was negatively associated with age, and it was similar between the two groups after controlling for the age effect. Conclusions: Ocular HOAs and refractive errors were higher in the scleral-fixation group than in the in-bag group. However, no significant difference was noted in contrast sensitivity between advanced scleral fixation and in-bag IOL implantation.

Determinants of Subjective Quality of Vision After Phakic Intraocular Lens Implantation

PURPOSE

To evaluate postoperative subjective quality of vision in patients who underwent Implantable Collamer Lens (ICL) (STAAR Surgical) implantation for correction of myopia and to identify potential predictive parameters.

METHODS

In this single-center cross-sectional study, a total of 162 eyes of 81 patients (58 women, 23 men) who underwent ICL implantation were analyzed. The Quality of Vision (QOV) questionnaire was used to assess patient-reported outcomes. Baseline characteristics (eg, age), treatment parameters (eg, surgical corrected refraction), and refractive (eg, residual refraction) and visual (eg, uncorrected distance visual acuity) outcomes were analyzed regarding their effect on QOV.

RESULTS

Mean age was 33.3 ± 7.0 years (range: 21 to 51 years) and mean preoperative spherical equivalent was -8.42 ± 2.49 diopters (D) (range: -3.25 to -14.38 D). After a mean postoperative follow-up period of 19 ± 14 months (range: 6 to 54 months), the safety index score was 1.23 ± 0.21 and the efficacy index score was 1.17 ± 0.22. The mean QOV scores were 35.5 ± 11.3, 32.2 ± 11.1, and 23.3 ± 16.1 for frequency, severity, and bothersomeness, respectively. The most frequently experienced symptoms were halos (90.1%) and glare (66.7%). Halos appeared in 66.7% of the patients "occasionally" and 5 of them (6.2%) experienced them "very often." Only 1 patient (1.2%) classified halos as "very bothersome." Patients older than 36 years reported visual symptoms more frequently (P < .05) and showed higher bothersomeness scores (P = .01).

CONCLUSIONS

Halos are the most commonly perceived long-term visual disturbance after myopic ICL implantation with a central hole. Visual symptoms can persist more than 6 months postoperatively, causing only minor disturbances in most cases. Older patients seem more prone to experiencing these symptoms.

The relationship between patient satisfaction and visual and optical outcome after bilateral implantation of an extended depth of focus multifocal intraocular lens

Purpose

To evaluate patient satisfaction after implantation of the Tecnis Symfony multifocal intraocular lens (MIOL).

Methods

120 eyes of 60 subjects with senile cataract were bilaterally implanted with the Tecnis Symfony IOL. Follow-up examination was performed 6 months postoperatively. Main outcome measures included uncorrected and corrected distance and near visual acuity, manifest refraction, and visual quality metrics. According to their subjective symptoms patient were divided in two groups: satisfied and unsatisfied.

Results

Uncorrected intermediate (0.15 ​± ​0.11 vs 0.18 ​± ​0.01, P ​= ​0.04) and near (0.26 ​± ​0.12 vs 0.31 ​± ​0.11, P ​= ​0.04) (UIVA, UNVA) log MAR visual acuity was significantly better, cylindrical error less (0.31 ​± ​0.36 vs 0.67 ​± ​0.29, P ​= ​0.05), axial length (AL) smaller (23.68 ​± ​1.3 vs 24.22 ​± ​1.6, P ​= ​0.05), Strehl ratio higher (0.08 ​± ​0.08 vs 0.05 ​± ​0.04, P ​= ​0.03) and mesopic pupil larger (4.3 ​± ​1.1 vs 3.7 ​± ​1.05, P ​= ​0.01) among satisfied patients.Residual cylinder, Strehl ratio, halos, mesopic pupil diameter and UNVA were significant predictors of patient satisfaction. Uncorrected distance visual acuity, higher order Strehl ratio and pupil diameter were significant predictors of halos. Near visual acuity significantly correlated (P ​= ​0.018, R ​= ​0.22) with axial length.

Conclusions

Uncorrected cylindrical error, poor reading quality, larger pupil and halos seem to be the most disturbing factors for patients implanted with the Tecnis Symfony IOL.

Comparison of Visual Outcomes and Quality of Life in Patients with High Myopic Cataract after Implantation of AT LISA Tri 839MP and LS-313 MF30 Intraocular Lenses

Purpose

To investigate the benefits of multifocal lens in patients with high myopic cataract and compare the clinical effects between AT LISA tri 839MP and MPlus LS-313 MF30 intraocular lenses (IOLs) in high myopic eyes.

Methods

This retrospective cohort study analyzed 60 eyes with axial length >26 mm in 40 patients. Thirty eyes were implanted with MF30, and the remaining 30 eyes were implanted with 839MP. Postoperative uncorrected distance visual acuity (UDVA), best corrected distance visual acuity (BCDVA), uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA), defocus curve, modulation transfer function (MTF) curve, Strehl ratio (SR), and complications were compared between the two groups.

Results

All vision outcomes were significantly improved in both groups (p < 0.05). There was no significant between-group difference in UDVA at 1 and 3 months postoperatively (p > 0.05). However, UIVA and UNVA were significantly better in the 839MP group (p < 0.05). The VF-14 score, especially for near vision quality, was significantly higher in the MF30 group (2.2 ± 0.9 vs. 0.8 ± 0.7; p ≤ 0.001). The SR of both groups significantly increased postoperatively (p < 0.05). All the 3-month MTF curve values (MTF 10 total, MTF 10 internal, MTF 30 total, and MTF 30 internal) were significantly better in the 839MP group (p < 0.05). Meanwhile, all the high-order aberration values (coma, spherical aberration, and trefoil) were significantly greater in the MF30 group (p < 0.05).

Conclusion

Multifocal IOL implantation achieves good quality of distance, intermediate, and near vision in patients with high myopia, improving their quality of life. Both 839MP and MF30 IOLs can provide good distance vision, but 839MP performs better in near and intermediate vision. However, for some patients with an extra-long optic axis, MF30 may be a good choice because of its wider range of degrees.

Evaluation of Disk Halo Size and Identification of Correlated Factors in Myopic Adults

This study aimed to evaluate glare source-induced disk halo size and assess its correlation with higher-order aberrations (HOAs), pupillometry findings, and contrast sensitivity in myopic adults (aged 23.8 ± 4.4 years). In this cross-sectional study, 150 eyes of 150 patients were assessed. All patients underwent routine ophthalmic examinations, wavefront aberrometry, halo size measurement, dynamic pupillometry, and contrast sensitivity tests. Spearman's correlation analysis and independent sample t-tests were performed for data analysis. The mean halo radius was 82.5 ± 21.8 and 236.7 ± 52.2 arc min at 5 and 1 cd/m² luminance levels, respectively. The values were inversely correlated with internal spherical aberration (SA) (r = −0.175, p = 0.032 and r = −0.241, p = 0.003, respectively), but not correlated with spherical equivalent (SE, both p > 0.05). Positive correlations were observed between halo radius and pupil size, contraction amplitude, and dilation speed during pupillary light reflex. Halo radii at 5 and 1 cd/m² luminance levels were not significantly correlated with the area under the log contrast sensitivity function (r = −0.093, p = 0.258 and r = −0.149, p = 0.069, respectively). The mean halo radius was not clinically different between myopic and healthy eyes at 5 cd/m² luminance level and did not differ significantly between the high and low-to-moderate myopia at 5 and 1 cd/m² luminance levels (all p > 0.05). According to a stepwise linear regression model, the internal SA had a negative effect on the halo radius under low photpic condition; the average pupil diameter, internal SA and corneal HOAs played a large role in determining the halo radius under mesopic condition.

Should We Perform Early Cataract Surgery? A Patient Reported Outcome Study

Purpose

Current guidance states that access to cataract surgery should not be restricted by visual acuity (VA); nevertheless, 6/12 is used as a cut-off criterion in some health institutions. This study aims to determine the benefits of performing cataract surgery in patients with VA of 6/9 or better in both eyes; determine whether these benefits change over time; and compare the benefit observed between early first eye and second eye surgery.

Patients and Methods

Fifty adults with VA at least 6/9 in the worst eye and no ocular comorbidity were recruited. The Visual Function Index (VF-14) and Impact of Visual Impairment (IVI) questionnaires were conducted pre-operatively, 4 months post-operatively, and 12 months post-operatively. The t-test or a non-parametric equivalent was used to compare averages between groups.

Results

The mean change in VF-14 from baseline to 4 months was 16.43 (95% CI 12.49–20.50, p < 0.001) and the median change in IVI was 6.5 (IQR 9.75, p < 0.001). There was no significant difference between 4-month and 12-month follow-up (p > 0.05). There was no significant difference in the change in visual function between the first and second eye surgery (p > 0.05).

Conclusion

This study provides evidence that visual function improves after cataract surgery in patients with pre-operative VA of 6/9 or better. The improvement observed was clinically significant and unchanged a year after surgery. Visual function improved after second eye as much as after first eye surgery. Assessing patient reported visual function may give a more realistic indication of the benefit of early cataract surgery than relying on VA alone.

Reliability and Validity of the Persian Version of Quality of Life Impact of Refractive Correction Questionnaire

PURPOSE

To evaluate the psychometric properties of the Persian version of quality of life impact of refractive correction (QIRC) questionnaire and its utility in assessment of refractive error-related quality of life (QoL) following photorefractive keratectomy (PRK).

METHODS

Patients with low-to-moderate myopia (-0.75 to - 6.0) were enrolled in this study. Standard alcohol-assisted PRK was performed in all patients. The QIRC questionnaire was translated into a Persian version using the standard method. Patients completed QIRC questionnaire preoperatively and 3-month postoperatively. A group of patients completed the questionnaire twice preoperatively. Psychometric properties were evaluated by internal consistency (Cronbach's α), item-total correlation, and known group construct validity. Intraclass correlation coefficient (ICC) were used to examine the repeatability.

RESULTS

One hundred forty-seven patients (60 males and 87 females) with a mean age of 26.3 ± 5.5 (range, 18-39) years were enrolled. Cronbach's α for total score was 0.923. Item-total correlation was above 0.3 for all items. ICC was 0.978 for total score. Preoperatively, predominantly contact lens wearers showed significantly better total QIRC score than predominantly spectacle wearers (P = 0.017), which showed good known group validity. Total QIRC score significantly increased from 41.31 ± 6.69 preoperatively to 50.47 ± 7.26 postoperatively (P < 0.0001). Improvement in total QIRC score was observed both in contact lens wearers and spectacle wearers.

CONCLUSION

The Persian version of QIRC questionnaire is a valid and reliable tool. Refractive error-related QoL assess by QIRC was significantly improved after PRK in an Iranian population.

Visual performance and patient satisfaction after implantation of extended range-of-vision IOLs: bilateral implantation vs 2 different mix-and-match approaches

PURPOSE

To compare the visual outcomes and patient satisfaction after bilateral implantation of an extended range-of-vision intraocular lens (ERoV IOL) (Tecnis Symfony) vs 2 different mix-and-match approaches combining the ERoV IOL with bifocal IOLs.

SETTING

Glory Seoul Eye Clinic, Seoul, South Korea.

DESIGN

Prospective observational nonrandomized comparative study.

METHODS

Patients undergoing cataract surgery were distributed into 3 groups based on their lifestyle and near visual demands: bilateral Symfony IOL, mix-and-match Symfony IOL with bifocal +3.25 diopters (D) IOL, and Symfony IOL with bifocal +4.0 D IOL. Binocular uncorrected visual acuity for distance, intermediate, and near, manifest refraction, defocus curve, contrast sensitivity, and subjective visual perception and satisfaction (photic phenomena, spectacle independence, and patient satisfaction) were evaluated at 1 week, 1 month, and 3 months postoperatively.

RESULTS

The study comprised 103 people (206 eyes). There were no significant differences for uncorrected visual acuity between groups for distance, intermediate, and near vision (P > .05). Contrast sensitivity under low and high luminance conditions was not different between groups (P > .05). Influence of glare on image perception was found to reduce contrast sensitivity more in the bilateral group for smaller target sizes (P < .05). Patients implanted bilaterally with Symfony IOLs reported photic phenomena more frequently than those implanted with the mix-and-match combinations.

CONCLUSIONS

All combinations evaluated provided good visual outcomes for distance, intermediate, and near. The lower incidence of photic phenomena reported by patients, and the lower reduction on contrast sensitivity for low illumination levels with the presence of glare, suggest that mix-and-match approaches might be a better option compared with bilateral implantation of ERoV IOLs.

Visual function and subjective perception of vision after bilateral implantation of monofocal and multifocal IOLs: a randomized controlled trial

PURPOSE

To examine monocular and binocular visual function and patient-reported outcomes after implantation of multifocal IOLs (mIOLs) or monofocal IOLs, using a rigorous series of clinical assessments.

SETTING

BMI Southend Hospital, United Kingdom.

DESIGN

Prospective, randomized, double-masked clinical trial.

METHODS

One hundred patients were randomized for bilateral implantation of either a Bi-Flex 677MY mIOL or a Bi-Flex 677AB IOL and were assessed at 3 to 6 months (V1) and 12 to 18 months (V2). Primary outcomes included distance, intermediate, and near logarithm of the minimum angle of resolution (logMAR) visual acuities (VAs) and defocus curve profile assessment. Secondary outcomes included reading speed, contrast sensitivity (CS), and the subjective perception of quality of vision.

RESULTS

Forty-seven subjects with monofocal IOL and 43 mIOL subjects completed the study. Uncorrected (mIOL: 0.10 ± 0.09 logMAR; IOL: 0.09 ± 0.11 logMAR) and corrected (mIOL: 0.04 ± 0.06 logMAR; IOL: 0.01 ± 0.07 logMAR) distance VAs were comparable (P > .05). Uncorrected near VA (mIOL: 0.23 ± 0.13 logMAR; IOL: 0.55 ± 0.20 logMAR, P < .001) and distance-corrected near VA (mIOL: 0.24 ± 0.13 logMAR; IOL: 0.54 ± 0.17 logMAR, P < .001) were significantly improved with mIOLs. There was no significant difference in distance-corrected intermediate VA (mIOL: 0.38 ± 0.13 logMAR; IOL: 0.39 ± 0.13 logMAR, P = .431). Defocus curves demonstrated an increased range-of-focus among mIOLs (mIOL: 4.14 ± 1.10 diopter [D]; IOL: 2.57 ± 0.77 D). Pelli-Robson CS was different at V1 (P < .001) but similar by V2 (P = .059). Overall satisfaction was high (>90%) in both groups for distance tasks whereas significantly different for near tasks (mIOL, 18.45 ± 16.53 logUnits; IOL, 55.59 ± 22.52 logUnits).

CONCLUSIONS

Uncorrected near visual acuity was demonstrably better with mIOLs and there was greater subjective satisfaction with quality of near vision. Halos reported by the mIOL group were significant compared with the IOL group but did not show an adverse effect on overall satisfaction.

One-year Results of Health-related and Vision-related Quality of Life After Clear Lens Extraction and Multifocal Intraocular Lens Implantation

PURPOSE

Multifocal intraocular lenses (MIOLs) are effective in treating presbyopia before cataracts develop. This study measured health-related quality of life (HRQoL) and vision-related quality of life (VRQoL) after clear lens extraction (CLE) and MIOL implantation.

DESIGN

Before-and-after study METHODS: Patients were treated in Medilaser Coronaria, CorGroup, Oulu, Finland. HRQoL was measured by a generic 15-dimension (15D) instrument. VRQoL was measured with Visual Function Index-14 (VF-14) questionnaire.

RESULTS

CLE and MIOL implantation was performed in 137 patients. The patient age was 57 ± 6.2 years (mean ± standard deviation), and 58% were women. The near add was 2.1±0.3 diopters (D). The overall HRQoL 15D score increased from 0.938±0.058 to 0.955±0.057 at 6 months (P < .0001 vs baseline) and to 0.948±0.060 at 1 year (P = .02 vs baseline). The VRQoL VF14 score increased from 85.32±15.57 to 96.57±5.07 at 6 months (P < .0001 vs baseline) and to 96.61±6.48 at 1 year (P < .0001 vs baseline). The increase of HRQoL was correlated with the increase of VRQoL (P < .04).

CONCLUSIONS

CLE and MIOL implantation improved HRQoL and VRQoL compared to spectacles in this 1-year follow-up study. Improvement of HRQoL was correlated with VRQoL.

Clinical Outcomes After Bilateral Implantation of a Trifocal Presbyopia-Correcting Intraocular Lens in an Indian Population

Purpose

To evaluate the effectiveness and safety of a presbyopia-correcting trifocal intraocular lens (IOL), AcrySof^® IQ PanOptix^® (TFNT00), in an Indian population.

Patients and Methods

This prospective, multicenter, observational, single-arm, post-marketing study included 67 patients undergoing cataract surgery with bilateral implantation of TFNT00 across five Indian sites. Postoperative outcomes were assessed at 3 months after second eye surgery. Effectiveness outcomes included: mean binocular and monocular visual acuity (VA) at distance (4 m), intermediate (60 cm), and near (40 cm); binocular defocus curve; manifest refraction; and subjective symptom questionnaire evaluation. Safety outcomes included the rate of ocular adverse events and mesopic contrast sensitivity.

Results

Mean binocular and monocular distance-corrected and uncorrected VAs of 0.1 logMAR or better (approximately 20/25 Snellen) were achieved at distance, intermediate, and near. Overall, ≥70% of patients achieved binocular 0.1 logMAR vision or better across all distances. TFNT00 maintained a mean VA of 0.1 logMAR or better at the defocus range of +0.5 diopters (D) to –2.5 D (200 cm to 40 cm). The subjective symptom questionnaire-assessed frequency of halo visual disturbances was low at Month 3; halos were reported “none of the time” to “only some of the time” in 86.6% of patients. The large majority of patients (98.5%) were “satisfied” or “very satisfied” with their near, intermediate, and distance vision at Month 3, and ≥94.0% of patients reported spectacle independence for tasks at all distances. The adverse event rate was low; no patients discontinued due to an adverse event.

Conclusion

TFNT00 provided a continuous range of vision of 20/25 or better for distance to near and performed effectively at an intermediate functional distance of 60 cm, resulting in high levels of spectacle independence and patient satisfaction. TFNT00 demonstrated a good safety profile and a low post-operative frequency of halo visual disturbances.

The impact of visual axis position on the optical quality after implantation of multifocal intraocular lenses with different asphericity values

PURPOSE

To evaluate the effect of visual axis positioning on the optical performance of the Tecnis MIOL and the Diff-aA MIOL.

METHODS

In this prospective, randomized comparative study, 70 eyes of 35 subjects with senile cataract were implanted with the spherical aberration-correcting diffractive, bifocal Tecnis ZLB00 IOL and 60 eyes of 30 age-matched subjects with the spherical aberration neutral, diffractive, bifocal Diffractiva IOL. Observation procedure was performed 1, 3, and 6 months postoperatively. Main outcome measures included uncorrected and corrected distance and near visual acuity, manifest refraction, ocular aberrations, and visual quality metrics with 2 mm and 4 mm pupil and the position of visual axis.

RESULTS

At the 6-month visit, no significant difference was found in monocular and binocular uncorrected (UDVA) and corrected (CDVA) distance and near (UNVA, CNVA) visual acuity between the groups. Spherical and coma-like aberrations were similar measured with a 2-mm pupil, but with a 4-mm pupil, the SA was significantly larger (in negative direction) in the Diffractiva group. The higher-order Strehl ratio and MTF was significantly larger in the Diffractiva group measured at 2 mm entrance pupil; however, this difference disappeared by the 4-mm pupil measurements. Postoperative angle alpha distance had a significant influence on HO Strehl value.

CONCLUSIONS

The size of angle alpha is a predictive factor of image quality by multifocal IOL patients.

Multifocal acceptance score to evaluate vision: MAS-2EV

We present a new metric (Multifocal Acceptance Score, MAS-2EV) to evaluate vision with presbyopic corrections. The MAS-2EV is based on a set of images representing natural visual scenes at day and night conditions projected in far and near displays, and a near stereo target. Subjects view and score the images through different binocular corrections (monofocal corrections at far; bifocal corrections; monovision and modified monovision) administered with soft contact lenses (in cyclopleged young subjects) or with a binocular simultaneous vision simulator (in presbyopic and cyclopleged young subjects). MAS-2EV scores are visually represented in the form of polygons, and quantified using different metrics: overall visual quality, visual degradation at far, visual benefit at near, near stereo benefit, visual imbalance near-far, overall visual imbalance and a combined overall performance metric. We have found that the MAS-2EV has sufficient repeatability and sensitivity to allow differentiation across corrections with only two repetitions, and the duration of the psychophysical task (3 min for subject/condition/correction) makes it useable in the clinic. We found that in most subjects binocular bifocal corrections produce the lowest visual imbalance, and the highest near stereo benefit. 46.67% of the subjects ranked binocular bifocal corrections first, and 46.67% of the subjects ranked monovision first. MAS-2EV, particularly in combination with visual simulators, can be applied to select prospective presbyopic corrections in patients prior to contact lens fitting or intraocular lens implantation.

[Quality of life of patients after phacoemulsification with implantation of trifocal intraocular lens]

Studying the quality of life (QoL) of patients after multifocal intraocular correction is a relevant problem in the context of intensive development of cataract and presbyopia surgery.

PURPOSE

To study the QoL of patients with trifocal and monofocal intraocular lenses 1 year after cataract surgery.

MATERIAL AND METHODS

The study included 44 patients divided into two groups: in group 1 - after bilateral implantation of trifocal intraocular lenses, in group 2 - after bilateral implantation of monofocal intraocular lenses. The quality of life of patients in these groups was studied using the VF-14 questionnaire. Additionally, the NAVQ-10 questionnaire was used to study the QoL depending on near vision, satisfaction with the surgery outcome, and the presence and frequency of dysphotopsias.

RESULTS

The quality of life of the patients with trifocal intraocular lenses is significantly higher than with monofocal intraocular lenses according to the VF-14 questionnaire (92.61±7.57 in group 1 and 60.96±3.99 in group 2, p<0.001). Using the NAVQ-10 questionnaire, 68.1% of patients with trifocal lenses were found to have no problems with near vision, 82% of them had high satisfaction with the operation result. 4.5% of patients had intensive dysphotopsias in the dark, 41.0% of patients reported light haloes around light sources during the dark hours and night-time, and 54.5% have not reported any dysphotopsias.

CONCLUSION

Trifocal intraocular lenses ensure higher quality of life for patients after phacoemulsification when compared with monofocal lenses. Dysphotopsias have some effect on the QoL of patients with multifocal correction, but 82% of them are highly satisfied with the surgery outcome.

Catquest-9SF functioning over a decade - a study from the Swedish National Cataract Register

Background

The Swedish National Cataract Register (NCR) collects data on cataract surgery outcomes during March, including patient-reported outcomes using the Catquest-9SF questionnaire for over 11 years. Previous studies from NCR have shown that the preoperative visual acuity has improved over time. The main purpose of this study was to evaluate the Catquest-9SF Rasch scoring performance in this changing environment. A second purpose was to describe clinical data over the same period for those who completed the questionnaire.

Methods

The performance of the Catquest-9SF was analysed by a separate Rasch analysis for each year, resulting in a preoperative and postoperative score for each participating patient in the annual cohorts. The clinical data and questionnaire scoring were analysed for each year in the period 2008–2018 inclusive.

Results

Data were available for 42,023 eyes for 11 annual cohorts (2008–2018). The psychometric properties of the questionnaire were stable during the study period. Person separation (precision) for the whole period was 2.58 and varied between 2.45 and 2.72. The person reliability was 0.87 and varied between 0.86 and 0.88. The targeting of question difficulty to person ability became less accurate over time meaning that the item activities became easier to carry out without difficulty. The average targeting for the whole period was −2.06 and changed from −1.92 in 2008 to −2.31 in 2018. The person score improved both before surgery and after surgery, indicating that patients are undergoing surgery at a more able level and getting better outcomes. The average improvement by surgery decreased from 3.41 logits in 2008 to 3.21 logits in 2018 (p = 0.003).

Over time, patient age decreased from 75 to 74 years (p < 0.001) and the proportion of women decreased from 63.9 to 57.9% (p < 0.001). The mean preoperative visual acuity in both the operated eye and the better eye improved over time (0.47 to 0.40 logMAR, p < 0.001 and 0.22 to 0.19 logMAR, p < 0.001, respectively), as did the mean postoperative visual acuity in the operated eye (0.14 to 0.09 logMAR, p < 0.001).

Conclusions

The Catquest-9SF retained stable psychometric properties over this 11-year period although more recent cohorts included slightly younger patients with somewhat better vision.

Comparison of Post-Cataract Surgery Visual Outcomes and Quality of Life in Patients Bilaterally Implanted with Multifocal Intraocular Lenses

Introduction

The present study compared visual outcomes in eyes with bilateral implantation of two multifocal intraocular lenses (MFIOLs)—the Eyecryl™ ACTV diffractive multifocal IOL (group 1) and AcrySof^® IQ ReSTOR^® multifocal IOL (group 2).

Methods

This was a prospective, two-group observational longitudinal study of 118 eyes from 59 patients conducted at Laxmi Eye Institute, Panvel, India. We evaluated the patients at 1, 3, and 6 months. We assessed visual acuity, contrast sensitivity, higher-order aberrations, reading speed, defocus curve, stereopsis, quality of life (QOL), and adverse events in these participants.

Results

The median (interquartile range) best-corrected distance visual acuity was 0.18 (0, 0.18) in group 1 and 0.18 (0, 0.18) in group 2 at 1, 3, and 6 months; the difference was not statistically significant (p = 0.48). The binocular defocus curve in both groups showed two peaks at 0.0 to −0.5 D and at −2.5 D. The mean (95% confidence interval) critical print size was significantly different between groups 1 and 2 at low illumination (0.918 [0.905, 0.931] vs 1.154 [1.128, 1.180]; p = 0.004). Contrast sensitivity was significantly better in group 1 under mesopic conditions but not under scotopic conditions. Though total QOL did not differ significantly between groups, the psychosocial quality of life was significantly better in group 1. About 23% of patients in group 2 reported unwanted images, compared with 0% in group 1 (p = 0.01).

Conclusion

We found that the Eyecryl and AcrySof groups were comparable for best-corrected visual acuity, photopic contrast sensitivity, defocus curve, reading parameters, stereopsis, and quality of vision. However, the Eyecryl group had better mesopic contrast and a lower proportion of unwanted images. Psychosocial quality of life was significantly better in the Eyecryl group; however, satisfaction was similar between groups. The cost of one of the lenses is less than the other. Thus, individuals with limited resources may opt for the Eyecryl™ ACTV, with similar visual outcomes.

Risk of falls and injuries requiring hospitalisation after first-eye cataract surgery in elderly Australians

PURPOSE

To investigate the impact of the type of the intraocular lenses (IOLs) in first-eye cataract surgery in elderly people on the risk of hospitalisation due to falls and injuries.

METHODS

A retrospective cohort study was conducted using the Australian Government Department Veterans' Affairs claims data. All people aged 65 years and above who had first cataract surgery between January 2007 and July 2017 were identified. Two cohorts were established depending on the type of IOL-monofocal and multifocal. The risk of injuries and falls requiring hospitalisation in the first 3 months post the surgery was assessed using Cox proportional hazard models with age at entry as primary time scale and adjusting for gender, comorbidities and prior history of falls.

RESULTS

There were 45 728 people across the two cohorts with the majority receiving monofocal lenses (97%), followed by multifocal lenses (3%) at the time of first cataract surgery. The risk of injury and falls was lower (but not significant) in the multifocal cohort compared to monofocal cohort (adjusted hazard ratio (aHR) 0.56, 95% CI 0.26-1.17). The risk was also lower (but not significant) when stratifying by age group at the time of the surgery.

CONCLUSIONS

Regardless of age, multifocal lenses did not appear to be associated with the higher risk of serious injuries and falls after first-eye cataract surgery compared to monofocal lenses.

Extended Depth-of-Field Intraocular Lenses: An Update

Extended depth-of-focus (EDOF) is a new intraocular lens (IOL) technology in the treatment of presbyopia. In contrast to multifocal (MF) IOLs, EDOF lenses create a single elongated focal point, rather than several foci, to enhance depth of focus. In this way, EDOF IOLs aim to reduce photic phenomena, glare, and halos, which have been reported in MF IOLs. A potential disadvantage is a decrease of retinal image quality if the amount of the aberrations is excessively increased. Frequently, EDOF IOLs are combined with MF optical designs; for this reason, EDOF IOLs are commonly a subject of confusion with optical multifocality concepts. The aim of this article is to clarify what an EDOF IOL is and to discuss the recently reported outcomes with these IOLs. We propose naming lenses that have combined optical designs as "hybrid IOLs."

Multifocal intraocular lenses and retinal diseases

Purpose

Multifocal intraocular lenses (MIOLs) are often discouraged in patients with or at risk of retinal disorders (including diabetic retinopathy, age-related macular degeneration, and epiretinal membranes), as MIOLs are believed to reduce contrast sensitivity (CS). Concerns with MIOLs have also been raised in individuals with visual field defects, fixation instability or eccentric preferred retinal locations. The aim of this study is to review the influence of MIOL on quality of vision in patients with retinal diseases.

Methods

We reviewed the PubMed and Web of Science databases to identify relevant studies using the following keywords: multifocal intraocular lens, cataract surgery, cataract extraction, lens exchange, diabetic retinopathy, age-related macular degeneration, and contrast sensitivity.

Results

Studies evaluating CS in MIOLs present conflicting results: MIOLs either did not influence CS or resulted in worse performance under low-illuminance conditions and higher spatial frequencies when compared to monofocal IOLs. Nevertheless, MIOLs preserved CS levels within the age-matched normal range. Two studies reported that patients with concurrent retinal diseases receiving a MIOL, both unilaterally and bilaterally, reported a significant improvement in visual-related outcomes. Individuals with a monofocal IOL in one eye and a MIOL in the fellow eye reported greater subjective satisfaction with the MIOL.

Conclusion

We were unable to find evidence suggesting that patients with retinal diseases should be advised against MIOLs. Nevertheless, more research is needed to address the aforementioned concerns and to optimize the use of MIOLs in eyes with retinal disease.
