Visual Outcomes after Bilateral Implantation of an Extended Depth of Focus Intraocular Lens: A Multicenter Study

PurposeTo evaluate visual performance after bilateral implantation of an extended depth of focus (EDOF) intraocular lens (IOL).MethodsThis multicenter, prospective, observational study included 100 patients who underwent bilateral cataract surgery with a toric or non-toric EDOF IOL (Tecnis Symfony), and 96 patients completed the final assessment at 4 to 6 months. Binocular corrected distance visual acuity and uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), and uncorrected near visual acuity (UNVA), spectacle independence, visual symptoms, and patient satisfaction were evaluated.ResultsMean decimal visual acuity results showed a binocular corrected distance visual acuity of 1.10 ± 0.18, UDVA of 1.04 ± 0.17, UIVA of 0.96 ± 0.16, and UNVA of 0.68 ± 0.18. Binocular UDVA and UIVA were 0.8 (decimal) or better in 98% and 94% of patients, respectively. Binocular UNVA was 0.63 (decimal) or better in 76% of patients. Overall, 76% of the patients achieved spectacle independence across all distances, and more than 85% reported no or mild dysphotoptic phenomena. On a scale of 0 to 10, the median patient satisfaction score was 9 for far, 9.5 for intermediate, and 8 for near vision.ConclusionsThe Symfony EDOF IOL provided excellent distance, intermediate visual outcome, and functional near visual acuity. The visual results were associated with prominent levels of spectacle independence and patient satisfaction.

Optical performance after bilateral implantation of apodized aspheric diffractive multifocal intraocular lenses with +3.00‐D addition power

Purpose: To determine whether bilateral implantation of an aspheric apodized diffractive multifocal intraocular lens (IOL) with +3.00 diopters (D) results in optical adverse effects compared with an aspheric monofocal IOL. Methods: In a prospective, randomized study of 204 eyes (102 patients) with bilateral implantation of an AcrySof ReSTOR SN6AD1 IOL or an AcrySof IQ SN60WF IOL, binocular uncorrected (UDVA) and corrected distance visual acuities (CDVA), uncorrected (UIVA) and distance‐corrected intermediate visual acuities (DCIVA), uncorrected (UNVA) and distance‐corrected near visual acuities (DCNVA), defocus curve, intraocular straylight, wavefront aberrations, modulation transfer functions (MTF) and patient questionnaires were evaluated postoperatively. Results: Both groups resulted in similar UDVA and CDVA (p > 0.05), whereas the multifocal IOL group performed significantly better UIVA and DCIVA at 50, 60 cm, and better UNVA and DCNVA at 40 cm (p ≤ 0.001). Higher intraocular straylight was obtained in the multifocal IOL group (p = 0.016). Total, higher‐order, spherical and coma aberrations performed similar in both groups (p > 0.05). MTF was lower in the multifocal IOL group than in the monofocal IOL group with 3.0‐mm pupils at 5 and 10 cycles per degree (cpd). Although patients in the multifocal IOL group complained more glare/flare, problems with night vision, and halos, they reported excellent spectacle independence, and high satisfaction. Conclusions: Compared with the AcrySof IQ IOL, the ReSTOR SN6AD1 IOL provided excellent visual outcomes, satisfactory spectacle independence without compromising wavefront aberrations; however, optical adverse effects with respect to higher intraocular straylight and lower MTF at lower spatial frequency were demonstrated.

Comparison on visual function after implantation of an apodized diffractive aspheric multifocal or monofocal intraocular lens

 Purpose: To evaluate visual outcomes after implantation of an aspheric multifocal/ intraocular lens (MIOL) or an aspheric monofocal intraocular lens (IOL). Methods: This was a prospective nonrandomized study. During 3-months of post-operative follow-up, the following outcomes for SN6AD1 MIOL (multifocal group) and SN60WF IOL (monofocal group) were compared: uncorrected (UDVA) and corrected (CDVA) distance visual acuity, uncorrected (UNVA) and distance-corrected (DCNVA) near visual acuity, Chinese character near visual acuity, uncorrected intermediate visual acuity (UIVA) under high (100% contrast) and low contrast (10% contrast), UIVA for different IOL powers, and a quality-of-life questionnaire. Results: UNVA, DCNVA, and UIVA under high contrast in the multifocal group were significantly better than those in the monofocal group (P＜0.05). UDVA, CDVA and UIVA under low contrast did not differ between groups at 63 cm and 100 cm (P＞0.05). In most of the cases, Chinese character near visual acuity was significantly better in the multifocal group (P＜0.05). UNVA and UIVA at 63cm were improved 3 months post-operatively. Better UIVA was found in emmetropic and mild myopic eyes as compared to hyperopic ones. The patients in the multifocal group had a higher degree of satisfaction and performed better on near and intermediate tasks, although with greater complaints of visual disturbance.    Conclusion: The SN6AD1 MIOL provides significantly better UNVA, DCNVA and UIVA under high contrast conditions, and better Chinese character near visual acuity. Patients receiving the SN6AD1 MIOL reported a better quality of vision in spite of more serious visual disturbances. Better UIVA was observed in emmetropic and mildly myopic eyes.     

Comparison of an aspheric monofocal intraocular lens with the new generation monofocal lens using defocus curve

Purpose:The aim of this study was to compare the visual outcomes of two monofocal intraocular lenses (IOLs), with emphasis on the defocus curve.Methods:A total of 116 consecutive eyes with cataract, undergoing phacoemulsification with IOL implantation were included in the observational case series, and divided into two groups. 71 eyes were implanted with Tecnis Eyhance and 45 with Tecnis 1 monofocal IOL. Eyes with ocular comorbidities, previous ocular surgeries and corneal astigmatism >1 Diopters (D) were excluded from the study. Complete ophthalmic evaluation including uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA), corrected intermediate visual acuity (CIVA), uncorrected visual acuity (UNVA), corrected near visual acuity (CNVA) was noted and defocus levels ranging from - 4.00 D to + 1.00 D were plotted postoperatively in both groups.Results:Uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA) was significantly better in Tecnis Eyhance group compared to Tecnis 1 monofocal. Both the IOLs have similar performance for distance vision but visual acuity at intermediate and near is significantly better with Tecnis Eyhance compared to Tecnis 1 piece IOL.Conclusion:Tecnis Eyhance IOL with its better defocus curve, not only provides good distance, but intermediate vision as well. With significantly better visual acuity across the range of near and intermediate vision, Tecnis Eyhance IOL can prove to be a viable and reasonable option for patients who are more dependent on intermediate vision in daily activities.

Purpose:To evaluate the visual outcomes of bilateral implantation of a new hydrophobic foldable extended depth of focus (EDOF) IOL.Methods:All cases undergoing phacoemulsification with bilateral implantation of Supraphob Infocus IOL between December 2017 and July 2018 at a tertiary eye care center were recruited in this prospective interventional study. The primary outcome measures were uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), and uncorrected near visual acuity (UNVA). Postoperative follow-up was done on day 1, 1 week, 1 month, and 3 months.Results:One hundred and four eyes of 52 patients with a mean age of 58.4 ± 9.3 years were included. The mean UDVA improved from 0.84 ± 0.32 logMAR preoperatively to 0.11 ± 0.08 logMAR at 3 months following surgery. At the final follow-up, the binocular UDVA, UIVA, and UNVA was 0.03 ± 0.07, 0.14 ± 0.06, and 0.36 ± 0.05 logMAR, respectively. The mean CS was 1.47 ± 0.06 logCS. The distance and near stereopsis was 90.2 ± 24.8 s of arc (arcsec) and 62.5 ± 19.4 arcsec, respectively. The mean total higher-order aberration (HOA), point spread function, and modulation transfer function were 0.30 ± 0.13, 0.07 ± 0.08, and 0.26 ± 0.07, respectively.Conclusion:The Supraphob Infocus EDOF IOL provides good unaided visual acuity for distance, intermediate, and near along with a high quality of vision as assessed by contrast sensitivity, HOAs, and stereoacuity. It may be a potential alternative to the currently available EDOF IOLs in providing good visual acuity at variable distances.

方法：采用以人群为基础的横断面研究。以美国国家眼科研究所研制开发的视功能调查问卷(the National Eye Institute Visual Functioning Questionnaire-25,NEI VFQ-25)对研究对象的术后视功能相关生活质量(vision-related quality of life,vision-related QoL)进行评价。收集2017-03/2018-03行白内障超声乳化吸除联合IOL植入术的患者30例60眼,按照植入IOL类型分为两组,双眼植入TECNIS Symfony连续视程人工晶状体(ZXR00)为双眼组(18例36眼),一眼植入TECNIS Symfony连续视程人工晶状体(ZXR00),另一眼植入非球面单焦点IOL(PCB00)为单眼组(12例24眼)。术后3～6mo进行随访,主要观察指标为双眼远、中、近裸眼视力和生活质量调查问卷。

结果：双眼组和单眼组术后双眼裸眼远、中、近视力比较,差异无统计学意义(P>0.05)。两组患者术后NEI VFQ-25问卷总评分(88.95±4.01 vs 88.99±4.22分)比较,差异无统计学意义(t=-0.025,P=0.980)。12个维度的评分结果对比显示,两组患者术后与视觉相关的各个方面生活质量差异均无统计学意义(P>0.05)。

结论：双眼植入ZXR00或一眼植入ZXR00,另一眼植入PCB00的患者均具有良好的双眼全程视力。两组患者的术后生活质量无差异。对一眼已行单焦点IOL植入的患者或一眼不适合装多焦点人工晶状体的患者,可行另一眼Symfony连续视程IOL植入以满足患者脱镜需求。     

A novel standardized test system to evaluate dynamic visual acuity post trifocal or monofocal intraocular lens implantation: a multicenter study

ObjectivesTo compare the dynamic visual acuity (DVA) following implantation of trifocal with monofocal intraocular lenses (IOL) and using a novel test system.MethodsThe present research was a retrospective, multicenter clinical study. Two hundred and ten eyes of 149 patients that underwent cataract phacoemulsification and IOL implantation were enrolled. One hundred and ten eyes of patients received trifocal (AT LISA tri839MP, Carl Zeiss Meditec, Germany) and 100 eyes received monofocal (Tecnis ZCB00, Abbott, United States) lenses and were evaluated 3 months after implantation. Outcome measures included monocular uncorrected distance (UDVA), intermediate (UIVA) and near (UNVA) visual acuity and best corrected distance visual acuity (BCDVA; logMAR units); contrast sensitivity under photopic, mesopic, with glare conditions; and dynamic visual acuity using a self-developed system.ResultsThere was no statistically significant difference in baseline characteristics between groups. Monocular UDVA, UIVA, and UNVA were significantly better (all p < 0.001) in the trifocal IOL group, but not BCDVA. The trifocal IOL group showed better contrast sensitivity under photopic, mesopic, with or without glare conditions (p < 0.05) and statistically significantly better dynamic vision at 15, 30, 60, and 90 degrees per second (dps) compared with the monofocal group (all p < 0.001). The strength of positive association only between UIVA and dynamic visual acuity increased as the velocity increased, but not UDVA or UNVA.ConclusionsDiffractive trifocal IOL provides better postoperative full range vision acuity, contrast sensitivity, and dynamic vision compared with monofocal IOLs. And intermediate visual acuity is increasingly associated with DVA as the velocity increasing.Subject terms: Quality of life, Outcomes research
