Abstract
Purpose This study assessed post-market clinical outcomes of the Clareon monofocal intraocular lens (IOL) preloaded in the AutonoMe Delivery System in a real-world setting of Korean patients. Methods This prospective, multicenter, single-arm study in Korea was conducted from July 2020 to December 2021. Patients were ≥20 years old with unilateral or bilateral cataracts who received Clareon IOLs (CNA0T0) preloaded in an automated injector system. Best corrected distance visual acuity (BCDVA) and uncorrected distance visual acuity (UCDVA) were evaluated under photopic conditions. Surgeon delivery system preference was assessed using a survey questionnaire. Glistenings, surface haze, adverse events, posterior capsule opacification (PCO), and Nd:YAG capsulotomy rates were also assessed during the 12-month postoperative follow-up. Results Mean ± SD monocular BCDVA was 0.02 ± 0.11 and 0.00 ± 0.10 logMAR at 1 month and 12 months, respectively. BCDVA of 0.2 logMAR or better was achieved by 94.4% and 99.1% of eyes at 1 month and 12 months after implantation, respectively. Mean monocular UCDVA was 0.11 ± 0.14 and 0.07 ± 0.13 logMAR at 1 month and 12 months, respectively. UCDVA of 0.3 logMAR or better was achieved by 97.4% of eyes at 12 months after implantation. Preparation of the automated injector system was rated as "very easy" or "easy" and CNA0T0 IOL delivery was rated as "very controllable" or "controllable" by all surgeons. Only grade 0 glistenings and no surface haze were observed during the 12-month follow-up. No clinically significant PCO or Nd:YAG capsulotomy were reported throughout the study; clinically nonsignificant PCO was reported in 23% of eyes. Conclusion This 12-month real-world study of the CNA0T0 IOL and the automated injector system demonstrated excellent visual outcomes and high surgeon satisfaction.

Abstract
Purpose To determine the refractive stability of a new hydrophobic acrylic intraocular lens (IOL) when implanted bilaterally. Methods This was a prospective, evaluator masked, single surgeon study of 58 eyes of 29 patients. Patients were bilaterally implanted with the Clareon monofocal IOL (CNA0T0, Alcon Vision LLC). Refractive stability was evaluated between 1 and 3 months postoperatively. At 3 months postoperatively, data were also collected for binocular uncorrected and distance corrected visual acuities at distance (4 m) and intermediate (80 cm and 66 cm) and binocular defocus curve. Results Postoperative refraction was statistically equivalent between 1 and 3 months postoperatively (p < 0.001). Mean postoperative uncorrected distance visual acuity was -0.01 ± 0.10 logMAR, and mean corrected distance visual acuity was -0.04 ± 0.06 logMAR. Mean postoperative uncorrected intermediate visual acuity was 0.16 ± 0.13 logMAR and 0.24 ± 0.14 logMAR at 80 cm and 66 cm, respectively. With distance correction in place, mean visual acuity at 80cm and 60cm was 0.16 ± 0.13 logMAR and 0.23 ± 0.14 logMAR, respectively. Conclusion The Clareon monofocal IOL can provide stable refraction, excellent distance vision, and functional intermediate vision postoperatively.

Abstract
PURPOSE To present the results of a study investigating the 3-year effectiveness and safety of the Clareon single-piece intraocular lens (IOL). SETTING 19 multinational sites. DESIGN Prospective multicenter single-arm study. METHODS Patients were bilaterally implanted with Clareon IOLs. Assessments included uncorrected distance visual acuity, corrected distance visual acuity (CDVA), manifest refraction, tilt, decentration, applanation tonometry, and fundus examination, including glistenings and posterior capsule opacification (PCO) evaluation. The primary outcomes for effectiveness and safety were evaluated at 1 year and compared with ISO historical safety and performance endpoint (SPE) rates. Patients were followed for up to 3 years after implantation. RESULTS 424 eyes of 215 patients were implanted (n = 215 first eye, n = 209 second eye), and 183 patients completed the trial at 3 years (with 364 binocular and 1 monocular patient). At 1 year, the cumulative and persistent adverse event rates were below SPE targets, and 99.5% of eyes achieved a monocular CDVA of ≤0.3 logMAR (vs the SPE target of 92.5%). At 3 years, the mean monocular CDVA was -0.032, with 93.4% (341/365) of eyes achieving a CDVA of 0.1 logMAR or better, 100% of eyes presented with grade 0 glistenings ≤25 MV/mm 2 , and 92.9% of eyes (394/424) had either no PCO or clinically nonsignificant PCO. CONCLUSIONS This study supports the long-term safety and effectiveness of the Clareon IOL. The visual outcomes were excellent and stable over the 3-year study period, PCO rates were very low, and 100% of IOLs had grade 0 glistenings.

Abstract
CLINICAL RELEVANCE It is important to distinguish between visual acuity, optical quality and quality of vision when outcomes obtained with intraocular lenses are evaluated. These parameters, that includeobjective and subjective tests, should be assessed to obtain results that are not biased. BACKGROUND To assess the difference in visual and optical quality between two monofocal intraocular lens models. METHODS : This was a prospective, parallel and randomised clinical study conducted at Miranza IOA, a private clinic in Madrid, Spain. Sixty patients were implanted bilaterally, 30 per group, with two aspheric IOLs with induced spherical aberration of -0.27 μm for Group A and -0.20 μm for Group B. Visual outcomes obtained at 1 and 3 months after surgery included both uncorrected (UCVA) and corrected monocular distance visual acuity (DCVA), objective scattering index (OSI), modulation transfer function (MTF) cut-off, Strehl Ratio (SR), contrast sensitivity defocus curve (CSDC), intraocular lens spherical aberration (SA), and longitudinal chromatic aberration of the eye. Activity limitations in daily life were assessed using CatQuest-9SF questionnaire. RESULTS There were statistically significant differences for DCVA (0.04 LogMAR; p = .008) and SR (0.03; p = .003) between groups. Outcomes related to CSDC showed statistically significant differences for vergences between -0.50 D and +1.00 D (3 mm pupil) and for vergences of 0.00 D and +0.50 D (4.5 mm pupil) between groups. Overall, Group A showed better results regarding visual and optical quality, including a lower longitudinal chromatic aberration result in comparison to Group B. Patient satisfaction evaluated with CatQuest-9SF showed that Group A achieved better outcomes, although the differences were statistically significant only for the 'Reading text on television' item (p = 0.027). CONCLUSIONS Both intraocular lens models showed excellent quantity of vision, optical and visual quality as well as high patient satisfaction. Despite this, the the Group A model provided slightly better outcomes than the Group B model.

Abstract
Purpose To assess real-world clinical outcomes and safety of the Clareon® intraocular lens (IOL) and AutonoMe® automated preloaded delivery system in an Indian population. Patients and methods This was a prospective, single-arm, multicenter, 12-month clinical study in patients aged ≥20 years with unilateral or bilateral cataracts. Surgery was performed by phacoemulsification followed by implantation of the Clareon monofocal IOL (CNA0T0). Monocular best-corrected distance visual acuity (BCDVA) and uncorrected distance visual acuity (UCDVA) were assessed at 1 week and 1, 6, and 12 months after implantation. Posterior capsular opacification (PCO), surface haze, and glistenings were evaluated at all visits. Surgeons' satisfaction with automated injector system was also evaluated using a questionnaire. Safety was assessed by monitoring adverse events (AEs). Results A total of 151 eyes received the CNA0T0 IOL. Mean ± SD monocular BCDVA improved from 0.53±0.44 logMAR preoperatively to 0.00±0.08 logMAR at week 1 and -0.03±0.08 logMAR at 12 months after implantation. At 12 months, 137/137 (100%) of eyes achieved BCDVA of 0.3 logMAR or better. Mean ± SD monocular UCDVA was 0.78±0.40 logMAR preoperatively, 0.11±0.15 logMAR at week 1, and 0.08±0.13 logMAR at 12 months after implantation. At 12 months, 132/137 (96%) eyes achieved UCDVA of 0.3 logMAR or better. Serious intraoperative AEs were posterior capsule rupture (n=1) and ciliary zonular dehiscence (n=1). Surgeons reported that the automated preloaded device was more intuitive compared with other push- or screw-style preloaded injector systems. None of the eyes in this study presented surface haze; all were graded as 0 glistenings at all visits. No clinically significant PCO or neodymium-doped yttrium aluminum garnet (Nd:YAG) capsulotomies were reported. Conclusion The hydrophobic IOL preloaded in an automated injector system provided good visual and refractive outcomes, as well as no surface haze and grade 0 glistenings. None of the patients required Nd:YAG capsulotomy.

Abstract
Purpose To evaluate a single surgeon's experience with an automated preloaded intraocular lens (IOL) delivery system and a nonpreloaded system. Methods This was a prospective, observational case series. Phacoemulsification was performed under topical anesthesia by creating a temporal clear corneal incision. Patients were consecutively assigned to either the Clareon group (n = 50; the IOL was injected into the capsular bag by using an automated injector system) or the AcrySof group (n = 50; the IOL was injected into the capsular bag by using a conventional injector system). The main outcome measures were ease of implantation, intraoperative complications, postoperative centration, and visual acuity. Results Additional manipulation in the anterior chamber was not required in 38 (74%) eyes in the Clareon group and 41 (82%) eyes in the AcrySof group. However, seven eyes in the Clareon group and one eye in the AcrySof group required trailing haptic dislodgement from the optic. Furthermore, two eyes in the Clareon group and five eyes in the AcrySof group required injector rotation (varying from 10° to 90°) in the wound. Moreover, in two eyes of the Clareon group, the silicon plunger of the injector system crossed over the optic. None of the patients developed iris trauma and PCR during IOL manipulation. All the IOLs were centered in the capsular bag. Conclusion The automated IOL delivery system enables the controlled delivery of an IOL in the capsular bag. The effect of carbon footprints created by plastic generated from the delivery system and the implications of the CO2 cylinder on the environment should be addressed.

PLoS One 2022; 17:e0273431. [PMID: 36040874 PMCID: PMC9426912 DOI: 10.1371/journal.pone.0273431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Accepted: 08/08/2022] [Indexed: 11/18/2022] Open
Abstract
Purpose
To compare the change in intraocular lens (IOL) axial movement, corneal power, and postoperative refraction of eyes implanted with two different single-piece, open loop, acrylic foldable IOLs with planar-haptic design: one IOL with hinges vs. one IOL without hinges. The role of IOL axial movement on short-term refractive shift after cataract surgery was also evaluated.
Methods
This retrospective comparative study enrolled consecutive patients who had phacoemulsification with aspheric IOL implantation. The IOL depth (the distance from corneal endothelium to IOL surface) and corneal power were measured via anterior-segment optical coherence tomography at 4 days and 1 month postoperatively. The changes in axial movement of the IOL, corneal power, and manifest refractive spherical equivalent (MRSE) were compared among groups, and the correlations between each lens were evaluated.
Results
IOL with hinges was implanted in 42 eyes of 42 patients and IOL without hinges was implanted in 42 eyes of 42 patients. The change in axial movement between 4 days and 1 month was significantly smaller in the IOL with hinges group than in the IOL without hinges group (p < 0.001). The axial movement of IOL with hinges did not correlate with the MRSE change; however, the forward shift of IOL without hinges correlated with the myopic refractive change (Pearson r = 0.62, p < 0.001).
Conclusion
The postoperative axial movement of IOL was more stable in the IOL with hinges group than the IOL without hinges group between 4 days and 1 month after cataract surgery. Even though the two study IOLs with planar-haptic design are made of similar acrylic materials, other characteristics such as hinge structure may affect IOL stability in the bag.

Abstract
PURPOSE To assess a single-piece monofocal hydrophobic acrylic intraocular lens (IOL) with hydroxyethyl methacrylate (HEMA) (Clareon) contained in automated preloaded delivery system (AutonoMe). SETTING 18 surgical sites in Japan. DESIGN Observational study. METHODS In patients undergoing phacoemulsification and IOL implantation of a new hydrophobic acrylic IOL using an automated injector, clinical data were collected preoperatively and at 1 day, 1 week, and 1 month, 6 months, and 12 months postoperatively. The degree of glistenings was graded on a 4-point scale. The surgeons rated usability and performance of the IOL delivery system on a 5-point scale. RESULTS The study enrolled 384 eyes of 384 patients, ranging in age from 41 to 93 (73.8 ± 8.2, mean ± SD) years. The percentage of eyes with corrected distance visual acuity of 20/25 or better at 1 day, 1 week, and 1 month, 6 months, and 12 months postoperatively was 82.6%, 91.9%, 92.8%, 96.6%, and 95.2%, respectively. Refractive error was within 1.0 diopter in approximately 90% of cases. No glistenings were found in all cases throughout the study period. The rate of Nd:YAG laser posterior capsulotomy was 0.9% at 1 year. The IOL delivery system received high ratings on its usability and performance by the surgeons. CONCLUSIONS The new hydrophobic acrylic IOL with HEMA showed excellent visual and refractive outcomes without developing glistenings throughout the 1-year study period. The surgeons gave high marks for usability and performance of the automated preloaded delivery system.

Abstract
Purpose To evaluate transient hyperopic refractive outcomes after Acrysof IQ Panoptix TFNT intraocular lens (IOL) implantation and risk factors for transient hyperopia. Methods This was a retrospective case review conducted from July 5, 2019, to February 28, 2020, of 203 eyes from 203 patients. The spherical equivalent (SE) on postoperative day 1, week 1, month 1, month 2, and month 6 was evaluated, and the difference between SE (dSE) on postoperative day 1 and month 6 was calculated. Ocular parameters that were associated with a high dSE were evaluated. Results This study evaluated 203 eyes from 203 patients (mean age ± SD, 59.14 ± 5.78 years; 129 women [63.5%]). The dSE ± SD was 0.07 ± 0.30 D, 0.14 ± 0.34 D, 0.12 ± 0.35 D, and 0.08 ± 0.35 D for postoperative week 1, month 1, month 2, and month 6, respectively. Univariate analysis revealed that the anterior chamber depth and white-to-white (WTW) corneal diameter were associated with a larger dSE (P = 0.048 and P = 0.03, respectively). Multivariate analysis showed that the WTW diameter was independently associated with the large amount of dSE at 6 months (r = -0.162; P = 0.03). Conclusion The results of this study suggest that a smaller WTW corneal diameter was associated with a large dSE between postoperative day 1 and postoperative month 6.

There were 4 groups (10 eyes per group) with different incision site and size: 2.2-mm and 2.4-mm corneal incisions and 2.2-mm and 2.4-mm sclerocorneal incisions. Delivery performance and wound enlargement of AutonoMe were analyzed and compared with those of iTec and iSert from a previous study. Results There were a few minor troubles associated with AutonoMe, such as overriding plunger within cartridge and trapped trailing haptic during IOL insertion, but the incidence was low. Other interactions were not observed, such as IOL adherence to plunger, sudden ejection of IOL, intrawound lens manipulation, IOL behavior, and gross damage to IOL. AutonoMe caused significantly less wound enlargement for both corneal and sclerocorneal incisions than other injector devices. Wound enlargement by using AutonoMe was significantly smaller with 2.4-mm corneal incision than with 2.2-mm corneal incision, but the final incision size was still smaller with 2.2-mm corneal incision. For sclerocorneal incisions, the amount of wound stretch was not different between 2.2 and 2.4 mm incisions. Conclusion The wound enlargement caused by the automated preloaded insertion system, AutonoMe, was smaller than that of other preloaded injectors for both corneal and sclerocorneal incisions. There were a few minor technical events during IOL insertion, but the overall incidence was low.
