“…Recent publications have reinforced that preloaded monofocal hydrophobic acrylic IOLs provide an opportunity to make cataract surgery quicker, easier, safer, and therefore more economical. A recent observational study involving 200 routine cataract surgeries showed a significantly decreased mean total case time by 7.7–7.8% when using a preloaded monofocal hydrophobic acrylic IOL rather than a manual IOL delivery process [ 17 ]. Preloaded monofocal hydrophobic acrylic IOLs have also performed well in recent studies involving challenging cases of pseudoexfoliation syndrome [ 18 , 19 ].…”

Background This study was designed to evaluate visual, refractive and safety outcomes in eyes after they underwent phacoemulsification and implantation of a preloaded monofocal hydrophobic acrylic intraocular lens. Methods This was a single center observational study conducted at Ashford and St Peter’s Hospitals NHS Foundation Trust, United Kingdom. Patients were included if they had cataract extraction with in-the-bag implantation of the EyeCee® One preloaded intraocular lens from August to October 2019. Pre-operative, surgery-related and 2 weeks and 3 months post-operative data was collected. Surgeons at this trust were then asked to complete a feedback form to evaluate their experience of implanting the EyeCee® One. Results One hundred fifty-two eyes were included in the study. Ninety-four (62%) of these eyes had cataract but no concomitant ocular pathology that could potentially affect visual acuity. Three months post-operatively, 98.7% of all eyes had monocular CDVA ≤0.3 logMAR. 100% of the eyes without concomitant ocular pathology achieved this target. The mean CDVA of all eyes in this study improved from 0.43 ± 0.43 logMAR pre-operatively, to 0.05 ± 0.11 logMAR post-operatively (p < 0.05). The mean sphere and spherical equivalent values showed significant improvements (p < 0.05) and (p < 0.05). There were no intraoperative complications and 1.3% of patients reported complications 2 weeks post-operatively. All of the participating surgeons said they would use the EyeCee® One again with 64% providing an overall rating of ‘excellent’ for their experience of implanting this intraocular lens. Conclusions This study indicates excellent post-operative visual acuity and refractive outcomes in eyes after EyeCee® One implantation. This is accompanied with very little risk of intraoperative and post-operative complications.

“…In contrast with manually loaded IOLs, preloaded delivery systems allow for reduced device preparation time, 9,10 which can significantly shorten total surgical case times and potentially increase efficiency of surgical centers and help meet the increased demand for cataract surgery. 9,[11][12][13] Preloaded delivery systems can also improve the consistency of IOL haptic folding and reduce the risk of IOL damage 9,10,14,15 by eliminating loading variability or user error and reducing the risk of contamination by eliminating the need to handle the IOL. 12,[16][17][18] A prospective, randomized, comparative study reported that the AutonoMe Delivery System provided safe and easy IOL delivery; no haptic misconfigurations were observed.…”

“…5,8 Advancements in the design of IOL delivery systems have improved efficiency and outcomes of cataract surgery, including shorter total surgical case time and reduced risk of loading variability and device contamination. [11][12][13] The automated injector system used in this study is the first preloaded delivery system to use an automated mechanism of action. It provides intuitive ergonomic single-handed control of IOL delivery designed to benefit the surgeon, such that…”

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.
