“…Intermediate vision is a hot topic in ophthalmology as people increasingly use technological devices. 10 Our study showed advantage of LuxSmart regarding uncorrected and distance-corrected intermediate visual acuity as shown by the smooth transition between distance and intermediate vision in defocus curve. EDOF IOLs have previously proved to achieve better intermediate vision than monofocal and trifocal IOLs.…”

Purpose To assess the preliminary clinical outcomes and patient satisfaction of the new enhanced depth of focus (EDOF) LuxSmart™ intraocular lens IOL and to compare with a conventional monofocal IOL (Akreos™) in patients who had undergone bilateral cataract surgery. Methods Twelve patients underwent bilateral LuxSmart IOL implantation, and twelve underwent bilateral Akreos IOL implantation. Best-corrected distance (CDVA) and uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) at 66cm, uncorrected near visual acuity (UNVA) at 40cm and defocus curve were assessed. Patients-reported visual function was inquired by Catquest-9SF. The presence of photic phenomena was evaluated. A p-value lower than 0.05 was considered for statistical significance. Results The mean IOL power was +21.90D in LuxSmart group and +22.30D in Akreos. Monocular UDVA (p = 0.32) and CDVA (p = 0.52) did not differ between groups. The average binocular UIVA (0.18 ± 0.12 logMAR vs. 0.30 ± 0.13 logMAR, p < 0.001) and UNVA (0.38 ± 0.14 logMAR vs. 0.44 ± 0.17 logMAR, p = 0.02) were higher in LuxSmart IOL group. No patients reported disabling photic phenomena in either group. Conclusion This study shows that new LuxSmart EDOF IOL achieved higher performance for intermediate and near vision compared with a conventional monofocal IOL, without increasing the risk of dysphotopsias. LuxSmart may be an attractive and safe option for patients who desire spectacle independence for distance and intermediate vision after cataract surgery.

“…Advances in cataract surgery and refractive lens exchange have enabled these techniques to be used to achieve precise and desired refractive outcomes [1]. This has raised patients' expectations of excellent uncorrected distance visual acuity [2].…”

“…However, with monofocal intraocular lenses (IOLs), the desire for freedom from spectacles cannot be completely met. Multifocal intraocular lenses (MIOLs) are used more commonly and to a considerable extent for refractive purposes in non-cataractous eyes [3]. It is believed that as MIOLs decrease contrast sensitivity, so they are advised against in patients with retinal disorders.…”

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.

“…2 Conventional phacoemulsification and intraocular lens (IOL) implantation are the most common cataract surgery procedures performed, with over 20 million interventions executed each year globally. 3 Phacoemulsification is a mechanically assisted extracapsular technique of cataract extraction in which a corneal incision at the temporal site is made to allow the introduction of an ultrasound probe to emulsify the cataractous lens and replace it with an IOL. 4 Intrinsic factors of the procedure such as the toxic effects of preservatives used during and after the surgery, repeated intraoperative ocular surface drying, or phototoxicity effects of the operating microscope light might damage the ocular surface to different extents.…”
