Summary: In this experiment, four different intraocular lens (IOL) models were compared to evaluate their optical performance. The results showed that all the extended depth-of-focus (EDoF) IOL models had an extended range of focus, with the non-diffractive AcrySof IQ Vivity demonstrating a smoother transition compared to the diffractive models. The study also raised the question of potential increased visual disturbances with the diffractive designs.

Summary: Research on the mechanism of cortical cataract formation found that stretching leads to an increase in equatorial diameter in ex vivo lenses, but central thickness does not change significantly. Ruptures at the nucleus-cortex interface were observed in lenses with cortical cataracts, suggesting they may occur during accommodation or attempted accommodation.

Summary: In recent years, there has been a surge in the availability of different types of intraocular lenses (IOLs) for treating presbyopia. Extended depth-of-focus (EDOF) lenses aim to enhance the depth of focus and reduce visual disturbances like glare and halos. However, excessive aberrations can lead to decreased retinal image quality and blur. EDOF characteristics can be combined with multifocality or other optical designs, leading to confusion in the market. This article provides clarification on true EDOF lenses, categorizes different types based on optical principles, and reviews recent outcomes.

Summary: The purpose of this study was to compare the postoperative outcomes, spectacle dependence, and occurrence of photic phenomena in patients after cataract surgery with a non-diffractive extended depth of focus (EDOF) intraocular lens, monofocal lenses, and multifocal lenses. The results showed that EDOF lenses improved visual acuity at any distance after 6 months, with better contrast sensitivity compared to multifocal lenses and the best monocular visual acuity for near distance provided by multifocal lenses. EDOF lenses significantly reduced dependence on glasses compared to monofocal lenses, while multifocal lenses provided the greatest independence from glasses. The incidence of photic phenomena was higher for multifocal lenses than for monofocal lenses.

Summary: There are currently three different strategies for pharmacological treatment of presbyopia: inducing miosis to improve near visual acuity, restoring lens elasticity lost due to aging, and rehabilitating accommodation for good vision at all distances. These treatments, involving eyedrops with varying compositions, are a new alternative expanding the diversity of existing strategies and are expected to be on the market in the near future. Proper patient selection is crucial for the successful use of any of these three strategies.

Summary: The purpose of this retrospective study was to compare the visual performance and optical quality among three different enhanced monofocal intraocular lenses (IOLs). The study included patients with cataracts and corneal astigmatism less than 0.75 D, who underwent cataract surgery with bilateral implantation of Tecnis Eyhance ICB00, Vivinex Impress XY1-EM, or IsoPure 123 IOLs. Three months after the surgery, various visual parameters were evaluated and compared, including visual acuity, contrast sensitivity, and intraocular aberrations. The results showed no significant differences between the three groups.

Summary: This study assessed the depth of focus of four latest non-diffractive extended range of vision intraocular lenses (IOLs) on the optical bench. The results showed that Eyhance and RayOne EMV had the most pronounced MTF peak at 3mm aperture, but with little enlarged depth of power. Vivity and LuxSmart had depths of focus of about 1.7D and 1.3D respectively, but with reduced MTF and differently located maxima. At 4.5mm aperture, MTF values dropped for Eyhance and particularly for RayOne EMV, while only the peak for the secondary focus decreased for Vivity and LuxSmart.

Summary: Presbyopia is a common eye disorder in aged people, caused by the stiffening of the crystalline lens. One potential technique to correct presbyopia involves replacing the lens substance with an artificial lens. The development of devices like accommodating intraocular lenses relies on understanding the biomechanical behavior of the lens capsule and design verification. Mimicking the eye's dynamic focusing ability, an artificial lens capsule made from silicone rubber and a lens radial stretching system were developed to address the biomechanical function of the ALC. Initial tests on ophthalmic devices prototypes have shown promising results in restoring accommodation.

Summary: This study examined the effects of long-term ultraviolet radiation (UVR) blocking wearing contact lenses on ocular surface health, eye focus, and macular pigment. The results showed that wearing UVR-blocking contact lenses can protect ocular health, delay the occurrence of presbyopia, and improve the adaptability of eye focus.

Summary: Cataract surgery has evolved into a refractive procedure using extended depth-of-focus or multifocal intraocular lenses (IOLs) to restore vision beyond the far distance. Factors such as corneal astigmatism, tolerance of IOLs, economic aspects, comorbidities, and efficacy of astigmatism treatment can affect the selection of lens implantation for each patient. This review aims to summarize current evidence on low astigmatism tolerance in presbyopia-correcting lenses, the efficacy achieved through corneal incisions, and their comparison with toric IOL implantation.

Summary: Studies have shown that presbyopia-correcting IOLs can provide satisfactory results for postkeratorefractive patients. However, there is a lack of research on how preoperative measures affect outcomes. Therefore, continued investigation into relevant preoperative factors and suitable IOLs is necessary to make evidence-based decisions.

Summary: This study investigates the perception and adoption of myopia control strategies among African eye care practitioners. The results indicate that African eye care practitioners continue to predominantly prescribe single vision spectacles instead of other myopia control modalities, and their perception of the efficacy of these modalities does not align with the current best evidence. Clear practice guidelines and continuing education are needed to improve the management of myopic patients in Africa.

Summary: This study reports on the results of a survey conducted in Spain in 2019, comparing them with results from other regions worldwide. The survey found that Spain, Asia, and South America had the highest concern about the increasing incidence of myopia. However, single-vision spectacles and contact lenses were still the main methods of visual correction prescribed to young myopic patients in these regions. Spanish practitioners, like those from other regions, considered orthokeratology as the most effective treatment for myopia control. The main reasons why Spanish practitioners did not prescribe myopia control strategies were increased cost, inadequate information, and unpredictable outcomes.

Summary: Presbyopia refers to the reduction in the eyes focusing range due to age, causing insufficient clarity of vision at near even with optimal correction for distance vision. It has a significant impact on an individual's quality of life and emotional state. Access to amelioration strategies is often limited, and prescribing practices are not optimal. This review emphasizes the need for a standardized definition of presbyopia, appropriate testing in evaluating management options, and publication of clinical trial results to improve outcomes for presbyopes.

Summary: Artificial tears are important for managing dry eye disease and have various applications. Regular use of artificial tears can improve symptoms within a month, while signs may take longer to improve. Not all patients benefit from artificial tears, and alternative management should be considered if there is no improvement after a month. Combination formulations and artificial tears containing polyethylene glycol are more effective, and liposomal artificial tears with higher concentration are beneficial for patients with evaporative dry eye disease.

Summary: To find the solution for the average paraxial lens power of a lens, a paraxial representation of lens power was obtained through integration. Visual acuity was measured using lenses of different powers and axes, and it was found that correction with -A(p)P provided better visual acuity than MSE for central viewing. These findings suggest that F/4 may be a more inclusive representation of the average paraxial power of a cylindrical lens.

Summary: Surveys in 2015 and 2019 showed that there was a high level of concern and activity about myopia among eye care practitioners, but most of them still prescribed single vision interventions for young myopes. This research aimed to provide updated information on this topic. The results showed that practitioners in Asia had a significantly higher level of concern about pediatric myopia compared to other continents. Combination therapy was perceived as the most effective method of myopia control, followed by orthokeratology and pharmaceutical approaches, while single vision interventions were seen as the least effective.
