Abstract
Presbyopia affects between 1.7 and 2 billion people worldwide. Presbyopia significantly impacts productivity and quality of life in both developed and developing countries. During accommodation, the human eye changes its dioptric power by altering the shape of the lens, but the exact nature of this change has not been fully explained. Recently, topical treatments have been marketed for the treatment of presbyopia and others are under investigation. In order to prepare a review of these novel therapies, we searched the major biomedical search engines. We found 15 randomized clinical trials and 12 reviews that met our review criteria. There are two different strategies for this purpose, the pinhole effect that increases depth of focus and "crystalline lens relaxation" for which parasympathetic mimetics and lens oxidation intermediates have been used. The results are generally favorable in terms of improvement of near visual acuity, although the follow-up period of the studies is short. These are novel strategies in the early stages of research that could be useful in the treatment of presbyopia.

[PMID: 38512509 DOI: 10.1007/s00417-024-06455-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 03/03/2024] [Accepted: 03/16/2024] [Indexed: 03/23/2024] Open
Abstract
PURPOSE To explore the impact of refractive status on presbyopia progression among patients with presbyopia. METHODS This retrospective observational study included patients with presbyopia who visited the Seventh Affiliated Hospital of Sun Yat-sen University and Shenzhen Polytechnic Medical College between May 2018 and August 2022. The amplitude of accommodation (AMP) and near addition power (ADD) at 6 months and 1 year were collected. RESULTS A total of 103 patients with presbyopia were included in this study: 42 patients with myopia, 23 patients with emmetropia, and 38 patients with hyperopia. There were significant differences in ΔAMP(6-month) and ΔADD(6-month) among patients with different refractive statuses, and the values of emmetropic patients and hyperopic patients were higher than in myopic patients (all P < 0.001). The ΔAMP(1-year) and ΔADD(1-year) of hyperopic patients were significantly higher than in emmetropic patients and myopic patients (all P < 0.001). The ΔADD(1-year) of emmetropic patients was greater than in myopic patients (P = 0.045), but there were no significant differences in ΔAMP(1-year) between patients with emmetropia and myopia (P = 0.090). CONCLUSIONS The progression of presbyopia in hyperopic patients was relatively more significant than for emmetropia, followed by myopia. The prescription of presbyopia glasses might need to be replaced more frequently in patients with hyperopia.

Efficacy and Safety of CSF-1 (0.4% Pilocarpine Hydrochloride) in Presbyopia: Pooled Results of the NEAR Phase 3 Randomized, Clinical Trials. Clin Ther 2024; 46:104-113. [PMID: 38216351 DOI: 10.1016/j.clinthera.2023.12.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 12/12/2023] [Accepted: 12/13/2023] [Indexed: 01/14/2024]
Abstract
PURPOSE This study was undertaken to evaluate the safety and efficacy of CSF-1 (0.4% pilocarpine hydrochloride ophthalmic solution) for use in individuals with presbyopia. METHODS Two Phase 3 multicenter, randomized, double-masked, vehicle-controlled, parallel-group clinical trials were conducted in 35 private ophthalmology clinics in the United States from October 2020 to February 2022. Key inclusion criteria were the following: (1) age 45-64 years, (2) distance-corrected near visual acuity (DCNVA) at 40 cm ≥0.40 and ≤0.90 logarithm of the minimum angle of resolution (logMAR, approximately 20/50-20/160 Snellen) in at least 1 eye, (3) manifest refraction (MR) between -4.50 and +2.00 diopter (D) sphere in each eye with ≤2.00D difference between eyes, (4) <2.00D of cylinder MR in each eye, (5) ≤0.04 logMAR (20/20-2 or better) corrected distance visual acuity (CDVA) at 4 m in each eye. Key exclusion criteria were the following: (1) >0.14 logMAR (7 letters) improvement in post-vehicle treatment in monocular DCNVA in either eye at visit 1, (2) introcular pressure (IOP) <9 or >22 mm Hg, (3) average dark-adapted pupillometry <3.5 mm in either eye, (4) prior refractive surgery or intraocular lens (IOL) implantation. Participants applied CSF-1 or vehicle twice per day for 2 weeks. Efficacy and safety assessments were performed at several times on days 1, 8, and 15. Response was defined as ≥3-line gain in DCNVA without loss of ≥1-line in CDVA in the study eye under mesopic room lighting conditions. The primary efficacy endpoint was measured 1 hour post-dose 1 on day 8. Key secondary endpoints were 2 hours post-dose 1, and 1 and 2 hours post-dose 2, also on day 8. Safety endpoints were ocular and non-ocular treatment-related adverse events (TRAE), conjunctival redness, drop comfort, slit-lamp biomicroscopy, intraocular pressure, indirect fundoscopy, and CDVA at 4 m. FINDINGS Six hundred thirteen participants were randomized to CSF-1 (n = 309) or vehicle (n = 304). Participants were predominantly White (80.8%) and female (62.0%), with mean age (standard deviation) of 54.7 (4.8). CSF-1 met the primary and key secondary endpoints. At the primary endpoint, 40.1% of the CSF-1 group achieved response versus 19.1% of the vehicle group (P < 0.0001). The percentage of responders was significantly greater in CSF-1 compared with vehicle at all tested times. Changes from baseline in all safety endpoints were comparable between groups. Most adverse events (AEs) were mild and transient. Neither serious nor severe AEs were reported with CSF-1. IMPLICATIONS CSF-1, a low-dose pilocarpine ophthalmic solution, demonstrated superiority to vehicle in improving near vision in individuals with presbyopia without compromising distance vision. CSF-1 demonstrated a favorable safety profile. CLINICALTRIALS gov identifier: NCT04599933 (NEAR-1), NCT04599972 (NEAR-2).

Abstract
Accommodation is the change in dioptric power of the eye. It is a dynamic process that allows focusing on an object at all distances. In order to focus sharply, three physiological responses, known as the triad of accommodation, are produced by a change in pupil size, a change in shape and position of the lens, and ocular convergence. This is modulated by the autonomic nervous system, mainly the parasympathetic nervous system. Presbyopia is a refractive condition that occurs with aging, usually manifesting around 40-50 years of age, and is a result of the loss of accommodation in the eye, causing loss of visual performance when focusing on objects placed at different distances, starting with near vision. Glasses, contact lenses, surgical approaches and now pharmacological treatments are accepted methods of treating presbyopia. Pharmacological treatment is a promising new noninvasive option for treating presbyopia. Currently there are three pharmacological approaches to the treatment of presbyopia. The first one aims to produce miosis and, from a pinhole effect, increase depth of focus, and therefore improve uncorrected near visual acuity (UNVA). The second one addresses rehabilitating accommodation in a binocular way, allowing good vision at all distances. Finally, the third strategy uses lipoic acid to restore the lost elasticity of the lens. All of these pharmacological treatments are topical non-invasive eyedrops, with no serious adverse effects having been reported with any of the strategies, and require the right patient selection process to fulfill expectations and needs. The aim of this article is to provide an update on recent advances in this field.

Abstract
Purpose: Regression of the refractive outcome is a major concern of LASIK procedures mainly in presbyopic patients. The purpose of this study was to evaluate the long-term efficacy of the pharmacological treatment of presbyopia performed with Benozzi's method, in combination with hyperopic LASIK surgery in presbyopic population. Methods: A nonrandomized case series was developed, including presbyopic patients who underwent bilateral "Hyperopic LASIK surgery" and were pharmacologically treated with Benozzi's Method from January 2011 to August 2018, with at least 2 years of follow-up, at two private ophthalmological clinics of Argentina. Main outcomes were spherical equivalent (SE), uncorrected distance visual acuity (UDVA), and uncorrected near visual acuity (UNVA). Measurements were evaluated at baseline and postoperative at 1 month (without Benozzi's treatment), 2 months (starting with Benozzi's treatment), and 2 years. The SE stability across the time was statistically compared. Results: A total of 84 eyes of 42 patients, with a mean age at the time of the surgery of 51.07 ± 4.5 (42-59), were found following 2 years of follow-up. Patients have improved and maintained UDVA, achieving Jaeger 1 in the second postoperative month, which was maintained up to the last year of follow-up. Refractive stability across the time is observed comparing first month after surgery with the last year of follow-up, without statistical significant difference (p: 0.11). Conclusion: Hyperopic presbyopic patients that underwent LASIK surgery and 1 month after surgery started with the pharmacological treatment of presbyopia (Benozzi's method) results in excellent UNVA and UDVA that is stable over time without refractive regression.

Abstract
Purpose To evaluate the safety, visual performance, and patient satisfaction of a new presbyopic pseudophakic intraocular lens (IOL). Methods A prospective non-randomized case-series study was performed in Buenos Aires, Argentina. Patients included in the study underwent a programmed Femtosecond laser assisted cataract surgery (FLACS), performed between October and December 2020, with a 6-month follow-up period. The Intensity (Hanita Lenses) IOL was bilaterally implanted. Spherical equivalent (SE) refraction, uncorrected distance and near visual acuity (UDVA/UNVA), defocus curve, endothelial cell density (ECD), central corneal thickness (CCT), and a satisfaction questionnaire were evaluated. Results A total of 56 patients (112 eyes), aged 65 ± 6.12 years were included. The mean ± SD of preoperative SE was 1.85 ± 2.24 D (range; -4.50 to 4.75), which had decreased 6 months after surgery to -0.08 ±0.32 D (range; -0.75 to 0.63). No eyes experienced a loss of lines of vision, and 94% obtained SE values between ± 0.50 D. Defocus curve for different additions was 0.03 LogMAR (logarithm of the minimum angle of resolution) for -3.0 D, -0.005 LogMAR for -1.5 D, and -0.07 LogMAR for 0 D. The ECD, CCT remained stable (P: 0.09 and 0.58, respectively) and all patients achieved their preoperative expectations, with a 6-month follow-up period. Conclusion Patients who underwent a safe bilateral implantation with Intensity IOL achieved a high degree of spectacle independence and satisfaction, 6 months after surgery.

Abstract
PURPOSE OF REVIEW Despite affecting approximately 1.8 billion individuals worldwide, until recently, a pharmacologic treatment for presbyopia was not available. This special commentary reviews the treatment of presbyopia with a focus on the recently approved medication Vuity (pilocarpine 1.25%, Allergan, an AbbVie Company). RECENT FINDINGS Vuity is a re-engineered formulation of pilocarpine 1.25% specifically designed for the treatment of presbyopia. Recently published results from the GEMINI 1 Phase 3 clinical trial reported improvement in distance corrected near vision without significant compromise in distance vision. No unexpected safety findings were reported with mild headache being the most common adverse event. Notably, there were no reported cases of retinal detachment or angle closure during the 30-day phase 3 clinical trials. SUMMARY Vuity is the first treatment designed and FDA approved to treat the growing presbyopia market. Phase 3 clinical trials demonstrated its ability to improve near vision without significant compromise in distance vision. We recognize this paradigm shift in the treatment of presbyopia and anxiously await additional treatment options for this ubiquitous condition.

Abstract
Accommodation is the natural increase or decrease of the refraction of the eye lens as a function of the fixation distance. It relies on the proper elasticity of the natural eye lens. The evaluation of accommodation and the coupled convergent eye movements enables us to make the diagnosis of certain eye-related conditions and allows the differential diagnostic from some of the "neuroophthalmic diseases". This may avoid some unnecessary diagnostic procedures and reduce patient anxiety in terms of having a health threatening disease.

Abstract
Pharmacological treatment of presbyopia may be an alternative for those who want a spectacle-free scenario and an easy-to-use method with lower risk of irreversible ocular adverse events. There are two main agents, miotics and lens softeners, investigated as agents for the pharmacological treatment. Miotic agents treat presbyopia by creating a pinhole effect which may increase the depth of focus at all working distances. The miotic agents have been studied for application to only one eye for monovision or both eyes. Their effect is temporary with common adverse events, such as headache and dim vision at nighttime, with no known long-term safety and efficacy. There have been studies on the miotic agents in combination with other agents for additive treatment effects or lessening adverse events, however, these combination effects are not clear. Lens softeners increase the elasticity of the lens, which is targeted at one of the etiologic mechanisms of presbyopia. There is only one lens softener being investigated in only a few trials. The results were inconclusive. The recent approval of 1.25% pilocarpine for treatment of presbyopia by the US FDA may be an important milestone for investigation of real-world data of pharmacological treatment of presbyopia.
