BACKGROUND: Presbyopia is a progressive condition that reduces the eye's ability to focus on near objects with increasing age. After a systematic literature review identified no existing presbyopia-specific patient-reported outcome (PRO) instruments meeting regulatory guidance, a new PRO instrument, the Near Vision Presbyopia Task-based Questionnaire (NVPTQ), was developed. RESULTS: To explore the patient experience with presbyopia, concept elicitation interviews were conducted with 20 presbyopic participants...

INTRODUCTION: Presbyopia is a progressive, age-related visual condition that is characterized by reduced ability to focus on near/close objects, causing impacts on individuals' daily function and health-related quality of life. The Presbyopia Impact and Coping Questionnaire (PICQ) is a new patient-reported outcome (PRO) instrument that assesses presbyopia impact and use of coping behaviors among presbyopic individuals. METHODS: To document the impacts of presbyopia and associated coping behaviors, concept elicitation (CE) interviews were conducted with 20 presbyopic participants...

Background: Presbyopia is a primary cause of a decline in near vision. In this study, we developed a new mixed herbal medicine to retard presbyopic progression and increase the amplitude of accommodation (AA), which is beneficial for near vision. Methods: A total of 400 participants between the ages of 45 and 70 years were recruited. We designed the mixed herbal drug to include Cassiae Semen (200 mg), wolfberry (200 mg), and Dendrobium huoshanense (DD) (40 mg) in one capsule...

Presbyopia is a common age-related vision disorder characterized by a progressive inability to focus on near objects. If uncorrected or under-corrected, presbyopia can significantly impact patients' quality of life. Presbyopia represents an area of considerable unmet need due to its rising prevalence worldwide as the population ages, the high proportion of under-treated individuals in some parts of the world, and the limitations of currently available corrective methods. Progressive or bifocal spectacles are associated with peripheral blur, a restricted visual field and impaired depth perception, which have been linked to an increased risk of falls in the elderly...

BACKGROUND: Presbyopia treatment in pseudophakic patients with a monofocal IOL is challenging. This study investigates the refractive results of femto-PresbyLASIK and analyzes presbyopia treatment in pseudophakic eyes. METHODS: 14 patients with 28 pseudophakic eyes were treated with femto-PresbyLASIK. The dominant eye was targeted at a distance and the non-dominant eye at -0.5 D. The presbyopic algorithm creates a steepness in the cornea center by using an excimer laser that leads to corneal multifocality...

Corneal inlays (CIs) are the most recent surgical procedure for the treatment of presbyopia in patients who want complete independence from the use of glasses or contact lenses. Although refractive surgery in presbyopic patients is mostly performed in combination with cataract surgery, when the implantation of an intraocular lens is not necessary, the option of CIs has the advantage of being minimally invasive. Current designs of CIs are, either: small aperture devices, or refractive devices, however, both methods do not have good performance simultaneously at intermediate and near distances in eyes that are unable to accommodate...

Since the introduction of femtosecond laser (FS) systems for corneal flap creation in laser-assisted in-situ keratomileusis there have been numerous applications for FS laser in corneal surgery. This manuscript details the utility of FS lasers in corneal surgical procedures including refractive laser surgeries, intracorneal ring segment tunnels, presbyopic treatments, and FS-assisted keratoplasty. We also review the role of FS lasers in diagnostic procedures such as two photon excitation fluorescence and second harmonic generation...

PURPOSE: To evaluate the visual outcomes of patients with presbyopic hyperopia, comparing the current standard of monovision treatment with a novel bilateral presbyopic LASIK (Custom-Q mode) technique. METHODS: This prospective comparative study of consecutive eligible patients with presbyopic hyperopia undergoing a bilateral presbyopic laser in situ keratomileusis technique was conducted between January 2018 and February 2019. After contact lens-simulated monovision measurements were obtained, the non-dominant eyes had a negative aspheric ablation profile planned using the Custom-Q nomogram (Alcon Laboratories, Inc)...

Presbyopia is one of the most well-known diseases of the eye, predominantly affecting the adult population after 50 years'. Due to hardening of the lens and failure of accommodative change, patients lose the ability to focus on near objects. This eye symptom is reported to be an early symptom of age-related nuclear cataract, and we have previously reported that hesperetin treatment could delay the onset of nuclear cataractogenesis induced by sodium selenite. In this study, we examined whether oral intake of α-glucosyl-hesperidin (G-Hsd), which has greater water solubility than hesperetin, could delay the onset of presbyopia...

PURPOSE: Accommodative insufficiency (AI), defined as the inability to stimulate accommodation in pre-presbyopic individuals, has gained much attention over recent years. Despite the enormity of the available information, there is a significant lack of clarity regarding the criteria for definition, methodology adopted for testing and diagnosis, and the varied prevalence across the globe. This review aims to gather evidence that is pertinent to the prevalence, impact and efficacy of available treatment options for AI...

PURPOSE: To perform a pilot evaluation of a novel pharmacological therapy for presbyopia in patients with previous corneal refractive surgery. METHODS: This interventional study included 130 presbyopic patients. The patients were divided into three groups: (1) LASIK group, which included patients with previous LASIK for myopia or hyperopia; (2) previous presbyopia surgery group, including patients with previous monovision or PresbyLASIK (PresbyMAX, SCHWIND eye-tech-solutions GmbH, Kleinostheim, Germany); and (3) control group, which included presbyopes without any corneal refractive procedure...

PURPOSE: To evaluate the efficacy of simultaneous laser in situ keratomileusis (LASIK) and small-aperture corneal inlay (KAMRA; AcuFocus, Inc) implantation in hyperopic presbyopic eyes at 5 years postoperatively. METHODS: This was a retrospective single-center study of patients with hyperopia and presbyopia who underwent simultaneous LASIK and corneal inlay implantation by two experienced refractive surgeons. These patients were regularly observed for 5 years and evaluated with serial corneal tomographies and refractive assessments for uncorrected near visual acuity (UNVA), uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), distance-corrected near visual acuity (DCNVA), and manifest refraction spherical equivalent (MRSE)...

Refractive surgery refers to any procedure that corrects or minimizes refractive errors. Today, refractive surgery has evolved beyond the traditional laser refractive surgery, embodied by the popular laser in situ keratomileusis or 'LASIK'. New keratorefractive techniques such as small incision lenticule extraction (SMILE) avoids corneal flap creation and uses a single laser device, while advances in surface ablation techniques have seen a resurgence in its popularity. Presbyopic treatment options have also expanded to include new ablation profiles, intracorneal implants, and phakic intraocular implants...

A new class of diffraction-based corneal inlays for treatment of presbyopia is described. The inlay is intended to achieve an improvement of the near focus quality over previous designs. Our proposal is a two-zone hybrid device with separated amplitude and phase areas having a central aperture and no refractive power. An array of micro-holes is distributed on the surface of the inlay conforming a binary photon sieve. In this way, the central hole of the disk contributes to the zero order of diffraction, and the light diffracted by the micro-holes in the peripheral photon sieve produces a real focus for near vision...

We report a case of transient corneal ectasia developed after phacoemulsification in an eye previously treated with INTRACOR. There was a myopic refractive surprise after cataract surgery. Corneal tomography showed an increase in keratometry and elevation profile compared with preoperative examination. Soft contact lenses and intraocular pressure-lowering medications were prescribed as interim treatment. Clinical improvement was seen gradually, and the resolution of myopia and ectasia was achieved at 3 months...
