    The goal of this retrospective case series is to demonstrate the effectivity of combination low-dose atropine therapy with peripheral defocus, double concentric circle design with a center distance soft contact lenses at controlling myopia progression over 1 year of treatment. Included in this series are 3 female children aged 8–10 years with progressing myopia averaging −4.37 ± 0.88 D at the beginning of treatment. Their average annual myopic progression during the 3 years prior to therapy was 1.12 ± 0.75 D. They had not attempted any myopia control treatments prior to this therapy. The children were treated with a combination of 0.01% atropine therapy with spherical peripheral defocus daily replacement soft lenses MiSight® 1 day (Cooper Vision, Phoenix, AZ, USA). They underwent cycloplegic refraction, and a slit-lamp evaluation every 6 months which confirmed no adverse reactions or staining was present. Each of the 3 children exhibited an average of 0.25 ± 0.25 D of myopia progression at the end of 1 year of treatment. To the best of the authors’ knowledge, this is the first published study exhibiting that combining low-dose atropine and peripheral defocus soft contact lenses is effective at controlling children’s moderate to severe myopia progression during 1 year of therapy

    Photorefractive keratectomy (PRK) has long been the method of choice for refractive surgery in pilots, and was FDA approved for U.S. Air Force aviators in 2000. We retrospectively reviewed the medical records of 16 male combat pilots (mean age 25.0 ± 5.5 years) who had undergone bilateral laser refractive surgery with surface ablation (alcohol-assisted PRK: 81.25%, transepithelial-PRK: 18.75%), and who had a mean baseline spherical equivalent (SE) of −2.1 ± 0.7 D in the right eye, and −2.0 ± 0.7 D in the left. The mean follow-up was 8.4 ± 6.6 months. On the last visit, the uncorrected visual acuity (UCVA) had improved from 0.75 ± 0.33 logMar to −0.02 ± 0.03 logMar (p < 0.001), and from 0.72 ± 0.36 logMar to −0.02 ± 0.05 logMar (p < 0.001), for the right and left eyes, respectively. The percentages of participants with a right eye UCVA of at least 0.0, −0.08, and −0.18 logMAR (6/6, 6/5, and 6/4 Snellen in meters) were 100%, 37.5%, and 6.2%, respectively, and for the left eye, 93.7%, 43.75%, and 6.2%, respectively. No complications occurred. This is the first study to assess refractive surgery outcomes in a cohort of Israeli combat pilots. Surface refractive surgery effectively improved UCVA and reduced spectacle reliance for the members of this visually demanding profession

    Visual rehabilitation after a keratoplasty is often compromised due to high amounts of residual astigmatism. Femtosecond laser-assisted astigmatic keratotomy (FLAK) is gaining popularity in decreasing this astigmatism. Though one set of two incisions suffices in most cases, sometimes the treatment proves insufficient and additional treatment is required. This case series evaluates the outcomes in patients who underwent two consecutive FLAK sets to correct post-keratoplasty residual astigmatism. All repeated FLAK cases performed on post-keratoplasty eyes were reviewed in a high-volume clinic as a non-comparative retrospective case series. The data extracted include the procedure parameters, time between procedures, refraction including sphere, astigmatism, spherical equivalent (SE), and uncorrected and best-spectacle-corrected distance visual acuity (UDVA, BSDVA, respectively). Eleven eyes of eleven patients aged 25.5 &plusmn; 10 treated with more than one FLAK procedure were identified. The average follow-up time was 6 months after the first FLAK and 24 &plusmn; 10 months after the second. The second FLAK was performed six months after the first. The preoperative mean astigmatism was &minus;9.59 &plusmn; 2.36 D. At the final follow-up, the mean astigmatism decreased to &minus;5.38 &plusmn; 1.79 D (p = 0.001). Repeated FLAK procedures achieved a significant and stable reduction of astigmatism in post-keratoplasty eyes. This procedure shows safety and effectivity in these complex eyes and may prevent the need for a further keratoplasty

    Nitric oxide (NO) is acknowledged as a vital intercellular messenger in multiple systems in the body. Medicine has focused on its functions and therapeutic applications for decades, especially in cardiovascular and nervous systems, and its role in immunological responses. This review was composed to demonstrate the prevalence of NO in components of the ocular system, including corneal cells and multiple cells in the retina. It discussed NO’s assistance during the immune, inflammation and wound-healing processes. NO is identified as a vascular endothelial relaxant that can alter the choroidal blood flow and prompt or suppress vascular changes in age-related macular degeneration and diabetes, as well as the blood supply to the optic nerve, possibly influencing the progression of glaucoma. It will provide a deeper understanding of the role of NO in ocular homeostasis, the delicate balance between overproduction or underproduction and the effect on the processes from aqueous outflow and subsequent intraocular pressure to axial elongation and the development of myopia. This review also recognized the research and investigation of therapies being developed to target the NO complex and treat various ocular diseases

    Introduction: Though patients with nanophthalmos frequently endure decreased quality of vision with contact lenses or spectacles, refractive surgery is generally an inadequate alternative due to the associated high refractive error. A refractive lens exchange (RLE) is an alternative option but is technically challenging, requiring accuracy in biometry measurements and procedures. Case Presentation: This case discusses a 27-year-old female with nanophthalmos (axial lengths 17.6 mm and 17.4 mm, right and left eyes, respectively) who underwent a femtosecond laser-assisted (FLA) RLE with simultaneous implantation of a monofocal and a Sulcoflex trifocal (Rayner, Britain) lens in each eye. Preoperative cycloplegic refraction was +11.50/−0.75 × 145 and +12.00/−1.00 × 35 in the RE and LE, respectively. Best-corrected visual acuity (BCVA) at distance and near in the RE and LE was 6/7.5 and J1, 6/8.5 and J2, respectively. Uncorrected visual acuity (UCVA) was &gt;6/120 and &gt;J14 for each eye. FLA RLE was performed in the RE, then in the LE 2 weeks later. In each eye, a monofocal (44.0 D, RE, and LE) and a Sulcoflex trifocal lens (both implants, Rayner, Britain) were implanted in one procedure. Distance and near UCVA measured 6 weeks post-op RE and 1-month post-op LE at 6/8.5 and J1 in the RE, 6/10 and J1 in the LE. The RE and LE refraction and BCVA were +0.50/−1.00 × 115, 6/7.5, and plano/−1.00 × 55, 6/8.5, respectively. The post-op outcomes were uneventful. Conclusion: A single procedure concurrently implanting a monofocal and Sulcoflex trifocal intraocular lens in nanophthalmic eyes resulted in an excellent UCVA. This procedure can be considered esthetic and reconstructive as it significantly improves patient appearance and function

    Vision through Healthy Aging Eyes

    As life expectancy grows, so too will the number of people adversely affected by age. Although it is acknowledged that many conditions and diseases are associated with age, this mini-review will present a current update of the various visual changes that generally occur in healthy individuals disregarding the possible effects of illness. These alterations influence how the world is perceived and in turn can affect efficiency or the ability to perform ordinary daily tasks such as driving or reading. The most common physical developments include a decreased pupil size and retinal luminance as well as changes both in intercellular and intracellular connections within the retina along the pathway to the visual cortex and within the visual cortex. The quantity and the physical location of retinal cells including photoreceptors, ganglion and bipolar retinal cells are modified. The clarity of intraocular organs, such as the intraocular lens, decreases. These all result in common visual manifestations that include reduced visual acuity, dry eyes, motility changes, a contraction of the visual field, presbyopia, reduced contrast sensitivity, slow dark adaptation, recovery from glare, variation in color vision and a decreased visual processing speed. Highlighting these prevalent issues as well as current and possible future innovations will assist providers to formulate treatments and thereby conserve maximum independence and mobility in the modern mature population

    PURPOSE: To assess the additive potency of low-dose atropine combined with optical measures designed to decrease myopia progression. MATERIALS AND METHODS: This retrospective study included 104 myopic children aged 5–12 over 4 years, divided into five groups: daily instillation of 0.01% atropine and distance single-vision spectacles (A), 0.01% atropine and progressive addition lenses (A + PAL), 0.01% atropine and soft contact lens with peripheral blur (A + CL). Two control groups were included, prescribed bifocal spectacles or single vision (SV) spectacles. Cycloplegic spherical equivalence refraction was measured biannually, including 1 year after cessation of treatment. RESULTS: A significant decrease in myopia progression was noted during the 2nd and 3rd years of atropine treatment: A −0.55 ± 0.55D, −0.15 ± 0.15, −0.12 ± 0.12D were 1st, 2nd, 3rd years, respectively, A + PAL −0.47 ± 0.37D, −0.10 ± 0.25D, and −0.11 ± 0.25D were 1st, 2nd, 3rd years, respectively, A + CL −0.36 ± 0.43D, −0.13 ± 0.29D, and −0.10 ± 0.27D were 1st, 2nd, 3rd years, respectively. Myopia progression over 3 years, respectively, was −0.82 ± 0.50D, −0.70 ± 0.69D, −0.59 ± 0.66D in the bifocal group and −1.20 ± 1.28D, −0.72 ± 0.62D, −0.65 ± 0.47D in the SV group. One year after cessation of atropine treatment, myopia progression was − 0.32 ± 0.31D in A, −0.23 ± 0.28D in A + PAL, and −0.18 ± 0.35D in A + CL. CONCLUSION: Atropine 0.01% presented as effective at decelerating myopia progression, more prominent in the 2nd and 3rd years of treatment. Combining atropine 0.01% with optical modalities exhibited a trend for added efficacy over monotherapy. A + CL exhibited the least rebound effect 1 year after cessation of treatment
