The ability to see deeply affects how human beings perceive and interpret the world around them. For most people, eyesight is part of everyday communication, social activities, educational and professional pursuits, the care of others, and the maintenance of personal health, independence, and mobility. Functioning eyes and vision system can reduce an adult's risk of chronic health conditions, death, falls and injuries, social isolation, depression, and other psychological problems. In children, properly maintained eye and vision health contributes to a child's social development, academic achievement, and better health across the lifespan. The public generally recognizes its reliance on sight and fears its loss, but emphasis on eye and vision health, in general, has not been integrated into daily life to the same extent as other health promotion activities, such as teeth brushing; hand washing; physical and mental exercise; and various injury prevention behaviors. A larger population health approach is needed to engage a wide range of stakeholders in coordinated efforts that can sustain the scope of behavior change. The shaping of socioeconomic environments can eventually lead to new social norms that promote eye and vision health. Making Eye Health a Population Health Imperative: Vision for Tomorrow proposes a new population-centered framework to guide action and coordination among various, and sometimes competing, stakeholders in pursuit of improved eye and vision health and health equity in the United States. Building on the momentum of previous public health efforts, this report also introduces a model for action that highlights different levels of prevention activities across a range of stakeholders and provides specific examples of how population health strategies can be translated into cohesive areas for action at federal, state, and local levels.

Introduction: This PhO study investigates finite objective and subjective clinical outcomes of refractive surgery. Methods: A series of studies was conducted to investigate laser retreatment procedures, a comparison between the OPO-Scan and WaveScan aberrometers, a comparison of aberrometry changes following laser in situ keratomileusis (LASIK) and laser-assisted subepithelial keratectomy (LASEK), internal aberration changes following LASIK, the development of a quality of vision (OoV) questionnaire and the refractive outcomes of the SCHWINO Amaris excimer laser. Results: Good visual and refractive outcomes were found with LASEK retreatment and a high incidence (23%) of epithelial ingrowth occurred following flap-lift LASIK retreatments. In the comparison between the OPO-Scan and WaveScan, medium consistency was found for aberrations z;' and z~ with poor consistency for all other aberrations. In the comparison between LASIK and LASEK, both procedures caused increases to spherical aberration with LASIK additionally causing increases to two fourth-order aberrations and LASEK causing increases to two fifth-order aberrations. Investigations into internal aberrations found LASIK increased internal spherical aberration which attenuated the increase in anterior corneal spherical aberration. A OoV questionnaire was successfully developed utilising Rasch analysis demonstrating good precision, reliability, and internal consistency with good construct validity and test-retest reliability. The SCHWINO Amaris was found to be effective for the treatment of a range of refractive errors. Conclusion: Significant clinical finding were found for laser retreatments and primary treatments with two different laser systems. Aberrations were found to be poorly correlated with the OPO-Scan and the WaveScan. An effective OoV questionnaire was developed which may be used in prospective clinical and research studies."

The Report for the 2030 targets on effective coverage of eye care intends to serve as a reference point to commence monitoring progress towards the 2030 global targets that were endorsed by Member States at the 74th World Health Assembly. This report draws on key results from a comprehensive analysis of population-based eye health surveys and includes estimates of effective cataract surgery coverage (eCSC) and effective refractive error coverage (eREC) at the global level, by WHO region, sex and World Bank income level, and the relative quality gap (that is, the percentage difference between ‘effective coverage’ and ‘coverage’). It also serves to highlight key gaps in current data and presents suggestions for additional efforts required to advance the monitoring, policies and programmes for increasing the coverage of eye care interventions.

Abstract: We examined existing data from Food and Drug Administration (FDA) clinical trials for approved ophthalmic lasers to determine if trends for improvement in outcomes occurred with changes in laser technology. The repeatability of autorefraction measurements, visual acuity measurements, and the National Eye Institute Refractive Error Quality of Life (NEI-RQL-42) Questionnaire was evaluated in laser in situ keratomileusis (LASIK) patients. We also compared the performance of the NEI-RQL-42 to another survey for refractive surgery patients to see if similar results were obtained when subjects completed the surveys simultaneously. Finally, we evaluated patient survey responses and opinions of eye care practitioners to provide direction for generating hypotheses for future research studies. We found that cycloplegic autorefraction measurements with the Grand Seiko autorefractor were repeatable and agreed well with subjective refraction. The NEI-RQL-42 was determined to have an acceptable level of repeatability and produced results that were similar to other studies that tested refractive surgery patients. Measurements of low-contrast visual acuity under various lighting conditions were also found to have acceptable levels of repeatability, and 5% contrast visual acuity appears to be sensitive to differences between LASIK and non-LASIK patients. When evaluating reasons why patients would recommend LASIK to others, we determined that the primary reason was to eliminate the need for glasses and/or contact lenses. Focus group sessions with eye care practitioners revealed that practitioners would like to have more information about the relationship between patient personality and psychological issues and satisfaction with the results of the procedure. The eye care practitioners defined a successful LASIK procedure as one in which the patients had good uncorrected visual acuity, refractive error within " 0.50 D of the intended correction, and no new or increase in night vision or dry eye symptoms. Future studies in corneal refractive surgery patients should be able to use the measurement techniques evaluated in these studies to answer the following two research questions: What factors are associated with the dependence on glasses and/or contact lenses five years after LASIK, and what psychological factors are associated with the patient's view of a LASIK procedure?

A concise review and comprehensive guide to improving cataract surgery outcomes Significant advances have been made in refractive surgery in the last decade. Eye surgeons today can leverage many cutting-edge intraocular lens (IOL) technologies such as multifocal, extended depth of field, toric, accommodating, and aspheric. Concurrent innovations including optics, phacoemulsification, superior keratometry and biometry, and posterior cornea evaluation have resulted in improved cataract surgery outcomes. Recent advances in the diagnosis and treatment of cataracts have dramatically improved patient satisfaction following cataract surgery, yet common and rare complications still occur such as dry eye, endophthalmitis, and retinal detachment. Furthermore, only 80% of cataract surgery procedures bring patients to within 0.5 diopters of their needed refraction. Optimizing Suboptimal Results Following Cataract Surgery: Refractive and Non-Refractive Management presents the latest techniques for achieving optimal results and overcoming complications in cataract surgery. Internationally renowned ophthalmic surgery pioneers Priya Narang and William Trattler have created an unparalleled guide to overcoming complex cases and residual refractive errors. The book starts with six chapters on suboptimal causes and considerations, followed by dedicated sections covering refractive and non-refractive enhancements. The fourth section features chapters on keratoconus, cystoid macular edema, endophthalmitis, toxic anterior segment syndrome, and vitritis, as well as intraoperative aberrometry, futuristic approaches and advancements, and telescopic IOLs.
