Treatment options were separated into four main categories: atropine, glasses, contact lenses, and orthokeratology. Search terms were queried across ten years of Google Trends data and the relative search volume was analyzed to quantify the change in search volume over time.Results: A positive linear trend over time was present for all myopia interest keywords except “nearsighted” (p = 0.074) and “near work myopia” (p = 0.086). Interest in the four myopia treatment categories included in this study also displayed a significant positive trend over time. There is also a statistically significant positive correlation between all four treatment options and four of the seven categories of population interest, “myopia control”, “myopia”, “myopia progression”, and “screen time myopia”.Conclusion: This study demonstrates the utility of GT to correlate public interest in myopia treatments over time. All treatment terms had statistically significant linear search volume growth over a ten-year period. The positive correlation between interest in myopia as a health problem and available treatments supports existing evidence that GT can track rising public health concerns and corresponding treatment-seeking behaviors.Keywords: myopia, Google Trends, nearsighted, orthokeratology, atropine

Secondarily, the demands on service provision over a 3-year period were described. Methods: Data on visual acuity, hospital visits, and injections were collected over 36 months on consecutive patients commencing treatment over a 9-month period. Visual outcome was determined for 1) all patients, using last observation carried forward for missed visits due to early discontinuation and 2) only those patients completing full 36-month follow-up. Results: Over 3 years, 120 patients cumulatively attended hospital for 1,823 noninjection visits and 1,365 injection visits. A visual acuity loss of

This study suggests an asymmetric multilevel inverter based on DSTATCOM that employs SVPWM techniques to produce higher output levels. There are two steps in the suggested inverter. One full bridge and two half bridges make up the inverter's main stage. A full bridge converter had four switches and a single DC source, while half bridges have separate DC sources with a voltage ratio of 1:3:3. Every cell has a fixed neutral point and is connected in a cascaded fashion. The inverter's performance is not improved by setting the DC source values equally. A folded cascaded H-bridge circuit running at a line frequency makes up the second circuit. Control plan PWM's space vector modulation was used to verify the suggested topology. Each control scheme's specific methodology as well as switching pulses are covered in great detail. In MATLAB/Simulink, the suggested system has been simulated with an output voltage of 350 V and an output current of roughly 3.5 A.
