Globally, the need for eye health services continues to grow and has been deemed a significant public health concern requiring immediate action.1 In 2019, an estimated 2.2 billion people worldwide had vision impairment, and at least 1 billion people had preventable or untreated causes of vision loss.2 The prevalence of visual disability is predicted to increase with the continued growth of populations and aging. The World Health Organization (WHO) has identified global eye health as a priority and previously launched VISION 2020: The Right to Sight initiative in 1999 to eliminate avoidable blindness globally by 2020.3 Although progress was made, not all of the goals for VISION 2020 were met.

The World Health Organization estimates that at least 2.2 billion people suffer from visual impairment globally.1 Nearly half of these cases are preventable or undertreated. Limitations in the accessibility and quality of vision care remain significant drivers of this burden of disease. These issues are important in every community regardless of socioeconomic status but disproportionately affect individuals in low-income and middle-income countries. “Accessibility” in this context refers to the ability of a person in need to contact, either virtually or in person, an appropriate care provider capable of diagnosing and managing the underlying etiology of their visual impairment. A number of barriers can limit accessibility, including the cost of receiving care, the physical distance between patient and provider and lack of feasible transportation to traverse this distance, communication limitations, including language and cultural barriers between provider and patient, lack of individual agency or a sense of not being a participant in one’s care, and an inadequate number of qualified providers relative to the burden of illness in the population. “Quality” of care refers to the amount of benefits

Corneal collagen crosslinking is a pharmacological treatment aimed at strengthening the corneal stroma using riboflavin combined with ultraviolet (UV) A irradiation.1 In 1998, Spoerl et al2 first described the strengthening effect of crosslinking with riboflavin and UV light on corneal tissue using porcine eyes. The photochemical reaction between riboflavin and UVA radiation produces additional chemical bonds that stiffens the stromal collagen fibers.3 In 2003, Wollensak et al3 showed in a pivotal study that corneal collagen crosslinking, using the “Dresden protocol,” halted the progression of keratoconus in all treated eyes, and even showed signs of regression in 16 of the 23 eyes. Subsequent studies have confirmed the efficacy of this protocol in halting the progression of keratoconus and its relative safety.4 However, it was not until 2017 that corneal collagen crosslinking was approved by the US Food and Drug Administration (FDA) for the treatment of progressive keratoconus and corneal ectasia after refractive surgery.5 Currently in the United States, there is only 1 standard crosslinking procedure that is approved by the FDA, which follows the Dresden protocol described in the study by Wollensak et al.5 The protocol involves removal of 8mm of central corneal epithelium, followed by instillation of riboflavin 0.1% with 20% dextran on the cornea for 30 minutes, and then UVA radiation at a wavelength of 370 nm and an irradiance of 3mW/cm for 30 minutes to deliver a total energy of 5.4 J/cm. Despite the general safety of this procedure, modifications to the standard protocol have been investigated
