According to these findings, posterior corneal steepening and thinning in keratoconus patients continue after the age of 40 years, but it is clinically negligible. According to his medical note, ever since the CXL, KC had been stable. Due to its early onset, it can impact school, work, social and family life if it's not treated. No participant had any systemic disease known to be associated with KC such as Down syndrome, Marfan syndrome, Ehlers-Danlos and other systemic connective diseases. (2021).

Epidemiology of keratoconus in the urals. 4. The disease can have a significant impact on quality of life18 and treatment modalities to halt its progression (such as corneal collagen cross-linking) or to improve vision (such as specially designed contact lenses, intra-corneal ring implantation or keratoplasty), although have shown good result, but are not free of risks and financial burdens.2,16,19 Patient education about the risk factors for this disease may aid in its prevention thereby reducing its overall impact. KC is known to be more common in areas with high sunlight exposure rate;20 however, other factors may be involved and on the contrary excessive ultraviolet sunlight exposure might promote natural cross linking of corneal collagen, assumed to be protective against the disease.20 The lack of significance of our results may be related to this dual protective and damaging effect of UV light, or the exposure dose could be at a subthreshold level for any demonstrable effect. His Kmax in the right eye (the worst eye) was 63.8 D (see Figure 1a), uncorrected vision was 20/100- and best-corrected acuity was 20/80. 14. 2016;35(5):673678. 1) and: (a) index of height decentration (IHD)=0.019; (b) index of vertical asymmetry (IVA)=0.33, which are common signs of post-CXL corneas (Fig. No sources of funding are declared for this study. It most commonly develops in teenagers and young adults and typically progresses for about 10 to 20 years before stabilizing. It happens because the cornea becomes progressively weaker and protrudes in a cone-like shape, as the name implies, instead of being regularly convex on its front surface. [ 24, 25] This new treatment is aimed at the pathogenic cause of . PN and ST were major contributors in collection of data and reviewed the manuscript. Number 3099067.
