Effect of orthokeratology lenses on restoring visual acuity

Abstract

This study investigated the experience of users in wearing orthokeratology lenses, their subsequent visual acuity, and their opinions on said lenses. This study adopted a quantitative survey research method, with a questionnaire that was developed based on the said author’s past orthokeratology-wearing experiences and possible concerns that arise from wearing these lenses. The analysis results are consistent with those regarding the long-term effects of wearing orthokeratology lenses as described in the literature review section. For example, nearly 60% of the participants felt that visual acuity and the cornea would degenerate if they stopped wearing orthokeratology lenses within one year. Although studies have confirmed that wearing orthokeratology lenses has an immediate effect on ameliorating nearsightedness, the long-term effects on the health and morphological changes of the corneas must be evaluated further in the future.
