Background: Non-inflammatory corneal stromal thinness causes the central or paracentral region of the cornea to thin and protrude anteriorly, leading to myopia, irregular astigmatism, and vision impairment with keratoconus (KC). About 90% of the time, it is bilateral, but the severity and progression are asymmetrical. It normally begins around the time of puberty and continues until the third or fourth decade of life before stopping. The severity of the condition, the degree of visual impairment, and the benefits and drawbacks of each treatment option all play a role in determining the best course of medical or surgical treatment.
Objective: review article aimed to assess the new modalities of keratoconus management.
Methods: PubMed, Google scholar and Science direct were searched using the following keywords: Keratoconus, keratoconus management, corneal cross linking and intrastromal corneal ring segments. The authors also screened references from the relevant literature, including all the identified studies and reviews, only the most recent or complete study was included between March 2009 and January 2022. Documents in a language apart from English have been excluded as sources for interpretation. Papers apart from main scientific studies (documents unavailable as total written text, conversation, conference abstract papers and dissertations) were excluded.
Conclusion: It is possible to conduct corneal cross linking and intrastromal corneal ring segments methods simultaneously or in a sequential order, which has a beneficial effect on KC treatment. Several other methods with promising outcomes have been described in the literature.
