Hello You have reasonable good corneal thickness for C3R. This is less likely or unlikely to reduce drastically to critical value in 3 months

Hi. Can you share your complete investigation profile,

But your corneal thickness u are saying is 480...it will not come down drastically in 3 months C3R is done in progressive keratoconous , not necessarily for all cases ! Your eye doc will be the best person to guide you ..in case of doubts..u can take a second opinion to feel better n confirm. It is relatively simple procedure ..depends on where u r based.
