Hi Jing Long,
From my experience, cases of successful Medisave claims for ICL are usually quite few.
Unless your eyes have a difference of more than 300 degrees, or you have previously undergone other eye operations, ICL is generally considered a refractive surgery which you have to pay foron your own.
However, on a case by case basis, doctors may assist you in applying for these claims, but the outcome depends on the merits of the case scenarios.
