Keratoconus is an ophthalmopathy that has high morbidity and is likely to cause blindness. The currently available therapeutic options for keratoconus mainly include wearing rigid gas permeable(RGP)contact lenses, corneal cross linking, and keratoplasty, etc., which, however, require high treatment cost and long-term medicinal treatment with indefinite therapeutic effect. Intracorneal lens implantation has emerged as a new technique for the treatment of keratoconus, which attempts to implant a lens of certain power into the corneal interlayer, so as to allow the visual acuity to recover quickly while treating keratoconus. This paper reviews the advances and the development prospect of intracorneal lens implantation.
