How might corneal dystrophy, Avellino type be treated?

There is no cure for this condition and treatment usually focuses on alleviating symptoms, especially when vision becomes significantly impaired. Penetrating keratoplasty, which is a surgical procedure where a damaged or diseased cornea is entirely replaced by donated corneal tissue (graft), can improve vision at least temporarily but deposits tend to recur. LASIK eye surgery has been reported to exacerbate the number and density of the eye opacities. Patients treated with phototherapeutic keratectomy (PRK), which is a surgical procedure that uses a laser to remove tissue from the cornea, may do better and can retain corneal clarity for a decade or more.[1][2][3]
