Method for preventing postoperative ametropia by performing modified penetrating keratoplasty

Rationale: Penetrating keratoplasty (PKP) often remains the only possible radical treatment for patients with corneal pathologies, one of which is keratoconus in the late stages [1]. The main criterion for the success of keratoplasty today remains transparent engraftment of the graft, but nowadays it is becoming increasingly important to achieve high clinical and functional results after surgery, which directly depends on the degree of ametropia of the operated eye [2]. Today, a fairly large number of methods for preventing postkeratoplastic ametropia are known, but as studies have shown, each method has a number of disadvantages. Therefore, at present, the search for an optimal method for intraoperative correction of ametropia in patients with keratoconus, allowing to obtain a stable result, is still relevant.
