Глубокая передняя послойная и сквозная кератопластика `при развитой и далекозашедшей стадии кератоконуса

Abstract

This article presents the results of surgical treatment of 30 patients (30 eyes) with keratoconus stage 3-4, which were divided into two groups depending on the performed surgery technique. Deep anterior lamellar keratoplasty (DALK) was performed on 20 eyes using a femtosecond laser and the surgery technique including separation of the residual corneal stroma using the "big bubble" technique, and in some cases using the manual dissection technique. In 25% of cases (5 out of 20 eyes), the DALK operation was complicated by Descemet's membrane perforation and therefore, the surgical intervention was completed by switching to penetrating keratoplasty (PK). These patients were excluded from the DALK group and included in the PK group, who underwent penetrating keratoplasty (15 eyes). The maximum follow-up period was 2 years. After DALK transparent engraftment was achieved in all cases, and after PK in 93.4% of cases, in one case (6.6%) graft rejection was observed. Key words: keratoconus, surgical treatment, deep anterior lamellar keratoplasty, penetrating keratoplasty.
