PURPOSE: To evaluate the clinical and functional outcomes of bandage therapeutic-optical keratoplasty (BTOK) surgery in patients with keratoconus (KC) and significant changes in corneal thickness.
MATERIAL AND METHODS: Surgical treatment was performed in 15 patients (15 eyes) with stage IV KC aged from 22 to 51 years (mean age - 32.61±7.94 years). The follow-up period lasted 3 years. All patients underwent BTOK surgery using an interlamellar graft with a thickness of 320 to 350 µm.
RESULTS: Uncorrected and best corrected visual acuity increased in all patients after BTOK surgery and did not change statistically significantly during the entire follow-up period (3 years), amounting to 0.47±0.12 and 0.53±0.13, respectively. Keratometric parameters also remained stable by that observation time point and amounted to: Kmax - 53.01±2.30 D; Kmin - 41.63±2.24 D; Km - 47.32±1.91 D.
CONCLUSION: The BTOK surgery helps achieve long-term (3 years) visual, optical and strengthening outcomes in stage IV KC patients when the use of other known techniques (corneal collagen crosslinking, corneal segments) is technically impossible because of the risk of complications due to significantly thinned cornea (less than 400 µm).
