[Bandage keratoplasty therapeutic-optical in treatment of progressing pellucid marginal corneal degeneration (a preliminary report)].

Purpose: To provide preliminary estimation of the effectiveness of bandage therapeutic-optical keratoplasty (BTOK; previously called inralamellar bandage keratoplasty) in patients with pellucid marginal corneal degeneration (PMD).

Material And Methods: The study included 7 patients (8 eyes) with PMD aged 35 to 55 years operated with intralamellar bandage keratoplasty, the follow-up period comprised 3, 6, and 12 months after the surgery.

Results: All patients with PMD operated with intralamellar bandage keratoplasty showed increase in visual acuity to an average of 0.55±0.35 a year after the surgery; by that time, the maximum refractive power of the cornea decreased to an average of -44.5±3.0 D. The area of stromal thinning was thickened by donor corneal flap. No signs of rejection were detected over the entire observation period.

Conclusion: Intralamellar bandage keratoplasty may be the method of choice to stop further progression of PMD with improvement of optical properties of the cornea.
