Abstract

OBJECTIVE:

To describe a compressive lamellar surgical technique for treating severe astigmatism in peripheral corneal ectasia.

DESIGN:

Retrospective, noncomparative, interventional case series.

PARTICIPANTS:

Four eyes of 3 patients with either pellucid or Terrien's marginal corneal degeneration were included in this series.

METHODS:

C-shaped lamellar keratoplasty using multiple trephines of different sizes, with deliberate undersizing of the donor graft for a controlled compressive effect, was performed on these patients.

MAIN OUTCOME MEASURES:

Visual acuity outcome and refraction were measured at different intervals at up to 40 months of follow-up.

RESULTS:

All eyes achieved Snellen visual acuity of 20/40 or better and stable astigmatism ranging from 0 to -2.75 diopter cylinder within 6 months, with no recurrence of corneal thinning or peripheral corneal vascularization.

CONCLUSIONS:

Compressive C-shaped lamellar keratoplasty is able to reduce severe corneal astigmatism in peripheral corneal ectasia and can result in good visual and refractive outcomes with early visual rehabilitation.
