Combined corneal biomechanical and tomographical indices in subclinical and forme fruste keratoconus.

ABSTRACT:

Purpose

Evaluation of combined corneal tomographic and biomechanical parameters in subclinical/forme fruste keratoconus (ScKC/FFKC).

Design

Cross-sectional observational case-control study.

Methods inclusion criteria

Thirty-one eyes with ScKC (fellow eye of KC with any one sign: keratometry >47 diopters, cylinder >1.5 D, central corneal thickness <500 µm, with/without abnormal topography) or FFKC (fellow eye of KC with normal topography and slit lamp examination) >13 years (cases) and 44 eyes of age-matched 22 healthy subjects (controls).

Exclusion criteria

Clinically diagnosed KC, presence of corneal scars, and prior ocular surgery eyes.

Study parameters

Sixteen Pentacam, 15 Corvis ST, and five Sirius parameters were analyzed using paired sample t -test
