Abstract

PURPOSE:

To evaluate the efficacy of customized surface ablation in cases of forme fruste keratoconus.

DESIGN:

Prospective noncomparative case series.

PARTICIPANTS:

Eleven eyes of 8 contact lens-intolerant patients with forme fruste keratoconus treated at the Institute of Refractive and Ophthalmic Surgery and the University Eye Clinic Zurich.

INTERVENTION:

Topography-guided customized surface ablation by means of a scanning spot excimer laser.

MAIN OUTCOME MEASURES:

Visual acuity, refraction, quality of vision (ghosting), corneal topography including the Zernike parameter Z3.

RESULTS:

Statistically significant reduction of manifest refractive error, corneal irregularity, and ghosting. The spherical equivalent was reduced by -2.8+/-0.62 diopters (D) (P = 0.0007), the cylinder by 1.34 +/- 0.18 D (P = 0.015), Z3 was reduced by 41% (P<0.001), and all patients had less ghosting compared to their preoperative status. No eye lost > or =1 lines in best spectacle-corrected visual acuity; however, 7 of 11 eyes gained > or = 1 line.

CONCLUSION:

Topography-guided surface ablation is a promising option to rehabilitate vision in contact lens-intolerant patients with forme fruste keratoconus.
