PURPOSE: To analyze corneal curvature and visual acuity after asymmetric intrastromal corneal rings implantation, not following the nomogram proposed by the manufacturer.
METHODS: Seven eyes of seven keratoconus patients which had asymmetric corneal rings implanted in their corneal stroma were studied.
RESULTS: A flattening of the average corneal keratometry was noted in all patients, as well as an increase of the postoperative corneal asymmetry.
CONCLUSIONS: Asymmetric intrastromal corneal ring implant improves the postoperative visual acuity with and without correction. As a result we noticed flattening of the corneal curvature at the thicker ring implantation spot and increase of corneal asymmetry.
