Cornea Ectasia Excimer Laser Treatment

Combined Technique of Corneal Remodeling to Treat Ectasia

To evaluate efficacy, safety, objective and subjective quality of vision after treatment of cornea ectasia with transepithelial topographic guided laser simultaneous Central Corneal Remodeling (CCR) and Cross-linking (CXL).

Background To evaluate efficacy, safety, objective and subjective quality of vision after treatment of cornea ectasia performed with transepithelial topographic guided laser simultaneous Central Corneal Remodeling (CCR) and Cross-linking (CXL).

Methods In this retrospective study 8 eyes of 8 patients (mean age 31.50±14.73 years) affected by cornea ectasia underwent simultaneous CCR and CXL. Preoperative and 6 month postoperative uncorrected distance visual acuity (UDVC) and distance corrected visual acuity (DCVA) were measured using the Efficacy and Safety index. Objective and subjective quality of vision were evaluated preoperatively and 6 months postoperatively using corneal morphological irregularity index (CMI), National Eye Institute Visual Function NEI-VFQ25 and NEI-VFQ39 questionnaires.

Inclusion Criteria:

- keratoconus with moderate severity (Amsler-Krumeich stage I-II)

Exclusion Criteria:

• concomitant ocular disease
• concomitant systemic disease
• corneal opacities
