Inclusion criteria

Inclusion criteria: All patients who underwent intrastromal corneal ring implantation between November 2009 and December 2012 in Sorocaba Ophthalmological Hospital. Surgical technique exclusively manual or using fentosecond LASER assistance. Patients whose implants used were Kerarings of 5mm diameter.

Design outcomes

Primary

MeasureTime frame
Expected outcome: the implantation of intrastromal corneal ring is effective in improving visual acuity in patients with different corneal ectasia or irregular astigmatism.;Expected outcome: the implantation of intrastromal corneal ring reduces the refrative error in patients with different corneal ectasia or irregular astigmatism.—

Secondary

MeasureTime frame
Expected outcome: the implantation of intrastromal corneal ring decreases keratometric indices in patients with different corneal ectasia or irregular astigmatism.;Expected outcome: the implantation of intrastromal corneal ring is safe (complications related to the procedure) for patients with different corneal ectasia or irregular astigmatism.—
