Purpose: To asses clinical features after intra stromal corneal rings segments (ISCRS) in corneal ectasias.

Methods: An historic cohort was studied. Descriptive variables were: age, gender and visual acuity; analized variables were: stromal depth planed to implant corneal rings vs mesured by OCT visante (chi square) and complications in and after surgery (CI to binomial proportions) and follow up.

Results: Twentythree eyes (18 patients) were analized, of them 10 were male, median age was 28 years (range 18-40), visual acuity of 3 logMAR or worst. All ISCRS were INTACS(TM), 0.45mm segment thickness. Complications (6 cases) were: neovascularization (2) and superfitial placement (4) CI=0.12-0.51.Two patients underwent renoval of ISCRS due to superfitial placement. Stromal depth compared p<0.001

Conclusions: In conventional thecnique the depth predicted is hard to achieved and complications more than expected.

Keywords: 462 clinical (human) or epidemiologic studies: outcomes/complications • 552 imaging methods (CT, FA, ICG, MRI, OCT, RTA, SLO, ultrasound)
