To asses clinical features after intra stromal corneal rings segments (ISCRS) in corneal ectasias.
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.
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
In conventional thecnique the depth predicted is hard to achieved and complications more than expected.
