Abstract Details


To evaluate safety , efficacy and corneal biomechanics change of combined intracorneal rings(ICR) implanted using femtosecond laser and cross linking in keratoconus patients.


Roaya Vision center & IFLC (international femto laser center


Prospective non comparative case series.patients were treated with same setting ICR implanted by femtosecond laser and 5 minutes epi-off cross linking.UCVA,BSCVA,K reading, CH and CRF were measured in all cases before surgery and after 3,6 months and 1 year of follow up of 1182 eyes of 713 keratoconus patients with moderate keratoconus .


Mean preoperative Uuncorrected visual acuity (UCVA) , best spectacle corrected visual acuity(BSCVA), corneal curvature( k readings) were 0 .2 ,0.5 and 53 respectively.mean corneal hysteresis(CH) and corneal resistence factor(CRF) were 6.7 and 7.1 respectively.


ICR implanted using femtosecond laser and cross linking in keratoconus patients is a safe and effective procedure with long term stability and has a good impact on corneal bomechanics.
