Abstract Details

Purpose:

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

Setting:

Roaya vision center Alexandria Egypt

Methods:

prospective non comparative case series.patients were treated with same setting ICR implanted by femtosecond laser( VisuMax ,Carl Zeiss Meditec) 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 682 eyes of 433 keratoconus patients with moderate keratoconus .

Results:

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

Conclusions:

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 FINANCIAL INTEREST: ... receives consulting fees, retainer, or contract payments from a company producing, developing or supplying the product or procedure presented
