Abstract Details


To compare complete ring implantation versus ICRS implantation to correct keratoconus.


Dar El Oyoun Hospital, Cairo University


30 eyes of keratoconic patients were included. 15 eyes had Femtosecond assisted Myoring corneal implantation (G1) and 15 had Femtosecond assisted Keraring segments (G2).Changes in UCVA ,BCVA, Mean K (Km) ,Sphere , topographic cylinder and Q value were recorded in all eyes between preoperative values and 6 weeks postoperatively.


In G1 the Km change was -6.15D , the UCVA change was -0.57 (LogMar) , BCVA change was -0.2 (LogMar) and the Q value change was 0.43. In G2 the Km change was -3.15D, the UCVA change was -0.48 (LogMar), BCVA change was -0.09 (LogMar) and the Q value change was 0.5. All means of both groups were not significantly different except for the Km change which was statistically significantly more in G1 (P=0.05).


Both Complete rings and ring segments implantation are effective for improving corneal and visual parameters in keratoconus. Complete ring implantation may have a more flattening effect on the anterior corneal surface FINANCIAL INTEREST: NONE
