Abstract Details

Purpose:

To compare the safety and efficacy results between combined cross-linking with keraring implantation and combined cross-linking with myoring implantation using femtosecond laser for treatment of keratoconus.

Setting:

Sohag University Hospital, University Hospital, Egypt.

Methods:

38 eyes of 24 patients with keratoconus where subjected to this study. Group (A) included 24 eyes of 14 patients and subjected to combined cross-linking with keraring implantation while Group (B) included 14 eyes of 10 patients and subjected to combined cross-linking myoring implantation. All eyes were subjected to preoperative and postoperative UCVA, BCVA, manifest refraction, slit lamp examination of anterior segment, IOP, fundus examination, keratometry and pachymetry assessed by Pentacam corneal topographies at 1week, 1 month, 3 and 6 months follow up period.

Results:

In Group (A), the preoperative mean UCVA was 2/60 while the postoperative mean UCVA was 6/60. The preoperative mean BCVA was 6/40 while the postoperative mean BCVA was 6/18. The preoperative K average was 53.40 D while the postoperative K average was 51.72 D. The postoperative astigmatic correction was 3.2 D. In Group (B), the preoperative mean UCVA was 3/60 while the postoperative mean UCVA was 6/48. The preoperative mean BCVA was 6/36 while the postoperative mean BCVA was 6/10. The preoperative K average was 54.65 D while the postoperative K average was 48.06 D. The postoperative astigmatic correction was 1.3 D.

Conclusions:

Combined cross-linking with keraring implantation is best for keratoconus cases with oval or oblique cones and best correcting the astigmatic component of keratoconus. Combined cross-linking with myoring implantation is best for keratoconus cases with central or nipple cones and best correcting myopic component of keratoconus.
