Abstract Details

Purpose:

To assess the outcome of collagen cross-linking (CXL) in keratoconus eyes after implantation of Kera intracorneal ring segments.

Setting:

Nokhba Center for Eye Surgery and LASIK, Mansoura, Egypt.

Methods:

twenty one eyes of 13 patients suffering  from mild to moderate degree of Keratoconus were included in this study.  All eyes had uneventful surgery for Kera intracorneal ring segment implantation followed by collagen cross-linking (CXL) treatment after at least 3 months of the implantation. Inclusion criteria were absence of corneal scarring and corneal thickness higher than 400 mm. Uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), spherical equivalent and cylinder refraction, and the mean keratometric (K) values were evaluated pre and postoperatively.

Results:

The mean age was 21.36±4.46 years. UCVA and BCVA were 0.05±0.02 and 0.18±0.1 respectively; after kera ring, the mean UCVA and BCVA were 0.23±0.17 and 0.39 ±0.18 (p=0.000) respectively. CXL after Kera ring resulted in an additional change in UCVA and BCVA to become 0.23±0.17 (p=0.951) and 0.41±0.18 (p=0.08) respectively. The decrease in spherical equivalent, cylindrical and mean keratometric value was 2.8D (p<0.05), 2.1 D (P<0.05) and 2.5 D (P<0.05) respectively after Kera ring treatment. Decrease of 0.11D (P>0.05), 0.01D (P>0.05) and 0.09 D (P>0.05) was obtained after CXL in each respective parameter

Conclusions:

Collagen cross-linking has an additive effect after kera ring  implantation and may be considered as an enhancement/stabilizing procedure
