Abstract Details

Purpose:

To report the outcomes of Keraring implants combined with corneal cross linking in the management of keratoconus.

Setting:

Private Practice in Cape Town, South Africa

Methods:

This is a retrospective review of 27 eyes with IntraLase® FS 150 kHz (AMO) assisted Keraring implantation by the same surgeon, that was followed by  epi-off corneal cross linking after six weeks. .  Visual acuity, spherical equivalent and Oculus Pentacam® scans were obtained and compared at pre-intervention(s) and at least six month’s post-operatively.

Results:

89% of participants showed an improvement in UCVA and 82% had a better post operative BSCVA.   There was an average reduction on 1.19 D of myopic spherical equivalent, and 1.78 D reduction in total corneal cylinder. The Steepest K-value had an average of 2.9 flattening.   In this study, eyes that showed the best visual improvement, also had the most reduction in KMax and Total Deviation values.

Conclusions:

Corneal ring segments and cross linking provide a viable and less invasive option in treating Keratoconus.  Patient satisfaction was high. The need for keratoplasty can be delayed or eliminated by such interventions.
