Abstract Details

Purpose:

To evaluate epi �â�€�“ off corneal collagen crosslinking (CXL) using refractive stromal lenticule of another patient undergoing small incision femtosecond lenticule extraction in patients having keratectasia with thinnest pachymetry value of less than 400 microns and not treatable using standard de-epithelialization techniques

Setting:

Centre For Sight Eye Hospital, New Delhi

Methods:

Five patients with progressive keratectasias with thinnest pachymetry from 360 �Î�¼m to 397 �Î�¼m underwent CXL using refractive stromal lenticule from patients undergoing small incision femtosecond lenticule extraction for moderate myopia (-2 to -4) on Visumax and thickness ranging from 110 to 120 �Â�µm. Epithelium was debrided and stromal lenticule, harvested simultaneously, was placed so that the centre corresponded to the apex of the cone. Thereafter CXL was carried out in the standard manner The patients underwent complete ophthalmological examination, including endothelial cell density measurements and computerized videokeratography, before CXL and at one, 6, and 12 months thereafter.

Results:

Epithelial healing was complete in all patients within 5 days of use of a soft bandage contact lens. No side effects or damage to the limbal region was observed during the follow-up period. All patients showed stability of K readings after 6 months. Demarcation line was observed in all the cases

Conclusions:

The new technique of using refractive stromal lenticule for CXL increases the corneal thickness in most physiological way. In our series, it was found to be a safe, effective and viable alternative to enhance corneal thickness during CXL in patients with keractectasia having thin or ultrathin corneas.
