Purpose:
to propose treatment approach to the post-LASIK iatrogenic keratoectasia
Setting:
: The S.N. Fyodorov Eye Microsurgery Federal State Institution, Volgograd Branch
Methods:
there were performed three corneal crosslinking (CCL) procedures in 3 patients (males, mean age 32 years) in view of iatrogenic keratoectasia. Pre-surgical pachymetry equaled 350-370 µm, keratometric values at the top of keratectasia were from 48,0 to 53,0 D. Interface was delaminated by means of a spatula. A pouch was formed which was filled at first with a 0,1% hypotonic riboflavin solution and afterwards with a 0,1 % riboflavin solution on 20% dextran T500, the latter being additionally supplied every 5 min. In all the cases corneal thickness of 400 µm was achieved and maintained in course of all the CCL procedure.
Results:
within first twenty-four hours after CCL a moderate epitheliopathy regressing under epithelialization therapy was observed in all the patients. In course of the first 3 days there was noted a stromal edema of various degree. No cases of corneal flap disadaptation or epithelial ingrowth were registered. One month postoperatively and further on control keratotopographic examinations revealed that keratometric values at the top of keratectasia reduces by 1,0 D at the average in all the cases (from 0,5 to 1,5 D).
Conclusions:
the proposed technique of CCL in progressive keratectasia after LASIK is effective, easy to perform and well tolerated by the patients. Further dynamic follow-up is required.
