Abstract Details

Purpose:

To study the effect of topical glycerine eye drop on improving  corneal oedema in cases undergoing DMEK surgery .

Setting:

Kasr El Eini Hospital Cairo University

Methods:

This is a comparative study of  40 eyes suffering from endothelial decompensation  with remarkable corneal oedema (600-900 um) and scheduled for DMEK. They were divided  into two groups of 20 eyes each  ;group (A ) received preoperative gylcerin syrup instilled as eye drops ( 5 times per day two days before the operation and every 5min for one hour immediately preoperative  ) while group( B ) did surgery without it   .Corneal thickness was measured preoperatively before and after eye drops .The duration of DM scoring  was recorded . All cases were operated  by the same surgeon .

Results:

This study included (  16 Male and 24 female) with age ranging from 40-80 years. Pseudophakic corneal decompensation was the main indication for surgery  (40 eyes).The corneal thickness was remarkably decreased in group A compared  than group B and it is statistically significant .The duration of DM scoring and unfolding of the injected DM was less in group A than in group B but it is statistically insignificant

Conclusions:

Use of gylcerin eye drop before DMEK surgery could be a useful tool to decrease corneal odema and improves visualising the diseased endothelium hence  accelerating  removal of the diseased endothelium unfolding of the graft  and reduces the operative time
