Abstract Details

Purpose:

There is evidence for intraoperative complication when treating myopic patients who are suffering from corneal epithelial dystrophy during LASIK surgery. Risk potentially includes intraoperative epithelium geting loose and postoperative epithelium ingrowth. We’ll discuss the safety and efficiency of SMILE operation for those patients.

Setting:

Ophthalmology Daping Hospital Third Military Medical University

Methods:

Background: Age of the 6 myopic patients included in the study ranged from 26 to 38 years old. There is no obvious refractive difference between OD and OS. Refractive diopter ranged from -6.25 D to -9.25 D. The corneal flaps making 4 eyes using Microkeratome , 2 eyes using VisuMax. It occurs that epithelial dystrophy on treating OD. (6 cases account for about 0.13% in total 4352 cases finished in Daping )Eye Center. The another eye (OS) have been treated with VisuMax 1 month later. Lenticule diameter ranged from 6mm to 6.5mm. Edge cutting is 3mm. Regularly finish the lenticule, separate and remove.

Results:

Both of LASIK and SMILE groups, corneal epithelial relaxation occurred in surgery, wearing soft corneal contact lens ,and removed after surgery?24 to 48 hours? , Postoperative 3 days only SMILE group 2 eyes reach best correcting outcome. Postoperative 1 week 3 eyes in LASIK group reached best correcting outcome, and epithelial ingrowth occurred in 5 eyes; All 6 eyes in SMILE Group reach best correcting outcome.,no epithelium ingrowth. Postoperative 1 to 2 months, 4 eyes in LASIK group need retreatment to cure epithelial ingrowth, and only 2 eyes could not reach best correcting outcome ( 1 row inferior)

Conclusions:

There is some risks to use LASIK to treat myopic patients suffering from corneal epithelial dystrophy. However we could obtain better safety and accuracy if we choose SMILE operation because it obviously avoids the postoperative complication like epithelium ingrowth.
