To analyse safety, predictability and LASIK complication following 8624 individualized corneal flaps created by One Use-Plus SBK automated microkeratome (Moria SA, France)
Ophthalmology Daping Hospital Third Military Medical University
4621 ametropic patients, aging from 18 to 54, have been treated in 4 different eye centers from 2009 to 2012, with 1-month postoperative follow-up completed for 4550 patients. Preoperative ametropia ranged from -13.25 D to +6.25 D, 96% being myopes, and 34 eyes being treated for post radial keratotomy. Intended flap thickness was 100 microns using OUP SBK microkeratome. Choice of metallic suction rings was based on preoperative keratometry. Then Allegretto excimer laser was used for the consecutive photoablation.
Surgery time was 3 minutes per eye, and flap thickness was 98.0 +/- 8.1 microns (ultrasound) Intraoperative complication included: incomplete flaps (0.02%), and free flap (0.03%). There was no buttonhole, and no procedure was avorted. Edge bleeding occurred in 5.6% of eyes, and edge irregularities in 16.6% of eyes. Postoperatively, there were 4.8% and 0.01% cases of DLK grade I and II respectively, and 3.1% epithelial ingrowth.
The safety and predictability of OUP SBK modern and precise microkeratome carrying out LASIK surgery is as good as femtosecond laser, along with the enhancement of microkeratome design and technology. On the other hand, modern precise microkeratome is more economical and convenient than femtosecond laser.
