Abstract Details

Purpose:

To report the risk factors and visual result of an opaque bubble layer (OBL) during creation of LASIK flap with the femtosecond laser.

Setting:

MAGRABI HOSPITAL KSA ASSER

Methods:

RETROSPECTIVE STUDY Visual acuity, manifest refraction, intraocular pressure, corneal curvature, corneal thickness, and hard docking procedure were evaluated. Patients divided in two groups, OBL-group and OBL-free group. Clinical outcomes in the 2 groups were compared to measure the risk factors and clinical effects of an OBL.

Results:

The study included 106 myopic eyes. The incidence of OBL was in 9 patients. The mean flat keratometry was steeper and the preoperative cornea thicker in the OBL-occurrence group. The OBL-occurrence group had harder applanation than the OBL-free group. Clinical outcomes, including refractive error, visual acuity, and optical quality, in the 2 groups different 1 month after LASIK.

Conclusions:

The incidence of OBL was 8.5% in our study. k reading more than 44.5, corneal thickness more than 530 and a hard-docking technique were risk factors for an OBL. The OBL did not appear to acuity month after surgery.
