Abstract
Purpose
Aim of this work is to compare the thickness of the laser in-situ keratomileusis flap created by the mechanical microkeratome Moria M2110 and that created with the mechanical microkeratome Moria M290, using anterior segment optical coherence tomography (OCT) (anterior segment OCT 3D 2000 fluorescein angiography plus).
Design
This is a comparative prospective study.
Patients and methods
In our study, flaps were created using the mechanical Moria M2110 with medlogic plano head (intended flap 110 μm) in 38 eyes, and in the other 43 eyes, the flaps were created using mechanical microkeratome Moria M290. Flap thickness was measured using anterior segment OCT.
Results
In the Moria M2110 with medlogic-10 head created flaps, the mean flap thickness 2 mm nasal to the center, the mean flap thickness 2 mm temporal to the center, and the mean±SD central flap thickness were 135.9±6.4 mm (125–160 mm), 137±9 mm (125–163 mm), and 137.7±10.9 mm (125–164 mm), respectively, in right (OD) and 131.2±9.8 (115–152), 129.2±8.4 (116–152), and 131.2±9.8 (117–154), respectively, in left (OS). In the Moria M290-created flaps, the mean central flap thickness, the mean flap thickness 2 mm nasal to the center, and the mean flap thickness 2 mm temporal to the center were 118.4±11.9 (95–145), 118.5±11.9 (96–144), and 118±11.6 (99–145), respectively, in OD and 115.7±12.3 (99–140), 115.9±11.6 (100–139), and 115.8±11.4 (100–140), respectively, in OS.
Conclusion
Laser in-situ keratomileusis flaps created with the Moria M290 have thinner thickness, and more predictability and more perseverance of bed thickness than those created with the Moria M2110.
