Incidence of posterior vitreous detachment after femtosecond LASIK compared with microkeratome
LASIK

Aim:
This is a prospective, nonrandomized comparative unmasked study. The purpose was to compare the incidence of
posterior vitreous detachment (PVD) after femtosecond and microkeratome LASIK.
Methodology:
Eligible patients were chosen between femtosecond and microkeratome LASIK after appropriate counseling.
B-scan ultrasonography was performed before surgery by a single operator. Patients with preexisting PVD (partial or complete)
were excluded. The axial length was also recorded. All surgery was performed by a single surgeon at Rowad Correction Centre,
Cairo, Egypt. During surgery, the suction time was measured. Ultrasonography was repeated 1 month after surgery by the same
operator to detect PVD.
Results:
Ten patients (20 eyes, group M) underwent LASIK using the Moria M2 microkeratome, and 10 patients (20 eyes,
group F) underwent femtosecond LASIK with the IntraLase FS- 150. In groups M and F, respectively, the proportion of women
was 80% and 70%, and the mean age was 24.7±4 years and 25.7±3.3 years, the mean axial length was 24.2±1.2 and 23.8±1.2
mm, and the mean suction time was 18±2 seconds and 63±4 seconds (P=0.001). After surgery, PVD was detected in 4 eyes
(20%) in group M and 17 eyes (85%) in group F (P=0.000044).
Conclusions: The incidence of PVD 1 month after femtosecond LASIK was higher than after microkeratome LASIK. This may
be due to longer suction time during femtosecond LASIK despite lower suction pressure.
