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

T
his is a prospective, nonrandomized comparative unmasked study. The purpose was to compare the incidence of Posterior
Vitreous Detachment (PVD) after femtosecond and microkeratome LASIK. Eligible patients chose 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 one month after surgery by the same operator to detect PVD. The results are 10 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). It can be concluded that the incidence of PVD one 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.
