Abstract :

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
