Abstract Details


To identify the possible risk factors for the development of posterior vitreous detachment post laser in situ keratomileusis (LASIK) in the Egyptian population.


Ophthalmology department, Assiut university hospitals, and El-Nour LASIK center, Assiut, Egypt.


Prospective interventional case series study including patients with myopic astigmatism who were deemed candidates for LASIK correction. All recruited patients underwent B-scan and A-scan ultrasonography immediately before LASIK using Sonomed. LASIK procedure was done using Allegretto device (wave light EX500, ALCON, Fort Worth, TX, USA) and Moria microkeratome (MM2). One week post LASIK, B-scan was done for all patients for detection of posterior vitreous detachment (PVD).


Sixty one eyes of 31 patients were included in our study. Mean age was 28±5.6 years (range 20-41), mean spherical equivalent (S.E) was -6.1 ± 3.2 D (Range -1.4 to -15.1), mean axial length (AL) was 23.5±1.5 mm (Range 21-26.3). PVD developed in 18 eyes (29.5%). PVD developed more in eyes of patients ≥ 30 years old (odds ratio OR = 4.1, 95% confidence interval CI, 1.2-14.1) and in those with AL ≥ 25 mm (OR = 3.5, 95% CI, 1.1-11.7). Although PVD developed more in eyes with SE ≥ -6 (55.6%) however, this didn’t reach statistical significance (p=0.7).


Older age, longer eyes and higher spherical equivalent were associated with increased incidence of posterior vitreous detachment following LASIK among the Egyptian population.
