To Compare the Clinical Outcomes of FemtoLASIK and ICL Implantation in Treating Moderate Myopia Focusing on Refractive Stability, Contrast Sensitivity and High Order Aberrations.

Inclusion Criteria: Group I - FemtoLASIK subgroup: * Age range: 21-40 years. * Stable myopia for at least one year (refractive change ≤ 0.50 D). * Spherical equivalent between -4.00 D and -8.00 D. * Corneal thickness ≥ 500 μm, residual stromal bed \> 300 μm and percentage of tissue altered \< 39%. * No evidence of keratoconus or ectatic changes on corneal topography/tomography. * Mesopic pupil diameter ≤ 6.5 mm. * Absence of ocular surface disease or significant dry eye symptoms. * No history of prior ocular surgery or trauma. Group II - ICL subgroup: * Age range: 21-40 years. * Stable myopia (with or without astigmatism) for ≥1 year. * Spherical equivalent between -4.00 D and -8.00 D. * Anterior chamber depth ≥ 2.8 mm from endothelium. * Endothelial cell density ≥ 2500 cells/mm². * White-to-white and sulcus-to-sulcus diameters suitable for ICL sizing. * Clear crystalline lens with no signs of early cataract. * No history of intraocular surgery, uveitis, or glaucoma. Exclusion Criteria: Patients with mild myopia (\<-4D) or high myopia (\>- 8D) or hyperopia. * Patients with media opacity. * Patients with associated ocular pathology. * Patients with corneal topography not fitting to either treatment modalities.
