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.
