Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Other
- 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.
Who the study is looking for
- Group I - FemtoLASIK subgroup:

- 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.
